3.17 Projection Assembly Removal
Caution —
The aperture wheel and ND wedges on the projection
assembly are delicate and easily damaged —
work carefully!
Any
fingerprints or contamination on the optical area of the film wedge may
necessitate replacement of the wedge; it cannot be cleaned, other than to
blow off any dust.
1)
Remove the front and rear covers (3.2, 3.3)
2)
Loosen the screw holding the finger guard/baffle plate just behind the film wedge
(Figure 3-5). Easiest access to the screw is through the hole in the film wedge.
