Installation and adjustment of the door operator is best accomplished from an upper landing. Place
the car top at a comfortable working height, and use the landing as a working platform.

2. Remove the door operator from the shipping carton and crate. Locate and store the bag of
parts.
3. Remove the cover from the rear of the operator by loosening the two top screws and the two
lower rear screws.
4. Inspect the wiring. Make sure all connections are secure.
5. Loosen the bolts holding the mechanical stops.
6. While observing the shaft containing the cams (inside the operator), rotate the drive wheel.
7. Check and adjust, as necessary, the tension of the 3 V belts between the drive wheel and the
jack shaft sheave. See Figure 2 on page 9.
a. Loosen the two bolts on the idler arm, and turn the locknut on the adjustment screw
