JH-DC OPERATOR INSTALLATION GUIDE
TORQUE LIMITER ADJUSTMENTS
Before adjusting the torque limiter, make sure the door is in good working condition. One person should be able to move the door
by hand. Torque limiters are set light at the factory and must be adjusted during installation. Adjust the torque limiter tight
enough to keep it from slipping during normal operation.
To adjust the torque limiter in the Model JH-DC:
1. Loosen the jam nut.
2. To increase the output , turn the adjustment nut clockwise one flat, or 1/6 turn, at a time until desired output is obtained.
To reduce the output , turn the adjustment nut counterclockwise one flat, or 1/6 turn, at a time until desired output is
obtained.
3. Tighten the jam nut against the adjustment nut when finished.
