The lubricants mentioned in the text are:
Grease = Isoflex Topas L32
Oil = Isoflex PDP 48
Install the winding knob V-2206 and tension the
auxiliary shutter spring (30384) by releasing the pawl
(20919). Turn the knob clockwise and tension the
spring two turns at this time. Test the camera’s
function.
If the spring is too tight the pressure can be reduced by
operation of the shutter mechanism and then pressing
the signal arm down.
Fig. 28.
Note! Always check that the auxiliary shutter is closed
before turning the winding knob, otherwise there is a
risk that the top flap of the shutter will be damaged
when the mirror moves downwards.
Temporarily adjust the key position by loosening the
screws and moving the bearing bracket (13171) forward
until the key position is aligned to the red index dot on
the front plate. If the adjustment is insufficient
disengage the cogs between the front gear wheel and the
gear wheel (13167). Hold the gear by hand during this
operation so that the drive spring tension is not lost.
Fig. 29.
Loosen the front plate just sufficiently to ensure that the
mesh of the teeth is removed and turn the gear one
tooth at a time.
Retighten the screws.
The camera body should now function normally, i.e.
shutter release and winding on can be carried out in the
normal manner.
