Why is the vibration on the trimmer

Before adjustment, you need to painlessly clean the filters according to maintenance in the annotation.

The upcoming setting of the carburetor of the lawn mower with your own hands is made by adjusting screws. There are three of them:

Right (l). adjustment of the fuel consistency for low revolutions.

It is necessary to find the highest speed at idle. To do this, leisurely twist the screw (l) on the right and on the left.

For adjustment, the screw is rotated by a quarter of turnover by all means counterclockwise.

Lower (t). is responsible for adjusting the motor at idle.

For proper adjustment specifically, the idle move is typical:

  • sustainable work of a cool motor;
  • not high speeds of a hot motor;
  • for a trimmer head, there is a lot of revolutions;
  • Sustainable work of the motor when changing the position (sharp rise or descent of the knife).

Husqvarna 525L problem

Left (H). adjustment of consistency at high speeds. (The screw is set up last).

The overall adjustment of the highest revolutions, the power of the motor, temperature and gas consumption depends on the left screw (H).

Setting a carburetor of a lawn mower with the last screw is carried out as follows:

  • Open the throttle to the full, at the same time give out full gas. Turn the screw clock until the time until the speeds fall (in this case, they are oriented by ear).
  • Turn the screw as slowly as possible against the hourly to the uneven operation of the motor.
  • Then turn back at all a little, having heard a measured, even work slightly.
  • For a more pleasant implementation of abilities, it is more convenient to discern the work of the most experienced user:

It is curious that based on the beliefs of the creator of the video, the configuration (its correctness) is determined by the color of the candle, and not just by the turnover and stability of the motor.

True tuning the carburetor with your own hands in this case-combustion of the fuel consistency without a residue, the color of the candle should be light brown.

Cutting the cutting nodes of the lawn mower

The saw settings are stupid over time or wear out. Working with the tool becomes intense, the load increases, the quality of the crook deteriorates. Metal saw canvases are pulled, plastic changes.

If a cutting tool for a trimmer serves as a cutting tool, it gradually wears out, and new material is installed in the reel. The principle of operation of the cutter with a fishing line is concluded in the gradual promotion of the coil under the influence of centrifugal force. When in contact with the grass, the fishing line for the trimmer is abrasion, from the coil is served gradually. A special winding is needed so that two cutting elements come out at the same time and do not get confused with each other.

The figure shows how to properly wind a fishing line for a trimmer to a reel. Before winding a new fishing line for a trimmer is necessary:

  • Taking the nozzle, carefully remove the lid, holding the spring with your hand;
  • From the coil, remove scraps of the old fishing line;
  • measure 5 meters of a new string and fold it in half;
  • in the coil guides at 2 ends, hook the middle part for the recess and wind up in the direction of the shooter for each half of the string;
  • The remaining 20 cm draw through special recesses at the opposite ends of the coil;
  • Install a spring and washers, take the ends of the fishing line outside, close the drum with a lid.

In order to better learn how to change a fishing line for a trimmer on a benzocosa, watch the video.

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen In the area of ​​the engine.

Damage of gasoline trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:

  • engine breakdown;
  • problems with the carburetor;
  • problems with the supply of fuel;
  • muffler malfunction;
  • gearal breakdown;
  • The starter broke;
  • Air filter problems;
  • Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

Basically, the trimmer for the grass ceases to work normally in the following cases:

  • Electric cable malfunction;
  • The control button is faulty;
  • burned engine winding;
  • Contact joints break on the engine.

How to fix vibrations in a mower

Although some lawn mowers should expect a slight rumbling and shaking of the engine, especially when moving along an uneven lawn, excessive vibration from the engine can be dangerous. Vibration can lead to uneven cutting and damage to the engine. Over time, shaking can lead to the bend of the crankshaft engine. If the crankshaft is bent, the mower needs to be replaced. There are other reasons for the engine shaking, not a bent crankshaft, and they can be eliminated in the afternoon.

