CLEANING AND CARE (Continued)
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 blade life. Small nicks on the propeller, particularly near the
tips and on the leading edges, should be dressed out as soon as
possible since these nicks produce stress concentrations, and if
ignored, may result in cracks or failure of the propeller blade. Never use
an alkaline cleaner on the blades; remove grease and dirt with
Stoddard solvent.
ENGINE CARE
The engine may be cleaned, using a suitable solvent, in accordance
with instructions in the Maintenance Manual. Most efficient cleaning is
done using a spray type cleaner. Before spray cleaning, ensure that
protection is afforded for components which might be adversely
affected by the solvent. Refer to the airplane Maintenance Manual for
proper lubrication of controls and components after engine cleaning.
The induction air filter should be replaced when its condition warrants,
not to exceed 500 hours.
