How to lubricate the collapsible electitrimmer bar. Necessary tools and materials

Gearbox trimmer for grass than lubricate

For the stable operation of the gearbox without its jamming and regular breakdowns, this mechanism must be regularly lubricated. As the leadership of the economic trimmer for grass indicates, high.quality consistent transmission oil is suitable for this

In some cases, well.known manufacturers of garden equipment produce their oils, which are suitable for lubricating gearboxes of branded trimmers. In order to make these substances as attractive as possible for customers, they are made multifunctional. In other words, such oils are suitable not only for lubricating the gearboxes of household trimmers, but also for regular processing of gears, fuel and oil hoses, as well as maintenance of other details and prefabricated mechanisms, regardless of the type and purpose of garden equipment.

As an example of multifunctional materials-lubrication for the gearbox Motokos Oleo-Mac, for the production of which Molibden Bisulfate is used. Another example is the composition of Liqui Moly LM 47 MOS2. Most often it is used to maintain a CHRUS, however, due to the content of molybdenum disulfide, it can be used to lubricate loaded high.speed bearings, including gearboxes of household trimmers.

An important advantage of multifunctional lubricants is a high content of a large number of necessary additives. Even after the full production of lubricants, they continue to keep a thin and very strong oily film on the surface of moving gears, which protects the details from heating and increased wear

Some trimmers owners use compounds of Lititol-24 types or material for servicing a shus made on a lithium basis to lubricate the gearboxes. Thanks to a suitable consistency, these compounds are easily added to the mechanism using a 5-cow syringe for this. These substances have shown themselves as inexpensive and quite effective lubricants. Their only minus is the need for a more frequent replacement of these fluids.

Shaft for a trimmer for grass: drive, hard, lower shaft for lawn mower (motorcycles) and others

The productivity and duration of the trimmer for grass is determined by the level of modern maintenance. The embodiment of standard operations for caring for the device includes acts that come down to lubricating the gearbox and cleaning the air filter.

After performing the listed actions, you need to make sure that there is no rotation of the bar in the sleeve. Then they run to the lubrication of the gearbox, for what purpose certain gardeners are used solidol. With all this, it will be necessary:

To ensure prolonged introduction of garden technology allows a special lubricant for the gearbox. The well.known auto industry of the Trimmers, including Champion, Stihl, Makita, Husqvarna, produce their own products for care for garden work, which allows excluding the likely difficulties associated with the search and choice of suitable lubricants.

The lubricant must be changed in the gearbox with a frequency of 50 hours of operation of the unit as a result. To clarify more clear data for a specific model, look for its technical passport. Care is needed for the shaft of a trimmer for grass, because it should be cleaned and abundantly lubricated after the purchase.

Before the first launch of the trimmer for the grass, a number of alternate actions are taken:

The embodiment of these actions is recommended not only for new devices, and during the preparation of old units by the next season after storage. If there is no lubricant in a small amount of one otherwise, then this leads to increased friction of the gear part of the gearbox. Since it should work at quite large speeds, the gearbox is checked before the launch of a gasoline trimmer for the grass must often be carried out.

How and how to lubricate the shafts in the rod of motorcycles

Many new motorcycles, even sold in collection, do not have a lubricant on the shaft of the bar. As a result, it warms up, wears out, a light whistling rattle is gradually added to the sound of a working motor and vibration appears. To protect the technique from premature wear, it is enough to devote 10 minutes and just grease the shaft.

First you need to disassemble the bar. In a conventional benzos, it is enough to disconnect it from the upper and lower reducer for this.

If a braid for grass has a collapsible bar, consisting of two parts, then it is even easier. It is only required to remove the connecting coupling in the center and dilute half.

After disassembling 2 shafts, they easily fall out, while the casing of the rods from the gearboxes can not be removed.

If the braid for the grass has already worked, then when examining the shaft, or shafts in the case of a collapsible bar, you can notice scuffs from the central bushings. Such places and need lubrication.

