ELECTRICAL SYSTEM
BATTERY
The battery is rated at 12 V, 625 ccA. It is located
next to the engine and hydraulic pump.
Do not allow the battery to remain in discharged
condition for any length of time.
Do not operate the machine if the battery is in poor
condition or discharged beyond 80%, specific gravity
below 1.130.
Clean the top surface and the terminals of the
battery periodically. Use a strong solution of baking
soda and water. Brush the solution sparingly over the
battery top, terminals, and cable clamps. Do not
allow any baking soda solution to enter the battery.
Use a wire brush to clean the terminal posts and the
cable connectors. After cleaning, apply a coating of
clear petroleum jelly to the terminals and the cable
connectors. Keep the top of the battery clean and
dry.
Keep all metallic objects off the top of the battery, as
they may cause a short circuit. Replace worn or
damaged wires.
The electrolyte level must always be above the
battery plates. Add distilled water to maintain
solution at the correct level above the plates, but do
not overfill. Never add acid to batteries, only water.
Keep vent plugs firmly in place at all times, except
when adding water or taking hydrometer readings.
WARNING: Avoid contact with battery
acid. Battery acid can cause severe burns.
Wash immediately and get medical attention if
contact with battery acid occurs.
If when checking battery specific gravity, one or
more battery cells tests lower than the other battery
cells, (0.050 or more) the cell is damaged, shorted,
or is about to fail.
NOTE: Do not take readings immediately after
adding water--- ---if the water and acid are not
thoroughly mixed, the readings may not be accurate.
Check the hydrometer readings against this chart:
SPECIFIC GRAVITY BATTERY
at 80
_
F (27
_
C) CONDITION
1.260 --- 1.280 100% charged
1.230 --- 1.250 75% charged
1.200 --- 1.220 50% charged
1.170 --- 1.190 25% charged
1.110 --- 1.130 Discharged
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80
_
F (27
_
C), the reading must be temperature corrected.
To determine the corrected specific gravity reading
when the temperature of the battery electrolyte is
other than 80
_
F (27
_
C):
Add to the specific gravity reading 0.004, 4 points,
for each 10
_
F (6
_
C) above 80
_
F (27
_
C).
Subtract from the specific gravity reading 0.004, 4
points for each 10
_
F (6
_
C) below 80
_
F (27
_
C).
When removing battery cables, remove the negative
(---) cable before the positive (+) cable.
CAUTION: Always remove the negative (--)
battery cable before the positive (+) battery
cable to prevent accidental electrical shorting and
personal injury.
