and withdrawing the aperture holder without
twisting or tilting it. To install it, simply
follow the reverse order.
Exchange the film gate by pressing the
latch and lifting it out together with the
pivoting shaft. When replacing it, watch
that the film gate is adjusted in accordance
with the intermittent
sprocket and the aperure
holder. Be sure to insert the pivoting
shaft before installing
the film gate.
Film Ciate Adjustment
The film gate can be adjusted only while
the film runs through the projector. It is
easier to adjust the gate by using a small
mirror to see how the film passes along the
Maltese cross intermittent sprocket. The
outer edges of the sprocket must be clearly
off the outer edges of the perforations. Adjust
the film gate by shifting it on the pivoting
shaft. For this purpose, loosen the socket
screw which retains the film gate on the
pivoting shaft. There is not much play for
adjustment, but little as it is, it nevertheless
will be sufficient for proper adjustment.
After adjusting the gate, be sure to tighten
the hexagon socket screw, otherwise the
film gate may be accidentally shifted laterally
during removal or installation.
When adjusting the guide rollers above
the film gate, the front half of the roller,
which serves as a stop for the film run,
must be adjusted in such a way that the
roller touches the film slightly. For this
purpose, loosen the set screw and shift the
whole shaft together with the roller. The
rear half of the guide roller must press the
film against the front half so that it touches
the shoulder of the front half. If the film
should buckle, reduce the spring pressure
of the leaf spring by means of the nut
there.
To exchange the felt rings in the takeup
bearing, loosen the sockethead screw and

There are a number of hints one rat
pursue to facilitate the search for the sour
of disturbing running noise in the project
head.
Remove the covers at the rear of t
projector mechanism and the support. Th
remove the V-shaped belt for the takei
friction.
Remove the toothed belt for the sup[
drive and the takeup sprocket and— in:
much as it is built in—take out the toofhl
belt for the drive of the magnetic soul
unit. If the disturbing noise is no lonjr
apparent, the source of the noise trouble,
to be found in the areas just cleared
the event the noise continues after siji
dismantling, the source of the noise trou
is located in the areas of the driving mot
the intermediate bearing, or in the Malt
cross arrangement.
Synchroflex
Belt
With regard to the Synchroflex belt, e
toothed belts must be adjusted with the d
of the intermediate bearing in such man:r
that they run smoothly and silently in c
middle of the Synchroflex wheels. To tijten
the toothed belts, adjust the eccenic
bearings in which the supply and takjp
shafts run. For this purpose, loosen \e
hexagon socket screw for the supply sift
within the projector mechanism. ie
mounting screw for the takeup shaft is
located at the front of the sound optal
unit. There is access from the outside.
The motor's toothed belt alignment atie
idling gear bearing is guaranteed by adjiting
the outer belt and the V-shaped lit.
