General Chainsaw Safety

• Keep all parts of the body away from the saw chain when the chainsaw is operating.
• Always hold the chainsaw firmly with both hands.
• Ensure the work area is clear of other persons, children, and pets.
• Do not operate a chainsaw when you are tired, ill, or under the influence of drugs or alcohol.

Starting the Chainsaw

1. Ensure the battery is fully charged and properly installed.
2. Hold the chainsaw firmly with both hands, maintaining a balanced stance.
3. Press the lock-off button (safety switch) with your thumb.
4. Squeeze the trigger to start the saw chain. Release the lock-off button once the chain starts moving.

Cutting Techniques

• Always ensure the saw chain is at full speed before making contact with the wood.
• Use the low-kickback bar and chain for smooth and controlled cuts.
• For branches, support the branch to prevent pinching the saw chain.
• When cutting logs, ensure they are stable and cannot roll.
• Periodically press the oil prime button during extended cutting to maintain lubrication.

5. Maintenance

General Maintenance

• Always remove the battery pack before performing any maintenance.
• Keep the chainsaw clean and free of debris. Use a brush or compressed air to remove sawdust from the motor housing and chain area.
• Regularly check the chain tension and adjust as needed.
• Ensure the bar and chain oil reservoir is always filled with appropriate oil.

Chain Sharpening

The saw chain will eventually become dull with use. A dull chain will not cut efficiently and can cause excessive wear on the chainsaw. Sharpen the chain using a 4.5 mm round file. It is recommended to use a file guide to maintain correct angles.
