The right choice of oil for a snow blower is the durability and reliability of your equipment. Initial and regular maintenance of a gasoline snow blower What kind of oil to fill in a patron snow blower

12.10.2019

Works when outside the window is minus temperature. For proper operation, the choice of oil must be based on this, and many other factors. Unlike snow blower oils, which can be used every season (they contain thick additives of the macropolymer type), the winter version is not affected by sub-zero temperatures, its composition does not change, and the viscosity does not decrease even for a certain time.

In addition, oils for the winter period are more affordable than those that can be used every season, due to the fact that they lack all of the listed additives.

Application of snow blower engine oil

Most snowplows are equipped with gasoline engines. In different models, automobile and tractor diesel engines are installed, which are equipped and not equipped with turbocharging.

Snowplows powered by gasoline are more reliable in operation. But it, in turn, requires more thorough care and periodic oil changes.

The more productive the motor, the more snowdrifts it can clear, while throwing snow to the distance you choose. Of course, the fuel and oil consumption of more efficient engines is higher, in addition, they are noisier.

If you plan to clear large areas of snow, then you need to consider the type, type and brand of the motor and snowplow as a whole.

The snow blower consists of:

Engine.
A pump with a mechanical drive, which passes the required amount of snow snow through a special hatch for unloading. Due to its small size, it works very intensively.
Bucket. As soon as the device is turned on, it is the bucket that collects the snow, passing it through many screws.

Professional snow blowers are equipped with sleeved motors, which are characterized by their maintainability. Learn from this article how to make repairs with your own hands.

Choice

What kind of oil to fill in a snow blower so that it works properly? Not many people know that the choice of oil should be based on the engine and its performance. Diesel engines of naturally aspirated snowplows usually use M8g2k and M8DM winter oils.

The latter is good to use for turbocharged diesels.

Many machines are equipped with 1D12BMC1 motors, in which the use of low viscosity oils is contraindicated. In order to lubricate these types of engines, it is necessary to use M-14G2k, in rare cases MT-16p. Cold start with M-14G2k and MT-16p can only be applied if the window is no more than five degrees outside.

If the snowplow has been standing for a long time in the cold or stored outside, then it must be warmed up before starting. During the summer storage of the snow blower, care must be taken to protect the motor from corrosion.

For this purpose, often take used oil - its conservation characteristics are much higher than that of what is placed in a barrel.

When choosing oil for a diesel engine, one of the main values is its brand:

Motor brand: D-242; oil for it: M-8G2k. Not at all like the M-8G2 and M-10G2. It differs from them in effective additive compositions, which provide the opportunity to increase the time required to change the oil. M-8G2k are successfully used in cars of domestic brands.
Engine brand: YaMZ-236M2-4; oil for it: M-8G2k, M-8DM. M-8G2k differs from M-8G2 and M-10G2 types in more effective additive compositions, while it is possible to increase the period indicated for oil change. M-8G2k and M-10G2k are used in KamAZ, ZIL, Ikarus.
M-8DM. It contains a mixture of distillate and residual components that are produced from sour crude oil and new composite additives that improve properties that fight against corrosion and wear of parts. M-8DM is used during winter or summer operation of highly accelerated turbocharged diesel engines

Can be used on naturally aspirated diesel engines where the oil does not need to be changed often.

It is poured, both in domestic and foreign equipment:

Motor brand: 1D12BMC1; oil for it: MT-16p, M-14G2k.
MT-16p oil - used to lubricate naturally aspirated engine diesel engines. Certified in Russia. The oil has the following properties: detergent, antioxidant, anti-corrosion and anti-wear.
M-14G2k. The composition with G2k oil is identical. Scope of M-14G2k:

It is used for transport diesel engines of four-stroke type.

Can be used instead of M -10 G2k oil during summer operation of diesel engines, in regions where summer is long and very hot:

Motor brand: Y-2D6-TK-C5; oil for it: MT-16p, M-14G2k.
Motor brand: YaMZ-238BE; engine oil: M-8DM.
Motor type: YaMZ-238M2; oil for it: M-8G2k, M-8DM.
Motor type: YaMZ-238M2-1; oil for it: M-8G2k, M-8DM.
Motor type: KAMAZ-740.55-360; oil for it: M-8DM.
Motor type: YaMZ-7511; oil for it: M-8DM.

You can also choose Revenol engine oil, which is used for 4-stroke snowplow engines. Top selling oils: Ravenol Schnefrase 4T SAE OW-30 Wollsink and Ravenol M 4T SAE 5W-30 Sinf. The latter belongs to the type of synthetic motor oils of the highest quality.

See the video for more details:

The oil has a light green color and can be used for small-sized 4-stroke equipment that is operated in the winter months. The oil prevents wear during high production and protects the entire machine from rust.

During its use, the technique consumes less hot. This happens due to the reduction of emissions of harmful substances into the environment.