A small amount of lubrication must be squeezed on a rag or fingers and process the shaft without passes. It is applied with a non.weed layer, but everywhere. Particular attention should be paid to the slots, since they are on the highest load, especially at the time of the knife of the knife braid for grass on stones and other objects.

The greased shaft is inserted back into the stack with a slight scroll. Thanks to this, part of the extra lubricant will remain on the central bushings, where it should be. Rotation will also help the hills to get into their seat on the gearboxes.

If a straight lawn mower with a non.vegetable bar is served, then it is simply attached back to the gearboxes. In the case of a two.part bar, short shafts are inserted into each half. After this, part of the rods join the center. If their slots did not hit, then you can simply twist your lower gearbox with your hand. Further, the jointed rod is clamped back with a coupling.

If the lawn mowing is inflow, such a rod maintenance should be carried out every season. The cord’s lubricant used well withstands high temperature, which excludes oil stoops with long operation of braids for grass. The same composition can also be used for lubrication of gearboxes. In them it can be pressed with a syringe if the tube does not have a nose. The lubrication frequency of gearboxes is higher than the shaft. Typically, manufacturers recommend this every 5 mothers.

Engine starting

ICE of household braids are equipped with manual starters. The starter device is simple: a strong cord is wound on a drum that is directly or through a reducer with a crankshaft, the launch is carried out with a sharp stretch of the cord, while the drum is spent, driving a crankshaft, which in turn leads to the launch of the engine. complex models are equipped with a light launch system Flash Starter. This system provides a special clumsy spring, which is twisted through the ratchet by several stretching over the launch cord, accumulating kinetic energy. After that, a special vacation button is released from the latch, the spring is spent with the drum and crankshaft. “Light Start” provides faster launch and less energy consumption of the owner. Also, for quick starting, an additional fuel supply is provided to the carburetor with a special button. To serve an additional portion of gasoline, click on the button once. twice. The reducer of the starter with oil designed to lubricate the gearbox is lubricated.

All these nuances and features of the service and lubrication of the device have already been taken into account by the manufacturer. in the operating instructions, recommendations are given which material can be used for service. Most often, there is not a specific brand brand, but those generally accepted standards to which it should comply with.

If there is no way to purchase the material recommended by the manufacturer, or it is not indicated in the instructions, then the choice of lubricants is made independently.

An important requirement for lubricant is also its ability to remain in the friction zone, not to be dumped under the influence of centrifugal forces during rotation and not squeezed out under load.

Lubrication for the gearbox should have good anti.corrosion properties and reliably protect the nodes from the formation of rust as a result of the effects of atmospheric moisture.

Based on these requirements, the selection of lubricants is carried out.

You can not rack your head, but purchase a specialized tool for servicing electro- or gasoline. Such materials are now in large quantities are offered as manufacturers of motor- and electrical core, as well as other companies.

To facilitate the life of the user, well.known manufacturers sometimes offer universal lubricants that are suitable for servicing the entire garden technique of this brand. You can use such materials.

You can maintain the reducer service with lubricants of general.industrial purpose. The main thing is that they correspond to the operating conditions as much as possible and contain anti.sympathetic additives and filler in the form of solid lubricants (preferably molybdenum disulfide).

Nacsmar200

This tool of the American company NAC was developed for lubricating the angular gearboxes of motorcycle. It is made from mineral oil, thickened by a lithium complex and a special set of additives.

Lubrication has moisture resistance, excellent antioxidant and anti.corrosion properties.

Champion EP-0

This is a universal lithium lubricant with a consistency of 0 according to the NLGI system is designed for gearboxes operating in high mechanical stress conditions.

Lubrication provides long.term lubrication, prevents corrosion, protects from wear of the formation of bully and effectively reduces friction losses.

Lubrication is available in tubes with a volume of 50, 120 and 250 ml.

