equipment. It is not intended for entrapment protection.
To Adjust the Clutch: Figure 32
• 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.
• Gradually increase compression until the operator will perform a complete open and close cycle
without clutch slippage.
• 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
