CAUTION
!
If battery water level is not maintained, batteries will not fully charge, creating a low
discharge rate which will damage motor/pump unit and void warranty.
Batteries should be inspected periodically for signs of cracks in the cases, electrolyte
leakage and corrosion of the terminals. Inspect cables for worn spots or breaks in the
insulation and for broken cable terminals.
Clean any batteries that show signs of corrosion at the terminals or which electrolyte has
overflowed onto during charging. Use a baking soda solution to clean the batteries, taking
care not to get the solution inside the cells. Rinse thoroughly with clear water. Clean bat-
tery and cable contact surfaces to a bright metal finish whenever a cable is removed.

CAUTION
!
Charge the batteries at the end of each work shift or sooner if the batteries have
been discharged.
Charge batteries in a well ventilated area.
Do not charge batteries when the work platform is in an area containing sparks or
flames.
Permanent damage to batteries will result if batteries are not immediately recharged
after discharging.
Never leave charger operating unattended for more than two days.
Never disconnect cables from batteries when charger is operating.
Keep charger dry.
1. Check battery fluid level. If electrolyte level is lower than 3/8 in. [10mm] above plates
add distilled water only.
2. The plug for the battery charger is located at the right side of the power module.
Connect extension cord (1.5 mm² [12 gauge] conductor minimum and 15 m [50 ft.] in
length maximum) to the charger plug. Connect other end of extension cord to prop-
erly grounded outlet of proper voltage and frequency.
NOTE: Charger circuit must be
used with a GFI (Ground Fault
Circuit Interrupt) outlet.
3. Charger turns on automatically after a short delay. The ammeter will indicate charg-
ing current.
NOTE: Do not operate the
machine while it is plugged into
the charger
4. Charger turns off automatically when batteries are fully charged.
