MAINTENANCE
Lubrication
It is important that the projector be properly
lubricated. Refer to the "LUBRICATION CHART".
Lamp Adjustment on "Senior" Model
Refer to figure 5 for location of the LAMP
ADJUSTMENT screw on the "Senior" model. When-
ever a new lamp is installed the screen illumination
should be checked, without film in the picture gate,
for uniform distribution of light on the screen. To
make the adjustment turn the LAMP ADJUSTMENT
screw to the right or left as required, until the
screen is lighted uniformly.
Cleaning
If the equipment is to give consistently good
performance, it must be kept clean at all times.
Dust, oil, particles of emulsion, and all other dirt
should be removed. To clean the equipment proceed
as follows:

1. Cleaning fenses and reflector. Clean all
optical surfaces before use each time the equipment
is put into service. This may be done by gently
wiping them with lens tissue. If necessary, breathe
on the lens before the tissue is applied. When more
thorough cleaning is required, consult your dealer
for a good lens cleaner. Do not use carbon tetra-
chloride or alcohol on the lenses. After lens clean-
er has been used, gently wipe dry with lens tissue.
The following points need attention:
a. The condenser lens (figures 5 and 6).
To remove the condenser lens, pull out on the
latch and withdraw the lens assembly from its
mounting with the left hand. Clean and replace the
lens, taking care not to touch the lens surface
with the fingers.
b. The reflector, which is opposite the con-
denser lens in the lamp house, can be cleaned in
place.
c. The projection lens (figure 1). To remove
this lens, loosen the lens lock and pull the lens
out of the picture gate. Clean and replace the lens.