Ravenol m 4T SAE 5W-30 Sinf provides an uninterrupted start in February frosts at temperatures up to -30 ° C, Ravenol Schnefrase 4T SAE OW-30 Wollsink - up to -50 ° C.

The use of these engine oils reliably protects the engine during operation in extreme conditions, protecting the device under heavy load at maximum engine performance.

Ravenol oils for snow removal equipment meet the specifics of work and the requirements of global manufacturers of snow removal equipment, such as MTD, Honda, TORO, Yard-Man, Briggs & Stratton, Murray, Ariens, Kenadian.

Husqvarna snowblower oil is ideal for snowblowers of the same name.

One of the main characteristics of a small is its viscosity.

The degree of viscosity should correspond to the air temperature. If the temperature is from zero to eighteen degrees, use SAE 5W-30 type oil, if the temperature is below eighteen degrees, use SAE 0W-30.

How to change engine oil on a snow blower, where to fill

To calculate how much oil needs to be poured into the engine, read the manufacturer's recommendations and instructions for using the equipment. If the oil is not topped up, the engine will quickly fail, and if it is arrogant, the spark plugs will stop working properly.

Four-stroke type motors work thanks to gasoline (oil is poured into the engine crankcase). Such models can work longer and they start much faster. Fuel is used economically, while the noise level during operation is reduced.

The oil can only be changed when the engine is well warmed up. If the device has been idle for a long time, the engine must first be turned on so that it runs for 5-7 minutes.

The crankcase has an oil filler neck, the cap of which must be unscrewed. If you are doing this for the first time, then it is usually located on the left side of the car.
Before filling in new oil, it is necessary to drain the already used one. To do this, unscrew the drain plug and drain everything that remains there.
It is advisable not to drain the oil on the floor or snow, substitute the necessary reservoir so that the oil does not stain the surface.
Replace the drain plug and make sure it is tightly screwed on.
Now it's time to pour new oil into the oil filler neck. See that the oil level does not exceed the permissible limits.
After you are sure that everything is done correctly, insert and screw back the oil filler cap.

Do not dispose of oil containers that have been drained from the snow blower in places that are not specifically designated for this.

It is also necessary to know that at the time of purchase of snowplow equipment, it is delivered without oil in the crankcase.

So before you get started:

Fill the crankcase with oil.
Adjust the auger and wheel drive system.
Check your tire pressure as it may be too high.
Check the correct assembly of the entire machine.
To make it convenient to fill in the oil, use a special tool for this, a funnel is ideal.

The next step is to check the oil level. To check it, turn off the engine.

The snowplow must not be placed on a hilly surface, the support must come to all wheels. For control, put restrictive shoes.

There is an oily neck on the crankcase of the motor, unscrew it and take the dipstick.
Wipe the oil dipstick with a rag.
Insert the dipstick all the way into the oil filler neck and pull it out sharply.
Thus, you will check the oil level, if necessary, you can add it or, on the contrary, drain the excess.
Screw on the oily neck.

On the dipstick, the oil level will be in the area near the top edge.

Change the oil every 50 hours of operation and at the end of the season.
The very first oil change should be done after 120 minutes of snow thrower operation.
If the engine is running at maximum power, the oil should be changed more frequently than indicated.
Don't forget to dispose of the used oil. As written above, drain the oil into the reservoir and take it to a service station.
In order to prolong the operation of snowplows, lubricate all parts that rotate or move with oil. Do not lubricate friction discs. Add oil also to the chute pivots that eject snow.
To prepare the engine for storage, remove the spark plug and add about 20 ml of oil to the spark plug bore cylinder. Wrap the candle, ignition and smoothly turn the crankshaft of the engine so that the oil is evenly distributed inside.
Also, before storing the engine, wipe its surface with a rag and lubricate it with a thin layer of oil to prevent rust on metal parts.
If you want, for some reason, to hand over the car for warranty repair, be sure to leave a small amount of gasoline and do not drain a little. It is advisable to take with you the packaging of the oil that has been used.
Oil is also used to prevent metal parts from oxidizing.
The oil level must be checked before starting the engine.

Summing up, it can be noted that the right oil for the operation of this technique is very important. The durability and serviceability of the engine system largely depends on it. It is also worth following certain tips and warnings during operation, as they are very important for the normal functioning of the unit.

Snow removal in a small home area is much faster with the use of special snow removal equipment. Its presence greatly facilitates the life of the owners in the winter. All snow blowers can be divided into three types - electric, diesel and gasoline. Gasoline and oil for a gasoline powered snow blower are very important ingredients. Below we will talk about how to choose oil and gasoline, as well as how to lubricate the gearbox and engine.

Internal combustion engines are divided into two types:

two-stroke;
four-stroke.

One stroke is the movement of the piston up or down. For one revolution of the shaft, two cycles are required. Engines in which one revolution of the shaft occurs per operating cycle are called two-stroke. Models with two revolutions are four-stroke. The differences between these engines are not only in design, but also in some other indicators. In particular, there is a difference in the method of lubrication.

