Inspect the Batteries
Proper battery condition is essential to good
machine performance and operational safety.
Improper fluid levels or damaged cables and
connections can result in component damage and
hazardous conditions.
Electrocution hazard. Contact with
electrically charged circuits could
result in death or serious injury.
Remove all rings, watches and
other jewelry.
Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid. Neutralize
battery acid spills with baking soda
and water.
Perform this procedure after fully
charging the batteries.
For a more accurate determination
of battery condition, fully charge
the batteries and allow the
batteries to rest 24 hours before
performing this procedure to allow
the battery cells to equalize.
