Trimmer malfunctions
The trimmer is a convenient and affordable replacement for a lawn mower. Its cutting part is made in the form of a fishing line, knives or a disk mounted on a drum, which is closed from above with a protective casing. The basis of the design is a bar, which is adjustable in height, at the end there is a comfortable handle and a shoulder strap.
Like any other technique, the trimmer can break down unplanned, and so that the breakdown does not lead to the final failure of the tool, we suggest that you familiarize yourself with this article. The unit can break down for various reasons. Breakdowns occur both with new trimmers and those that have been used for a long time.
Malfunction of electrical models
The reasons for the unexpected shutdown of the electric lawnmower are associated with a broken cord or a lack of current. In the first case, it is recommended to check the cable for breakage. To replace the power cord, you will need to unplug the power plug, open and remove the switch cover.
Before unscrewing the cable retainer? it is necessary to remember the diagram of its connection to the switch. To disconnect the cord, a hexagon socket (1 mm diameter) is used. The clamp is released, the conductors are removed. A multimeter is used to check the cable for breakage. A new cord is installed if necessary. In this case, the reverse sequence is observed.
In the second case, it is recommended to connect another device to the mains. Electrical devices may not work if the fuse in the plug is damaged. To carry out repair work, you will need to disassemble the plug. For this, a screwdriver and a tester are used.
Motor problems occur when the mower overheats:
- as a result of long-term work;
- overload (the cutting element is blocked by an object).
In the first case, it is recommended to wait a few minutes for the motor to cool down. In the second case, you will need to remove the stuck object. The efficiency of the cooling system depends on the condition of the air filter.
A dirty device does not allow air to pass through well, which contributes to the shutdown of the device. Experts advise to clean and change the filter once every 3 months (with constant use of the lawn mower).
When the electric motor breaks down, there is a corresponding smell and noise. In this case, you will need to replace the drive.
Trimmer Heats Up And Won’t Start
Why won’t the petrol trimmer start? Prerequisites and their elimination
In the near future, the gasoline trimmer acquired the status of the 1st of the main tools in the arsenal of summer residents. And this is logical, because a motorized scythe allows you to quickly put your personal plot in order.
But from time to time it happens that the trimmer does not start on hot or even cool. In such situations, it is necessary to establish the cause of the malfunction without the help of others. Let’s figure out what to do if the trimmer won’t start.
The premises that more often lead to such troubles will be examined further.
The main malfunctions of the car clutch and how to fix them
Good afternoon, today we will find out what is called a car clutch, what are the most common malfunctions.
Quick start. Place the tool so that the air filter is at the top. This trim position ensures that the fuel mixture hits the bottom of the carburetor.
If you remove the air filter before starting and pour a few drops of the fuel mixture directly into the carburetor, then reinstall the filter and cover, then most likely the engine will start on the first try. If that doesn’t work, the problem may be with the spark plug. Possible malfunctions of petrol cutters and how to fix them and much more you can.
Then you need to unscrew it, check its performance and dry the combustion chamber. A non-working plug can be easily replaced with a new one. But, if the candle is in order, the filters are clean, the fuel is fresh, and the scythe still does not start, then you can try to close the air damper, pull the starter once, then open and pull the starter handle several more times.
This procedure is repeated three to five times. With careless handling and excessive zeal, you can damage the starter. If the cable breaks or the handle breaks, then the repair can be done independently, in other cases it is necessary to replace the entire starter.
Engine stalls after starting. Most likely, the carburetor is incorrectly adjusted, or it has been misaligned. That the reason for this can be understood by the vibration during operation. You can adjust the carburetor yourself by following the operating instructions.
The trimmer can also stall if the fuel valve is clogged. Trimmer malfunctions and their elimination | page 27. Then it just clears. If the engine stalls abruptly, it may be difficult to supply fuel to the carburetor. Need to loosen carburetor valves.
Or there is excess air in the carburetor, here you need to add engine speed so that the excess air leaves the fuel system faster. It is also necessary to check the integrity of the fuel intake hose. In case of detection of mechanical damage (cracks, punctures, etc.
), it must be replaced.
Cleaning and storage. The ribs of the cylinder and the channels in the gas trimmer housing must be clean, otherwise it is fraught with overheating of the engine. Allow the engine to cool before cleaning. The outer surface is cleaned with a brush.