In a two stroke engine lubrication is carried out using a mixture that is obtained by combining oil and gasoline in a ratio of 1:25 or 1:50. The mixture circulates in the system and lubricates all the necessary components. After its ignition, the oil is eliminated in the form of combustion products. There are two ways to get a mixture. In the first case, this is carried out directly by the operator, that is, a ready-made version is poured. In the second technique does everything itself. In this case, the engine is equipped with a special oil tank, from which, using a pump, oil in a strictly specified amount enters the nozzle where mixing is carried out.

In four stroke engines mixture is not needed. Oil and fuel enter the system separately. In this case, the engine has a special lubrication system, which includes a pump, filters, a valve and an oil supply line.

Due to the fact that oil burns in two-stroke engines, but not in 4-stroke engines, the requirements for oils for both systems differ. In the first case, it should produce as few products as possible during combustion; in the second case, it should maintain its characteristics for a long time.

Engine lubricant requirements

Buying engine oil for a snow blower requires some knowledge. First of all, you should take into account the conditions in which the snow blower is working - cold. Given the fact that snow removal equipment must operate at low temperatures, the oil must meet certain requirements.

energy saving- its consumption during heating directly depends on this property.
Increased lubrication. For high-quality wear protection, the lubricant must be of a certain viscosity, which will ensure rapid penetration into the grooves between the parts of the mechanism.
Life time. Often no one is interested in changing the oil in the engine, so this criterion should also be paid attention to when choosing.
Versatility. There are oils that are suitable for both diesel and gasoline engines.

An important point when choosing a lubricant is its compatibility with the engine. As a rule, such information is on the packaging. At the same time, different oils are used for diesel and gasoline models.

Types of oils and their features

Oils are divided into three types:

synthetic;
semi-synthetic;
mineral.

mineral oils It is a product of the refining of petroleum. Due to the fact that they contain sulfur, these oils increase the oxidizing properties of the metal. Therefore, the final composition of sulfur should be no more than 1 percent. Various additives are added to increase useful qualities. The cost of such oils is the lowest.

Synthetic oils are obtained by synthesis of various substances, initially have protective properties, are characterized by lower consumption and resistance to extreme loads and temperatures. Due to the costly production, the output is a high price tag. However, the quality of these oils is much higher.

Semi-synthetic- an intermediate link, which is obtained by mixing mineral oils and synthetic oils in a ratio of 70 to 30. They have better characteristics and properties than mineral oils, but are inferior to synthetics. Accordingly, the price tag here is average.

engine's type	Oil type	Characteristics	Price
D-242	M-8G2k	Mineral oil is widely used in Russian cars, it has a large number of useful additives, which increases the time until the next oil change. Suitable for diesel engines. Pour point from -30 degrees.	570 rubles for 5 liters
YaMZ-236M2-4, YaMZ-238M2, YaMZ-238M2-1	M-8G2k, M-8DM	Universal mineral oil, suitable for Russian and foreign assembly equipment, has excellent anti-corrosion properties, has high resistance to extreme temperatures, which makes the replacement period very long. Viscosity change temperature from -30 degrees. Suitable for gasoline and diesel fuel.	1500 rubles for 18 liters
1D12BMC1	MT-16p, M-14G2k	MT-16p is a mineral oil for diesel engines. Protects against corrosion, oxidation and wear. Has certification in the territory of the Russian Federation. M-14G2k - the properties are completely similar.	1800 rubles for 30 liters (MT-16p) 1650 rubles for 20 liters (M-14G2k)

In addition, there are universal lubricants for all types of engines.

Engine oil change

When servicing a snow blower, it is important to know not only how to choose the right lubricant, but also how to change it. Changing the oil in a snow blower has very strict rules. If the equipment is new, then before starting work, you should check the presence of oil. If it is, then you need to pour oil into the snow blower for the first time strictly 5 hours after starting work. The second time this should be done after 25 hours, and then carried out as needed (that is, when it ends).

Replacement is carried out in the following order.

The equipment is installed horizontally on a flat floor.
The snow blower must be run for 5-10 minutes to warm up the existing oil. This makes it easier to drain.
With the engine off, the drain cap is unscrewed.
It is necessary to drain all the liquid into a specially prepared container.
The drain is again plugged with a cork, and the lid and probe are removed from the neck.
Fresh oil is poured.
The cover and dipstick are returned to their place.
After completing all the steps, you need to start the device for a few minutes, and then check the level in the off state.

Gear Lubricant

In order for the snow blower to always work without problems, it is necessary to change the oil in the gearbox. The reducer is an intermediate link between the rotating mechanism of the engine and the screw.

Important! The replacement procedure is carried out every 50 hours of operation of the device. In addition, it is a necessary procedure at the end and beginning of the season.

