Belts
•
Occasionally check the belt for wear. A worn belt should be replaced.
Belt Adjustment
During the first few hours of operation all belts go through a "break-in period" after which the belts
may need to be adjusted using the following instructions. Indications that the belts need to be
adjusted include:
•
Loss of power at the trimming head causing the head to spin unusually slow or stop.
•
Excessive wear on belt due to slipping.
•
The belt used to engage/disengage the trimmer head can be adjusted using the following
instructions:
1. Locate the thumb wheel adjuster on the control cable
2. Release control bail to disengage trimmer head.
3. Rotate thumb wheel a few turns counterclockwise
4. Re-engage trimmer head.
5. If trimmer head has not returned to normal operation, repeat steps 2-4.
Important!
Do not over tighten cable adjuster. This may cause the cable to break.
Excessive force should NOT be required to fully engage control bail.
