Before use, you must carefully read the chain saw instruction manual to understand the characteristics, technical performance and precautions of the chain saw.

Fill the fuel tank and engine oil tank with enough fuel before use; adjust the tightness of the saw chain, not too loose or too tight.

Operators must wear work clothes, helmets, labor protection gloves, dust-proof glasses or face protection before operation.

After the engine is started, the operator holds the rear saw handle with his right hand and the front saw handle with his left hand. The angle between the machine and the ground cannot exceed 60°, but the angle should not be too small, otherwise it is difficult to operate.

When cutting, the lower branches should be saw first, and then the upper branches. The heavy or large branches should be cut in sections.
