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).

MAINTENANCE
TO CHARGE THE 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. Leave the solution tank open.
MACHINES EQUIPPED WITH ONBOARD CHARGER
1.Fully open Recovery Tank/Battery Cover or prop in partially open position using bracket (included). This will provide additional venting of batteries during charging cycle.
2.Connect charger’s AC power cord to AC mains. The charger’s YELLOW “AC” LED will light.
NOTE: When charger is energized, all machine function will shut down.
3.After several seconds, the charger’s green LED will flash to indicate that charging is in process.
NOTE: If no lights are illuminated, or yellow LED flashes, refer to the charger Product Manual Troubleshooting section.
4.When charging is complete, both the yellow and green LEDs will remain on. The charger is now in standby mode.
5.Disconnect charger’s AC power cord.
6.Raise battery cover and check the battery electrolyte level. It should be up to the indicator ring. If necessary, add distilled water.
7.Lower the battery cover
NOTE: For additional information about battery charger function, please see the charger Product Manual.
