GENERAL MAINTENANCE
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 Kinec cover and protecon plate.
2� Turn o the DC and AC power switches.
3� Check to make sure the pulley is aligned horizontally.
4� With your nger, apply light outward pressure to the drive belt. If it is properly tensioned, it should
only move about 1/16-inch to 1/8-inch (1.6 to 3.2mm). See “Figure 50. Drive Belt Tension and
Alignment” on page 174�
5� To replace or re-tension the drive belt, loosen the two motor bracket bolts and move the bracket
accordingly.
6� Reghten the motor bracket nuts.
7� Replace the protecon plate and Kinec cover.
8� 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.
9� If you don’t cycle the power, the operator will not “relearn” its limits to operate properly.
Be aware that the gate will cycle open
and close (close or open) as it relearns
its limits. See “Reseng the OPEN
and CLOSE Limits” on page 99.
