Checklist B Procedures
B-1
Inspect the Batteries
Proper battery condition is essential to good
machine performance and operational safety. A
faulty battery cell can result in poor machine
performance and improper fluid levels or damaged
cables and connections can result in component
damage and hazardous conditions.
Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid. Neutralize
battery acid spills with baking soda
and water.
Electrocution hazard. Contact with
hot or live circuits could result in
death or serious injury. Remove all
rings, watches and other jewelry.
Perform this test after fully
charging the battery.
For a more accurate determination
of battery condition, fully charge
the batteries and allow the
batteries to rest for 24 hours
before performing this procedure.
This will allow the battery cells to
equalize.
1 Put on protective clothing and eye wear.
2 Be sure that the battery cable connections are
tight and free of corrosion.
3 Be sure that the battery retaining fasteners are
in place and secure.
4 Remove the battery vent caps from all batteries
and check the specific gravity of each battery
cell with a hydrometer.
Result: If any battery cell displays a specific
gravity of less than 1.026, the battery must be
replaced.
5 Check the battery acid level of each battery. If
needed, replenish with distilled water to the
bottom of each battery fill tube. Do not overfill.
6 Install the battery vent caps.
7 Check each battery pack and verify that the
batteries are wired correctly. Refer to the
Battery Connection Diagram decal on the
machine.
8 Inspect the battery charger plug and pigtail for
damage or excessive insulation wear. Replace
as required.
