WARNING
!
!
Hazard of explosive gas mixture. Keep sparks, flame, and smoking
material away from battery.
Always wear safety glasses when working with batteries.
Battery posts, terminals and related accessories contain lead and
lead compounds, chemicals known to the State of California to
cause cancer and reproductive harm.
Wash hands after handling.
Battery fluid is highly corrosive. Thoroughly rinse away any spilled
fluid with clean water.
Always replace batteries with UpRight batteries or manufacturer
approved replacements.
Check battery fluid level daily, especially if the work platform is
being used in a warm, dry climate.
If the electrolyte level is lower than 10 mm (
3/8 in.
) above plates,
add distilled water ONLY. Do not use tap water with high mineral
content; it will shorten battery life.
The battery and cables should be inspected regularly for signs of cracks in the case, electrolyte leakage
and corrosion of the terminals. Inspect the cables for worn spots or breaks in the insulation and for broken
cable terminals.
Refer to the Service Manual to extend battery life and for complete service instructions.
