A. Cover Removal
1. Remove the upper and lower screws which
secure the cover to the main assembly. Do
not loosen the lower screws inside the cut
out slots in the bottom of the cover.

for threading into the plastic of the front and
rear panels. DO NOT use the finer threaded
lower screws for this.

turn the screw clockwise to tighten. Do not
over tighten.
