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.