Reducers are divided into two types: maintained and unattended. The first option implies the possibility of disassembly for cleaning and lubrication. The second option does not require any maintenance, but it serves much less, and in the event of a breakdown it simply changes to a new one.

Snow blower gear lubricant can be applied in two ways.

Oil is poured through a special hole using a syringe.
The gearbox is completely disassembled. In this case, it is possible to carry out not only lubrication, but also cleaning of the internal parts.

In order to disassemble the gearbox, you need to do a number of simple steps:

you need to unhook the belt protection cover and the auger drive cable;
behind the socket for throwing snow, special bolts are unscrewed;
the auger drive belt is removed from the pulley;
the bolts that secure the drive shaft are unscrewed;
after that, the screw and impeller are pulled out;
the auger is attached to the shaft with shear bolts, they must be unscrewed;
the gearbox is disassembled into two parts - for this it is necessary to unscrew all six bolts and, gently tapping the case with a hammer, separate it.

The disassembled gearbox is needed clean with a clean rag and gasoline This helps to remove dirt. After that, the surface must be lubricated with nail polish remover to degrease. After that, the whole mechanism is reassembled and refilled.

Gear oil should not oxidize, be destroyed by temperature or precipitation, it should be slowly consumed and have a long evaporation time. In addition, it must contain special additives that will ensure a long service life of the gearbox and its components.

Lubricant that can be used for a worm gear can be purchased at any auto parts store. By and large, there are no specific brands here, but the most popular among equipment owners is Ravenol. These are affordable and high-quality lubricants. The cost per liter starts from 800 rubles.

Gasoline and fuel consumption

In order to understand which snow blower to choose, it is important to know its fuel consumption. It is worth noting that there are no specific values here. Consumption varies based on engine power, area and topography of the cultivated area, height and density of snow, and the presence of ice. Ideally, a 5.5 hp engine. consumes about 1 liter per hour of operation, models from 7 hp spend about 2.5 liters. On average, this value is equated to 1.5-2 liters. The standard capacity of the petrol tank is between 1.8 and 3 liters. Thus, at one gas station the device can work 1.5 - 2 hours.

The best option for refueling a snow blower - gasoline with an octane rating of 92, in some cases 95 is used. Gasoline should be poured into the snow blower from a clean container. For a two-stroke engine, it is important to get the mixture right.

Advice! Before pouring gasoline, it must be shaken. In addition, you can not fill the container above a special mark.

Correct using and maintaining a gasoline powered snow blower is a guarantee that it will:

effectively cope with any snow;
will last for many years.

If you bought new snow blower, we strongly recommend that you read the instruction manual carefully immediately.

If you bought used a snow blower from your hands, and you were not given an instruction manual, then in this article you will learn:

what routine work needs to be done;
how to identify faults;
what can be repaired by yourself;
for which repair it is necessary to contact the workshop.

To understand how and why it is necessary to maintain and use a gasoline snow blower, you need at least in general terms understand him:

device;
principle of operation.

Base and most expensive part any gasoline snow blower is an internal combustion engine. Most snowblowers have four-stroke motors, however, there are also two-stroke engines.

Both and non-self-propelled gasoline snow throwers are designed in such a way that exclude even the slightest possibility of damage engine.

To do this, the drive from the engine to the gearbox and snowplow mechanism is made using a belt.

The peculiarity of the belt drive is that it.

That is, when the auger encounters an obstacle that is too hard to cut through, the slipping V-belt will prevent the motor from being overloaded and protect it from damage.

Friction the drive is also a kind of protection, because the contact patch of the pressure pad and the friction disc is very small and does not exceed 1 cm².

It is the friction drive that limits the torque supplied to the wheels, as well as the speed of their rotation.

Snow Blower Developers Using Friction Mechanism implemented a variator, in which the transmission coefficient depends on how far the friction disk is moved away from the center of the rotating platform.

Serious minus such a design of a gasoline snow blower is:

extremely weak torque;
rapid wear of the friction disc in 1-2 gears.

In addition, gasoline snow throwers are equipped with two types of augers:

metallic with shear bolts;
plastic covered with rubber.

The first option is cheaper to maintain, because 2-3 shear bolts cost less than even one plastic auger. But the second option is cheaper to manufacture, so the plastic auger is installed on inexpensive non-self-propelled models with a low-power engine.

First maintenance

After you have bought a gasoline snow blower, you need to carry out the first maintenance.

This applies to both unknown Chinese units and snow throwers under well-known brands.

You will lose 1-2 hours for maintenance, but make sure that the device is fully ready for operation or you will find various malfunctions.

After which you will either have to eliminate them, or to return snow blower to the seller and demand:

replacement with a similar but serviceable one;
warranty repair;
refund.

After you have unpacked or unpacked the snow thrower, carefully inspect the machine. It shouldn't have broken wires or bent at a distinct angle cables. After that, carefully check that all bolts and nuts are in place and tightened. This fully applies to both self-propelled and non-self-propelled gasoline snowplows.

