Repair and lubrication of a trimmer gearbox for grass

With frequent, intensive use of motorcycles, the gearbox can start to heat up or make sounds uncharacteristic for its normal operation, for example, rattle. This indicates that the mechanism must be lubricated. If this is not done on time, then more serious problems will arise (for example, gears will be quickly worn out and you will need to replace them), up to jamming. Other breakdowns also arise with the transmission mechanism. Reducer repair and lubrication can be performed independently. for this you just need to familiarize yourself with the features of these work and stock up on some available tools.

The gearbox of a trimmer for grass is a node that transfers the rotational movement of the engine shaft to the knife or fishing line. It is located on the lower end of the motorcycle rod. The gear node is also designed to lower the engine speed of the trimmer for grass.

The mechanism consists depending on the model of the motokos of several gears rotating at a high speed. As a result of this, they heat up due to severe friction. If the lubricant is not enough, or it is not at all, then the process leads to a strong overheating and failure of the parts, and, accordingly, the need to carry out a difficult repair. So that this does not happen, lubricate the gear node in time. Misused gearbox is presented in the photo below.

The reducers of modern trimmers of different models from various manufacturers differ from each other by the design and the size of the seat. It happens:

The most common diameters of round seats are 24, 25.5 and 26 mm.

Motokos is equipped with gearboxes with different types of gears:

• conical;
• worm;
• spiroid;
• cylindrical;
• planetary;
• wave;
• combined.

Drive shaft and gearbox are very loaded nodes of a trimmer for grass, which are largely susceptible to wear. Between them, the movement is transmitted due to the adhesion of the teeth of the gears located at different angles to each other. Effective gear works only if there are no mechanical damage. In this case, the mechanism should not overheat, otherwise its jamming may occur.

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.

If the knife ceases to rotate under load or stands still, then this is accompanied by an uncharacteristic sound.

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

How to remove clutch on a trimmer / how to remove a clutch on a benzocosa

• To relieve clutch on a bush (lifting clutch on a gas station. The same thing) must first remove the muffler cover, a metal stand, the starter cover and the cylinder cover so that they do not interfere with the lid of the clutch cover of the bush.
• Remove the lid of the shock absorber (unscrewing two side screws), unscrew the shock absorber clamp bolt and remove the tube from the shock absorber.
• Unscrew 3 or 4 bolts and remove the clutch cover.
• We evaluate the wear of the brake pads and the clutch drum, we see if the spring is broken and check the condition of the bearing.
• To replace, for example, the gripmers of the trimmer for grass (weights), it is necessary to remove the clutch spring, then unscrew the pin bolts on the blocks (if necessary, after blocking the crankshaft, pushing the cable into the hole in the piston is located in the NMT).

While the bureaus is idle, the clutch pads, although they rotate with the crankshaft, do not touch the clutch, since they are compressed by the spring and do not transmit the torque from the engine to the cutting equipment.

When the engine operates at revolutions above the idle pass (above 4000 rpm), the masses of the couplings under the influence of centrifugal force expand (winning the force of the spring) and rests on their outer friction surface inside the clutch drum, they begin to displace it, passing it, passing the torque from the engine on cutting equipment of a bush cutter (or lawn mower).

16 Thoughts about “Clutch of a trimmer for grass. malfunctions, causes and methods of elimination”

Hi, tell me why springs break on the clutch of a trimmer for grass

I think the clutch spring burst, the clutch spring of the trimmer for the grass often breaks due to:

Wear of the pads and, possibly, the clutch drum (which leads to lengthening the spring with longer than with normal operation).

Uneven wear of the pads on one side (spring bend).

Wear of the fixing bushes of the pads (causes backlash back and spring voltage).

Make sure that the fasteners of shoes are tightened and the drum of the trimmer coupling does not swing for the grass.

Incorrect installation of the clutch spring is not possible, inserting the screwdriver into the hole, pulling the spring, trying to insert the ear in the hole in the hole. It is necessary to remove the pads from the braid, hook the ends of the spring behind the holes in the pads, put the overlays in the normal position to each other (in the hands of the inserted spring), then install the overlays assembled with the collection of the braid and tighten the mounting elements (special bolts, preferably new ones, so that new ones are desirable to make it possible They did not unscrew when working).

