Always wear safety glasses when working with batteries.
Battery fluid is highly corrosive. Thoroughly rinse away any spilled fluid with clean water.
Always replace batteries with UpRight batteries or manufacturer approved replacements
weighing 28 kg. (62 lbs.) each.
• Check battery fluid level daily, especially if work platform is being used in a warm, dry climate.
• If electrolyte level is lower than 10 mm (3/8 in.) above plates, add distilled water ONLY.Donot
use tap water with high mineral content, as it will shorten battery life.
• The battery and cables should be inspected regularly for signs of cracks in the case, electro-
lyte leakage and corrosion of the terminals. Inspect cables for worn spots or breaks in the
insulation and for broken cable terminals. Keep terminals and tops of batteries clean.
• Refer to the Service Manual to extend battery life and for complete service instructions.

distilled water only.
2. Connect extension cord to charger plug at end of left module. Connect extension cord 1.5
mm² (12 gauge)minimum conductor diameter; 15m (50 ft.) maximum length) to properly
grounded outlet of correct voltage and frequency.
NOTE: Charger circuit must be