Hammer Flex 501-027

This special semi-liquid lubricant for gear gearboxes of electrical and benzo-tools with antioxidant, omedinous (EP) and anti-symbolic additives ensures reliable operation of the tool for a long time.

The lubricant penetrates the friction zone well and has excellent lubricant and heat.heating properties, preventing overheating.

Shrus 4

This is mineral lithium lubricant with the addition of molybdenum and additives. The presence of a carrone filler provides it with a high bearing capacity.

Shrus 4 also has excellent anti.zadyr characteristics, good anti.corrosion properties. It maximally reduces friction and minimizes the wear of friction surfaces.

A significant advantage of this material is its low cost.

Lubrication is made by many manufacturers and is available in a wide variety of packages.

Litol 24

Lubrication of Litol 24, like the previous one, was developed back in the USSR and gained great popularity due to the universality of application and accessibility.

This is a purely lithium mineral lubricant without adding any fillers and additives.

There are currently a large number of more advanced lubricants.

It has a low level of operational characteristics, but for a short time it is still capable of performing protective and anti.intelligence functions.

Incredibly low cost makes it still attractive for many owners of garden tools.

Reducer device trimmer for grass

Regardless of the manufacturer and model, the modern trimmer for grass is equipped with a gearbox for changing the angle of mechanical energy between the drive shaft and the head with a fishing line. The most widespread in the benzocos were conical gears, since, unlike straight.tooth, gears with screw teeth are able to carry huge speeds, have a more smooth clutch and have increased bearing capacity.

In the duralumin case (1) there is a shaft-shuster (2) and a gear conical wheel (3), pressed on a driven shaft (4). To reduce friction forces during rotation, rolling bearings (5) are installed at the support points of the shafts. Any gear gear is a highly loaded mechanism, whose duration and reliability of which depends primarily on the lubricant. Therefore, except for the main above the components of the reducer device Trimmer for grass includes a special hole through which you can lubricate the bearings and gears without disassembling the node.

Assortment of lubricants for garden technology

According to the instructions for lubricating the conical gearbox, a special transmission liquid consistent grease should be used. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand as the most adapted to their devices.

At the same time, to reduce the cost of the operation of garden equipment and increase the attractiveness of a brand of auto chemistry, grease for garden equipment usually produces multifunctional. It is intended not only for lubricating gearboxes of gasoline trimmers, but also for processing hoses, transmissions and gearboxes of any garden equipment and mechanical devices operating under high loads.

Such lubricant for the gearbox is sold in the tubes convenient for use and subsequent storage.

Even if a specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.

It should be noted that many owners of the motorcycle in the vast CIS for lubrication of the gearbox use ordinary litol-24 or lubricant for Circus on a lithium basis. It is convenient to refuel the gearbox using a 5-cc medical syringe.

A undoubted plus of the use of lithola and lithium.based lubricant for refueling the transmission of motorcycles is a reduction in operation. But there are nuances because of which spears are breaking on the forums of the Internet gardeners. My thoughts on the topic, what can be lubricated with lubric.based lubricants, and what is not read in the article “Litol as lubrication of the motorcosa gearbox”.

How to lubricate the motorcosa gearbox, gasoline trimmer for grass

Side Bolt on 17 on the gearbox of a gasoline trimmer for grass

In order to avoid random launch, all preventive work on a motorcycle is necessarily carried out with a removed electric cap / plug from a candle. Do not turn the trimmer for the grass to avoid gas leakage.

We unscrew the side screw on the motorcosa gearbox. Depending on the company.manufacturer of a garden tool, instead of a screw for a hexagon, there may be a turnkey bolt, more often at 17. The thread is ordinary, unscrew counterclockwise. Do not lose the sealing puck.

If the lubricant is not visible on the internal end part of the screw, then it is necessary to add 3. 4 grams. Scroll through the gear with your hand, changing the direction of rotation so that the lubricant is distributed through the gears.

Then set the screw in place, tightly tightening it.

