Checklist B Procedures
B-1
Inspect the Batteries
We require that this procedure be performed
every 250 hours or quarterly, whichever
comes first.
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 / burn 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.
1 Put on protective clothing and eye wear.
2 Side out tray and away from the chassis.
3 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.
4 Be sure that the battery retainers and
cable connections are tight.
5 Fully charge the batteries. Allow the
batteries to rest 24 hours before
performing this procedure to allow the
battery cells to equalize.
Models without maintenance-free or sealed
batteries:
6 Remove the battery vent caps and check
the specific gravity of each battery cell with
a hydrometer. Note the results.
7 Check the ambient air temperature and
adjust the specific gravity reading for each
cell as follows:
• Add 0.004 to the reading of each cell for
every 5.5° C above 26.7° C.
• Subtract 0.004 from the reading of each
cell for every 5.5° C below 26.7° C.
⊙
Result: All battery cells display an adjusted
specific gravity of 1 .277 or higher. The
battery is fully charged. Proceed to step 11.
¤
Result: One or more battery cells display a
specific gravity of 1.217 or below. Proceed
to step 8.
8 Perform an equalizing charge OR fully
charge the batteries and allow the
batteries to rest at least 6 hours.
9 Remove the battery vent caps and check
the specific gravity of each battery cell with
a hydrometer. Note the results.
10 Check the ambient air temperature and
adjust the specific gravity reading for each
cell as follows:
• Add 0.004 to the reading of each cell for
every 5.5° C above 26.7° C.
• Subtract 0.004 from the reading of each
cell for every 5.5° C below 26.7° C.
⊙
Result: All battery cells display a specific
gravity of 1 .277 or greater. The battery is
fully charged. Proceed to step 11.

Result: The difference in specific gravity
