Belt Inspection and Tensioning
1. Retighten belt after the first 25 hours of use. To test the tension, follow the steps
below.
2. Remove belt cover.
3. Examine belt for cracks, tears in the backing, or other damage. Replace belt if dam-
aged according to the steps below:
A. Loosen the motor bracket bolts and slide the bracket up as far as possible.
B. Slide the old belt off of the larger pulley first, then remove it from the motor pul-
ley.
C. Put the new belt around the small pulley first, then around the large pulley.
D. Move the motor bracket down the belt until it is properly tensioned according to
the directions below. Tighten the motor bracket bolts.
4. Check and adjust belt tension according to the steps below:
A. Press on the centre of the longest span on the belt with moderate finger pressure.
Then measure the deflection distance, the distance that the belt moved. The belt
should deflect anywhere from 1.3cm (1/2”) to 1.9cm (3/4”).
B. If the belt deflects too much, tighten belt by loosening the motor mounting bolts
and moving the motor away from the other pulley slightly. Secure motor mounting
bolts and retest tension. If the belt is too long to be properly tensioned, it must be
replaced.
C. If the belt deflects too little, loosen the motor bracket bolts and lift it upwards.
Secure motor mounting bracket and retest tension.
Before use, replace belt motor cover.
