5. Maintenance
Changing the Trimmer Line & Spool (0.065")
Over time, the trimmer line will wear down and need replacement. Follow these steps to change the line and spool:
- Ensure the trimmer is turned off and the battery is removed for safety.
- Locate the spool cap on the trimmer head and remove it.
- Remove the old spool.
- Take a new 0.065" nylon trimmer line. Insert one end of the line into the line insertion hole on the spool.
- Follow the arrow direction on the spool to wrap the line onto the spool in neat, straight rows. Leave about 15cm of line unwound.
- Insert the wound spool back into the trimmer head, ensuring the line is fed through the eyelet.
- Replace the spool cap, ensuring it clicks securely into place.
- Pull the line out past the line cutter about 15cm.
- Adjust the trimmer head to make sure the spool is horizontal parallel to the grass.

6. Troubleshooting
- Trimmer not starting: Ensure the battery is fully charged and properly inserted. Check that the lock-off button is pressed before engaging the trigger.
- Line not feeding automatically: Check if the spool is correctly installed and the line is not tangled or jammed. Ensure the line is the correct 0.065" diameter.
- Reduced cutting performance: The trimmer line may be too short or worn. Replace the spool with new line as described in the Maintenance section.
- Battery life is short: Ensure the battery is fully charged before use. Operating in very thick or wet grass can drain the battery faster. Consider having a spare battery for larger tasks.
