Operating Instructions
1. Starting the Chainsaw
- Ensure the chain brake is disengaged (pulled back towards the front handle).
- Grip the front handle with your left hand and the rear handle with your right hand.
- Press the trigger lockout button with your thumb, then squeeze the trigger to start the chain.
2. Cutting Techniques
Always maintain a firm grip with both hands. Position yourself securely and ensure the chain does not contact the ground or other obstacles. Use the wrap-around handle for comfortable cutting and user control in various positions.

- Limbing: Remove smaller branches from a fallen tree. Work from the bottom up, supporting the branch to prevent pinching.
- Bucking: Cut a fallen log into smaller sections. Be aware of potential kickback and pinching.
- Felling: For felling trees, consult professional guidance or extensive training. This chainsaw is primarily designed for limbing and bucking.
3. Stopping the Chainsaw

Maintenance
Regular maintenance ensures optimal performance and extends the life of your chainsaw.
- Chain Sharpening: A sharp chain is crucial for safe and efficient cutting. Sharpen the chain regularly or replace it when dull.
- Chain Tension: Check chain tension frequently. The chain should be snug against the guide bar but still able to be pulled freely by hand.
- Bar Lubrication: The automatic oiler provides continuous lubrication. Ensure the oil reservoir is always filled with appropriate bar and chain oil.
- Cleaning: After each use, clean sawdust and debris from the chainsaw, especially around the chain, guide bar, and motor housing.
- Storage: Store the chainsaw in a dry, secure location out of reach of children. Remove the battery before storage.
