Clutch Adjustment - Genie GCL-J&H Installation Manual

Clutch Adjustment Fig. 9
The Operators have a friction style clutch that can 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.
To Adjust the Clutch
1) Decrease the compression on the clutch until the operator will
not lift the door.
• Turning the adjustment castle nut counter-clockwise will
decrease compression and clockwise will increase compression.
2) Gradually increase compression until the operator will perform a
complete open and close cycle without clutch slippage.
3) Insert a cotter pin through the adjustment castle nut and bend a
leg of the cotter pin to hold it in place.
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.
