Adjustment of the release sequence
Make sure the winding knob V-2206 and the bayonet
plate tool 904644 are installed.
Release the camera and keep it released by holding the
release bar and push rod back.
Move the release bar and push rod to the front slowly
and observe the closing sequence.
Fig. 41.
1. Key releases to fully released position.
2. Auxiliary shutter closes. Note that the winding knob
is blocked all the time until the auxiliary shutter
closes.
3. The stop lever disengage giving clearance for the
winding knob.
The auxiliary shutter closing position can be adjusted by
bending the rear of the release arm (13357) which bears
on pin ”A” as shown.
Use the tool V-2203.
Check for free play between the release bar and signal
arm when the camera is fully released.
Fig. 42.
Note! The final sequence check is done when the
chassis is mounted in to the shell by using the
exposure gauge V-2354. (See page 5:11).
Check that the auxiliary shutter does not close
spontaneously when the camera is pre-released. Carry
out a number of operations of the release arm (13357).
If the auxiliary shutters do close using this test, adjust
the tongue on lever (22769) which stops the release arm
against the signal arm.
Check the lever does not jam between the release arm
and the signal arm when the camera is released.
Test by operating the shutter and letting the release bar
return slowly. Check that the lever has a small amount
of play during this movement.