Plastic parts can be cleaned with kerosene and other solvents or special products. For long-term storage, the entire mixture is drained from the fuel tank, then the engine is started to use up the remaining fuel in the carburetor.
Store the instrument only in a clean state.
If it was not possible to make repairs with your own hands, it is worth evaluating which is more expedient, contacting a service or purchasing a new trimmer.
The main malfunctions of trimmers: does not start, vibrates strongly, heats up during operation
Outlet duct diagnostics
Stable trimmer performance can be compromised by build-up of dirt in the exhaust duct or blockage in the muffler mesh. This problem most often occurs during the operation of older generation trimmer models. The issue of dismantling the anti-spark grid and cleaning it is being resolved.
The benzokos does not start well, does not develop momentum, heats up
Today in the workshop there is a Polish trimmer Bass Polska. The trimmer does not start well, does not develop speed, it gets very hot and stalls. Bass Polska differs little from well-known petrol cutters, such as: ECO, Defort, Eland, Skiper, Groser, Gunter, KW, Shtenli, Belarus, Ural, Patriot, etc. Therefore, everything that has been said applies equally to these petrol cutters.
How to Fix #Trimmer Blade and Rotor Problem I DIY
The trimmer engine can start poorly, rev poorly, lose power, and stall for several reasons. Most often this is due to fuel system or carburetor problems. Last time we cleaned the carburetor in the AL-KO trimmer (link here), which also developed poorly speed and stalls when throttle was released.
But, in this case, we have one more symptom in the history. the engine gets very hot. There are two most likely reasons why the engine can get very hot.
The first one is a faulty clutch, then the front part of the engine heats up, but the engine is running normally, its rpm and start is OK. The second is a clogged muffler. With a clogged exhaust, there will be a loss of power, and difficult starting, and a loss of power.
The trimmer is practically new, but the compression is lower than it should be. We will not carry out the standard diagnostic procedure, but go straight to the muffler. Remove the protective cover and muffler.
The plugged muffler assumption is confirmed as soon as we removed the protective cover. Exhaust gases under high pressure burst through the muffler bolt. The bolt is burnt and unscrewed with difficulty.
Already by the bolts, the reason for the muffler clogged becomes clear. Less often this happens due to poor-quality two-stroke oil, more often due to the fact that the proportion is not observed when preparing the fuel mixture. Too much oil was poured, the oil did not burn out completely, carbon deposits formed in the exhaust system, which clogged the passage holes in the muffler cavity. This is exactly the case when you spoil the “porridge” with oil, I urge you once again. please strictly observe the proportion of the fuel mixture. The proportion of petrol and oil is usually indicated in the instructions for your petrol tool, as well as directly on the fuel tank cap. In this article, you can learn how to choose and prepare a fuel mixture for a two-stroke engine.
We open the air filter, there was so much oil in the fuel mixture that its remains are clearly visible on the filter element. Wash the filter element in soapy water, blow it with compressed air.
We measure the compression again, with the muffler removed, the compression is normal, therefore, the rest of the engine parts are in good order and suitable for further operation. Usually, in such cases, I just change the muffler to a new one.
The part is inexpensive, so there is no point in washing it in different chemical solutions, wasting time on this, especially since it is not always possible to save the muffler.
It is usual, but not today, today at the request of the client, I will open the muffler, make new holes to replace the clogged ones and weld the formed cavity with electric welding. This is another way to get the trimmer back into operation when the part you need is not available.
We cut the muffler with a thin disc, the pressure inside was so high that one of the baffles broke off. The amount of soot and varnish is amazing.
We drill holes. In this case, I drill with a thicker drill and make more holes. there is no certainty that this tool will continue to be used correctly. Looking ahead, I will say that the engine sound became lower and a little louder, but not significantly. Let me remind you once again that such repairs are extreme and only take place in exceptional cases. Defective part needs to be replaced.
You can’t even see the through hole at the top, it just got clogged with soot.
Further, everything is simple. We weld the muffler body with a low current, a thin electrode. Putting it all in reverse order.
The scythe worked quite a bit, but the gearbox is already making noise, I lubricate the gearbox. The trimmer is good and works great.
