Checklist B Procedures
8 Perform an equalizing charge OR fully charge
the battery(s) and allow the battery(s) 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 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 a specific
gravity of 1.277 or greater. The battery is fully
charged. Proceed to step 11.
Result: One or more battery cells display a
specific gravity from 1.218 to 1.269. The
battery is still usable, but at a lower
performance. The battery 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 it's 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 less
than 1.177. Replace the battery.
11 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.
12 Install the vent caps and neutralize any
electrolyte that may have spilled.
13 Install the cover for the auxiliary power unit
batteries.

Inspect the Electrical Wiring

Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
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.
1 Remove the engine pivot plate retaining
fastener. Swing the engine pivot plate out
away from the machine.

Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