Incorrect work of a trimmer for grass. The mowing method pressed on gas, released gas, pressed on gas, produced gas due to adhesion of clutch and springs, which leads to its fragility and premature wear of the trimmer coupling. During the mowing, it is necessary to try to maintain the same engine speed, and with the help of a throttle, adjust the speed only depending on the load (depending on the density of the grass).

Removing and disassembling the starter, replacing broken parts

To repair the starter of the trimmer for the grass, you will need to disassemble it first, and then collect it. This process is not a particularly difficult occupation. For work, you will need a screwdriver with the tip of the desired shape.

Everything should be done carefully, observing safety precautions, mainly that the spring does not injure the master if an accident.

Parsing the starting node

They disassemble the launch mechanism in order to install new parts instead of broken in the following sequence:

• spin a screw with a screwdriver, fixing the pulley with a starter lid;
• take out a spring and antennae;
• Remove carefully with the pulley (you need to unscrew the head or work, having dressed the glasses and gloves before);
• determine why the launch mechanism has broken;
• If the spring collapses almost completely, then it is replaced;
• When the spring exits from the hook, it is installed in the original place, bending the antennae before this (the photographs show the laying process);

To change the spring, you should work carefully and accurately: it can, under the influence of the effort caused by the installation of it in place, accidentally burst. Even if you carefully remove the video, then the spring strip flies very quickly from the coil and can injure your hand with its sharp edges.

Immediately putting a springy plate in the same place does not always work. It often slips, so attempts are required to repeat until the desired result is achieved.

Starter assembly

The assembly of the starting node is carried out in a number of stages:

When making the stated manipulations, it is necessary to lay two goals. If this is not done, then the spring over time damage the plastic cup, and when it is pulled. Because of this, a feeling appears, as if the spring had flown. To eliminate such a drawback, you need to install this part of a larger length or an additional goal.

When such spare parts are absent, you can just unscrew the screw a little, and the starter knot will begin to work without shaken. But this option is temporary. it is better to repair qualitatively as quickly as possible.

Spring tension

After installing the spring, it should be pulled. The following actions are performed for this:

• Remove the handle from the starter cord;
• Then the rope is inserted into the coil groove;
• They stretch the spring, rotating the coil in the direction opposite to the clock of the clock arrow (reviews);
• make the desired number of revolutions specified in the instructions for the use of the trimmer model used and the corresponding length of the cord used;
• At the very end, the rope is threaded into a hole designed for this, located in the starter cover;
• put the handle in place, fixing it with a node.

If after the repair the spring continues to fly, then you can get rid of this in the following ways:

• Squeeze the suitable piece of the plate into the groove at the location of the spring hook;
• drill holes on two sides of the groove in the coil, into which the spring hook is inserted and fix it using a wire.

Replacing a torn cord

A torn rope is replaced in the following sequence:

• The old cord is removed;
• choose a suitable rope (thickness and length);
• Having reached it through a special hole in the coil, a knot is tied;
• Sprinkle a spring, producing the required number of revolutions;
• Fix the pen.

It is better to stretch the spring plate along with the partner so that the edge of the cord does not hit the starter mechanism.

It is easy to assemble a starter on a trimmer and wound a spring, only you should do it carefully and with caution. For different models, the gas tanks of the launching mechanisms are the same, so they are repaired in a similar way. In this case, there are some nuances associated with their constructive features.

How to change the clutch cable

To find out how to change the clutch cable, you need to study the instructions well and follow it. Before work, prepare the necessary tools and materials, namely:

• a new copy of the cable (individual for each specific model);
• a jack for lifting a car (it is better if you find a observation hole);
• set of multi.caliber wrench;
• Screwdriver Set;
• For the finish processing of the drive, a lubricant or graphite composition is needed.

To change the drive clutch cable, round.drawers will require.

• Before the dismantling of the damaged mechanism, measure its free part of the lower tip located near the gearbox.
• Move the cable forward. Then remove its tip from the opening of the clutch turning point.
• The cable membrane of the crankcase, located on the surface of the crankcase, remove it from the fixing bracket.
• Directly in the car interior, disconnect the cable tip and clutch pedal.
• Remove the device towards the engine compartment.
• The manipulation of the installation of a new mechanism is similar to actions at the dismantling stages and are carried out in the reverse order.

