DRAINING FUEL
SYSTEM
The bulk of
the
fuel
may
be drained
by
opening the
individual
drain
on
each
tank.
The remaining fuel
in the lines
may be drained
through
the fuel
collector
manifold
clrains
(on
early
models only) and the
gascolator
drain.
Any
individual tank
may be
drained
through its
individual drain.
CAUTION
Whenever the
fuel system is completely drained and
fuel is re-
plenished it will be necessary
to run the engine for
a
minimum of
3
minutes
at 1000
RPM on each
tank to insure
no air exists
in the fuel
supply lines.
TIRE
INFLATION
For maximum service
from
the
tires, keep
them
inflated to the
proper pressures.
The
main
gear
tires should
be inflated to 24
psi
and the
nose
gear
should be inflated to
30
psi.
Interchange the
tires on the main
wheels
if necessary to
produce
even wear. All wheels
and
tires
are balanced
before original installation, and the relationship of
the
tire, tube,
and wheel
should
be
maintained if at all
possible.
Unbalanced
wheels
can cause extreme
vibration
on
takeoff.
ln the
installation
of
new components, it may
be
necessary to rebalance the wheel
with
the
tire
mounted.
When
checking
the
pressure,
examine the tires
for
wear,
cuts,
bruises,
and slippage.
BATTERY SERVICE
Access to
the l2-volt battery is
obtained
by
raising
the
rear
seat
and removing
the
cover of
the
battery box. The
plastic
battery box has
a
drain tube
which is
normally
closed
off
with a
cap and
which
should
be
opened occasionally
to drain off any
accumulation
of
liquid.
The battery should
be
checked
for
proper
fluid
level. DO
NOT fill
the battery
above the
baffle
plates.
DO
NOT fill
the
battery
with
acid
-
use
only
water. A
hydrometer
check
will
determine
the
percent
of
charge
in the battery.
If the battery
is not up to charge,
recharge starting at a
4 amp rate and
finishing
with
a 2
amp
rate.
Quick
charges are
ltot
recommended.
WINTERIZATION
For
winter operation a
winterization
plate
is installed
on the inlet
opening
of the
oil
cooler.
This
plate
should be installed
whenever
the ambient
temperature
reaches
50" F
or
less.
The
plate
should
be
removed and stored
in the cockpit
when
the ambient
temperature
exceeds
50"
F.
