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

cover (see

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.
