FIG. 1

Clutch Adjustment:

The GCL-MJ & MH operators have a friction-style clutch that needs to be adjusted.
NOTE: The clutch is intended to provide protection for the door, the operator and associated equipment. It is not
intended for entrapment protection. Therefore, the adjustment of the clutch should be such that the door and
operator function in this manner.
To Adjust the Clutch:
1. Decrease the tension on the clutch until the operator will not lift the door. Turn the adjusting castle nut
counter-clockwise to decrease clutch tension and clockwise to increase clutch tension.
2. After completing step 1, begin to increase tension on the clutch until the operator is capable of lifting
the door through the complete cycle without clutch slippage.
3. Finally, insert the cotter pin through the castle nut and shaft
and bend the outer leg of the cotter pin.
NOTE: Periodically check the system for proper clutch action. If
clutch starts to slip after working properly for some time, check
manual operation of door BEFORE adjusting clutch. The door
may not be operating freely or the counterbalance spring may
need adjusting. Repairs and adjustments must be performed by a
trained service representative using proper tools and instructions.
