Before using a chain saw, it is necessary to check the integrity of the equipment, the sharpness and tightness of the chain, to ensure that the equipment is in good working condition. At the same time, it is important to check whether the power or fuel of the chainsaw is sufficient to avoid affecting work efficiency due to insufficient power. Using a chain chainsaw requires certain operational skills and experience. Before use, it is recommended to read the device manual to understand the operating methods and precautions of the device. In practical operation, it is necessary to follow the correct operating procedures, maintain a stable posture and angle, and avoid safety accidents caused by operational errors.

Chain chainsaw, also known as chainsaw or power saw, is a mechanical device that uses an internal combustion engine or an electric motor as the power to cut through high-speed circular motion of the driving chain. It has the characteristics of fast cutting speed, simple operation, and wide applicability, and is widely used in fields such as logging, pruning, and building demolition.
