QUALIZATION
The specific gravity of the electrolyte in the battery cells should be equalized monthly. To do this,
charge batteries as outlined in Battery Charging. After this initial charge, check the electrolyte
level in all cells and add distilled water as necessary. Then, turn the charger on for an additional
eight hours.
After equalization, the specific gravity of all cells should be checked with a hydrometer. The tem-
perature 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.
WARNING
!
!
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.
DO NOT operate the machine while the charger is plugged in.
Keep the charger dry.
