3. Setup and Assembly
3.1 Battery Charging
Before first use, fully charge both batteries. Insert the battery into the charger and plug the charger into a standard power outlet. The indicator light on the charger will show the charging status.
Figure 2: The included 21V 4.0Ah Lithium-Ion batteries and charger. Ensure batteries are fully charged before use for optimal performance.
3.2 Chain Installation (if required)
The chain may come pre-installed. If not, or if replacing the chain, follow these steps:
- Turn the green cover counter-clockwise to remove it, then take off the cover, guide bar, and old chain (if replacing).
- Push the pin to the RIGHT to lock it.
- Place the guide bar and new chain on the saw, ensuring the pin fits through the guide bar hole. Check the chain alignment.
- Press the guide plate near the pin, return the pin to its original position; the chain will self-tension.
- Reinstall the covers, ensuring everything is secure.
- Tighten the green cover clockwise UNTIL IT CAN'T TURN FURTHER.

3.3 Assembling the Pole Saw Configuration
To convert the mini chainsaw into a pole saw:
- Attach the chainsaw head to the extension pole. Ensure it clicks securely into place.
- Adjust the pole height to your desired working length. The pole is retractable and can extend to provide a maximum working length of approximately 15 feet (based on a 6ft person holding the pole at shoulder level).
- Insert a charged battery into the battery slot on the handle.

5. Maintenance
5.1 Chain Lubrication
The chainsaw features an auto lubrication system. Ensure the oil reservoir is filled with appropriate chainsaw bar and chain oil before each use. This system provides continuous lubrication for smooth cutting and extended chain life.
Figure 8: Demonstrating the auto oil system. Regularly check and refill the oil reservoir to ensure proper chain lubrication.
5.2 Chain Tension Adjustment
Proper chain tension is critical for safe and efficient operation. Check chain tension frequently, especially during initial use and after prolonged cutting.
- If loose, turn the cover counter-clockwise to slightly loosen (avoid over-loosening).
- Move the guide bar up/down to self-tension. If not tight, check "HOW TO INSTALL CHAIN" for proper positioning.
- Tighten the green cover clockwise UNTIL IT CAN'T TURN FURTHER. If the chain loosens quickly, it wasn't tightened properly.
Figure 9: Visual instructions for adjusting the chain tension. Correct tension prevents chain derailment and ensures optimal cutting performance.
5.3 Cleaning and Storage
- After each use, remove the battery and clean the tool of sawdust and debris.
- Use a soft brush or cloth. Do not use harsh chemicals.
- Store the tool in a dry, secure place, out of reach of children.
- Ensure the chain is covered with its protective sheath during storage.
