Replacing Projection Lamp
and Cleaning Lens
WARNING:
High-wattage projection lamps
get very hot in use. Be sure to allow ample
time for cooling before you handle them.
Cooling can be accelerated by turning off
the lamp switch and leaving the fan switch
on after you have moved the master con
trol lever to OFF. When the bulb has
cooled sufficiently, turn off the fan switch
and
disconnect the power cord before re
moving the lamphouse cover.
Loosen the lamphouse cover screw
(Figure 11), and lift off the cover.

To insert the new lamp, reverse the
procedure given above, being careful
to fit the lower lip of the lamp reflec
tor inside the two lamp

Caution:
Use extreme care when handling
the new lamp. Neither the quartz arc tube
nor the interior reflector coating should
be touched. Fingerprints or other deposits
can cause shortened life, premature reduc
tion in light output, or uneven illumination.
The lamp mount controls the posi
tioning of the lamp and is adjusted at
the factory for maximum evenness of
illumination. Readjustment should
not be necessary. However, if adjust
ment appears to be needed, loosen the

cleaned at frequent intervals. Because
of the rapid stop-and-go motion of the
film, particles of the emulsion lubri

edges of the fi l m and lodged on the

Use care in removing or replacing
the gate; force is not necessary.
To avoid the possibility of scratch
ing the gate, the pulldown claw should
be retracted before the gate is re
moved. Retract the claw by turning
the trial thread knob until the white
line is toward you. Remove the projec
tion lens.
Open the gate and insert a clean
or piece of paper to protect the
