A solenoid brake is optional on all models, and is optional on 1/3 and 1/2 horsepower models. The brake is

adjusted at the factory and should not need additional adjustment for the the life of the friction pad.

Replace friction pads when necessary. Refer to the

illustration for identification of components for the

solenoid type brake system.

1. Remove cotterpin from nut on the clutch shaft.

2. Back off clutch nut until there is very little tension

on the clutch spring.

3. Tighten clutch nut gradually until there is just

enough tension to permit the operator to move the

door smoothly but to allow the clutch to slip if the door

is obstructed. When the clutch is properly adjusted, it

should generally be possible to stop the door by hand

during travel.

4. Reinstall Cotterpin.