The vibrating lawn mower is a serious problem that requires immediate elimination.

The lawn mower does not drop turns

You should not buy an expensive and bulky lawn mower to mow grass on a small lawn; It can be easily replaced with a gasoline / electric trimmer. The device of these machines is quite simple, they are easy to use and unpretentious in maintenance. But sometimes problems arise. One of them. When a trimmer for grass does not produce the maximum number of revolutions. Will be discussed in this article.

The reasons

Trammers for grass are reliable and durable (of course, with proper care). Most often, malfunctions arise due to contamination of structural elements.

If the engine of your bush cutter does not start, does not gain speed, does not reach the necessary power or suddenly stops, the reason may be:

  • Low quality fuel (fuel mixture), it can be in long.term storage or not correspond to the recipe of the mixture;
  • Digestive wound on the rod of fishing line / knife head;
  • Cut air filter / muffler;
  • Dysbalance of carburetor.

Ways to eliminate problems

The first three reasons are quite easy to eliminate. If this is a mixture, you need to pour the old fuel from the tank, prepare a new emulsion of high.quality gasoline and engine oil (if your engine needs a mixture) and pour it into a fuel tank. If a trimmer for grass works on clean gas, it’s still easier.

In the second case, the details of the trimmer for the grass should be carefully released from wound grass.

The last reason why the Fergie cell does not work properly will require you a little more knowledge and skills.

Follow the procedure to correctly adjust the carburetor brush. First clean the air filter thoroughly. It is easiest to wash it (it is advisable to regularly rinse the filter with water after 9-10 hours).

Then find the adjusting screws on the diagram of your trimmer for grass, which is in the instructions for the operation of the device. Usually there are three of them: the first is responsible for the supply of fuel, the second. At idle, and the third is designed to limit the number of maximum engine speeds.

Then turn on the device and wait until the engine warms up.

Slowly tighten the first adjusting screw (fuel mixture). Catch the moment when the engine begins to stop, and turn the screw in the opposite direction by 45 degrees. If you do not have time and the engine stops, turn the screw 90 degrees. Open the throttle and see how the speed increases. Then slowly unscrew the screw (each revolution of 45 degrees), until the engine begins to develop maximum speed on full gas.

The second screw, as mentioned above, regulates the speed of the idle speed of the engine. Weakening it, you reduce the number of revolutions, rotate. Increase. The propeller must be adjusted to ensure reliable operation of the engine at low speeds. For better starting, slightly increase the engine speed. At the same time, make sure that the engine makes several tens of revolutions before moving knives / coils with fishing line. If the engine does not start properly, slightly tighten the screw.

After you adjusted the first two screws, check the operation of the device with the maximum engine speed. If necessary, you can limit it (maximum). This will protect the engine from “boiling”. To do this, you need to hook the third screw. Loosen the locknut until the adjusting screw is quietly turned. To increase the maximum number of revolutions, the screw must be unscrewed, reduced. On the contrary, tighten. Fix the nut nut. Check the engine again.

Remember that carbohydrate adjustment is not the final procedure. During the work of the brush, you will probably have to work with it more than once, since the unbalanced carburetor means both increased fuel consumption and quick failure of the ignition, not to mention reducing the power and efficiency of the device.

