BATTERY
Batteries are supplied by the equipment manufacturer.
A 12-voit battery with a rating of 250 (minimum) cold
cranking amps is normally used.
Refer to the equip-
ment manufacturer's instructions for specific
information.
Battery Test
if the battery charge is not sufficient to crank the en-
gine, recharge the battery.
NOTE:
Do not attempt to "jump start" the engine with
another battery. Starting the engine with bat-
teries larger than those recommended can
burn out the starter motor.
Test the battery voltage by connecting DC voltmeter
across the battery terrninals--crank the engine. If the
battery drops below 9 volts while cranking, the battery
is discharged or faulty. Refer to Figure 8-14.

ELECTRICAL SYSTEM AND COMPONENTS
Battery Charging
WARNING:
Dangerous Acid, Explosive
Gases!
Batteries contain sulfuric acid, To prevent acid
burns, avoid contact with skin, eyes, and clothing.
Batteries produce explosive hydrogen gas while be-
ing charged. Charge the battery in well-ventilated
areas. Keep cigarettes, sparks, open flame, and
other sources of ignition away from battery at all
times.
To prevent accidental shorting and the resulting
sparks, remove ай! jewelry when servicing the
battery.
When disconnecting battery cables, always disc
nect the negative (-) (ground) cable first. When
on-
connecting battery cables, always connect the neg-
ative cable last.
Before disconnecting the negative (-) ground cable,
make sure all switches are OFF. If ON, a spark will
occur at the ground cable terminal which could
cause an explosion if hydrogen gas or gasoline
pors are present.

Keep batteries and acid out of the reach of children.
Battery Maintenance
Regular maintenance will ensure the battery will a
cept and hold a charge.
1. Regularly check the level of electrolyte. Add
tilled water as necessary to maintain the reco
mended level,
NOTE:
Do not overfill the battery.
Poor perfo
ance or early failure due to loss of electro-
lyte will result.
2. Keep the cables, terminals, and external surfa
of battery clean. A build-up of corrosive acid
C-
dis-
m-
rm-
ces
or
grime on the external surfaces can self-discharge
the battery. Self-discharging happens rapidly
when moisture is present.
Wash the cables, terminals, and extemal surfaces
with a baking soda and water solution.
Rinse
thoroughly with clear water.
