i) Set the exposure time lever to 1/150 sec or 1/175 sec. Cock the shutter.
j) Holding the first shutter flap with a finger, fire the shutter and let the first shutter flap run
slowly. The release pin for the shutter flap (see Fig.4), must now release the second shutter
flap in the indicated position. If this does not occur, the trip lever 350.04-13 [the long
vertical lever] must be bent at its lower end.
k) Control of the release at all shutter speeds.
The release of the second shutter flap must occur as described in Point j) at all shutter
speeds. If readjustment at the 1/50 sec (or 1/60 sec) or 1/25 sec (or 1/30 sec) should still be
necessary, then this is to be made at the curve of the trip lever over the half-round recess.
l) Check the shutter with a shutter time measuring device.
Example 1:
Shutter too light: Reduce the tension of the first shutter flap, or increase the tension of the
second shutter flap. [HOW?????????????????????????????????]
Example 2:
Shutter too dark: Increase the tension of the first shutter flap, or reduce the tension of the
second shutter flap. [HOW?????????????????????????????????]
The options of the shutter time adjustment stated under l) are used alternatively by the
camera mechanic.
