PROCEDURES
DAILY (continued)
OÍL
DIPSTICK:
Check oil level before each flight. Do not operate on
less than 9
quarts.
To
minimize loss
of
oil through breather,
fill to 10 quart
level
for normal flights of less than 3 hours. For extended
flight, fill
to 12
quarts.
If
optional oil filter
is installed,
one additional
quart is
required
when the filter element is changed.
OIL DIPSTICK
CALIBRATIONS
o O
o
A
The engine
oil
dipstick in your airplane
is
calibrated for
both
landplane and
floatplane/amphibian
use. Oil level
readings
for
the
floatplane/amphibian
will
register
considerably
below the
equivalent calibrations for the landplane due to the difference in
attitude of the airplanes when
being
serviced. When
checking
the oil
level, take precautions to assure that you are
using
the
correct calibrations for the configuration
of
your airplane.
The landplane side of the dipstick
is
marked with four lines
representing
the
six, eight,
ten and twelve quart levels.
The
bottom
line is the six quart level and the top line is
the twelve
quart (full)
level. The floatplanefamphibian side of the
dip-
stick has two
asterisk
marks.
The
lower asterisk indicates
nine quarts and the upper
asterisk
indicates
twelve
quarts.

OXYGEN CYLINDER AND
FILLER VALVE
(OPT)
Check oxygen
pressure gage for
anticipated requirements
before
each flight.
Use filler
valve
located on
left
side
of fuselage aft
of
cabin windows
under round
cover plate to refill
cylinder
with
aviator's
breathing
oxygen (Spec. No.
MIL-O-27210).
Maximum
pressure (cylinder
temperature stabilized after
filling),
1800 psi
at
70°F.
