Service and Repair
Battery Charging
The battery is charged by the alternator whenever the engine is running and should not require any other
charging. If the machine has not been in service or if for some other reason the battery has been discharged,
perform the following:
W A R N I N G
!
Charge the battery only in a well ventilated
area.
Do not charge the battery when the work plat-
form is in an area containing sparks or flames.
Always follow the charger manufacturer instruc-
tions.
Never disconnect the cables from the batteries
when the charger is operating.
Check the battery fluid level. If the electrolyte level is lower than 10 mm (3/8 in.) above the plates, add clean,
distilled water only.
Battery Specific Gravity
After charging, if necessary, the specific gravity of all cells should be checked with a hydrometer. The tempera-
ture corrected specific gravity should be 1.260. If the battery contains any cells with corrected readings below
1.230, the battery 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 1 to 2 hours to
adequately mix the water and electrolyte.
