Repair of benzos, gasoline trimmers
In order for the lawn mower to work properly and serves you for a long time, it is necessary to conduct a regular technical inspection, during which existing breakdowns or malfunctions can be detected, as well as those that may occur during future operation.
The consequences of the failure of the lawn mower can be different: from the replacement of a hand starter, to wear of the connecting rod piston group. At the same time, it must be understood that the cost of repairs can be completely different, and sometimes unprofitable.
The specialists of our service have a lot of work experience, so they serve all the well.known brands of benzosos. They cope with the tasks of any level of complexity, quickly reveal the cause of inoperability and quickly eliminate it.
For high.quality diagnosis and subsequent repairs of the benzotrimer, the use of special equipment is required, so we carry out its maintenance in our service zone.

Each tool passes the factory tests, and the carburetor is accurately tuned for maximum performance. Carry out adjustment, only using the exact tachometer (see. data on the number of revolutions per minute). In the absence of a tachometer, it is recommended to carry out only the “basic building” of the carburetor.
Before adjusting the carburetor, clean or over-air filter, start the engine and let it work for several minutes until the operating temperature is reached.
Turn the idle speed controller for the clockwise until the cutting part of the tool starts, then unscrew the screw, turning it counterclockwise until the cutting part of the tool stops rotation. Turn the screw counterclockwise by another 1/4 turnover.
The cutting part of the tool should not turn into idle.
Typical breakdown of echo trimmers
According to Servy statistics, the main malfunctions
- The ECHO benzotrimmer is not started, there is no spark formation of the cause: the spark plug is faulty, the ignition coil (magneto), damage to the parts of the manual starter, the fuel system, wear the cylinder-piston group is faulty;
- The gasoline trimmer for Echo grass stalls, possible causes: blockage of the fuel system (there is no fuel supply), wear of the cylinder-piston group, a carburetor, an air filter clogged;
- The cutting nozzle of the ECHO gasolimmer, the main reasons: wear of the clutch parts (fists, springs, clutch cup), wear of the drive shaft, the gearbox is faulty.
These defects are typical of trimmers (benzos) echo: some are more common, others less often. And not rarely occur due to the simplest reasons: improper operation (no maintenance is carried out), the use of a non-high-quality benzo-mixture (oil and gasoline), the many-hour uninterrupted operation of the trimmer for grass, mowing herbal coating that does not correspond to the technical capacities of the trimmer for grass. However, all breakdowns with the right and professional approach are easy to repair with service specialists.
How to properly serve a motorcycle
The device consists of the following mandatory elements:
Trimmer care involves monitoring the technical condition of each of them.
When caring for a gasoline engine, it is worth paying special attention to the cleanliness of the air filter. it should not have sawdust and dirt. Foam filter should be constantly moistened with oil. Check should be carried out weekly, quickly change the filter as necessary. Before starting each work, you should check how the nuts and screws are tightened. It is also necessary to clean the muffler and candles from the carbon fiber as it is contaminated.
In the electric version, it is enough to follow the operating time prescribed by the manufacturer.
Monitoring of the condition of the fishing line
How to care for the cordial part? The most important thing in this case is the use of a specially designed mowing fishing line.
In no case should you replace the fishing line for a trimmer with metal cables or wire. this is traumatic.
How to monitor the corner gearbox
The priority task of the user is to prevent the accumulation of dirt on it. This circumstance will not allow the details to cool normally. The second requirement is to use consistent lubricant (such as Husqvarna or like), designed for a reducer pair. Usually enough annual lubrication procedure.
What you need to know about the casing to protect
It is forbidden to work without a protective casing. initiative can be dangerous for the user and others. But it is impossible to select such details from among the non.violent, it is necessary to use the recommended by the manufacturer. Damaged casing should be changed in a timely manner.
Casings can be attached both on the bar and on the gearbox. In universal models (working and fishing line and disk) two different kokhuzha are attached. A special cutting plate that cuts off the excess cord can also be located on the “forest”.
We summarize what has been said about the main points of departure in this maintenance of the Hitachi brand Motokos:
Features of the replacement of the wedge belt
Clevel belts are the most common on household self.propelled lawn mowers of the rotary type. Their replacement and adjustment is performed according to the following algorithm:
- Install the lawn mower on the side for convenient access to the drive.
- Remove the protection of the drive mechanism by turning away the screws or by the click of the latch.
- Remove the belt lock near the leading pulley.
- Unscrew the knife fixation screw.
- Gently remove the knife.
- Remove the driven pulley from the shaft with the belt.
- Put on a new wedge.shaped belt on the lead shaft.
- Pre.putting the belt on the driven pulley, install it on the shaft.
- Install a knife in your place and fix it with a screw or nut.
- Install the belt lock in place.
In such structures, the adjustment of the drive belt of the lawn mower is usually not provided.
The principle of operation of the carburetor of the lawn mower
The throttle dashes determines the amount of air for supply, and the engine power directly depends on this.
Fuel is sucked into the carburetor system (its membrane). Then passes through the fitting in the carburetor. Next, the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. The needle valve moves into the membrane chamber.
- Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
- The fuel supply system is necessarily narrowed by a diffuser to increase the flow rate.
- Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Thanks to the pressure drop, fuel penetrates through the jetler.
- Air flow acceleration contributes to the transfer of fuel (gasoline) and its spray. As a result, the air-fuel mixture of the necessary proportion or density is formed.
- The air-fuel mixture penetrates the engine cylinder through the fuel tube.
The level of air density in the system depends on the area of the open air damper. The wider the damper is, the greater the fuel consumption and power.
Simply put, adjusting the carburetor on a benzocos. creating an optimal fuel mixture due to the correct air supply.
How to clean a filter on a trimmer
Sooner or later, there will be a need to rinse the air filter of a trimmer for Husqvarna grass or any other manufacturer. There is nothing complicated, and you can remove pollution from it yourself a couple of hours before mowing.
How to replace an air filter in a trimmer
- Unscrew the bolt on the protective casing or squeeze the latches.
- We take out the filter and inspect. To remove all accumulated oil and other pollution, gasoline will be required.
- We water the gasoline from the canister to the contaminated filter and wash off all the oil. Squeeze and leave to dry for at least 2 hours.
- We wipe the installation site with a cloth moistened in gasoline.
- Set everything in place and close the casing.
Instead of gasoline, you can use soapy water, but it removes dirt still not so effective.
As an alternative to flushing, you can advise blowing or just shaking the litter. These options for cleaning are suitable if there is no oil pollution.
Replacing the crankshaft oil sector, throws oil on the case repair of the gas.suction of the ignition coil
Why change the crankshaft oil seal, how to do it, we look at the order of work on my channel. Why.
The performance of a wheelbanger is several times higher than a manual lawn mower. And managing it is no more difficult than rolling a baby stroller. Just go and direct it. Especially if the lawn mower is self.propelled. Even children will manage with her.
Wheel lawn mowers have a 4-stroke and their maintenance is difficult like a car.
Wheel lawn mowers usually have four.stroke engines. The fundamental difference between four.stroke engines and two.stroke. the presence of a crankcase in which the oil lubrication is located. Therefore, for the normal operation of the 4-stroke engine, you do not need to prepare a fuel mixture of oil and gasoline, it is enough to fill only gasoline into a gas tank. This circumstance is presented by some dishonest sellers as a dignity. “they say, do not mess with the preparation of the fuel mixture”. At the same time, they “sweetly” miss such a detail as the need for at least annual oil replacement in a wheelhouse of a wheeled lawn. The procedure is not complicated, it is much simpler than that of the change of oil in the car, but more complicated than the preparation of the fuel mixture. Generally speaking, the oil in the crankcase of the wheeled lawn mower must be changed about every 50 hours of its operating. The lawn mower is not an oil filter and therefore the oil is not cleaned there. This determines the rapid oil replacement mode. On the other hand. 50 hours of operation of the lawn mower in the season. this is a very big developing.
The process of replacing the oil in a wheeled lawn mower is simple. Before replacing the oil, it is advisable to give the lawnapers to work for 10-15 minutes, so that the oil warms up and becomes more liquid.
In the design of any lawn mower there is a special screw covering the drain hole from the motor crankcase. Usually it is located under the filled and measured neck of the crankcase. (in the photo. indicated by an arrow).
The lawn mower is installed with a slope towards the drain hole, placing wooden churbak or brick under the casing from the opposite side. After that, unscrew the screw. cork. So that the oil does not spill on the casing of the lawn mower, a gutter is cut out of a plastic bottle, according to which the oil will flow into a substituted container. It is advisable to produce gasoline before replacing the oil from the gas tank.
After that, the screw. the cork is unscrewed and the cliff is dragged, tilting the lawn mower. When the oil is draining, the screw is screwed into place. Fresh oil is poured through a measured neck. Typically, it is recommended to use oil with a viscosity of 10W40, mineral or semi.synthetic.
Inexperienced owner of garden motorcycle equipment, of course, is inclined to almost idolize a new purchased technique, up to fetishism. He wants to fill it into it and better gasoline and the oil is more expensive. This is a typical mistake leading to a very quick way out of the technique!
The fact is that this garden technique is made by the “stream”, t.e. The materials in it used the most common, not special. The gaps to the engines are “conveyor”, no one was rubbing anything there. Therefore, you can not pour more liquid oil than recommended by the manufacturer. It simply will not stay in the clearances between the details.
You can not pour gasoline of a higher brand than recommended. Since gasoline with a higher octane number burns longer. And this is fraught with the fifth of the valve, piston or rings.
It is impossible to fill the oil more than the supposedly in the fuel mixture for two.stroke engines (so that it would be better lubricated). The saying “Porridge can not spoil” porridge “here at all. Everything should be in moderation here. In general, carefully read the instructions and follow it, not the advice in Internet forums.
In general, maintenance of both 2 and 4-stroke engines is simple and does not require any special skills or efforts. For two.stroke engines, it all comes down to the preparation of the fuel mixture and cleaning the air filters and ventilation holes. And for four.stroke, service is reduced to annual oil replacement and cleaning water filters. Other annual preparation of the lawn mower for the season are described in another article.