Lubrication of the lower gearbox Motokos

The coil gearbox is recommended to lubricate every 10 hours of work. The best lubricant for him, as well as for the shaft of motorcycles, “shus-4” or “litol-24”, designed to work at high temperatures.

To add lubrication to the lower gearbox, we use a disposable medical syringe with a capacity of 5 or 10 ml without a needle:

• We remove the piston from the syringe and disconnect the needle if it was attached.
• Add to the syringe from the piston side the required amount of thick lubricant “shus-4” or “lititol-24”.
• We insert the piston into the syringe and shift the lubricant to the output (drive air).
• The tip of the syringe without a needle is inserted into the lubricant hole and squeeze out the lubricant into the gearbox.

In my guide of the user’s user trimmer for gasoline grass PRORAB 8402R, 8403R, 8405R, 8406R it says that the use of motor oil for two-stroke engines in the amount of 20-30 ml is allowed as a lubricant for the gearbox. But this is not the best option, since the gearbox does not have sealing oil seals and motor oil flows faster than thick lubricants.

Sometimes it is recommended to lubricate the coil gearbox, disconnecting it from the bar, and adding grease until it starts to squeeze out of the gearbox through the coupling. A good option if the gearbox is not removed specifically, but, for example, during the lubrication of the shaft of the lawn mower.

When I disconnected the lower gearbox at the new trimmer for the Hopper VS-350 4T, to remove the burrs at the bar and grease the shaft before starting operation, I noticed that the coupling was flooded with a thick lubricant that was squeezed out of the gearbox. This tells us that there is a lot of lubricants for the gearbox and you can not limit ourselves to the recommended 20-30 ml

How to lubricate the gearbox of a trimmer for grass?

In the upper part of the case, where the gear unit is installed, there is a technological hole that, when operating the trimmer for the grass, is drowned out with a screw. This screw is twisted, and 1.5 2 ml of grease is introduced into the hole using a nose available on a tube. If the lubricant was purchased in another packaging, then a regular disposable medical syringe is suitable for this operation.

After that, the screw is installed in its former place. This procedure, regardless of the user’s recommendations, should be performed every 10 15 hours of operation of a trimmer for grass in working mode. Other reasons for updating or replacing the reducer lubrication are the independent performing of small regulatory work (for example, cleaning and washing the gear of the gearbox before the start of the summer season), repair of the node, preserving the trimmer for grass for the winter period, etc. D.

If the reducer node is disassembled, it is recommended to completely remove the remaining lubricants from the surface of the parts, even if it does not have traces of oxidation and pollution. And only then apply a new grease. After applying the lubricant, it is recommended to handle the shaft several times manually, and make sure that the grease is evenly distributed over all the details of the gearbox.

When lubricating, special attention is paid to the following elements:

• Flywheel: on its surface, as a rule, intensively sticks the remnants of grass, and thickening herbal juice creates additional resistance.
• Dog of a starter coil, which in the process of turning on the drive is constantly in contact with the grooves on the flywheel. At the same time, not only mechanical wear occurs, but also the mechanochemical corrosion of the Makhovik-Sobachka compound, since the materials of this pair are different (the flywheel is aluminum, and the dog is steel).
• Bearings, if their seals are worn out, and through them the remaining lubricants are squeezed out. In this case, the unit begins to vibrate intensively when loading. This happens with trimmers of Chinese.made, so it is worthwhile to think about replacing a bearing unit with a better, for example, from the Swedish company SKF.

Removing and lubrication of the upper shaft of a trimmer for grass

First of all, we remove the lower part of the rod from the connecting coupling, and then disconnect the coupling from the upper part of the bar (here we are talking about a coupling connecting two halves of the bar).

Trimmer for PRorab-8406 grass with a detachable coupling and the lower part of the bar

Now the most interesting thing: on some videos, as on this, holding the ticks of the shaft with ticks, sticking out of the upper part of the bar from below, knock out it with blows on the rods from the rod along with the rolling bearing (here we are talking about the coupling connecting the upper and lower shafts). Some have a gas station with a collapsible bar, as in the video, a coupling connecting the upper and lower shafts, it is put into the rolling bearing.

