REPLACING FUSE
Failure of the exciter lamp to light may indicate trouble
in the ornplifler system or that the fuse is blown. To replace
the fuse, located on the bottom of the Kodascope, dis-
connect the power cord, unscrew the
FUSE CAP,
and pull
the fuse from the cap. Insert a new fuse (3 amperes,
250 volts, part No. 78464) into the cap and replace the
cap on the machine.
If
the exciter -lamp still fails to light,
the oscillator tube (the second tube from the right-hand
end) may need replacing.
The Sound Kodascope FS-10-N is designed for use with
alternating current only. If the projector is connected to
direct current, the fuse will blow. See page XIV for
servicing helps.
R~PLACING
BELTS
Remove the four
SCREWS
from the forward cover. When
replacing the upper spring belt, push the rewind lever
in
so that the upper pulley will turn freely. Feed the belt
through the opening in the front of the Kodascope and
between the two
BELT GUiDES
and the pulley. To replace
the lower spring belt, pull the rewind lever
out
and pro-
ceed as described above.
To replace the
DRIVE BELT,
the threading knob must be
removed and it is more convenient if the flywheel is also
removed. To remove the threading knob, loosen the two
opposite screws in the hub of the threading knob. Raise
the Kodascope with the elevating screw until the flywheel
clears the extended glider post; then remove the smaller
nut holding the flywheel. Hold the sound drum while turn-
ing this nut. Place the new belt around the pulleys; then
replace the flywheel and threading knob. Be sure to use
the washer between the flywheel and nut.
When attaching the front cover, replace the short
screw as indicated in the illustration.
