3. Setup
3.1. Battery Charging:
Before first use, fully charge both 21V Li-ion batteries. Connect the charger to a power outlet and then plug the charger cable into the battery. The indicator light on the charger will show charging status. Ensure batteries are fully charged before operation for optimal performance.
3.2. Chain Installation and Tensioning:
The chainsaw features a tool-less chain adjustment system. To install or adjust the chain, loosen the knob on the side cover. Position the chain correctly around the guide bar, ensuring the cutting teeth face the correct direction. Adjust the tension by turning the roller dial until the chain is snug but can still be moved by hand. Finally, tighten the knob to secure the chain and guide bar.
3.3. Oiling the Chain:
The chainsaw is equipped with a manual oiling system. Fill the provided oil bottle with appropriate bar and chain oil (not included). Locate the oil filling port on the chainsaw and add oil. During operation, periodically press the pump button to lubricate the chain and guide bar, ensuring smooth performance and prolonging chain life.
4. Operating Instructions
4.1. Starting the Chainsaw:
Insert a charged battery into the chainsaw handle. To start the chainsaw, press and hold the safety lock button located on the side of the handle, then simultaneously press the trigger. Release the trigger to stop the chainsaw.
4.2. Cutting Technique:
For optimal cutting performance and safety, hold the chainsaw firmly with both hands (if possible for larger cuts) or one hand for smaller, lighter tasks. Allow the chain to reach full speed before engaging with the material. Apply steady, moderate pressure. Avoid forcing the chainsaw through the material, as this can lead to kickback or damage to the tool.
When cutting branches, ensure the branch is stable and supported. Cut from the top down for smaller branches and use proper undercutting techniques for larger ones to prevent pinching the guide bar.

5. Maintenance
5.1. Chain Lubrication:
Regular lubrication is essential for chain and guide bar longevity. Continuously monitor the oil level and pump the oil button as needed during operation. A dry chain can lead to increased friction, overheating, and premature wear.
5.2. Chain Tension:
Check chain tension frequently, especially during initial use and after extended periods of cutting. A properly tensioned chain should be snug against the guide bar but still allow for manual movement. Adjust as described in the Setup section.
5.3. Cleaning and Storage:
After each use, remove the battery and thoroughly clean the chainsaw. Remove sawdust and debris from the chain, guide bar, and motor vents. Store the chainsaw in its original case in a dry, secure location, away from direct sunlight and extreme temperatures.
5.4. Battery Care:
Store batteries in a cool, dry place. Avoid fully discharging batteries before recharging. For long-term storage, charge batteries to approximately 50% capacity. Do not expose batteries to extreme heat or cold.
