CAUTION
Check the working condition of the door before installing the
operator. Door must be free from sticking and binding.
If the door is equipped with a latching device, secure the locking
bar in the open (unlocked) position. This style operator will act as a
latching device when the door is down and therefor the door’s
lock is no longer needed.
If the door lock is to remain functional, an interlock switch MUST
be installed which will prevent operation of the door whenever
the door lock is engaged. Refer to the Wiring Instructions, section
5.5, of this manual for proper connection of the interlock switch.
1) Measure the width of the door to determine the center. Make a
vertical line as shown in Fig. 7. (If the vertical line is not in line
with a door stile, a means of attaching the door bracket to the
door must be provided. This can be accomplished by spanning
the center of the door’s top section (between the top and
bottom rail) with a suitable material such as wood or steel.
NOTE: On torsion spring doors with an uneven number of panels, the
operator may be attached to the stile nearest to the center.
2) Prepare for attaching drawbar to header. If suitable woodwork is
not already in place, securely affix a 2" x 6" block of wood as
shown in Fig. 7.
3) Center the block on the header.
4) Mark the center vertical line on this block.
5) Use a level, as shown in Fig. 8 (pg 4.6) to find the highest point
of travel for the door.
6) Mark a horizontal line across the vertical line you made on
the header at 2-1/2" above the highest point of door travel.

These 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. They
have a motor reversing feature that is integrated with the clutch assembly. If an
obstruction is placed in the pathway of the door during operation the motor will
stop and reverse when the clutch begins to slip. Therefore, the adjustment of the clutch
should be such that the door and operator function in this manner. The clutch should be
such that the door and operator function in this steps for clutch adjustment follow:
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) Test the reversing feature of the operator by placing an obstruction under the
door during a close cycle. The door should reverse on the obstruction and return
to the open position. If the door does not close but comes down part way and
reverses without any obstructions in its path, then increase the clutch tension
until the door will close fully.
4) 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.
Clutch Adjustment
To Adjust the Brake
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.
