BATTERIES (WET CELL BATTERIES ONLY)
The batteries provide the power to operate the
machine. The batteries require regular maintenance
to keep them operating at peak efficiency.
The machine batteries will hold their charge for long
periods of time, but they can only be charged a
certain number of times. To get the greatest life
from the batteries, charge them when their charge
level reaches 25% of a full charge. Use a
hydrometer to check the charge level.
Do not allow the batteries to remain in a discharged
condition for any length of time. Never expose a
discharged battery to temperatures below freezing.
Discharged batteries will freeze causing cracked
cases. Do not operate the machine if the batteries
are in poor condition or if they have a charge level
below 25% (specific gravity below 1.155).
Keep all metallic objects off the top of the batteries,
as they may cause a short circuit. Replace worn or
damaged cables and terminals.
Check the electrolyte level in each battery cell
before and after charging the batteries. Never add
acid to the batteries, use distilled water. Do not
allow water level to fall below the battery plates.
Portions of plates exposed to air will be destroyed.
Do not overfill. Keep plugs firmly in place at all
times.
When servicing machine, avoid contact with
battery acid.
Batteries emit hydrogen gas. Explosion or fire
can result. Keep sparks and open flame away.
Keep covers open when charging.
Wear eye protection and protective clothing
when working with batteries.
Charge batteries in a well ventilated area.
BATTERY MAINTENANCE
1. When cleaning the batteries, use a solution of
baking soda and water. Do not allow the
cleaning fluid to enter the battery cells,
electrolyte will be neutralized.
2. Maintain the proper electrolyte level in each
battery cell. If a cell should accidentally
overflow, clean immediately.
3. Wipe off the top of the batteries at least once a
week.
4. Test battery condition with a hydrometer at least
once a week.
5. Ensure that all connections are tight and all
corrosion removed.
6. Every 4 to 6 months remove the batteries from
the machine and clean the battery cases and
battery compartment.