With our trimmer Prorab-8406 and such a number will not pass like him. They do not have a rolling bearing, and the connecting coupling (sleeve) is a continuation of the shaft of the upper rod. A locking ring is installed in the upper part of this shaft, which must first be removed.

The place of fastening of the upper part of the bar to the clutch clutch body

• We turn off the central screw completely. It fixes the upper part of the bar, partially entering the hole drilled in it. We loosen the side clamping screws and remove the bar from the clutch clutch body.
• We put out the shaft from the upper part of the bar on ourselves how much the backlash allows to get to the stop ring and remove it. A special puller may be needed. We extract a locking ring.

Stop ring on the upper shaft Motokos

• Without a locking ring, the upper shaft is easily extracted from the bar from the opposite side. Lubricate it, not forgetting about the slots in the bushings (couplings) on the shaft of the bar and on the clutch shaft.
• The greased shaft is installed in place in the upper part of the rod and fixed with the locking ring. We insert the bar into the hole of the clutch clutch cover and combine the hole on the bar with the threaded opening of the fixing screw.
• We screw the fixing screw and fix the upper part of the trimmer rod for the grass with side screws in the clutch lid.
• Clean the connecting coupling of the bar from the garbage and install from below on the upper part of the bar.

I don’t have a puller, and I use two large stationery paper clips to extract a locking ring. Previously, they need to be straightened, on one side make a half.ring for the fingers, and on the other. bend small hooks.

In many videos, masters recommend using Shrus-4 grease, this is the best option. In its absence, to lubricate the shaft of the gas mowing rod, you can use Litol-24, which is focused on temperatures up to 130 ° C. But solidol, with the worst lubricants and working at temperatures up to 70 ° C, is not recommended to use.

However, if you urgently need to lubricate the shaft of the rod motorcosa, but there are no suitable materials, then solidol or even ordinary motor oil will be better than nothing at all.

The main malfunctions of the gearbox and ways to eliminate them

With a gearbox of an electric or gasoline trimmer for grass, various breakdowns occur. The most frequent of them are presented in the table further. There you can also find the reasons for their occurrence and methods of elimination.

Bearings are destroyed due to the use of inappropriate lubrication or due to its absence. Their damage is also caused by severe operating conditions of motorcycles and the ingress of extraneous particles of the material (for example, broken metal teeth of mechanical transmissions) due to the fact that the integrity of the anthers is violated.

To remove the bearing, you need to disassemble the gearbox and use a special puller. If it is not, then you can try to do it with a hammer with a mentor. In this case, work should be carefully so as not to damage the seat. Using the pre.heating method to shoot the bearing is not recommended. This is due to the fact that the metal may lose the required operational characteristics.

Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.

Drive engines

Most mowers are equipped with a gasoline engine (ICE), it can be two.stroke and four.stroke, there is no particular difference in them. The four.stroke is more economical and powerful, but more difficult to maintain and more expensive in repair. Two.stroke is easier in maintenance, cheaper, but low.power, consumes more fuel, has a more dirty and noisy exhaust. Combined engines are also found. In addition to gasoline engines, trimmers for grass can be equipped with electric motors, which are connected by a 220V household network with a long cable, but, as a rule, these are domestic devices as they are tied with wires of power to the network.

The role of the gearbox is to transfer the rotational moment from the engine shaft to the cutting tool through 2 gear gears with a different number of teeth. Torque is transmitted at an angle 30. The number of revolutions of the lower cutting disk is less than the engine speed 1.4 times. Gears should be clean and lubricated. There is a hole under the screw to supply oil from above.