Little tricks

  • If you cannot tighten / loosen the adjusting screws correctly, this may be due to the fact that the spring is too thick and hard. Then you can choose more suitable.
  • If your device needs not pure gasoline, but its mixture with engine oil, strictly observe the proportions specified in the operating instructions. There is one small thing: the recommended ratio is 1:25 (for all oils) or 1:50 (for “native” oils). Try the first ratio first of all. If, according to this recipe, oil leaks appear on the engine and strong deposits form on the spark plug, half.lubricate the oil. This usually helps to remove traces and reduce the number of soot.
  • To clean the electrodes of the candle from combustion products, you can use fine.grained “sandpaper”. First wipe them with a dry cloth, and then wipe it carefully with sandpaper. If the space between the device body and the insulator is also clogged, its cleaning will help with the help of a conventional unclaimed paper clip. To do this, soak the candle in diesel fuel for a short time, and then clean the dirt. If the blockade is small, one procedure is enough. With strong contamination, it is sometimes necessary to repeat this several times. After thorough cleaning, the spark plug should be wiped dry from diesel fuel residues, and then use for its intended purpose.
  • Please note that the mower (gasoline, electric or wireless) of foreign production requires slightly more care than domestic. In particular, many people strongly recommend entrusting professionals to adjust the carburetor of a two.stroke engine, especially if the guarantee has not yet expired.
  • Finally, one more advice: follow all the recommendations of the manufacturer for the operation and maintenance of the device. Thus, you will continue to work without failures.

What to do if a gas trimmer for grass does not gain speed, you will learn further.

The Stihl 180 chainsaw does not develop speed or after releasing a gas trigger continues to work without slowing down. These problems are quite common. Let’s try to understand the reasons for which the occurrence of such malfunctions is. Also in this article we will consider how to diagnose if the chainsaw does not pull.

Repair of the carburetor

During the inspection of the carburetor, it is worth paying attention to the possible course of the fuel used, to identify the problems of the carburetor, the following measures must be carried out:

  • fuel hose purging to eliminate the possible clogging of the element;
  • checking and replacing the gasket located between the engine and the carburetor;
  • determination of tightness and maintaining constant pressure in the unit.

If necessary, it is possible to disassemble and thoroughly clean the node with your own hand, using gasoline, cleaning the nozzle and channels is used by compressed air.

How the lawn mower works

The principle of operation of a trimmer for grass has the following algorithm:

  • First, the internal combustion engine starts with the starter.
  • The crankshaft of the motor, using the clutch mechanism, transfers rotation to a long axis located in the bar.
  • Flexible or hard long shaft drives a gearbox.
  • The gearbox transfers rotation to the spindle, which is located at the end of the bar.
  • Knives installed on the spindle set in motion.

Gasoline trimmer for grass in the action of Gardenlines.Co.UK

The speed of rotation of the cutting tool is regulated by the gas handle. As a fuel, the lawn mower uses a mixture of gasoline and oil. There are different designs of trimmers. In some combustible materials are poured into a common tank. In others, for each of the species, a separate capacity is provided.

Malfunction of a used trimmer for grass

List of malfunctions of a used lawn mower (gasoline trimmer for grass) with any engine:

For several years, a new trimmer for grass could be launched only after cleaning the candle and purging the cylinder. Dismantling, washing and adjusting the carburetor, the use of gasoline almost without oil (before jerking when stopping the engine) did not lead to a solution to the problem.

The analysis of the cylinder showed that under the gasket separating the cylinder head and the case, the Chinese flooded the sealant. The sealant squeezed out from under the gasket just where the groove is protected, passing the connection place. The influx of the sealant was blocked by the groove. After removing the influx of sealant, the lawn mower began to start without problems.

Buying a remote assumption before disassembling the cylinder and not particularly hoping that the repair will succeed, at the same time I bought a Hopper VS-350 4T gas mower with a four-stroke engine. Before use, I checked the lubricant of the shaft and the lower gearbox. The gearbox was completely clogged with a thick lubricant, the shaft had to be lubricated additionally, and from the ends of the rod to remove the burrs who could break off and get to the shaft.

I confirm what they write about trimmers for grass with a four.stroke engine: less noise, vibration and fuel consumption. Instead of constant preparation of the fuel mixture, you only have to sometimes check the oil level and add if necessary.

Surprise from “Hopra

Since the “Hoper” calmly starts with an open air damper, he did not immediately notice that the air damper lever rubbed the fuel hose at the place of contact almost through:

If you see that the lever of the air damper of your trimmer for the grass rests on the fuel hose, insulate the hose at the site of contact and turn the sharp edge of the lever with a file or sandpaper.

