Your chainsaw comes with an 8-inch guide bar and chain pre-installed. To switch to the 6-inch setup:
- Ensure the battery is removed for safety.
- Loosen the side cover knob and remove the side cover.
- Carefully remove the pre-installed 8-inch guide bar and chain.
- Place the 6-inch chain around the drive sprocket and then align it with the groove of the 6-inch guide bar.
- Mount the guide bar and chain onto the chainsaw body, ensuring the chain tensioning pin fits into the hole on the guide bar.
- Replace the side cover and tighten the knob slightly.

3.3. Chain Tensioning
This model features tool-free chain tensioning for quick adjustments.
- With the side cover loosely attached, turn the chain tensioning knob clockwise to increase tension or counter-clockwise to decrease tension.
- The chain should be snug against the guide bar, but still able to be pulled freely by hand. There should be no excessive slack.
- Once tension is correct, fully tighten the side cover knob.

- Locate the oil reservoir cap on the chainsaw body.
- Unscrew the cap and fill the reservoir with appropriate chainsaw bar and chain oil (provided oil bottle can be used for filling).
- Replace the cap securely. The system will automatically lubricate the chain during operation.

4.1. Starting the Chainsaw
- Ensure the battery is securely installed and the chain is properly tensioned and lubricated.
- Grip the chainsaw firmly with both hands.
- Press and hold the safety lock button (usually located on the side of the handle).
- While holding the safety lock, press the trigger switch to start the chainsaw. Release the safety lock once the chainsaw is running.
4.2. Cutting Techniques
- Pruning Branches: For smaller branches, make a relief cut on the underside first to prevent bark stripping, then cut from the top.
- Cutting Logs: For logs up to 8 inches thick, ensure the log is stable. Begin cutting with the bottom of the guide bar, allowing the chain to pull itself into the wood.
- Avoid Kickback: Always be aware of the guide bar tip. Contact with the tip can cause kickback, leading to loss of control.
- Cutting Speed: The chainsaw offers a high cutting speed of 36.5 FT/S for efficient operation.
