3.7 BATTERY MAINTENANCE AND CHARGING

Battery Maintenance, Quarterly

1. Open battery compartment cover to allow access to bat-
tery terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELECTROLYTE COV-
ERS PLATES. DO NOT CHARGE BATTERIES UNLESS ELECTROLYTE COVERS THE
PLATES.
NOTE: When adding distilled water to batteries, non-metallic con-
tainers and/or funnels must be used.
To avoid electrolyte overflow, add distilled water to batter-
ies after charging.
When adding water to the battery, fill only to level indi-
cated or 3/8" above separators.
2. Remove all vent caps and inspect electrolyte level of
each cell. Electrolyte level should be to the ring approxi-
mately one inch from top of battery. Fill batteries with
distilled water only. Replace and secure all vent caps.
3. Remove battery cables from each battery post one at a
time, negative first. Clean cables with acid neutralizing
solution (e.g. baking soda and water or ammonia) and
wire brush. Replace cables and/or cable clamp bolts as
required.
4. Clean battery post with wire brush then re-connect
cable to post. Coat non-contact surfaces with mineral
grease or petroleum jelly.
5. When all cables and terminal posts have been cleaned,
ensure all cables are properly positioned and do not get
pinched. Close battery compartment cover.
6. Start hydraulic system and ensure that it functions prop-
erly.

Optional On Board Generator

EXHAUST GAS HAZARD. RUN THE GENERATOR IN A WELL VENTILATED AREA
ONLY.
WHEN THE GENERATOR ENABLE CONTROL LOCATED IN THE PLATFORM CON-
TROL BOX IS IN THE ON POSITION AND THE GROUND EMERGENCY STOP
SWITCH IS ON (PULLED OUT), THE GENERATOR WILL START AUTOMATICALLY
WHEN THE BATTERIES REACH A LOW-CHARGE STATE, AUTOMATICALLY
CHARGING THE BATTERIES. THE GENERATOR WILL ALSO AUTOMATICALLY
START IF THE GENERATOR START BATTERY IS LOW.
NOTE: The engine will automatically shut down under the follow-
ing conditions:
High Engine Oil Temperature
Low Engine Oil Pressure
Engine Overspeed
Generator Overvoltage
Batteries fully charged
TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR ALLOW SPARKS
OR A FLAME NEAR BATTERY DURING SERVICING. ALWAYS WEAR EYE AND
HAND PROTECTION WHEN SERVICING BATTERIES.

Battery Charging (On Board Charger)

1. For maximum battery life:
a. Avoid completely discharging the batteries.
b. Fully charge the batteries each day the machine is
used.
c. Charge the batteries at available times between
charging.
d. Be sure the battery fluid covers the battery plates
before charging, but to avoid overflow, do not top
off the fluid level until charging.
2. To charge the batteries, connect the charger to a 115
volt source with a 15 amp minimum capacity.
3. The Charger will shut off automatically when the batter-
ies are fully charged.
4. The charge cycle is complete when the ammeter reads 0
amps. Any reading indicates the charge cycle is not
complete.
5. Depleted batteries will take approximately 17 hours to
charge.