Law out.handies malfunctions and ways to eliminate them

At least what type of benzos has a half bar, in which the binding cable between the motor shaft and the lower gearbox is placed, which transfers rotation to the tool with cutting inventory. In the highest part there is a carburetor and a motor, a gearbox and a working tool closed by a casing are placed on the bottom. In the middle part there is a transverse handle when the control buttons are placed. To unload the hands, there is an unloading belt holding the bar with a torso of the operator.

In the process of choosing a lawn mower, a device with a two.stroke engine is better than a four.stroke. Two.stroke engine is more maneuverable and easier to repair. With a four.stroke node below the level of vibration.

This follows, repair of the lawn mower is to eliminate defects;

  • the engine does not start;
  • The cutting mechanism does not develop;
  • the engine stalls;
  • the gearbox is heated;
  • a third.party knock, powerful vibration of the bar is heard.

For now, eliminate the malfunction, it is necessary to diagnose, find a non.working node.

Know the point of lubrication of the tool in principle. Unchanged care, cleaning the device after work will allow you to extend its service life. Before starting work, you need to tighten the fasteners, cook fuel and season the tank.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

  • unscrew the gearbox located at the bottom of the bar;
  • After removing the gearbox, you will see the end of the shaft, for which you need to pull to extract the part;
  • after extracting the shaft, it must be abundantly lubricated with a special lubricant “Shrus-4” or ordinary-“Litol-24”;
  • Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
  • After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

  • unscrew and remove the mowing head;
  • remove the bar from the electric motor by unscrewing a couple of bolts;
  • Pull out a flexible cable from the bar;
  • Lubricate the cable with grease along the entire length.

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

The main malfunctions of gasoline and electric trimmers

If you do not take into account damage associated with the bar and mowing head, the bush and electric trimmer for grass usually cause malfunctions in the engine.

Damage to gas trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this device:

  • Engine breakdown;
  • Problems with the carburetor;
  • Fuel supply problems;
  • Muffler malfunction;
  • Gear breakdown;
  • The starter is broken;
  • Air filter problems;
  • Cut the fan on the gas tank.

Defective electric trimmers for grass

Since the device of an electric mower is much easier than a trimmer for engine grass, there are little reasons for its failure.

Basically, a trimmer for grass ceases to work normally in the following cases:

  • Electric cable malfunction;
  • Faulty control button;
  • Winding of the burned engine stator;
  • Open contact on the engine.

Why does the gas trimmer not start

The reasons why the gas trimmer for the grass stopped starting can be different, so step.by.step diagnosis of the device is required.

Fuel tank (fuel quality)

Always remember this before starting the device checking the presence and quality of fuel. In this case, do not be greedy and save money, as well as “be smart” regarding the amount of oil added. Everything should be done in accordance with the instructions attached to the device, because if the piston group fails, its replacement will cost about 70% of the total cost of the trimmer for the grass. Refill, hoping that you will use it completely during work. Gasoline left in the tank after a while loses its properties and can damage the engine. Therefore, do not prepare the mixture for further use and in large quantities. If the brush does not work, try to drain the “old” fuel from the tank and fill it with a freshly prepared mixture.

Candle and candle channel

So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is necessary to check the candles channel: whether it throws the combustible mixture. Often, users transfer the air damper to the “off” position when starting and when starting the engine do not install it in the “VCL” position, after which it hardens. Further, an attempt to restart the engine leads to the fact that gasoline flows a candle of ignition, and starting becomes impossible. To diagnose and eliminate the possible problem with this site, follow the following actions:

  • You need to unscrew the spark plug, wipe it well and dry. When installing the spark plug in the engine cylinder, it should be dry.
  • Drain the accumulated fuel from the combustion chamber. This is done through the hole from which you unscrewed the candle.
  • If there is a soot on the electrodes, it should be removed with a thin file or nail file.
  • Be sure to install the gap between its electrodes before replacing the part. The gap on the spark plug should be 1 mm. You can use a coin as an probe to check the gap.
  • Then collect the device, read the start instructions and try to start the engine again.

