Note:
For the modified spring spindle version, additionally the lock-spring 370.03-52 on the
shutter-plate (right) and the two spring-spindle lock-wheels 370.03-51 (right-hand thread)
must be removed.
d) Mark the mesh of the old cocking lever with the intermediate wheel 370.07-19 and the
wheel to the cam-disc 370.07 U6 (see Fig 3).
e) Fit the new cocking segment in the marked position. Possibly the cam-disc must
subsequently be reset by one tooth.
f) Reattach the shutter-plate to the mechanism (pay attention to the rivet at the bottom of the
mirror 370.03 U13 [fits in the slot in the cocking lever]) , and screw the shutter cover-plate
back in position.
Note:
For the modified spring spindle version, screw the locking wheels 370.03-51 (right hand
thread) on to the spring-spindles, fit the lock-spring 370.03-52, and tension the spring-
spindles as described in C. 3. m) – Curtains Unserviceable.
g) Bring the curtain-rods to the marked positions (see also Figs. 7, 9, and 10) and fit and screw
down the pinions (as marked) (beforehand turn the shutter-wheels 370.07 U7 and 370.07 U8
towards the left to the firm stop, thereby unlatching the shutter release lever 370.07-11).
h) Cock the shutter. The mirror must go 1mm past the mirror catch lever 370.06 U6. For the
mirror to catch, it may be necessary to bend the adjustment lobe on the cocking segment
(see Fig 4). If necessary reset cam-disc 370.06 U6 such that the shutter release lever [the
catch for the lower shutter wheel] catches when the shutter is tensioned (see Fig. 5).
