Recovery of electrical equipment
Mowers, inside which the electric motors are located, most often begin to be capricious due to the oxidation of the contacts. The terminals are covered with a layer of scale from excess moisture in the room or in another storage location. It is also worth checking the absence of wire breaks in problem areas. A multimeter or other type of tester is used for this operation.
Dismantling the Electric Lawn Mower
Malfunctions lie in wait for asynchronous motors. Phase-shifting capacitors fail in them. This situation is problematic to diagnose at home. It can be identified by indirect symptoms:
- A humming sound is heard;
- At start the body twitches slightly;
- There is a significant heating of the motor even at low load;
- Turnover decreases.
It is worth diagnosing the state of the toggle switch / button and supplying voltage to the electric motor. When testing the described nodes, and no malfunctions were found, it is unlikely that it will be possible to fix the breakdown of the lawn mower with your own hands. Then you will have to use the services of a corporate service.

Elimination of fuel equipment failures
A simple analysis of failures and malfunctions shows that more than half of them are due to unskilled tuning of the fuel system. Upon closer examination, it turns out that the reasons for the situation when the engine does NOT start, but does not pick up speed and stalls are almost the same.
In most cases, these are:
- Air leaks due to loosening of the screw fasteners or destruction of the crankshaft stuffing box;
- Contamination of the jets;
- Float valve leaks;
- Wear of the booster pump seal.
Summing up.
Definitely, every item we buy has its own expiration date and sooner or later it breaks down, and how annoying it becomes when the degree of its breakdown is so great that it cannot be repaired.
But you must admit that quite often we are simply careless about technology (see.
In correct operation and in how to properly cut a tree so that it falls in the right direction). And when it stops working, then we try to find opportunities to eliminate breakdowns, while contacting a huge number of services.
But remember that although equipment breaks down, we can extend its “life”.
All that is needed is simply to take care of it, do a break-in after replacing parts (read how the chainsaws are run-in, read here) and keep its parts clean and tidy. And then undoubtedly she will last many more years.

When heated
The lawn mower often stops when it heats up. At the same time, it starts up, works “with a jerk” and gradually stops. This process occurs when the gasoline in the carburetor boils or the damper is installed in a rotary rather than a disc type. In the latter case, the part is changed.
It happens that the trimmer heats up if the ignition circuit wire or coil is damaged. In order for the device to start working normally, replace parts.
Immediately after winding up
The unit may stall immediately after starting if the carburetor is misaligned or incorrectly adjusted. this causes an uneven fuel supply. The result of this is that the device vibrates distinctly. For troubleshooting, the carburetor is reconfigured, following the instructions for the mechanism.
Also, the engine stops when the fuel supply valve becomes clogged. In such cases, it is sufficient to simply clean it. If the lawn mower first started working, but then immediately stalled, then the fuel may enter the carburetor unit with some difficulty. Weakening the valve helps to resolve the issue, which ensures free circulation of the mixture in the system.
A stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks) that takes the fuel. In this case, you should add revolutions to the bit in order to quickly expel air bubbles from the system.

Mechanical faults
A sudden stop of the chainsaw can be caused by a seizure of the piston in the cylinder or destruction of the crankshaft bearing due to oil starvation or poor quality engine oil.
In the first case, the performance of the tool can be restored by pouring a few drops of engine oil into the plug hole. Elimination of damage to the crank mechanism provides for complete disassembly in a well-equipped workshop.
Signs of typical failures
If the saw engine does NOT rev up and stalls rather than develops power and stalls under load, it is likely that there is a shortage of fuel or improper carburetor adjustment.
Possible causes include dirty fuel filter or air intake filter element, too rich or poor gasoline-air mixture.
Signs of engine running on a rich mixture:
- Slow set of revolutions;
- Smoke from the muffler;
- Decrease in traction performance and excessive fuel consumption.
The chainsaw stalls when you press the gas. most likely the mixture is too lean.
Lawn mower stalls
When purchasing a lawn mower, you need to be prepared for the fact that, like in all other similar tools, breakdowns may also occur in it, which will require repair.
However, you should immediately run to the service center and pay a lot of money to the masters, convincing you of the presence of a serious malfunction in the device.
