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.
SPECIFIC GRAVITY | BATTERY CONDITION |
@ 80° F (27°C) |
|
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).

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.Empty recovery tank.
2.Stop the machine in a clean, well ventilated area next to the charger.
3.Turn “OFF” machine.
FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key.
4.Unplug the machine from the battery pack. Remove front cover. Disconnect recovery hose from “Y” tube. Raise recovery tank and verify prop rod latch is safely engaged.
Batteries emit hydrogen gas. Explosion or fire can result. Keep sparks and open flame away. Keep covers open when charging.
5.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.