At the end of the installation of the cable, its initial adjustment is carried out. The following actions must be performed:

• make the interval measured from the clutch fork for the clutch to the damper (the distance should be the same as indicated in the instructions);
• determine the size of the interval between the tip of the cable and the end part of the damper (we check the resulting distance with the recommended leadership);
• in case of inconsistency of the size, make the device adjustment using the adjusting nut;
• Check the adjustment (it is necessary to press the clutch pedal several times, after that make measurements again: in case of non.compliance with the results in the fact that are indicated in the instructions, adjust the re.adjusting);
• At the end, tightly tighten the locknut.

The time you spend on all operations will not exceed 15 minutes. Be sure to, before changing or adjusting the mechanism, read the tips and recommendations of the car factory regarding the repair of the clutch. In addition, it is necessary to find out information about the parameters for adjustment.

As a rule, the clutch cable is equipped mainly by production. Foreign companies prefer hydraulics. Of course, there are foreign cars equipped with a clutch cable. However, such machines are rare.

How much does the clutch cable cost? Given the price of a new spare part for work, you will have to pay about 2 thousand.

What to do if there is no way to change the clutch cable on the spot

If one day happens that the clutch pedal is “lost”, then it is highly likely to say that the cable has broken and it needs to be changed. It is important in this difficult situation not to give in a panic that will not lead to anything good.

First, calmly drown out the car engine. Turn on the emergency signal. If, having looked under the hood, you were convinced that your fears about damage to the details are not in vain, do the following:

• Sit behind the wheel and turn on the first gear. It is quite possible to do this even with a drowned motor and a non.working adhesion pedal.
• Look in the rear view mirror to make sure of your movement. Run the engine. The car should jerk forward, making a few jerks. You must immediately press the gas pedal to start moving.

There is a chance that you will be able to go only at first speed. However, if you have some minimal skills, you can switch transmissions even with faulty adhesion. In this case, you must try to just catch the right moment. To make everything work out, accelerate to the required speed, remove the leg from the gas pedal, set the switching lever to the second gear. Use neutral speed to stop.

In the case of a complete stop, it is necessary to adhere to some rules. The most basic thing is by no means slow down on the lifting in the hill, because it will be very difficult to move, it is almost impossible. In this situation, the battery will not withstand attempts.

It is more correct. to stay on a flat section of the road or under the hill. Of course, the best option is to call the tow truck. Then vehicles will be delivered to the right place where the part will be changed without problems, while the checkpoint will not be damaged.

• If the clutch cable breaks out, this is not a sentence. With such a defect, it is quite possible to go further. But the driver does not always manage to catch the moment and turn on the desired program in time, which is why the checkpoint itself may be slightly damaged.
• Well, if there is an opportunity to get to the parking lot on your own, without outside help. Otherwise, you should dwell on the side of the road and think through your further actions.
• Under no circumstances, it is impossible to stop before the rise, since it will be almost impossible to move.
• Immediately after starting the engine, you should press the gas pedal.

You can rely on these recommendations in other situations. For example, if the squeezed bearing and clutch breakdown damage.

The snow.offer screw does not spin or spin slowly

Problems with the rotation of the screw can be caused by several reasons: cutting protective bolts, insufficient tension or breakthrough collapse of the screw drive, breakdown of the gearbox of the screw mechanism.

Replacing the cuts

The fact that the snowplower screw does not spin, not only the screw belt that broke, but also the cuts of the bolts can affect. The latter are made and soft metal and serve to fasten the screw.

If a rotating screw encounters any obstacle, for example, with a curb or stone, then the bolts are cut off, the screw stops, and you notice that it does not throw snow when the engine is running. Thus, cutting bolts perform a protective function and prevent a breakdown of the gearbox, as well as the screw itself.

Replacing the cuts, if the screw does not rotate, is quite simple. It is necessary to combine the hole on the screw with the hole on the shaft and insert a bolt into it, then fix it with a nut or a spring clamp, as shown in the next photo.

Replacement of the cable of the screw drive

Sometimes the weakening of the screw drive cable becomes the reason that the snowmaker poorly throws out snow. This is due to the fact that the clamping video with a cable connected to it with insufficient force presses the drive belt. Sometimes this cable is torn, which leads to a stop of a snowpock screw. In this case, you will need to replace the cable of the screw drive. First, the cable is removed from the unit handle, and then disconnected from the clamping roller.

Repair of the Schnek gearbox

Repair of the screw, or rather its gearbox, responsible for the transfer of rotational movement to the shaft of the screw, is required when the shaft of the latter does not rotate, or its movement occurs with jerks. The gearbox usually fails due to the natural wear of the gears.