You should also have a snow blower detail so you know how to assemble and disassemble your snow blower.

Wrong disassembling and assembling the snow blower can lead to serious damage and complete loss of performance.

Be sure to check if there is included snow blower:

special lubricant for the gearbox;
spare wedge and toothed belts;
spare friction ring;
shear bolts.

If any of the components is not available, buy it. After all, these are consumables that it is desirable to change. every season.

Necessarily lubricate all cables from the inside with a thin low temperature oil, such as spindle oil, or treat with WD-40 fluid.

If the snowblower has electric starter, then check the condition of the contacts and the correct connection of the supply wire.

If you don't know how to check correct wire connection then refer to:

in a specialized workshop;
to an experienced auto electrician.

First maintenance of gearbox and auger mechanism

Check bolt tightness reducer, they should not twist from light pressure on the key. Then unscrew the small hole plug located on the top of the reducer and check that the hole in the plug is not clogged.

Fill the gearbox with grease.

To do this, unscrew the lower (drain) bolt and pour semi-fluid grease through the upper hole.

Depending on the model of a gasoline snow blower, 80 to 200 ml of lubricant will be required.

Exact value look in the instruction manual.

If, after pouring the required amount of grease, the factory grease did not start to come out of the drain hole, then it forgot to fill at the factory.

In this case, keep adding grease until it comes out of the drain hole.

Once the lubrication will appear in the drain hole, screw the bolt into it and tighten with a wrench with a little effort. After that, add another 10–15 ml of lubricant and screw the plug into the upper hole.

Remove all bolts that secure the auger to the gearbox shafts and side bearings and make sure they have slots, that is, the bolts are not ordinary, but shear.

If ordinary bolts are installed, be sure to replace them with shear ones, because if the auger collides with concrete or some solid object, the bolts will be cut off and neither the gearbox nor the motor take no damage.

Remove screws and grease engine oil:

gearbox shafts;
side bearings.

If you have caterpillar snow removal equipment, be sure to check the operation of the lever that changes the slope of the bucket. To do this, with the engine off, move the lever to different positions and measure the distance from the ground (floor) to the bottom of the bucket. A change in distance indicates that everything is in order.

If the distance does not change, contact a shop or certified workshop to have the unit repaired there.

First engine service

Put the snow blower horizontally, then unscrew the plastic oil filler cap and check the oil level. On two-stroke gasoline engines, this operation is not required, because they are supplied with oil along with petrol.

If the oil is in order, then return the plug to its place and unscrew the spark plug.

Gently pull the recoil starter cable a few times - the engine should spin easy and no mess.

Buy from any auto parts store compressometer and measure engine compression.

The normal value is 9–12 atmospheres (0.9–1.2 MPa).

If the compression is less, the piston rings may not have rubbed in yet. In this case, the compression will increase after 5-10 hours of operation with a minimum load.

Compression less than 7-8 after 10 hours of operation under light load indicates that the motor is faulty and unable to deliver nominal power.

This happens due to:

factory marriage;
sale of a poorly restored snow blower.

exchange on the same, only fully serviceable unit;
carrying out the warranty repair;
return money and giving up the snow blower.

First engine start

After making sure that the motor is fully functional, pour into the tank appropriate fuel.

Most gasoline snow throwers run on gasoline AI-92. However, this needs to be clarified in the user manual. There are motors for AI-95 gasoline.

For the first run petrol machine, place the snow thrower in a well-ventilated area. Then do the following:

pump up fuel using the corresponding button.
Translate switch engine operating mode to the on/on position.
Turn the lower lever of the carburetor, which is responsible for supplying fuel, to the right until it stops.
Translate the top lever of the carburetor, which is responsible for the choke, to the right as far as it will go to close the choke.
Translate throttle lever to maximum.
Gently but strongly pull the cable towards you manual starter. If you have an electric starter installed, then connect it to a 220 volt network and press the start button for 1-2 seconds.
If the motor didn't start the first time, pull the recoil starter rope again or press the start button on the electric starter.
As soon as the motor start up, turn the top lever of the carburetor all the way to the left, fully opening the choke.
The motor should run smoothly and at the same speed. Leave it running for 5-10 hours, checking periodically. Listen to his sound. If a metallic knock appears in it, turn off the engine immediately.
Through 5–10 hours mute engine, then let it cool for 2 hours and measure the compression. If the compression was below 7 atmospheres, then in a fully functional engine it will rise by at least 0.5 atmospheres.
After the motor has run 10 hours and cool down, warm up the engine, slate remove the oil from it and fill it with the one recommended by the manufacturer.

First start of auger

This operation can combine with the first start of the engine, and can be performed after it.

