- Once maximum speeds are reached, screw L will need to be turned 1/4 turn in the opposite direction. If during this the saw chain starts to rotate, then screw T should be turned counterclockwise until the chain stops completely:
- Screw H is adjusted at a 10-second interval at maximum engine speed. In this case, the screw should be gradually turned 1/4 turn in the direction of the clock. If during this the saw motor does not gain maximum speed, then the screw will need to be turned again 1/4 turn. Too low revolutions will be accompanied by a loud screeching of the instrument, and too high revolutions will be accompanied by an increase in the amount of exhaust gases;

Husqvarna 142 chainsaw malfunctions and troubleshooting
There are a number of typical failures that owners of the Husqvarna 142 chainsaw most often encounter. In order to be able to perform their own repairs, you will need to understand the symptoms of the problem and find the defective part.
What to do if the Husqvarna 142 chainsaw does not start?
The most common cause of this problem is the spark plug. If the saw does not start either cold or hot, then you need to carefully inspect the candle.
If the candle is completely dry, then the fuel does not pass into the cylinder. In this case, you need to inspect the fuel pipes along which the fuel must circulate. Defective hoses will need to be replaced and the engine cylinder cleaned of carbon deposits.
If a soot and a large amount of fuel were detected on the spark plug, it means that the fuel fills the part during startup. To fix the problem, you need to unscrew the candle, clean and dry it. The entire interior space under the part must also be blown with compressed air from the container and wiped with a towel.
After the performed steps, the Husqvarna 142 will start from the first or second time. To prevent the occurrence of such problems, you should use only high-quality gasoline and oil to refuel the tool.
Chainsaw starts and stalls. Repair methods
If the Husqvarna 142 starts up and immediately stalls, the main reason for this lies in the wear of the rings, which leads to loss of compression. If the engine starts and stalls during cold start, then you should check the muffler, as well as the contact between the high-voltage wire and the spark plugs.
To fix the malfunction, you will need to disassemble the saw, and inspect the piston rings. If necessary, they must be replaced. It will not be superfluous to clean the cylinder walls of the remaining fuel.
If the rings are working, then you need to inspect the contact between the spark plugs and the chainsaw wire. You also need to clean remove the muffler and inspect its walls. As a result of prolonged use of the tool, a thick layer of soot accumulates on the walls of the muffler. In this case, it will be necessary to purge the element with compressed air from the cylinder.
After performing all of the above procedures, you need to assemble the tool, and start it. Before using the saw, it needs to be given a few minutes to warm up the engine. Then you can continue to use the tool in normal mode.
