ELECTRICAL SYSTEM
BATTERIES
The six 6-Volt batteries provide all of the energy
used by the machine. The batteries are rated at
220 A/h at a 20-hour rate. The heavy duty
batteries are available as an option on the 1480,
and 1490. They are rated at 305 A/h at a 20 hour
rate. The batteries require regular maintenance to
keep them operating their best.
Periodically clean the top surface and the
terminals and check for loose connections. 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 tops of the batteries
clean and dry.
Check the electrolyte level in each battery cell
before and after charging the batteries. Never add
acid to batteries, only distilled water. Do not
overfill. Keep vent plugs firmly in place at all
times, except when adding water or taking
hydrometer readings.
FOR SAFETY: When Servicing Machine, Avoid
Contact With Battery Acid.
Do not operate machine if batteries are in poor
condition or have a charge level below 25%,
specific gravity below 1.155. Do not allow
batteries to remain in discharged condition for any
length of time.
Keep all metallic objects off the top of the
batteries, as they may cause a short circuit.
Replace worn or damaged wires.
The machine batteries are unique in that they hold
their power for long periods of time, but they can
only be recharged a certain number of times. To
get the most life from the batteries, charge them
when their charge level is below 25%. To
determine the charge level, check the batteries
specific gravity with a hydrometer.

CHECKING BATTERY SPECIFIC GRAVITY
A. Hydrometer
B. Battery
If 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
the following chart:
Specific Gravity

Battery Condition
1.265 100% charged
1.225 75% charged
1.190 50% charged
1.155 25% charged
1.120 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.
