CHECKING GRAVITY |

Charge batteries in a well ventilated area. Leave | |||||
A. Hydrometer | |||||
B. Battery | the solution tank open. | ||||
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).
Subtract
Use a 24 volt, 20 amp maximum output, DC charger which will automatically shut off when the batteries are fully charged to charge the two battery pack.
1.Stop the machine in a clean, well ventilated area next to the charger.
2.Turn the machine power off.
FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key.
3.Drain solution tank and raise the solution tank and lock the support arm. Make sure the support arm is fully engaged.
!
Batteries emit hydrogen gas. Explosion or fire can result. Keep sparks and open flame away. Keep covers open when charging.
