In a private household and in a country house, you simply cannot do without a lawn mower - manually mowing lawns is very long and difficult. Many use electric and gasoline units. Sometimes these devices fail, but there is no need to rush to the service. Do-it-yourself mower repair is possible. If the unit is electric, then most likely the problem lies in the wiring. In the case of gasoline, problems with candles are possible, or the engine has failed.
Electric Lawn Mower Problems
Often any malfunctions with devices of such a plan are associated with violations in the electrical part. Those who are even a little versed in electrics say that the contact has disappeared (or appeared where it should not be). In any case, repairing a lawn mower with your own hands is best to start with a visual inspection. Typical problems include insulation damage or a malfunction of the start button.
Then check the health of the plug and rheostat. If all these elements are normal, it is worth inspecting the electric motor. Often there are problems with equipment with an induction motor. The reason is the phase-shifting capacitor. But the main problem is that at home, repairing a lawn mower becomes impossible. It is very difficult to perform a capacitor test without the proper tools. The fact that the capacitor is faulty can be indicated by the jerking of the electric motor when power is applied, overheating without serious load, low revs and a characteristic buzz.
Gasoline equipment
Repairing a gas mower is more complicated than restoring electrical equipment. But nothing is impossible. It is enough to know typical problems, to be able to diagnose them and replace parts. Most domestic lawnmowers have gasoline push-pull ICEs. Sometimes units can be equipped with motors from other equipment. Often you can find in lawn mowers engines from chainsaws and trimmers.
The most common irregularities in the operation of this equipment encountered by the owners are problems with starting the engine, lack of movement, excessive vibration during operation.
The engine starts, it keeps revs well, and the knives do not spin
This is a very common problem. In this case, the mechanical part fails.
It is worth checking the mount to the motor output shaft. It can be destroyed. Lawnmower repair involves replacing the mounting mechanism.
The engine starts with difficulty, but stably works
In this case, a unit with a gasoline engine starts poorly, but behaves well in the operating mode when fuel is supplied. This is a common reason that is associated with malfunctions in the idle system of the carburetor.
Also, the problem lies in the wrong ratio of the combustible mixture. Repairing a gas mower in this case may not be necessary. Perhaps mixing the fuel with oil in the right proportion will help. If this does not bring the desired result, then you should dismantle the carburetor and adjust the idling system.
The engine starts poorly, unstable operation in any modes
In this case, check the carburetor. Perhaps fuel jets are clogged. Also, the cause may be a clogged fuel or air filter. Lawn mower repair involves cleaning or replacing filters, as well as blowing nozzles.
The power unit starts up but cannot withstand the load.
It happens so. The engine runs fairly well at idle, but at the slightest load they fall. In this case, there is “oxygen starvation”. The solution is very simple - replacing or cleaning the air filter will help.
If the gasoline engine does not start
It happens that even with normal fuel supply, the engine refuses to start.
Most often, problems in the operation of the ignition system. It is necessary to check the coil. It is first examined visually. If there is visible damage, it is best to replace it. Also, the cause may be candles. They are heavily soiled or the electrode is broken. You can diagnose by the candle itself, if you unscrew it. Another effective way of testing is to install a known-good one.
Carburetor cleaning
A carburetor is the most common cause of problems with mowers and other gasoline equipment. Helps cleaning the device. The design of all lawn mowers is about the same. Therefore, you can easily carry out such repairs of the lawn mower with your own hands, regardless of model or brand. The first step is to remove the air filter cover. Having turned off screws, remove a casing from plastic and get the filter. If it is clogged, it should be cleaned. Under this casing there is an inner cover. It will be removed after unscrewing the bolts. Under the cover is a carburetor. It should also be removed. To do this, first of all, disconnect the fuel hose going from the fuel tank directly to the carburetor. If there was fuel inside, it will certainly flow. You need to be very careful. Next, the carburetor is removed - it is held on two bolts. Now that the device is removed, it is necessary to disassemble it. Unscrew the bolt that holds the fuel chamber cap. Cleaning involves the use of special fluids.
But you can get by with the popular option - WD-40. You will also need a thin copper wire. It is necessary for cleaning the fuel channels of the carburetor. You need to clean the device from the fuel chamber. It is recommended to soak the device liberally in liquid for cleaning the carburetor and leave it for a while. This process should be repeated several times. Then, using the copper wire, the fuel channels are cleaned. They can be purged under pressure. Most often dirty cameras or channels. This is the main cause of engine problems. After this operation, even if there were problems with the motor,
the engine might not need to be
repaired at all. After cleaning, everything must be reassembled in the reverse order.
conclusions
As you can see, most malfunctions of garden equipment can be eliminated at home with your own hands. If the lawnmower is owned by a car enthusiast who has set up a car carburetor at least once, then repairing a self-propelled lawnmower for such a person will not be difficult. But it’s better not to bring the device to this state. The key to the smooth operation of the device is high-quality fuel, good oil, compliance with the proportions in the mixture. With the right preparation and high-quality fuel, it is very difficult to spoil a two-stroke engine. If you follow all the rules, then repairing the Huskvarna lawn mower, as well as any other models, will not be needed for a long time.
