SECTION 8 - GENERAL SPECIFICATIONS & OPERATOR MAINTENANCE
Monthly maintenance
Checking voltage and electrolyte specific gravity
NOTE: Voltage and specific gravity measures should not
be performed after battery cells have been filled.
These measures must be done after a complete
charge once the charger has been unplugged and
the machine has been standing for 15 mn.
• Open the battery cell filling cap.
• Using the hydrometer, take a quantity of electrolyte
sufficient so that the float emerges. Ensure the float
top does not touch the rubber bulb or that the float
does not stick by capillarity to the glass wall.
• Read the value as indicated on the example below :
• Return the electrolyte in the cell and record cell
electrolyte specific gravity in the battery service log.
• Repeat operation for each battery cell.
• Contact JLG Industries if important disparities are
noticed between the gravity of the different cells and
if the values are lower than 1.24.
• Check each cell voltage.
• Contact JLG Industries if important disparities are
noticed between the voltage of the different cells.
Annual maintenance
Filling system maintenance
It is necessary to service the centralized filling system
at least once a year. Cleaning frequency must be
increased in case of premature clogging of the filter or
a reduction in water flow.
• Disconnect and clean the filter by reversing the
water flow from the normal direction.
• Check the hoses for flexibility. In case of hardening
in the connection areas, replace the hose.
• Check every fitting for tightness and leakage.
• Check the cell caps individually. Ensure the perfect
mobility of the floats. In case of excessive clogging,
replace the cap. In any case, it is recommended to
replace the caps every 2 to 3 years.

Various recommendations
Use of a battery in a cold chamber or in a cold climate
Low temperatures decrease battery capacity. The
battery must be fully charged when the work platform
is operated in a cold chamber or in cold weather
condition.
Battery not working continuously or inactive battery
A battery that is not used or used intermittently must be
stored charged in a dry area away from freezing
temperatures. A charge must be performed once a
month.
• Unplug the battery to insulate it electrically.
• Keep the top of the battery clean and dry to prevent
self discharge.
IF THE BATTERY IS NOT USED CONTINUOUSLY, IT MUST BE
RECHARGED BEFORE USE AND AT LEAST ONCE A MONTH, EVEN
IF THE ELECTROLYTE SPECIFIC GRAVITY MEASURES ARE HIGH.
BEFORE PLACING IN SERVICE A BATTERY WHICH REMAINED
INACTIVE FOR A LONG PERIOD OF TIME, YOU MUST RECHARGE
THE BATTERY AND CHECK THE ELECTROLYTE LEVEL IN THE
CELLS
