PROPELLER CARE
Preflight inspection of propeller blades for nicks, and
wiping them occasionally with an oily cloth to clean off
grass and bug stains will assure long, trouble-free service.
It is vital that small nicks on the propellers, particularly
near the tips and on the leading edges, are dressed out as
soon as possible since these nicks produce stress concentra-
tions, and if ignored, may result in cracks.
Never use an
alkaline cleaner on the blades; remove grease and dirt with
Stoddard solvent.
Do not feather propeller below 700 RPM as
this may damage the hub mechanism.
INTERIOR CARE
To remove dust and loose dirt from the upholstery,
headliner, 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 instruc-
tions 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 instruc-
tions.
To minimize wetting the fabric, keep the foam as dry
as possible and remove it with a vacuum cleaner.
The plastic trim, instrument panel and control knobs
need only be wiped with a damp cloth.
Oil and grease on the
control wheel and control knobs can be removed with a cloth
moistened with
kero~ene.
Volatile solvents, such as men-
tioned in paragraphs on care of the windshield, must never be
used since they soften and craze the plastic.