You will need to do the following:

Start the engine.
Move the cleaning system activation lever to the on position.
Hold it for 5-10 seconds and ask an assistant to make sure that the auger turns normally. If the auger turns jerkily or does not turn at all on the snow blower, you need to adjust the length of its cable.
Then release the lever, walk around the snow blower and make sure the augers come to a complete stop. If the augers twitch even a little, adjust the length of the cable, this operation is described in detail in the instructions for the unit.
Turn on the auger activation lever and secure with tape or soft copper wire. Let the device run for 1-2 hours without load.
Then stop the engine, release the snow clearing lever, and carefully feel the gearbox. If it is cold or slightly warm, everything is fine. If hot or very hot, then the gearbox is faulty and will soon break.

First engine start

Used on snow blowers three types mover(chassis):

wheel without differential;
with differential;
crawler.

Read more about the differences in the type of propulsion in.

Working with the first type of propulsion comes down to connecting and disconnecting the transmission using the appropriate handle. Therefore, to check, connect and disconnect the corresponding handle several times to make sure that the propulsion unit is working properly.

Wheel drive with differential and crawler drive they work on the same principle - blocking a wheel or track on one side leads to a turn in that direction.

Wheel or track locking system works regardless of gearbox.

Therefore, any transmission can be used for verification.

By manipulating the triggers or handles (depending on the snow thrower model), make sure that the snow thrower follows your commands well and turns accurately in the given places.

When wheels/tracks fuzzy on or off, adjust the length of the respective cables. If the adjustment does not help, contact the store where the snow blower was purchased to have the chassis diagnosed.

Necessarily check tire pressure.

What pressure should be in the tires of a snow blower is indicated:

on the side surface of the wheels;
in the instruction manual.

Maintain the specified pressure in the tires of an approved gasoline snow blower. ±5 percent.

If you have caterpillar unit, then check the tension of the tracks and, if necessary, you will need to either tighten them or loosen them. For a detailed description of this procedure, see the owner's manual for your snow blower.

First application

For the first application, we recommend using dry shallow snow(the height of the snow is not greater than the diameter of the auger). Such snow can be removed in the maximum gear, in which wear of the friction disc is minimal. Start the snow thrower and let it run for 2-3 minutes to warm up the engine.

After that, do the following:

Align the chute in the desired direction. Keep in mind that the distance of throwing snow forward is almost 2 times greater than to the side at an angle of 90 degrees.
Turn on auger.
On the self-propelled device, shift into the highest gear, then connect the chassis and steer the snow blower. Move the non-self-propelled device forward with your hands.
Run the snow blower for 10-20 minutes, then turn it off. When the motor and augers have completely stopped, feel the gearbox, it should be cold. If the gearbox is warm or hot, then there is a problem with it. To check the condition of the gearbox, contact the seller or an authorized dealer.
If the gearbox is cold, operate the snow blower for 1 hour. Make sure it handles the snow easily. Periodically disengage wheel or track drive and shift gears to keep the machine running in different modes. Actively use the differential lock, forcing the unit to turn on its own.
When finished with work, do not turn off the augers and chassis, but do not turn off the motor for 3-5 minutes. This is necessary to dry the case. Then turn off the unit and, making sure that the motor and augers have stopped, feel the gearbox. A cold or barely noticeable warm gearbox indicates that all gears are working, but if it is hot, then the brass gear or grease needs to be replaced.
Using a special shovel, which is supplied with any snow blower, thoroughly clean the snow from the augers, gearbox and rotor. Just as thoroughly clean the body of snow. If you skip this operation, there is a high chance that the gearbox or auger will become covered with ice and you will not be able to start the unit normally.

Weekly maintenance

Petrol snow throwers are reliable and unpretentious devices, so during weekly maintenance it is enough to do following:

check the oil level;
check the fixation of the augers and the condition of the shear bolts;
check the tightness of all nuts and bolts;
check the condition of all cables;
check the beating of the auger;
measure tire pressure;
lubricate all cables with WD-40 fluid or frost-resistant liquid oil.

If the oil level has changed even slightly once, then add oil, recommended by the manufacturer. If you don't have the instruction manual, visit the manufacturer's official website or type in the search engine the question “what oil to use for the snow blower engine (model name)”.

If oil has to be added at least once a month, the engine needs to be seriously checked.

It can be done:

on your own, if you are well versed in gasoline engines;
contacting a certified workshop.

As long as the auger bearings are fully functional, beat in him completely missing.

If beat appeared, then it can be called:

bearing wear;
weakening their attachment.

Overpressure by 0.5–1 atmosphere:

worsens grip on snow and ice;
increases the chance of a wheel explosion.

Monthly maintenance

During monthly service perform All:

weekly work;
daily work.

check the condition of the contacts of the electric starter;
clean the spark plugs and check the condition of the engine on them.

If the motor is running normally, then candle color will be light gray.

Black, red and other candle colors talking about:

problems with the carburetor;
dirty air filter;
poorly working candle;
broken ignition.

At home, without special equipment and knowledge, you can only:

check the condition of the air filter and clean it;
clean/replace spark plug.

