Chainsaw is short for "gasoline chainsaw" or "gasoline powered saw". Can be used for logging and crafting lumber. Its sawing mechanism is a saw chain. The power part is a gasoline engine. It is very convenient to carry and the operation is relatively simple.

Chainsaw operation steps:
1. First, start the chain saw, remember not to pull the starting rope to the end, otherwise the rope will be broken. When starting, pay attention to gently pull up the starting handle by hand, and when it reaches the stop position, pull it up quickly with force, and at the same time press down on the front handle. Also be careful not to let the starter handle bounce back freely, use your hand to control the speed and guide it slowly back into the casing so that the starter rope can be rolled up.
2. Secondly, after the engine has been running for a long time under the maximum throttle, let it idle for a period of time to cool the air flow and release most of the heat. Avoid thermal overloading of components on the engine causing combustion.
3. Again, if the engine power drops significantly, it may be because the inside of the air filter is too dirty. Take out the air filter and clean the dirt around it. If the filter is stuck by dirty things, you can put the filter in a special cleaner or wash it with cleaning solution and then dry it. After cleaning and installing the air filter, check that the components are in the correct position.
