drIve Belt tensIon and alIgnment
Proper drive belt tension is important for prolonging the life of the drive belt and maintaining the superior
performance of the operator. To check the drive belt tension, take the following steps:
1. Remove the Front Access Panel.
2. Turn off the AC and DC power switches.
3. Remove the StrongArmPark DC top cover and drive belt cover.
4. Check to make sure the pulleys are aligned vertically.
5. With your nger, apply light outward pressure
to
the drive belt. If it is properly tensioned, it
should only move about 1/16 to 1/8-inch (1.6 to
3.2cm).
6. To replace or re-tension the drive belt. Loosen
the four motor bracket nuts and move the
motor accordingly.
7. Retighten the motor bracket nuts.
8. Replace the drive belt cover and top cover.
9. Turn the AC and DC power switches ON. This
cycles power which allows the operator to
search for the target magnet and “relearn” its
limits.
NOTE: Be aware that the arm will cycle open,
and then close, as it relearns its limits. If you don’t cycle
the power, the operator will not “relearn” its limits and
will not operate properly.