In addition, it is necessary remove augers and lubricate shafts gearbox with engine oil. This operation must be carried out with the engine off and the spark plug removed from the spark plug. Read more about this operation in the instruction manual of your snow blower.

During this operation, also lubricate the rest of the auger drive and shear bolt holes.

Another important operation backlash check reducer. To do this, with the engine off, hold the input shaft with one hand, and gently shake the auger with the other.

If the play of the auger does not exceed 1 mm, then everything is fine. If the backlash is 1-2 millimeters, the bronze gear of the gearbox is worn out, but will still work for some time. If the play is more than 2 mm, the gear must be changed, because its teeth can be cut off at any time.

Service before and at the end of the winter season

Maintenance before the start of the winter season should be carried out in the same way as recommended for new equipment.

This will help you find problems. at the initial stage, so the repair of the unit (if necessary) will be much cheaper.

We know from experience that they rarely work longer than 1.5 seasons, so they can fail at any time.

engine oil;
lubricant in the gearbox.

Change the engine oil in the same way as described in the section on starting the engine for the first time.

if you have to clean up a lot packed or wet snow, the oil must be changed at least once a month (not later than after 25 hours of operation).

To change the lubricant in the gearbox, pour into it synthetic engine or transmission oil to fill, then:

start the engine;
turn on the auger drive;
let the unit run for 20 minutes;
turn off the engine and wait for the augers to stop completely;
drain the old grease;
fill the gearbox with new grease recommended by the manufacturer.

It is also necessary before the start of the season:

wash or replace the air filter;
if a fuel filter is installed on the snow blower, then check its condition and replace if necessary;
install new spark plugs.

After the end of the winter season save the snow blower.

For this:

Lubricate all bolts and nuts with a cloth of engine oil. Liberally coat all cables with spindle oil or WD-40.
Start the engine and let it run until the fuel runs out.
Then open the gas tank cap, cover it with a clean rag and leave it like that for a day in a ventilated area. Thanks to this, the remaining gasoline will evaporate and the storage of the unit will be safe.
After that, remove the spark plug and pour 10 ml of engine oil recommended for this engine into the cylinder.

After completing all these procedures, you can install the snow blower into storage.

Diagnostics and repair of faults

All malfunctions of snow blowers can be conditionally divided as follows:

the engine does not work / does not work well;
the chassis does not work well / does not work (the snow blower does not drive);
the screw-rotor mechanism does not work / does not work well.

It happens that the snow blower stalls under load, shoots at the muffler. The list of faults is very long. Some problems can be fixed on one's own, others exclusively In workshop.

If the engine does not work / does not work

If the snow blower engine has started to work poorly, the speed is floating, we recommend that you do the following:

completely drain the gasoline and fill it with a normal one, from a proven gas station;
wash the air filter;
replace the candle;
carefully read the instruction manual, you may forget to open the air damper;
check how the engine turns without a candle;
measure compression.

If these steps fail, and compression below 7 atmospheres, Means:

rings crumbled;
burnt gasket;
burnt valve.

All three malfunctions must be repaired in the workshop, because for this special equipment required.

As you pull the recoil starter, observe how the motor behaves. If it sticks, the crankshaft liner may be seized. This problem can only be fixed in the workshop.

If compression is good and the crankshaft rotates without jamming, you need to check:

ignition system;
carburetor;
muffler.

You can check these parts and systems at home only in one case - if you are well versed in gasoline engines.due to their physical strength.

All malfunctions of such a chassis can be divided into the following categories:

does not go forward or backward;
does not pull;
moves in jerks.

Does not drive in one or more gears

If the snow blower suddenly stopped moving forward or backward in one of the gears, then one of the reasons for this is a misconfigured variator control.

The gear selector is connected to the drive roller of the variator with a special rod, the length of which can be adjusted. You need to remove the protective cover and, shifting gears, watch how the variator rollers move along the friction disc.

In top gear the roller must be in contact with the edge of the disk. In this case, the first forward and first reverse gears will be near the center. If the traction setting is knocked down, then one of the gears will pass through the center.

Another reason for this result is worn or damaged friction disc, due to which the friction ring of the drive roller for some time is torn off from the disk.

To some extent, installing a new friction ring can help, but the only way to completely eliminate the problem is to replace the disc.

It is desirable to perform this operation In workshop.

Doesn't drive or pull in all gears

If the snow thrower does not move or pull in any gear, there are only three possible causes:

wear friction ring drive roller;
weakening belt tension;
cliff belt.

To determine what the problem is on your unit, remove the protective cover and inspect the friction ring.

Without starting the engine, turn on the chassis connection lever, then try to turn the friction disc by hand.

If this succeeds, the belt is loose and needs to be tightened. If the disc spins easily, the belt is broken and needs to be replaced.

Due to the fact that this operation is performed differently on different models of snowblowers, we recommend read the description carefully this operation in the instructions for the snow blower.

During long periods of deep snow clearing, the machine may also start lose momentum.

This happens if the snow:

entered the body;
melted and got between the pulley and the belt.

