Maintenance (continued)
Adjust the Drive belt
1.
Remove the drive belt housing cover (1).
2.
Loosen the 3 screws (2) allowing the pulley to slip and the drive belt (3) to loosen. The drive
belt should be seated correctly in the motor pulley and the drive pulley.
3.
Adjust the tension of the belt by putting a slotted screwdriver in the bracing slot (4). Pushing up
on the screwdriver will tighten the tension of the belt between the pulleys.
4.
Tighten all 3 screws (2).
5.
Test belt tension by squeezing both sides of the belt. If properly adjusted, the belt should "give"
between 1/8–1/4 inch (3–6 mm). Make sure that the belt teeth are properly seated in the pulley
gears.
6.
Carefully reinstall the drive belt housing cover (1), insert and tighten screw.
Note:
Excessive tightness on the pulley belt will cause increased noise and motor overload.
Premature failure will occur if belt is too loose.