If the engine does not start, you need to check the spark. For this:

  • Unscrew the candle;
  • Put on it the lid of the high.voltage wire;
  • Touch the metal part to the cylinder body (you can insert a pipe key to provide contact), as shown in the figure below;
  • Pull the starter cord to make several engine speeds.

Usually, with each impact of the piston between the electrodes, the electrodes should slip a spark. If there is a spark, the reason why the engine does not start, you need to look in other parts of the device.

To better understand the process of checking the spark plugs, you can use this video where the test is shown by the example of the Soyuz gasoline baskets.

If there is no spark, then check the cable at the beginning, connecting the spark plug to the coil is probably the reason for this. You can call with the tester. In the case of a chain break, it is necessary to replace the high.voltage wire.

It can also lead to the disappearance of the sparking of the ignition coil (magnetopathic). The figure below shows what the coil (magnet) looks like from the gas trimmer for Patriot grass (Patriot).

The spring may interfere

My first attempt to adjust the gas mowing carburetor did not give anything, since the spring of the fuel mixture adjustment propeller prevented. The factory spring turned out to be too thick in a compressed state and did not make it possible to reduce the supply of fuel to the required level. I had to choose another spring and continue the adjustment after its replacement.

The adjusting screw for feeding the fuel mixture with the spring

In the photo above the factory spring, below the adjusting screw with a selected spring. I am writing about this, because I am not sure that this is an isolated case, and someone else may face the same situation.

From personal experience

lawn mower or trimmer for grass

Trimmer for grass is a broader concept than a lawn mower (lawn mower), since it can also be an electric. The gasoline trimmer for grass and the lawn mower is the same thing.

Some authors assure that a trimmer for grass is a weaker tool, unlike a more powerful lawn mower, which can be used to mow shrubs. Personally, I have a tool with a maximum capacity of 1.7 kW and capable, as stated in the instructions, to mow a small shrub up to 10 mm thick. User manual is called “trimmer for gasoline grass”.

The proportion of the fuel mixture

I read somewhere that if the law mowing manual and the canister with butter indicates different proportions of the preparation of the fuel mixture, the proportion indicated in the manual should be used.

It was done for a long time. excess oil flowed out of the engine to the gas tank and the fiber was constantly formed on the candle, since the leadership indicated a proportion for a running.in engine 1:25, and on the canister. 1:50. After the transition to a proportion of 1:50, the appearance of oil fluxes stopped. The candle continued to burn, but with less intensity (the carburetor has not yet been adjusted).

Until now, some users of the benzo tool determine the fuel mixture “by eye”. If when preparing the mixture the amount of oil is underestimated, after a while an extraneous sound may appear immediately after the engine starts, gradually disappeared during heating, and the engine stop occurs with a sharp jerk. The continuation of the operation of a trimmer for grass in this mode will lead to its failure.

Clead cleaning

In the worst times of the work with a trimmer with an unresolved carburetor, the engine stopped starting after using each fuel tank. And only after cleaning the candle from the car, could you continue to work.

For cleaning the electrodes, fine sandpaper was used, and a thin stationery clip with a bent end was used to clean the space between the insulator and the case. At first, the electrodes were wiped with high dirt with a rag, then cleaned with sandpaper. After that, the candle fell into the diesel fuel and the moistened carpet was opposed by a paper clip from the surfaces of the insulator, the inside of the body and between them. Further, the candle fell several times into the diesel fuel, which then shake off it along with the pollution. Sometimes the procedure for cleaning a paper clip and washing were repeated. After that, the candle wiped dry and was ready for further operation.

Incredibly, one fuel mixture tank with an unresolved carburetor can be spent in less than 10 minutes. verified in practice, when the trimmer for the grass was launched and operated at high speeds with maximum fuel supply (the adjusting screw was unscrewed much more than the norm).
