2. Shutter does not engage (Shutter flap 350.04 U 5 runs closed) [i.e. second part of shutter
does not catch and runs with mirror]
Dismantle camera, as under Disassembly of Camera A.1 - A.4, or AA.1 - AA.3, and do as
described in Elimination of certain faults C.1 - Shutter flap falls back.
a) Verify the functioning of all the shutter levers together (i.e. levers must slide well and mirror
retaining spring must rest against the release lever 350.04-8). If Point a) is ensured, without
the fault being rectified, the shutter must be adjusted and/or readjusted.
b) Set the timing lever 350.04 U 3 (EXA) or 350.21 U 3 (EXAI/63) to B. Cock the shutter.
c) Restraining the first shutter flap with a finger, fire the shutter and let the first shutter flap run
slowly. Do not grasp the mirror. The release of the first shutter flap must occur about 2mm
before the shutter release lever stop. The release point is varied by the bend at the
adjustment slot in the shutter release lever.
d) Allowing the shutter release lever to move slowly outwards, the release of the second part of
the shutter flap must occur about 2mm before the edge of the plate [the plate above?]. The
release point is adjusted by bending the release nose of the shutter release lever [the lower
end].
e) Cock the shutter.
f) Release the shutter and pay attention to the second shutter flap. This must move in the
direction of the first shutter flap by about one millimetre before being stopped by release
lever 350.04-12 [the one at the bottom corner]. If this does not occur, the release lever must
be corrected [gerichtet] [i.e. bend the part turned inwards?].
g) Set the exposure time lever to 1/50 sec or 1/60 sec. Cock the shutter.
h) Holding the first shutter flap with a finger, fire the shutter and let the first shutter flap run
slowly, the release pin for the first shutter flap (see Fig.3) must now run towards the point
on the secondary lever on the exposure time lever. If this does not occur, the Anschlag
[?tab/stop?] on the secondary lever must be adjusted.
