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.