Sometimes the teeth of the gears can break if the user installs on the shaft of the screw instead of trimmed bolts ordinary (metal). In this case, when a mobile screw falls on a solid obstacle, the bolts are not cut off, and the entire load falls on the gear of the gearbox, from which they fail.

In the following photos you can see how the new and worn gear gears look like.

To remove the gearbox, you will need to disconnect the entire snow removal mechanism from the engine. How to remove a screw described above. Next, you should disassemble the screw to get to the gearbox installed on the shaft.

The gearbox body consists of two halves, which are fastened with bolts. After removing the bolts, the case will be separated, and you will see a regular gear and worm installed on the shaft.

Most often, teeth on an ordinary gear break, so it should be removed from the shaft and replaced not a new one.

Advice! Before twisting with each other, two halves of the case abundantly apply graphite lubricant to all gear of the gearbox.

After lubrication, twist the gearbox and collect the entire snow removal mechanism in the reverse sequence.

Repair of the friction ring

The friction ring is a part of the transmission, thanks to which the wheel of a snowman is moving in motion.

The ring is installed on the free wheel wheel.

With the normal operation of the snowproof, in compliance with all the rules of speed switching, the friction ring is subject to very slow wear. But in case of violation of the rules, this element is quickly erased and fails.

The reasons for the wear of the rubber ring of the friction can be the following.

• When operating the unit, the user switches the program without stopping the device. In this case, the rubber seal experiences heavy loads and wear out. With the wear of the ring, a deformation occurs and a metal ring, after which the snowplower machine stops moving.
• The rapid wear of the ring and the appearance of deep grooves on it causes careless control of the unit. That is, the operator allows the wheel slipping, for example, on lifts, on complex sections of the road or in large snowdrifts.
• The friction clutch also wears out due to banal corrosion of the ring as a result of damp. If after work it is not to perform preventive measures to remove snow remnants from this block, then the ring rusts, crumbles, and the friction stops performing its functions.

With the wear of the clutches, the unit begins to go jerking or completely stops. There are also problems when switching the speed of the unit and when switching the direction of movement (back and forth).

Do.it.yourself friction disk repair is carried out as follows.

• Remove the wheels from the unit;
• Remove the crankcase cover by unscrewing 4 or 6 bolts (depending on the model of the device);
• dismantle the chassis;
• Remove the right and left flange (see. The drawing is below). these are covers that cover the bearings;

If not only the ring is worn out, but also the wheel itself, then a complete replacement of the freezes will be required. To replace the rubber ring, unscrew 4 bolts, remove the worn part and insert a new one into the disc, then tighten the fasteners again.

The assembly of the entire friction unit and the snowproof is generally carried out in the reverse order.

How to make repair of the lawn mower with your own hands?

Those who have land are very familiar with what struggle is weed.

Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid for grass.

But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.

The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.

Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.

But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.

The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.

AL-KO, the lawn mower of the company, has serious problems in work, namely: the engine stop without load and its strong overheating, was taken as an example. The motor stops, buzzes and start it again, only re.pressing the “Start” button helps. The button has to restart almost every 30 seconds, and with further work and more often.

Of course, you can work, but it is very annoying and gives the feeling that somewhere the problem is. Therefore, I wanted to figure out where?

After the mower was working within an hour, the engine temperature was measured. It was impossible to touch him with a finger. He directly radiated heat. If you continue to pay attention and continue to work on such a mower, an electric motor will inevitably fail.

It is necessary to determine the cause of the motor overheating. To do this, remove the top cover of the case, under which the engine is located and its power chains.

The lid is held on six screws with a hat under a cross screwdriver.

Unscrew these screws and remove the lid. upward.

Having removed it, you can see the impeller, the capacitor, two connectors and the engine itself.

At first glance, no special problems are invisible. The engine winding darkened slightly from the temperature, but so far it is not critical.

To more carefully inspect the capacitor, it is necessary to unscrew the mount and pull it out.

The capacitor of some external damage did not show.

To check it, you need to disconnect the capacitor and feed the engine for a short time. If he did not start and began to buzz, then the capacitor is intact, because the engine was launched with him. Disconnect the power and connect the container connector back to the engine circuit.

Next, try to twist the impeller. It is mounted on the axis of the rotor and rotates rather tight.

And the reason for such severe rotation is a mechanical brake, which for safety stops the engine rotation when the power is turned off.

