Remove and Reinstall the Bottom Dust Cover
The function of the bottom dust cover, which is not
present on all BH‐2 stands, is to prevent dust and debris
from entering the opening at the bottom of the arm
(where the arm attaches to the base casting) and
fouling the mechanism of the sliding focus block.
Although this dust cover, if present, does not need to be
removed to perform the maintenance described in this
document, its removal may be desirable to allow for a
more‐thorough cleaning of any dust and debris
accumulation in the area of the dust cover, and the
removal procedure is included in this document for the
sake of completeness.
Use a suitable JIS screwdriver to remove the two M2x4
screws securing the dust cover onto the bottom of the
arm casting (see
Figure
cover (see
Figure
22) and clean any dust and debris
from the cover and from the associated area of the arm
casting. Reposition the dust cover in place and secure it
to the arm casting with the two M2x4 screws.
