5.2 Mini Chainsaw Assembly (if not pre-assembled)
If your mini chainsaw unit is not pre-assembled, follow the instructions in the separate assembly guide for attaching the guide bar and chain. Ensure the chain is correctly oriented and tensioned.
5.3 Pole Saw Assembly and Attachment
- To attach the mini chainsaw unit to the telescopic pole, align the connection points and secure it using the buckle/hook mechanism.
- Ensure the connection is firm and there is no wobble.
- To extend the pole, release the Extension Pole Clamping Lever (06) and Telescopic Buckle (05), pull the pole to the desired length, and then securely fasten both mechanisms.

6. Operating Instructions
6.1 Starting and Stopping the Tool
- To start: Press and hold the Safety Switch (04), then squeeze the trigger.
- To stop: Release the trigger. The chain will stop immediately.
6.2 Using as a Mini Chainsaw
For cutting smaller branches or logs at ground level, use the mini chainsaw unit independently. Ensure a firm two-hand grip and maintain a stable stance.

6.3 Using as a Pole Saw
For reaching high branches, attach the mini chainsaw unit to the telescopic pole. The pole extends up to 2 meters, providing a maximum reach of 4.8 meters (approximately 15.8 feet).
- Adjusting Pole Length: Use the Extension Pole Clamping Lever (06) and Telescopic Buckle (05) to adjust the pole to the desired length. Ensure both are securely tightened before operation.
- Adjusting Cutting Angle: Press the Angle Switch Button (03) to adjust the cutting head to angles of 0°, ±30°, ±60°, or ±90° for precise cuts from various positions.

6.4 Cutting Techniques
- Always start the chainsaw before contacting the material to be cut.
- Allow the chain to reach full speed before beginning a cut.
- Apply light, steady pressure. Do not force the tool.
- Be aware of kickback. Avoid cutting with the tip of the guide bar.
- When cutting branches, make an undercut first to prevent bark stripping.

7. Maintenance
Regular maintenance ensures the longevity and safe operation of your tool.
- Chain Lubrication: Always ensure the oil reservoir is filled with chain oil before and during use. The automatic lubrication system requires a constant supply.
- Chain Tension: Check chain tension regularly. A properly tensioned chain should be snug against the guide bar but still allow you to pull it around by hand.
- Chain Sharpening/Replacement: A dull chain will cut poorly and increase strain on the motor. Sharpen the chain as needed or replace it with a new one when worn. Refer to the guide bar for chain specifications.
- Cleaning: After each use, remove the battery and clean the tool. Use the provided brush to remove sawdust, debris, and resin from the guide bar, chain, and motor housing.
- Storage: Store the tool in a dry, secure place, out of reach of children. Remove batteries before long-term storage.
8. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not start | Battery not installed correctly or discharged; Safety switch not engaged; Tool malfunction. | Ensure battery is fully charged and properly inserted. Press safety switch and trigger simultaneously. If problem persists, contact support. |
| Poor cutting performance | Dull chain; Incorrect chain tension; Insufficient lubrication; Chain installed backward. | Sharpen or replace chain. Adjust chain tension. Refill oil reservoir. Check chain direction. |
| Chain stops during cut | Overload protection activated; Battery low. | Reduce cutting pressure. Allow motor to cool. Recharge or replace battery. |
| Oil leakage | Normal after use (residual oil); Loose oil cap; Damaged reservoir. | Store tool properly. Ensure oil cap is tight. If leakage is excessive, contact support. |
| Pole assembly issue (e.g., parts misaligned) | Incorrect assembly of pole sections. | Disassemble and reassemble pole sections carefully, ensuring all parts are correctly oriented and secured. |
