on
leveling
screwd looated
on

FLYABLE STORAGE
Airplanes placed in
non-operationa,l storage
f
or
a
maximum
of
30
days
or those which receive only intermittent operational
use
for the
first
25
hours are considered
in flyable storage
status.
Every
seventh day
during
these periods,
the propeller should
be rotated
by
hand through five
revolutions. This aotion "limbers" the oil
and
prevents
any a,ccumulation
of
corrosion on engine cylinder walls.
WARNING
For maximum
safety, check
that the ignition switch is
OFF, the
throttle is
closed, the
mixture control
is in the
idle
cut-off position,
andthe

rotating
the propeller by hand.
Do
not
stand
within tho
arc
of
the
propeller
blades
while turning the propeller.
After
30
days,
the airplane should
be
flown for
30
minutes
or
a
ground
runup should
be made
just
Long
enough
to produce an
oil
temperature
within the lower
green arc range. Excessive ground runup should
be
avoided.
Engine runup also helps to
eliminate excessive accumulations
of
water
in
the
fuel
system
and
other air spacesinthe
engine.
Keopfuel tanks
i
full

condensation
in
the
tanks.