It looks like a sleeve that moves freely from top to bottom, along the rotor axis.

Когда напряжение на двигатель не подано, эта втулка прижимается верхней частью о крышку, на которой приклеено две резиновые полосы. Thus, the knife is inhibited on the rotor shaft.

When feeding, the brake sleeve under the influence of the magnetic field is drawn to the center of the rotor and provides free move.

With a careful examination, this sleeve with the brake noticed that at the time of turning on the engine, the brake is retracted and gives the shaft free rotation, but after 2-3 seconds it is released again and begins to slow down the motor. This should not be. Hence the stop of the knife during operation and overheating of the engine.

To find out what is the reason for this work, you need to remove and disassemble the engine.

To do this, disconnect the connectors and put the device on the side to get to the clamping screws. Access to them closes a knife with mounting elements.

To remove it, first you need to unscrew the knife bolt (cm. Figure below).

Direction of rotation, like a regular bolt, and not with left thread. That is, unscrew it counterclockwise, and tighten the clock.

The head of the bolt is plastic, so using the key, it must be well planted so as not to “lick” the edge.

After extracting the bolt, the knife and its plastic disk are removed.

Under it is a height sleeve. With its help, you can slightly lower the knife.

Adjustment is carried out by the washers put under the sleeve (see. drawings below).

We remove everything, only the engine shaft and the hexagonal screws of its fasteners remain.

The key for these bolts has a distance between faces of 6 mm. Unscrew them counterclockwise. Removing the last screw, with one hand, hold the engine.

Next, put the mower on the wheels, and clasping the engine with our hands. we raise it.

To disassemble the motor, you need to free tightening studs. We unscrew them all.

Remove the impeller with two screwdrivers.

We proceed to the removal of the back cover. A wooden block and a hammer will help this.

But first you need to mark the position of the covers with something sharp to the engine body.

Put the engine on the side and hit with a hammer, through a wooden gasket, on the rear shaft.

The motor at that moment should hold another person.

We hit until the axis comes out of the bearing to the end.

How to remove clutch on a trimmer / how to remove a clutch on a benzocosa

• To remove the clutch on the trimmer (removing the clutch on the gas station similarly), you must first remove the muffler cover, the metal stand, the starter cover and the cylinder cover so that they do not interfere with the grip cover of the trimmer for the grass.
• Remove the shock absorber lid (having twisted two side screws), release a bolt, tightening the shock absorber and remove the pipe from the shock absorber.
• We twist 3 or 4 bolts and remove the clutch cover.
• We evaluate the wear of the pads and the clutch drum, we look at whether the spring is broken, we examine the condition of the bearing.
• To replace, for example, the pads (weights) of the gripping trimmer for the grass, you need to remove the clutch spring, and then unscrew the bolts on the blocks (if necessary, after stagnating the knee-deep, stuffing the rope into the candle hole when the piston is in the NMT).

The principle of the centrifugal adhesion of the trimmer for grass.During the work of the trimmer for grass at idle, the clutch pads, although they rotate with the crankshaft, do not touch the clutch drum, as they are compressed by the spring and do not transmit torque from the motor to cutting equipment.During the engine operation at revolutions above the idle (above 4000 rpm), the clutch loads under the influence of centrifugal force are unclenched (overcoming the force of the spring) and resting their external friction surface on the inner surface of the clutch drum, begin to rotate it, thereby transmitting the torque from the moment from the moment from the moment motor for cutting equipment of a trimmer for grass (or lawn mowing).

Problems with the mechanical part

The mechanical system in lawn mowers with different drives consists of the following structural elements and nodes:

• knife (rotary or cylindrical type) or fishing line;
• transmission mechanism;
• grass collector and grass emission devices;
• wheels, handles and housings.

The failure of the cutting element

The most commonly damaged (for example, bend) or knives are blunt, the fishing line for the trimmer ends. This is easily detected with a simple visual inspection.

The fact that the cutting nozzles have become swept away is evidenced by uneven cutting of herbal stems when the lawn mowed.

Over time, knife fastening can weaken. Their balancing during rotation is disturbed, and vibration, whistle, rattling appear. If the knives are damaged, then during operation the mechanism will begin to perform unguided, sudden, sudden movements. To eliminate the malfunctions of this kind, the cutting elements are set to the right position, replaced with new ones or repaired. If possible, then the blades are pulled again.