First, the place where the cork closes the hole should be cleaned from the ground and grass. To unscrew the cork with the appropriate tool, it is attached complete with a saw. We use consistent lubrication from the tube. Either native lubricant from the manufacturer, or well-known quality compositions, such as OLEO-MAM, is selected.24, Ammol 158. We open the protective layer of the tube and lay the tool on the side. Slowly rotating the knife, squeeze the lubricant into the gearbox body. Gears, turning, spread the composition of teeth over the entire surface. You can also pour a lubricant with a special syringe.

Disadvantage or large amount of lubrication can lead to heating the gearbox. A audible knock and backlash signal the destruction of the bearing or getting dirt due to damage to anthers. The replacement of bearings must be carried out using the shooter, without using the method of warming up.

If the gearbox staggering and travels along the bar, you need to replace the case, or pull the knot temporarily with a clamp to fix it on the pipe. If the knife has stopped rotating, then the gears are not included in the hook. the teeth were demolished or sprinkled. It will require replacing the pair with the full analysis of the node.

When replacing the gearbox, it is necessary to choose a new knot, guided by:

Signs of common faults

Knowing the internal device of the lawn mower and the principle of its operation, you can easily eliminate the malfunctions with your own hands. Some breakdowns are most often found and they are distinguished as the main.

The engine malfunctions should be sought if the lawn mower does not work or does not even start

It is also worth paying attention to this part of the braids for grass, if during operation unusual noises are heard or strong vibration is felt. Clotting of the air filter can also lead to problems with the engine. If the fuel does not enter the combustion chamber, then you should look for the cause in the suction of the fuel filter

It is also worth looking at it if the tool does not work at low speeds

If the fuel does not enter the combustion chamber, then you should look for the cause in the suction of the fuel filter. It is also worth looking at it if the tool does not work at low speeds.

There is no spark. This is often found if the fuel fills the candle.

The bar motorcosa vibrates greatly, because of which the work is complicated by it.

The gearbox in a short time is heated, which is felt during the operation of braids for grass.

At low speeds, it slightly twists a fishing line for a trimmer, which affects performance.

The starter’s grille was clogged. the reason for the engine overheating and its termination. The starter can also fail when the cord tears when it is too sharp.

Carburetor blockage can be due to the use of low-quality fuel

It is also important to pay attention to the carburetor if the mixture flows

The lawn mower stalls after turning off if the carburetor is incorrectly configured.

Malfunction. the knife does not rotate, the coil.

The data transmission of the gasoline consists of a lower gearbox, shaft and upper gearbox (cup). Consider them in more detail.

The gearbox consists of a housing and a gear pair that are susceptible to wear.

This is due to the lack of lubrication in the gearbox.

Do not neglect this procedure during the operation of the lawn mower.

Lubrication control will extend the life of the gearbox.

There are sets of gears for these reducers on sale, but their cost exceeds 60-70% of the cost of the gearbox, moreover, the process of their replacement is laborious, a simple solution will be-replacing the gearbox with a new.

The transfer of traction from the engine to the gearbox is provided by a hard shaft, at the end of which there are slots. Due to the lack of lubrication in the gearbox, slots can be worn out. In this situation, only replacing the shaft with a new

Please note that there are 3 types of shafts (7 slits, 9 slits and “square”). The length of the shaft, as a rule, on such models 152mm. The replacement is very simple. we dismantle the old shaft. install the new

The replacement is very simple. we dismantle the old shaft. install the new.

A clutch cup is installed in the upper gearbox, on which there are slots under the shaft.

In case of wear, it will require its replacement.

The cup can be replaced both separately and the upper gear.

To remove the cup, it is necessary to remove the locking ring (p.49), catching his “ears” in the holes of the cup (n.48).

Please note that on the cup there are also options for the shaft (7 slots, 9 slits and “square”)

The knife or coil at idle rotates (subject to the “correct settings of the carburetor)

With such a malfunction, you will need to replace the clutch spring, or the adhesion assembly.

