Checklist B Procedures

B-1

Inspect the Batteries

Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Proper battery condition is essential to good engine
performance and operational safety. Improper fluid
levels or damaged cables and connections can
result in engine component damage and hazardous
conditions. There are 2 batteries on the machine.
One starts the engine and the other powers the
control system. The batteries are charged by the
alternator through a battery separator.
Electrocution/burn hazard. Contact
with hot or live 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 Open the engine side cover.
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 - 16
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
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 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
specific gravity of 1.277 +/- 0.007. The battery
is fully charged. Proceed to step 11.
Result: One or more battery cells display a
specific 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
specific gravity of each battery cell with a
hydrometer. Note the results.
