A chain saw is a hand saw powered by a gasoline engine. Its main purpose is to log and make timber. Its task principle is to stop the cutting action by the transverse movement of the intertwined L-shaped blades on the saw chain. Chain saws also play a big role in our daily lives. In the past, we were able to harvest trees manually, but since we have chain saws, as long as there is oil, we can save a lot of effort, which is also a lot more convenient. Therefore, chain saws have generally been favored by people as soon as they went on the market. But sometimes chain saws also present a lot of problems, and some people are very confused about what is going on with chain saw weakness? Let's analyze in detail the chain saw weakness.

First,analysis of the reasons for the inability of the chain saw
1. The air filter of the chain saw can filter foreign matter such as saw dust and dust to prevent foreign matter from entering the cylinder and causing severe accidents of cylinder pulling. When the chain saw shows faults such as refueling and stalling, weak tasks, overheating of the initiator, etc., it may be that the air filter is dirty and needs maintenance. The air filter should be introspected in the task line. The clean and qualified air filter should be inspected thoroughly and brightly under the sunlight. The unqualified air filter is covered with wood residue and dust, and it feels thick and hard to touch. At this time, use hot soapy water to clean , Dry, clean, light-transmitting, and soft air filter can ensure the normal task of the chain saw.
2. The igniter is not good, the cylinder body is worn too much, the steam and oil ratio is not correct, the filter outside the fuel tank is blocked, and the crankshaft bearing case seal will cause the machine to be weak. The main reason is that there are many shortcomings of the air filter carburetor.

Second, the chain saw is unable to solve the problem
1. The chain is blunt, change a chain.
2. If the spark plug is old, just replace it with a spark plug.
3. The gap between the cylinder and the piston is large, adjust the gap after assembly.
4. The oil ratio of the mixed oil is higher, and the oil percentage is reduced.
5. The high pressure package is not suitable, please change to a suitable one.
6. The carburetor has three adjusting screws, which are distinguished as T, H, L; clockwise means tight, reverse time means loose; T: idle speed screw, tighten, the oil will enter more, loose, the oil will be less. H high-speed screw, the function is to run the chain saw at high speed, tighten the chain saw will run fast, loose it slow L low-speed screw, the function is to adjust the low speed of the chain saw, the chain saw will turn fast when it is tightened, and it will turn slowly when loosened, or it will not turn, or it will die.

How to adjust the chain saw weakness
Although the chain saw is easy to use, no one is perfect, and the same is true for tools. When you use it for a long time, the chain saw will also have many problems, not only the problem of the chain saw’s weakness, but what we can do is Pay attention to the above points when using it, and also pay attention to maintaining the chain saw. If there is a problem, you can get a special *12* repair chain saw to stop the repair. These are the best solutions. What we have to do is to deal with the problem as soon as it presents it.
