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 tension on the clutch until the operator will not lift
the door.
Turning the adjustment castle nut counter-clockwise will
decrease tension and clockwise will increase tension.
2) Gradually increase tension 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.
Brake Adjustment
1) Loosen the Adjustment Bracket Lock Nut/Bolt.
2) Slide the Adjustment Bracket as needed to reach the desired
spring tension.
When properly adjusted, the pivot arm should
move with very little effort.
3) Re-tighten the Adjustment Bracket Lock Nut/Bolt.
