Refer to the engine service manual provided with this unit.
Belts
•
Occasionally check the belts 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 between the trimmer head and the double idler pulley has an automatic belt tightener
that automatically adjusts when the head is tilted. If you do not regularly tilt the head on your
trimmer, it is recommended that you loosen the head twice a year (see Edge Trimming).
•
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
(see illustration)
.
2.
Release control bail to disengage trimmer head.
3.
Rotate thumb wheel a few turns counterclockwise
(from normal operating position).
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.
Make sure your trimmer is in safe working condition by keeping the following guidelines in mind every time you
