PREVENTING
BATTERY
DAMAGE
1.
Be sure alternator connections are correct before cables are connected
to
battery. See "Preventing
Alternator and Regulator Damage" in this section.
2. Carefully observe polarity
when
attaching booster battery.
3.
Do
not
operate
the
engine with alternator
or
battery disconnected.
A
WARNING:
With
battery
cables
disconnected
and
engine
running, a high
voltage
can
be
built
up
if
tenninals
touch
the
frame.
Anyone
touching
the
frame
under
these
conditions
would
be
severely
shocked.
4.
Do
not short across battery
or
alternator terminals,
or
allow battery positive (
+)
cable
or
alternator wire
to
become grounded.
5.
Do
not
polarize the alternator.
6. When welding
on
any
part
of
the machine, disconnect battery cables and alternator wire.
7.
To
prolong battery life, store batteries fully charged and
at
+20•
to
+80°F
(-7•
to
+26•C). Check voltage
after storage and recharge as needed, according
to
battery and charger manufacturer recommendations.
a.
Do
not stack storage batteries
on
top
of
each other.
A
CAUTION:
When
working
around
storage
batteries.
remember
that
all of the exposed
metal
parts
are iive•.
Never
lay a
metal
object across the
terminals
because
a spark or short
circuit
wil
resut.
BATTERY
MAIITTENANCE
A
CAUTION: Do not attempt
to
service battery unless
you
have
the
proper equipment
and
experience
to
perform the job. Have
it
done
by a qualified dealer.
1.
Check fluid level once a year.
If
necessary add distilled water (or clean rain water)
to
bring level
to
bottom
of
cell neck. Do
not
add water in freezing temperatures unless engine is run
two
to
three hours
to
mix
electrolyte.
2. Check battery charge once a year, more often
if operating in cold weather. Hydrometer readings should
be 1.260
to
1.300. Readings below 1.250 indicate charging is required. See "Charging Battery".
3. Keep battery clean
by
wiping it with a
damp
cloth.
4. Keep all connections clean and tight. Remove
any
corrosion and wash terminals with a solution
of
baking
soda and water. A light coating
of
grease
on
terminals (after cables are attached) will reduce corrosion.
5. A replacement battery must have a rating
of
at
least 640 (Diesel) / 560 (Gas) cold cranking
amps
at
o·
F
(-18•C).
IMPORTANT
: BATTERY
IS
NEGATIVE GROUNDED. Always connect starter cable
to
the positive
(+}terminal
of
battery and battery ground cable
to
negative
(-)
terminal
of
battery. Reversed polarity in battery
or
alternator may result in permanent damage
to
electrical system.
