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)
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.
