TIRE
INFI.ATION
For maximum service
from the
tires, keep them inflated
to the proper
pressures
-
18
psi for the
nose
gear and
24 psi
for the main gear.
All
wheels
and tires are balanced before original installation, and the
ielationship
of tire, tube
and
wheel should be maintained
upon reinstallation. Unbalanced wheels can
cause
extreme vibration
in
the landing gear;
therefore, in the installation of new components,
it
may be
necessary
to
rebalance
the wheels
with
the tires mounted. When checking
tire pressure,
examine
the
tires
for
weat,
cuts, bruises, and slippage.

normally
closed
off with
a
cap and
which

be opened occasionally
to
drain
off
any accumulation
of liquid. The battery
strould be checked
for proper
fluid
level. DO NOT
fill
the battery
above
the baffle
plates. DO NOT
fill
the battery with acid - use water
only. A hydrometer
check
will determine the percent

charge
in the battery.

a
4 amp rate and finishing
with
a
2
amp rate.