Tips for quickly launching the unit
Under such conditions, it is possible to say about violations in the adjustment of the carburetor.

The tightening of the mounts is to be sent evenly and carefully so that there is no distortion of the carburetor flange. In some cases, tightness disturbances still remain besides at the end of the tightening of the mounting nuts.
In this case, you must clean the place of suction, and replace the gasket in it. If the circumstance of the carburetor malfunction is a breakdown of an accelerating pump, then you will need to come to terms with its replacement. Details of the acceleration pump are not subject to repair.

Replacing or flushing the filter of thin cleaning?
If the resource of the fuel filter has not yet been developed, then it makes sense to tackle it. To do this, use kerosene, acetone or blowing with air from an ordinary pump. However, not all drivers share this opinion and believe that in case of violation of the engine, it is necessary to replace the fuel filter in a timely manner, especially if in the instructions for the car it is ordered to change it through a certain mileage, thereby not creating interference with the operation of the fuel system. over, the cost of such a filter allows you to do this without any difficulties.

Review: Echo SRM 22GES lawners. Not the most powerful unit, but there is enough for a garden plot. Experience for using more than 8 years.
Autumn came, the grass in the garden and on the lawns and it is time to remove trimmers for grass, motorcycles, lawn mowers for the winter.
I have been using an excellent tool on my site for more than 8 years. Motokosa (you can also a trimmer, as many call it) Echo SRM-22GES.
I decided to buy a trimmer for the grass, having a hand.lumpy scythe when I got a site. Over time, I increased the square slightly, having bought the neighboring site. it became equal to 25 acres and, of course, manually bunched off such a volume was unrealistic. While you’ll get from one corner to the other, you need to start again. grass grows quickly in the summer.The question was not yet about to buy a lawn mower, since the surface of the earth on the site was uneven and the lawn mower simply would not have passed through the entire site.
When buying motorcycles of suitable options for selection, there were few. precisely, I considered only two brands. Stihl and Echo. In general, both brands have long gathered their products at China factories, so they turned out to be approximately equal.
The STIHL trimmer was more interesting in that it was possible to immediately buy a nozzle, which, after replacing usual, turned it into a small cultivator. But now the same model is sold, but of course, more expensive.
The tool weighs about 9 kg. This weight is not felt visually, since the dimensions of the motorcycles are great and it is expected that it should be harder.
During operation, the weight is not at all felt, thanks to a very convenient belt, on which the tool is attached.
over, in order to, for example, put a trimmer for grass on the ground, taking a short break in work, you do not need to remove the entire belt over your head. The lawn mower is very quickly fastened and unfastened with a special carbine.
trimmer for grass gasoline. It is equipped with a two.stroke internal combustion engine with a power of slightly less than 1 kW. precisely 0.91 kW. Quite a little, but this is enough for me even to mow small thickets of shrub with a diameter of stems up to 1.0-1.5 cm. To do this, you only need to replace the head with a fishing line with a special three.lobed steel knife, which comes complete with the tool. The diameter of the knife. 230 mm, the diameter of the landing hole. 25.4 mm.
All the necessary tools and installation devices are also available. The main thing. Do not lose the nut that fixes the clamping washer, otherwise it will be to find the replacement for it.
The fact is that the thread here is specific.
If desired, knives with sizes that meet the requirements for installation on a trimmer for grass, you can buy additionally. Depending on the task performed, their configuration will vary. For example, I saw a hay knife that looks like a circle with small radial slots. According to the manufacturer, he carefully cuts off the grass and puts it in an even “roll”. But I have enough of what I have. And it is rarely used now. I even managed to rust a bit.
And earlier, when I had to break through the “clearing” into the thicket of a wild shrub, he helped me very much.
often I use a head with a cutting fishing line.
The diameter of the used fishing line. 3 mm, and you can refuel it almost 3 m, if you carefully lay it.
If stones or large bushes do not come across the grass, about which the fishing line for a trimmer breaks, then on one styling you can mow a very decent area.
The tool works using the AI-92 gasoline fuel mixture and oil with 50: 1. I advise you not to skimp if there is a similar tool, and use the original oil. I experimented with Lukoil 2t for two-stroke engines, but still then returned to the Echo-Wishl. The engine works with it somehow smoother and more stable.
The volume of the fuel tank. 450 ml and this, frankly, is not enough. We have to carry with you a “one and a half” with fuel so as not to run to Saray every half hour. Therefore, only 4 stars for “convenience”.
Air cooling. At a temperature of 32 degrees, I mowed a trimmer quite successfully. But at temperatures close to 0 (this happens in the fall, when the cat is grass for covering the nipes of onion and garlic), the engine works tight. It is felt that there is not enough power. You can, of course, cover the air damper, but then there will be more than more so upwards inside the cylinder.
To start the engine, you need to turn on the ignition by the engine switch and slightly pull the manual starter by the cord.
Usually starts from the first jerk. If the engine did not work for a long time, you need to pump up fuel into the carburetor, clicking on a manual pumping pump.