Sounds and vibration during work

Uncharacteristic sounds, vibration, rattling appear during the operation of the unit, when the fasteners of its structural elements are weakened: body, engine. These phenomena are more often found in gasoline models, because their motor fluctuates more strongly than the electric motor. To eliminate these phenomena, check all the connections, pulling up the bolts if necessary. It happens that the whistle during the operation of the unit arises due to the entry into an outsider that blocks the video in the aerator. In this case, it is enough just to get it so that the sound stops.

Cutting nozzles do not rotate

Often, when mowing a high herbal cover or hard herbal, cutting nozzles cease to rotate due to grass clogging. This problem in most cases (if it has not led to more significant negative consequences) is easy to solve with your own hands, just picking out a stick with a stick.

Damage to constructive details

Damage to the wheels, handles and housing rarely happen. If they are significant, then they change these structural elements. Methods of repair, with its possibility, in each case, depend on the material of broken parts. they can be plastic, aluminum, steel.

Brand break

With prolonged operation, the mower wear out, stretches, and then the belt breaks off. At the same time, the device’s gasoline engine works, but the knives do not rotate. Self.propelled models can also break off the wheel drive belt: then they stop and do not go. Sometimes the clutch cable simply stretches and it needs to be adjusted.

The most common breakdowns

Any technique sooner or later fails. It is important to know how to repair mowers, because not in all cases you need to contact the service center.

The braid does not cut the grass

In most cases, the cause is dumb or severely damaged knives. To achieve the best results, just change the knife every year. Choose a knife suitable for your model. When the knife is swept away, you can sharpen using electrofig or file. When sharpening, be sure to use goggles and gloves. Angle of sharpening on both sides. about 30 degrees.

Simple sharpening devices can be purchased in stores. Before installing them, it is necessary to turn off the mower from the network and adjust the cylinder positions in such a way as to highlight the maximum cutting gap.

In cylindrical braids, the gap between the knife and the cylinder should be less than the thickness of the sheet of paper. Some of the most modern models have built.in regulators with notches. In other cases, you will have to use keys and screwdrivers to carry out the necessary adjustments. Follow the uniformity of the gap along the entire length of the cylinder. To check the adjustment, insert a sheet of paper between the cylinder and a knife, slowly rotating with your hand. Gradually adjust on both sides until the paper begins to cut purely at each point of a motionless knife.

It is difficult to move the mower

• When the mower hardly moves along the lawn, you may try to remove too high grass and you will have to adjust the level of mowing. When seizing rollers or wheels, they need to be inspected to make sure that there are no scraps of grass and garbage. Most likely, they need to be removed and cleaned.
• If an interference for air is formed, then the lifting force will decrease on the mowing air pillow, and it will become difficult to move it. Air lack leads to overheating of the engine. Disconnect the power and remove the remaining grass from the air intake grilles.

The technique does not turn on at all

Long and wet grass can easily block the knives. Pull the fork from the mains and with the help of a wooden object rotate the cylinder to the other side of the knife until the movement becomes free. For gasoline mowers, this technique cannot be used.

A belt that provides the operation of cylindrical lawn mowers, wears out, stretches and can break through. Remove the belt cover and check, there was a gap or belt just jumped off. Unscrew the mounting screws and move the small leading pulley to a large cylinder pulley. Put on a new belt on a small pulley and slowly rotate the big one, gradually putting a belt on it. Push the pulley to the side to stretch the belt, then tighten the screws.

Before installing the lid, be sure to check the belt tension. the degree of bending should not exceed 4 mm (the indicator may fluctuate slightly depending on the model, detailed information is contained in the user guide).

Gap in the cord

With every use, you unfold, move and turn the cord. This can lead to a break in the internal conductors. For many models, the cord is connected to the screw terminals, which makes it possible to quickly check it and replace it. If double isolation, a two.core cord is connected.

Other models use clamping contacts that facilitate the replacement. Disconnect the power, separate the plastic cover. When you unscrew the clamping bar, pay attention to the connection of the cord to the switch to comply with the polarity of the connection (wire color).

In order to disconnect the cord, insert the hexagonal key into each of the holes in which the conductors are placed. to free the clamp and the conductor. Check where the gap has formed.

If necessary, connect a new cord: twist together all individual wiring of each core, then insert the twisted ends into the corresponding terminals. Pull slightly to check the connection. Then install the clamping bar, the cord bushing and the circuit breaker cover.
