7.3 Removing the Side Cover

To remove the side cover, unscrew the screw on the side cover counterclockwise and then remove the cover.

7.4 Removing the Chain

The chain can be directly removed by first taking out the side cover, then removing the guide plate, and finally pulling the chain down.

8. Maintenance

8.1 Chain Tension Adjustment

There is a screw on the back of the guide plate/chain fixing plate to adjust the tightness of the chain. The chain can be tightened by turning clockwise and loosened by turning counter-clockwise with the equipped screwdriver.

Note: It is normal for the chain to be slightly loose. If it is too tight, it will affect work efficiency. The best adjustment standard is to pull the chain in the middle of the guide plate by hand to expose 1-3 middle guide teeth.

8.2 Lubrication

The chainsaw features an oil injection device. Regularly add lubricating oil to the fuel tank port to ensure smooth operation and prolong the life of the chain and guide bar. (Note: Lubricating oil is not included with the product).

• Store the chainsaw in its plastic box in a dry, secure place, out of reach of children.
