BATTERY MAINTENANCE

Hazard of explosive gas mixture. Keep
sparks, flame and smoking materials away
from batteries.
Always wear safety glasses when working
with batteries.
Battery fluid is highly corrosive. Rinse
away any spilled fluid thoroughly with
clean water.
Always replace batteries with UpRight
batteries or manufacturer approved re-
placements weighing 28 kg. (62 lbs.) each.
Check battery fluid level daily (Figure 4), especially if
work platform is being used in a warm, dry climate.
If electrolyte level is lower than 10 mm (
plates add distilled water only. DO NOT use tap
water with high mineral content, it will shorten
battery life.
Keep terminals and tops of batteries clean.
Refer to the Service Manual to extend battery life
and for complete service instructions.

Battery Charging

Charge batteries at end of each work shift or
sooner if 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 (Figure 4). If electrolyte
level is lower than 10 mm (
add distilled water only.
2. Verify charger voltage switch is set to the correct
voltage.
3. Connect extension cord (1.5 mm² (12 guage)
conductor minimum and 15 m (50 ft.) in length
maximum) to charger plug located at the front
side of the left chassis module (Figure 4). Connect
extension cord to properly grounded outlet of
proper voltage and frequency.
4. Charger turns on automatically after a short delay.
