B-1
Inspect the Engine Start Battery
or Lighting Battery Pack
Terex specifi cations requires that this procedure be
performed every 250 hours or quarterly, whichever
comes fi rst.
Proper battery condition is essential to good
machine performance and operational safety.
Improper fl uid levels or damaged cables and
connections can result in component damage and
hazardous conditions.
WARNING
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
WARNING
Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid. Neutralize
battery acid spills with baking
soda and water.
1 Open the side covers.
2 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.
3 Be sure that the battery retainers and cable
connections are tight.
4 Fully charge the batteries. Allow the batteries to
rest 24 hours before performing this procedure
to allow the battery cells to equalize.
5 Put on protective clothing and eye wear.
6 Remove the battery vent caps and check the
specifi c gravity of each battery cell with a
hydrometer. Note the results.
7 Check the ambient air temperature and adjust
the specifi c gravity reading for each cell as
follows:
• Add 0.004 to the reading of each cell for
every 10° / 5.5° C above 80° F / 26.7° C.
• Subtract 0.004 from the reading of each cell for
every 10° / 5.5° C below 80° F / 26.7° C.
Result: All battery cells display an adjusted
specifi c gravity of 1.277 +/- 0.007. The battery
is fully charged. Proceed to step 11.
Result: One or more battery cells display a
specifi c gravity of 1.269 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
specifi c gravity of each battery cell with a
hydrometer. Note the results.
