Elevation Drive
Step 1
Step 2
Step 3
With the azimuth orientation of the antenna correctly oriented for stowing, locate the
brake cover on the elevation drive motor, (the same size and type of motor is used for
both elevation and azimuth drives) and follow the same procedure required for azimuth
brake release.
CAUTION!
When Elevation Brake is Released, Feed Boom/Reflector Will Be Unrestricted. At
Extremely High Look Angles the Feed Boom/Reflector May Need to be Guided in
the Pproper Direction by a Second Person. As the Feed Boom Approaches a
Horizontal Position Care Must be Taken During Manual Brake Release as the
Stowing Boom Will Pass Through the Access Area to the Brake. Coordinating
With a Second Person Assisting/Guiding Reflector to Stow Position, Brake
Release Operator Will Need to Work Carefully Around Closing Reflector Assembly,
Avoiding Scissor Action of Closing Assembly.
Release the brake and carefully lower the reflector/boom assembly into stowed position.
Install brake cover with nylon washers and wing nuts (orientation of drain/weep hole in
brake cover should be near the 6 o'clock position).
