e want to thank George H. Corbert,<br />
product manager of Arriflex Co. of<br />
America, Woodside,<br />
N.Y., for supplying<br />
us data pertinent to<br />
the company's Bauer<br />
theatre projector systems.<br />
While the particular<br />
data covered<br />
the Bauer U-3 35/<br />
70mm projector, the<br />
U-4 35mm model is<br />
very similar. For example,<br />
Wesley Trout<br />
adjustment<br />
procedures for the<br />
film path, projector head, optical sound<br />
unit and Iamphouse are applicable to both<br />
projectors.<br />
As a functional examination, check the<br />
oil level in the window at the rear of the<br />
projector mechanism. During standstill,<br />
the<br />
oil inspection window must show a filling<br />
of three-fourths. The oil level must never<br />
reach the top edge of the oil level indicator<br />
window. Remember to use only the very<br />
finest projector oil for maximum operation<br />
efficiency and longer wear of moving parts.<br />
Periodically examine all the sprockets<br />
for teeth wear. Worn sprockets not only<br />
can cause picture jump but also can damage<br />
film. Sprockets should be cleaned every<br />
day with a stiff-bristle tooth brush moistened<br />
with a little cleaning solvent.<br />
Check the idle rollers that hold the film<br />
on the takeup and feed sprockets to see that<br />
they run smoothly and are clean. Make sure<br />
all rollers turn freely so that they will not<br />

develop flat spots. Adjust the rollers so tbl<br />
the distance between them and the sproclfl<br />
face is equivalent to the thickness of t|<br />
pieces<br />
of film.<br />
There must be no play in the focusul<br />
mechanism for all three film formats. ApplJ<br />
some lubricant, such as Vaseline, to<br />
shaft of the lens turret.<br />
Be sure to check the drive belt for<br />
proper tension and alignment, also notin<br />
that it is in good condition and operate|<br />
smoothly.<br />
Rotate the sound drum on the opticd<br />
sound unit to make sure it runs smoothll<br />
and does not have any binds. This is eij<br />
tremely important for good sound reprodud<br />
tion. Keep this unit clean and free of an|<br />
dirt or dust.<br />
Another check is the alignment of<br />
rollers in the optical sound system. Makj<br />
sure they run freely.<br />
We recommend that you clean the prd<br />
jection lens and the sound optic every daj<br />
with a small brush, wiping clean with led<br />
tissue. Clean the condenser lens in the led<br />
holder. Remove the solar cell from tlj<br />
optical sound unit and wipe clean once<br />
awhile.<br />
Note: When replacing the solar cell,<br />
push it in firmly to the end stop.<br />
Occasionally check the functioning of tl<br />
braking roller in front of the optical soun<br />
unit. The proper adjustment of the brakir<br />
roller and the guide rollers of the sour<br />
unit is ensured when the compensatir<br />
roller on the sound drum remains more <<br />
