Be sure the ignition switch is
"OFF",
the
throttle closed, and mixture eontroi in the idle
cut-off position before turning the propeller. Do
not stand in the path of propeller blades. Also,
ground running the engine for brief periodsof
time is not a substitute for turning the engine
over by hand; in fact, the practice of ground
running will tend to aggravate rather than
minimize corrosion formation in the engine.
After 30 days, the aircraft should be flown for 30 minutes
or a ground runu p should be made long enough to produce
an oil temperature within the lower green arc range . Ex-
cessive ground runup should be avoided .
PREPARA T/ON FOR SERVICE
Remove all covers, clean the airplane, and give it a
thorough inspection, particularly flaps and eontroi
openings.
Preflight the airplane .

mary objectives of these measures are to prevent corro-
sion and damage from exposure to the elements.
