10 Clutch Adjustment
NOTICE
•
The friction clutch is NOT intended to protect people. It is designed to protect the operator and door
system against potential damage.
•
The friction clutch is factory adjusted during final testing. Proper adjustments should be done on site
according to the door characteristics and application.
•
In order to avoid the door from getting damaged when the lock is on, the friction clutch must be properly
adjusted according to the instructions below.
Best Practices Encouraged by Manaras-Opera
Manaras-Opera recommends the installation of a hard stop at the end of the tracks
(ex. bolt, deformation of tracks, bumper spring, pusher spring, etc). With such installation,
the door is prevented from running out of the tracks. The clutch (torque limiter) will
prevent any damage to occur to the door system.
To adjust the clutch:
1. Unlock the jam nuts with two (2) 15/16” keys, refer to Figure 40.
2. Rotate the nut counter-clockwise to release the tension.
3. Gradually rotate the nut clockwise until there is just enough tension to permit smooth operation (while still
allowing the clutch to slip if the door is obstructed).
4. Lock the jam nuts.
