WARNING:
ADHESIVES AND SOLVENTS ARE
FLAMMABLE AND TOXIC TO THE SKIN,
EYES AND RESPIRATORY TRACT. SKIN
AND EYE PROTECTION ARE REQUIRED.
AVOID PROLONGED CONTACT. USE IN
WELL VENTILATED AREA.
CAUTION:
DO NOT USE ANY SOLVENT DURING
CLEANING THAT COULD SOFTEN OR
DESTROY THE BOND BETWEEN
CHEMICALLY ATTACHED PARTS.
(2) Using a clean cloth dampened with Stoddard solvent
CM23 or equivalent, wipe the inside of the spinner dome
to remove grease, oil, and other residue.
(a) Immediately dry the inside of the spinner dome using
a clean dry cloth.
(3) Using a clean cloth dampened with Stoddard solvent
CM23 or equivalent, wipe the accessible surfaces of the
hub, counterweight clamps, slip ring, and bulkhead to
remove grease, oil, and other residue.
(4) Fill a tank sprayer with a non-caustic/non-acidic soap
solution.
IMPORTANT: WHEN PERFORMING STEPS 5 THRU 7,
THE BLADE(S) TO BE CLEANED
MUST POINT DOWNWARD. THIS WILL
PREVENT THE SOAP SOLUTION AND/OR
CONTAMINANTS FROM FLOWING INTO
THE HUB/BLADE SEAL AREA.
CAUTION:
DO NOT LET THE SOAP SOLUTION
DRY ON THE SURFACES OF THE HUB,
BULKHEAD, OR SLIP RING.
(5) Using the tank sprayer, apply a fine mist of the soap
solution to the surfaces of the downward facing blades,
and the hub, bulkhead, and slip ring around the
downward facing blades.
(a) Use a cloth or soft nylon brush to loosen dirt and
unwanted material on the surfaces where the soap
solution was applied, particularly on the inboard
surface of the counterweight clamp.