Belt drive is very sensitive to water.

In this case, do the following:

return the snow blower to the garage or shed;
clear snow and remove all external panels;
remove the belts, thoroughly wipe the pulleys and frame with a dry cloth;
put on dry belts; install all external panels;
make sure there are no gaps between them and the frame.

If the performance not recovered, then the problem is in the auger mechanism of the snow blower, so you need:

disable a screw-rotor mechanism using an appropriate lever;
roll out the unit on a snow-free flat area;
drown out engine;
clear snow device.

After that, you can proceed to the initial examination. To do this, remove the shear bolts and check their condition. If they are sheared, the snow blower auger has hit a hard obstacle and the bolts have protected the motor and gearbox.

Bolt replacement won't solve problems if the obstacle is not removed, because the auger will run into it again and cut off the bolts again.

Therefore, it is necessary to manually remove dangerous obstacle. If this is not possible, then clean the dangerous area with a conventional shovel.

If the shear bolts are intact, you must:

Deliver snow blower in a dry, preferably heated room.
Check auger drive belt and, if necessary, replace it.
dry rag wipe both pulleys.

This operation described in detail in the manual. operating instructions for your snow blower.

A whole and dry belt indicates two possible malfunctions:

weakening fixing the cable connecting the control handle of the auger mechanism and the pressure roller;
damage bronze gear reducer.

The first malfunction can be eliminated by yourself by changing the tension of the cable and determining the moment when the lever starts to clearly turn on the auger mechanism. It is advisable to repair the second malfunction in the workshop, because this requires a lot of experience.

In contact with

With the mass distribution of inexpensive models of snowplows, more and more questions began to arise about their proper operation and timely maintenance. This is not strange, because snow removal machines are mainly equipped with internal combustion engines, which creates special conditions for maintaining the working condition of motors and main mechanisms. Because snow blowers operate in cold or sub-zero temperatures, they require the proper lubricants. It is worth noting that changing the oil in a snow blower is a very important operational point, which must be taken with all seriousness and this operation must be carried out on time.

Engine types and related oil

At the moment, there are two leading types of engines that are universally installed in snowblowers:

Duple. This type of engine runs on a fuel mixture that consists of gasoline/diesel fuel and a special oil.
Four-stroke. This type of engine is more modern, powerful and economical, and also uses only gasoline / diesel fuel for operation. Oil is poured into a special tank and acts as a lubricant.

A very important point is that you need to use the right engine oil for the snow blower. Appropriate markings are always written on the product packaging.

Types of oil and application

At the moment, the market is full of various types of motor oil, which differ from each other in the presence of special additives, operating temperature, viscosity, etc. So what kind of oil should be poured into a snow blower? The answer to this question lies in the instructions that come with the snow blower. Each type of engine, diesel, gasoline, two-stroke or four-stroke, requires special grades of oil, which are used in accordance with the operational characteristics, temperature background and the engine's own technical capabilities. For example, for diesel engines that do not have a pressurization system, it is often recommended to use special winter oils marked M8DM or M8g2k. At the same time, for high quality four-stroke engines, 5w30 synthetic oil is the best choice.

Gear Oil

Like any other mechanism that has moving parts, the gearbox also requires lubricants in it. On the question, What kind of oil to pour into the gearbox, there are many opinions. Often, owners use gear oils and special semi-fluid lubricants. These actions may serve as a denial of warranty service. Therefore, the best gear oil for a snow blower is the one indicated by the manufacturer - a special gear oil. It does not harm the bronze gear, and also does not change its qualities from low or high temperatures.

Optimum oil selection

How to choose the right oil? Since each walk-behind tractor has its own type of engine and its own technical features, manufacturers indicate the most optimal choice of oil for the engine and gearbox. The use of these brands of lubricants from popular companies will be able to maximize the service life of all mechanisms and important components. It is worth noting that the wrong oil for a snow blower can cause a reduction in service life and even damage to the engine and gearbox, so the choice of lubricants should be taken with particular seriousness and attention.

With the advent of budget snowplows, this type of equipment no longer seems so exotic. Removing snow blockages with such an assistant is easy, and most importantly, quickly.

Compare how briskly he coped with his task snow blower.

The most widely represented on the modern market are cars with a gasoline engine. Their power is 6-11 liters. With. The wider the snow grip, the higher the power of the unit should be. Gasoline engines for snowblowers are two-stroke and four-stroke. Two-stroke engines run on a mixture of gasoline and oil.

RAVENOL produces synthetic motor oils for 4 stroke snowplow engines - and

It is necessary to calculate the required proportion in accordance with the recommendations of the manufacturer of the equipment: if the engine is underfilled, the engine wears out quickly, if it is in excess, the spark plugs fail. Four-stroke engines run on gasoline (oil is poured into the engine crankcase). Such units work longer and start them much easier. Fuel economy and low noise levels are another plus in favor of "four-stroke".
