CHECKING BATTERY SPECIFIC GRAVITY
Use a hydrometer to check the battery specific
gravity.
CHECKING GRAVITY
A. Hydrometer
B. Battery
NOTE: Do not take readings immediately after
adding distilled water, if the water and acid are not
thoroughly mixed, the reading may not be accurate.
Check the hydrometer readings against this chart.

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.
To find the corrected specific gravity reading when
the temperature of the battery electrolyte is other
than 80°F (27°): Add (+) to the specific gravity
reading 0.004 (4 points), for each 10°F (6°C) above
80° (27°C).
Subtract (-) from the specific reading 0.004 (4
points), for each 10°F (6°C) below 80°F (27°C).
CHARGING BATTERIES
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.
Use a 36 volt, 20 amp maximum output DC charger
which will automatically shut off when the batteries
are fully charged.
1. Stop the machine in a clean, well ventilated area
next to the charger.
2. Turn “OFF” machine.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
3. Remove rear cover, unplug batteries from
machine, unlatch battery tray and pull out to
expose batteries.
Batteries emit hydrogen
gas. Explosion or fire
can result. Keep sparks and open flame away.
Keep covers open when charging.
4. Check the electrolyte level in each battery cell.
Before charging, add just enough distilled water
to cover the plates. After charging is complete,
add just enough distilled water to bring up the
level to the indicator ring. If the water level is
too high before charging, normal expansion rate
of the electrolyte may cause an overflow
resulting in a loss of battery acid balance and
damage the machine.
