Adjusting the Clutch (Optional)
NOTE: The clutch is intended to provide protection for the door,
operator and associated equipment. It is not intended for
entrapment protection.
The clutch does not require any disassembly to adjust.
1) All adjustments should be made in very small increments
(e.g. turning adjustment bolts 1/4 turn per increment).
2) When making adjustments, be sure to turn all 3 adjustment bolts
an equal amount. Fig 13.
— To increase tension, turn adjustment bolts clockwise.
— To decrease tension, turn adjustment bolts counter-clockwise.
3) Clutch needs to be adjusted to a tension just above what is
required to open and close door without clutch slippage.
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. Door may not be operating
freely or counter-balance spring may need adjusting. Repairs and
adjustments must be performed by a trained service representative
using proper tools and instructions.
