HANDLING, SERVICE
&
MAINTENANCE
~~i402C
Remove oil and grease with a cloth moistened with kerosene. Never use
gasoline, benzine, acetone, carbon tetrachloride, fire extinguisher fluid,
lacquer thinner or glass cleaner. These materials will soften the plastic
and may cause it to craze.
After removing dirt and grease, if the surface is not badly scratched,
it should be waxed with a good grade of commercial wax. The wax will fill
in minor scratches and help prevent further scratching. Apply a thin, even
coat of wax and bring it to a high pol ish by rubbing 1ightly with a clean,
dry, soft fl annel cloth. Do not use a power buffer; the heat generated by
the buffing pad may soften the plastic.
Do not use a canvas cover on the windshield unless freezing rain or
sleet is anticipated. Canvas covers may scratch the plastic surface.
OXYGEN MASKS
--
The pilot's mask is a pennanent-type mask which contains a microphone
for radio transmissions. The remaining masks are basically the same as the
pilot's, except they do not have the microphone provision. All masks can
be
cleaned with alcohol. Additional masks and hoses are available from ~
your Cessna Dealer.
