8 Remove the battery vent caps and check the
specific gravity of each battery cell with a
hydrometer. Note the results.
9 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 10° F / 5.5° C above 80° F / 26.7° C.
• Subtract 0.004 from the reading of each cell for
every 10° F / 5.5° C below 80° F / 26.7° C.
Result: All battery cells display a specific
gravity of 1.277 +/- 0.007. The battery is fully
charged. Proceed to step 10.
Result: One or more battery cells display a
specific gravity from 1.269 to 1.218. The battery
is still usable, but at a lower performance so will
need to be recharged more often. Proceed to
step 11.
Result: One or more battery cells display a
specific gravity from 1.217 to 1.173. The battery
is approaching the end of its life. Proceed to
step 11.
Result: The difference in specific gravity
readings between cells is greater than 0.1 OR
the specific gravity of one or more cells is 1.172
or less. Replace the battery.
10 Check the battery acid level. If needed,
replenish with distilled water to 1 /
8
inch / 3 mm
below the bottom of the battery fill tube. Do not
overfill.
11 Install the vent caps and neutralize any
electrolyte that may have spilled.

Inspect the 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
unsafe operating conditions and may cause
component damage.
Electrocution/burn hazard. Contact
with hot or live circuits could result
in death or serious injury. Remove
all rings, watches and other
jewelry.
1 Open the engine side turntable cover.
2 Remove the safety pin from the engine pivot
plate latch.
Note: The engine pivot plate latch is located under
the engine turntable pivot plate at the counterweight
end of the machine.
3 Open the engine pivot plate latch and swing the
engine pivot plate out and away from the
machine.
4 Inspect the following areas for burnt, chafed,
corroded and loose wires:
• Power units
• Inside of the ground control box
• Generator and power units
• Engine wiring harness
