ignored, may result in cracks. Never use an alkaline cleaner on the
blades; remove grease and dirt with carbon tetrachloride or Stoddard
solvent.
INTERIOR CARE.
To remove dust and loose dirt from the upholstery and carpet, clean the
interior regularly with a vacuum cleaner.
Blot up any spilled liquid promptly, with cleansing tissue or rags. Don't
pat the spot; press the blotting material firmly and hold it for several seconds.
Continue blotting until no more liquid is taken up. Scrape off sticky
materials with a dull knife, then spot-clean the area.
Oily spots may be cleaned with household spot removers, used sparingly.
Before using any solvent, read the instructions on the container and test it on
an obscure place on the fabric to be cleaned. Never saturate the fabric with a
volatile solvent; it may damage the padding and backing materials.
Soiled upholstery and carpet may be cleaned with foam-type detergent,
used according to the manufacturer's instructions. To minimize wetting the
fabric, keep the foam as dry as possible and remove it with a vacuum
cleaner.
If your airplane is equipped with leather seating, cleaning of the seats is
accomplished using a soft cloth or sponge dipped in mild soap suds. The soap
suds, used sparingly, will remove traces of dirt and grease. The soap should
be removed with a clean damp cloth.
The plastic trim, headliner, instrument panel and control knobs need
only be wiped off with a damp cloth. Oil and grease on the control wheel and
control knobs can be removed with a cloth moistened with Stoddard solvent.
Volatile solvents, such as mentioned in paragraphs on care of the
windshield, must never be used since they soften and craze the plastic.
Radio and autopilot face plates are finished with a suede coating which
produces a soft, rich appearance and warm feel comparable to suede. Unlike
suede leather, dust and dirt marks can be removed easily with a damp
sponge. Remove non-greasy stains with a liquid cleaner such as "Mr. Clean",
"Handy Andy", "Lestoil", "Liquid Ajax", or "Cinch". Greasy stains can be
removed with a naphtha-dampened sponge, scrub brush or lint-free cloth.
FLYABLE STORAGE.
Aircraft placed in non-operational storage for a maximum of 30 days or
those which receive only intermittent operational use for the first 25 hours are
considered in flyable storage status. Every seventh day during these periods,
the propeller should be rotated by hand through five revolutions. This action
"limbers" the oil and prevents any accumulation of corrosion on engine
cylinder walls.
IMPORTANT
For maximum safety, check that the ignition switch is OFF,
the throttle is closed and the mixture control is in the idle
cut-off position before rotating the propeller by hand. Do
not stand within the arc of the propeller
blades while turning
the propeller.
After 30 days, the aircraft should be flown for 30 minutes or a ground
runup should be made just long enough to produce an oil temperature within
the lower green arc range. Excessive ground runup should be avoided.
Engine runup also helps to eliminate excessive accumulations of water in
the fuel system and other air spaces in the engine. Keep fuel tanks full to
minimize condensation in the tanks. Keep the battery fully charged to prevent
the electrolyte from freezing in cold weather. If the aircraft is to be stored
temporarily, or indefinitely, refer to the Service Manual for proper storage
procedures.
INSPECTION SERVICE AND INSPECTION PERIODS.
With your airplane you will receive an Owner's Service Policy. Coupons
attached to the policy entitle you to an initial inspection and the first 100-hour
inspection at no charge. If you take delivery from your Dealer, he will perform
the initial inspection before delivery of the airplane to you. If you pick up the
airplane at the factory, plan to take it to your Dealer reasonably soon after you
take delivery on it. This will permit him to check it over and to make any
minor adjustments that may appear necessary. Also, plan an inspection by
your Dealer at 100 hours or 180 days, whichever comes first. This inspection
also is performed by your Dealer for you at no charge. While these important
inspections will be performed for you by any Cessna Dealer, in most cases you
will prefer to have the Dealer from whom you purchased the airplane
accomplish this work.
