Before reattaching the cover, the drive arm window must be
removed from the side of the cover (Figure 7). Either use a utility knife
to cut the window from the cover, or use a punch and a small hammer
to carefully punch out the window. Once the window is removed,
use a small file to remove any burrs that remain. Make certain that all
pieces and/or particles are cleaned up and removed before proceeding.
