BODILY INJURY HAZARD. BATTERIES CONTAIN ACID. AVOID SPILLING
OR CONTACTING BATTERY ACID. NEUTRALIZE BATTERY ACID SPILLS
WITH BAKING SODA AND WATER.
Put on protective clothing and eye wear.
Open the Battery Module.
Be sure that the battery cable connections are free of corrosion.
NOTE: Adding terminal protectors and a corrosion preventative
sealant will help eliminate corrosion on the battery terminals
and cables.
Be sure that the battery retainers and cable connections are
tight.
For refillable batteries, remove the battery caps and inspect
the fluid level. If plates show, add just enough fluid to cover the
plates.
Replace cables that show damage, corrosion, or swelling.
Fully charge the batteries. It is best to allow the batteries to rest
24 hours to allow the battery cells to equalize.
Check each battery pack and verify that the batteries are wired
correctly.
For refillable batteries, check the fluid level in each battery cell.
Batteries are full when the fluid is just below the bottom of the
well.
Inspect the battery charger plug and pigtail for damage or
excessive insulation wear. Replace as required.
Connect the battery charger to a properly grounded 110 - 230V
/ 50 - 60 Hz single phase AC power supply.

Electrical Wiring
Maintaining electrical wiring in good condition is essential to safe operation and good machine
performance. Failure to find and replace burnt, chafed, corroded or pinched wires could result in
machine breakdown or unsafe operating conditions and may cause component damage.
