Setup

- Connect the power adapter to a standard wall socket.
- Insert the round plug from the power adapter into the charging port on the battery.

The chainsaw comes pre-assembled, but you may need to adjust the chain or replace it. Always ensure the battery is removed before performing any installation or adjustment.
- Step 1: Install the guide plate and chain onto the chainsaw unit. Pay close attention to the direction of the chain teeth to ensure correct operation.
- Step 2: Attach the side panel cover over the guide plate and chain.
- Step 3: Insert the nut but do not tighten it completely yet.
- Step 4: Use the included screwdriver to adjust the chain tightness. Ensure there is only a 0.3cm gap between the chain and the guide bar.
- Step 5: Tighten the nut securely with the provided wrench.
- Step 6: Check the tension of the saw chain. For correct tension, 1-3 saw teeth should be exposed when pulling the chain by hand.
- Step 7: Once the chain is properly installed and tensioned, slide a charged battery into the chainsaw unit until it clicks into place.
