MANUAL
SERVICING
Proper
and
periodic
servicing
of the
airplane
will
prevent
considerable
wear
and
greatly lengthen
the service
life of
parts
and
systems
involved.
For
points
of
lubrication
and the
correct
interval
and
materials,
refer
to
the
LUBRICATION
SCHEDULE
and
SERVICING
SCHEDULE.
I
BATTERY
The
battery
is
located
beneath
the
baggage
compartment
floor
on
the
right-hand
side
and
is accessib~e
for
servlcrng
by
opening
the
access
door
on
the
baggage
compartment
floor.
LEAD
ACID
BATTERIES
Never add
anything
but distilled
water
to
the lead
acid
battery.
The
water
level
in
the
battery
should be maintained
at
1/2
inch
above
the
separators.
NOTE:
Do
not
overfill.
When the
battery
cells
are
overfilled,
water
and acid
may
spill
on
the
lower
port~on
of
the
fuselage.
NICKEL-CADMIUM
BATTERIES
The
following
list of
battery
servicing
precautions
and
checks
is
meant to
be
a
guide.
For
specific
deta~ls and
a
complete
procedure,
see
Section
13.
a.
After each
100
hours
of
operation
or
every
30
days,
whichever
occurs
first,
check
the
electrolyte
revel and
clean
the
battery
and
filler
vent
plugs.
b.
Any
time
the
battery
is
subjected
to
more
than 32
volts for
as
long
as
2
minutes,
the
battery
must
be
completety
serviced.
Clean
the
battery, charge
it,
and
adjust
the
electrolyte
level.
c.
Periodically
check
that the cell
vents
are
clean and
open.
Plugged
vents
may
cause
excess
internal cell
pressure
and
cause
leaks.
d.
Never
remove
a
cellfrom
the
battery
case
unless
a
replacement
is
immediately
available;
otherwise,
the
remaining
cells
may
swell,
making replacement
of the
removed cell
difficult. Loosen
the
vent before
cell
replacement
to
eliminate
the
possibility
of
cells
swelling
from
internal
gas
pressure.
e.
Check
the
torque
of
the terminal
screws
securing
the
cross-links
connecting
the
cells
together.
This
torque
should
be from
48
to
60
inch-pounds
(4
to
5
foot-pounds).
f.
Check
that
no
carbon
deposit
has
built
up
on
the cross-links
or
between
them
and the
battery
case.
If
such
deposits
are
present,
clean the
affected
area as
indicated under
Cleaning
and
Inspection,
Section
13.
g.
When
there
is
any
indication
of
oil
in
the
battery,
remove
allcells
from the
case
and
check all rubber
parts
for
deterioration.
Remove
the oil and
replace
all
damaged
rubber
parts.
Do
not
use a
solvent;
use
soap
and
water
only.
h.
Do
not
add
electrolyte
just
because
the level
in
the
battery
is low.
If
electrolyte
is added
instead of
distilled
water
each
time
the
battery
is
low,
the
high
concentration of
electrolyte
may
cause
dissolution of the
prates
under
high
temperature
conditions.
This is indicated
by
the
presence
of black
particles
in
the
affected
cells.
i.
Keep
nickel-cadmium
and lead-acid batteries
stored
separately
to
prevent
mutual
contamination.
Unless
kept
in
closed
storage
containers,
nickel-cadmium
electrolyte
(potassium hydroxide)
will absorb
enough
carbon
dioxide
from the
air
to
render it
ineffective.
