SECTION VI
GENERAL
MAINTENANCE
This
section
contains
information
for
minor
maintenance
of
the
airplane.
For
further
maintenance
assistance
refer to the Cherokee
140
"D"
Service
Manual.
Any
complex
repairs
or
modification
should
be
accomplished
by
a Piper Certified
Service Center
or equivalent.
TIRE INFLATION
For maximum
service
from
the tires,
inflate
them
to
the
proper
pressure
of 24
pounds for
all three
wheels.
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.
Out of
balance
wheels
can cause extreme
vibration
on
take-off.
In the
installation
of
new components,
it
may
be
necessary
to rebalance
the wheel with the
tires mounted.
BATTERY
SERVICE
The
12
volt
battery is located in
a stainless
steel
container
under
the
baggage
compartment
floor.
This
container
should
be drained
occasionally
by
opening
the rubber
cap on the
drain
tube. Check
the
battery
for proper fluid level (below
the
baffle plates)
and use a
hydrometer
to
determine
the
density
of the
battery fluid.
If the
battery is discharged,
charge
it before
take-off
as three volts
are
needed
to excite the
alternator.
To recharge,
start at a 4
ampere
rate
and
finish
with a 2 ampere
rate.
Quick
charges are
not
recommended.
