HARGE BATTERY AS FOLLOWS
:
1. Check the fluid level. If the electrolyte level is lower than 3/8 in. (10mm) above the plates,
add clean, distilled water only.
2. Connect the charger plug to a properly grounded outlet of the proper voltage and frequency.
3. The charger turns on automatically after a short delay. The ammeter will indicate DC charg-
ing current.
4. The charger turns off automatically when the batteries are fully charged.

QUALIZATION
Figure 3-8: Power Module
The specific gravity of the electro-
lyte in the battery cells should be
equalized monthly. To do this,
charge the batteries as outlined in
Battery Charging. After this initial
charge, check the electrolyte level
in all cells and add distilled water
as necessary. Turn the charger on
for an additional eight hours. Dur-
ing this time, the charging current
will be low (four amps) as cells are
equalizing.
After equalization, the specific
gravity of all cells should be
checked with a hydrometer. The temperature corrected specific gravity in this state should be
1.260. If any corrected readings are below 1.230, the batteries containing such cells should be
replaced.
Do not check the specific gravity in a cell to which water has just been added. If there is not
enough electrolyte in a fully charged cell to obtain a sample for the hydrometer, add water and
continue charging for one to two hours to adequately mix the water and electrolyte.

! !
Charge the battery only in a well-ventilated area.
Do not charge the battery when the work platform is in an area containing
sparks or flames.
Permanent damage will result if the battery is not immediately recharged
after discharging.
Never leave the charger unattended for more than two days.
Never disconnect the cables from the battery when the charger is operating.
Keep the charger dry.
Never operate the machine while the charger is plugged in.
