Replacing/Adjusting the Motor Drive Belt
To replace or adjust the motor drive belt:
1.
Drain the water out of the bath.
2.
Turn off the power and remove the power cord.
3.
Lay the unit on its left side, using a soft pad to protect the finish.
4.
Remove the bottom cover using a Phillips (+) screwdriver. Retain the screws for
reuse.
5.
Rotate the large pulley (
see Figure 9 below
) and exert a light pressure to the belt
so the belt feeds out of the pulley groove.
Figure 9: Belt Replacement & Adjustment
6.
Install a new belt by feeding it onto the motor pulley and guiding it onto the large
pulley while rotating the large pulley.
7.
Check the belt tension with a light side pressure near the center of the belt. It
should deflect approximately ¼ inch (6.4 mm). If adjustment is needed, loosen the
two bolts holding the motor plate and move the plate to either loosen or tighten the
belt. Tighten the bolts when the adjustment is correct.
8.
Replace the bottom cover, tightening the Phillips head screws.
9.
Connect the power cord.
10.
Set the circuit breaker to the “ON” position.
The unit is ready for operation.
CAUTION!
Be sure to keep fingers clear to avoid pinching them
between the belt and pulley.
