CAUTION 1: OVER LUBRICATING AN ALUMINUM HUB
PROPELLER MAY CAUSE THE GREASE
TO ENTER THE CENTRAL HUB CAVITY,
LEADING TO EXCESSIVE VIBRATION
AND/OR SLUGGISH OPERATION.
THE PROPELLER MUST THEN BE
DISASSEMBLED TO REMOVE THIS
GREASE.
CAUTION 2:
IF A PNEUMATIC GREASE GUN IS USED,
EXTRA CARE MUST BE TAKEN TO AVOID
EXCESSIVE PRESSURE BUILDUP.
CAUTION 3:
GREASE MUST BE APPLIED TO ALL
BLADES OF A PROPELLER ASSEMBLY AT
THE TIME OF LUBRICATION.
CAUTION 4: DO NOT ATTEMPT TO PUMP MORE THAN
1 FL. OZ. (30 ML) OF GREASE INTO THE
LUBRICATION FITTING. USING MORE
THAN 1 FL. OZ. (30 ML) OF GREASE
COULD RESULT IN OVER SERVICING OF
THE PROPELLER.
(8) Pump a maximum of
1 fl. oz. (30 ml) grease into the
lubrication fitting
, or until grease emerges from the hole
where the lubrication
fitting
or lubrication hole plug was
removed, whichever occurs first.
NOTE
: 1 fl. oz. (30 ml) is approximately 6 pumps with
a hand-operated grease gun.
(a) For all tractor or pusher propellers with clockwise