To replace the clutch, unscrew the upper transmission gearbox. Then unscrew the spark plug and suck the movement of the piston with a special stopper. Unscrew 2 clutch mounting screws (p.57) with washers (p.56), remove the clutch assembly and the washers under it (p.53). Change the spring on the clutch, or install a new. Do not forget to install the washers (p.53) then clutch, and twist the bolts (p.57) with engraver special washers (p.56).

In many videos, masters recommend using lubrication for a clock, this is the best option. In its absence, to lubricate the shaft of the gas mowing rod, you can use lititol-24, which is focused on temperatures up to 130 ° C. But solidol, with the worst lubricants and working at temperatures up to 70 ° C, is not recommended to use.

However, if you urgently need to lubricate the shaft of the rod motorcosa, but there are no suitable materials, then solidol or even ordinary motor oil will be better than nothing at all.

Lower gearbox

On mowers with a drive to a trimmer with work nozzles, a transitional conical gearbox is provided. The transmission of torque occurs through conical genees. This type of gearbox is produced by two types: serviced and supportive. The name is served. the gearbox received from the possibility of adding lubrication to the working cavity for lubricating gears. If the gearbox is not served, then the lubricant is laid by the plant.the manufacturer for the entire service life, and the gearbox itself has a sealed case. According to the developers of the manufacturer, such measures increase the service life of the gearbox, so-as contaminants do not get inside through the non-density of the lubricant. The reducer of the lawn mower is the most loaded part that transfers the force with a change in direction, so the node is very important for the correct care and proper lubrication, what lubricant is needed for the gearbox and the repair of the conical gearbox C = with replacement bearings can be watched by watching a video below.

Stihl lawn mowers are well.deserved popularity

STIHL motokos differ in class, engine type and purpose. Designed for caring for small areas to cleaning large territories from thickets of weeds of shrub and young trees. In this regard, it is customary to divide them into classes. The first class includes amateur vehicles of small power up to 1.2l.With. By design, amateur braids for grass “Stihl” are produced with a curved bar. which allows the lower conical gearbox to exclude from the structure, which significantly reduces the cost of the cost and maintenance. The lawn mower with a curved bar is designed to work with a cutting tool from fishing line or polymer knives. It is convenient to use them in garden areas with small areas.

The second class belong to universal medium.power units up to 2.2 liters.With., intended for field and landscape work. In such designs, a straight hard shaft is used, which allows you to equip this class with saw steel knives for nozzles with help which can be cut down by shrubs and small trees. The design provides for a conical served gearbox. What lubricant to use for the reducer of the lawn mower. A special, under the brand name is the name “stihl” or ordinary lubrication of lip.

Engines from 6.3 to 8 liters.C is intended for professional use in forest or horticultural farms. The name of them is black cutters, these are the most powerful motorcycles for working in large areas, cutting small shrubs and trees. In the arsenal of a working tool there are saw wheels for cleaning bushes with a diameter up to 7cm. Bigorezes are equipped with an anti.vibration system, thanks to which working with such a tool becomes more comfortable. What lubricant to lubricate the gearbox of the lawn mower with powerful drive mechanisms, the lubrication of the Reducer of the Stihl lawn mower is carried out by a special proprietary or grease “STIHL” or production of Litol 24.

Do.it.yourself electrimmer repair: detailed instructions for a novice master with pictures, schemes and photos

For some reason, often the need to carry out the repair of an electrimmer with your own hands arises at the most inopportune moment when it is necessary to urgently mow grass, and the breakdown does not allow this to do this.

Most of the defects that occur is not difficult and can be eliminated literally on the spot with a simple improvised tool. But for this you need to have basic knowledge of the design of your mowing.

How to lubricate the gearbox of a trimmer for grass

Almost every motorcosa gearbox is equipped with a small technological hole, which in the mode of operation is drowned out by a special bolt. After thoroughly cleaning the node from the remains of grass and debris, it is necessary to unscrew the screw and enter the gearbox into the cavity of 1.5 to 3 ml of lubrication depending on the brand of the tool. For the convenience of dosage, you can use a traditional medical syringe. During the operation, it is impossible to allow foreign particles and objects inside the gearbox, since this can lead to intensive wear of the gear gear, as well as its jamming.

