Figure 7. Brake Release Procedure.

(azimuth gear motor shown, elevation gear motor similar)

When the brake is released, a black/red disk assembly (brake/clutch mechanism ) will begin to rotate as the motor free-wheels. This may be used as a visual sign that brake disengagement has been achieved.

Release the brake and rotate in azimuth to achieve azimuth stowing position. The end of the feed boom may be used as a push point for azimuth rotation (only during power loss).

Install the brake cover with the nylon washers and wing nuts.