Experts recommend, when completing the mowing season and long.term storage of the tool without work, to disassemble the gearbox, flushing gears and bearings, as well as re.lubricating the node.

How to lubricate the gearbox gearboxes

Buying any equipment in its kind is a lottery, but much also depends on the gardener. In caring hands and Chinese samples serve for a long time and do not let their owners at the wrong time. And if you forget to lubricate the motorcosa gearbox in time, do not clean filters, use cheap low.quality gasoline, then garden equipment from the most eminent brands will be a headache.

Lubrication of the gearbox Motokos is one of the most important elements of maintenance of a gasoline trimmer for grass, which the user should be carried out directly.

Time and procedure for the prevention of the gearbox

I recommend that the prevention of a new gasoline trimmer for grass immediately after purchase, with the addition of lubrication in the gearbox. For all the high cost of garden technology, some manufacturers save and lay lubrication only at a minimum, for the duration of the run.in.

How often to lubricate the gearbox motokos

Often, a preventive inspection of the transmission with the addition of liquid consistent lubrication is carried out once a year at the beginning or end of the season. If the gasoline trimmer for grass is used not in professional volumes, this is enough.

With large volumes of the mowing, lubricate the motorcosa gearbox every 20-50 hours of work. If the conditions of the operating mode of garden equipment are difficult, for example, a large field is pumped out at a time, and at the same time the lawn mower does not have time to cool down, or cheap lubricants are used, then the lubricant must be checked and added every 20 hours of work.

Indirect evidence that it is necessary to lubricate the gearbox to overheating or increased noise of the node.

I also recommend a complete replacement of lubrication, with disassembly and flushing of the node, when buying a used gasoline trimmer for grass.

Assortment of lubricants for garden technology

According to the instructions for lubricating the conical gearbox, a special transmission liquid consistent grease should be used. As a rule, manufacturers of garden equipment produce and recommend the chemistry of their brand as the most adapted to their devices.

At the same time, to reduce the cost of the operation of garden equipment and increase the attractiveness of a brand of auto chemistry, grease for garden equipment usually produces multifunctional. It is intended not only for lubricating gearboxes of gasoline trimmers, but also for processing hoses, transmissions and gearboxes of any garden equipment and mechanical devices operating under high loads.

Such lubricant for the gearbox is sold in the tubes convenient for use and subsequent storage.

Even if a specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.

It should be noted that many owners of the motorcycle in the vast CIS for lubrication of the gearbox use ordinary litol-24 or lubricant for Circus on a lithium basis. It is convenient to refuel the gearbox using a 5-cc medical syringe.

A undoubted plus of the use of lithola and lithium.based lubricant for refueling the transmission of motorcycles is a reduction in operation. But there are nuances because of which spears are breaking on the forums of the Internet gardeners. My thoughts on the topic, what can be lubricated with lubric.based lubricants, and what is not read in the article “Litol as lubrication of the motorcosa gearbox”.

Side Bolt on 17 on the gearbox of a gasoline trimmer for grass

In order to avoid random launch, all preventive work on a motorcycle is necessarily carried out with a removed electric cap / plug from a candle. Do not turn the trimmer for the grass to avoid gas leakage.

We unscrew the side screw on the motorcosa gearbox. Depending on the company.manufacturer of a garden tool, instead of a screw for a hexagon, there may be a turnkey bolt, more often at 17. The thread is ordinary, unscrew counterclockwise. Do not lose the sealing puck.

If the lubricant is not visible on the internal end part of the screw, then it is necessary to add 3. 4 grams. Scroll through the gear with your hand, changing the direction of rotation so that the lubricant is distributed through the gears.
