3.10 BATTERY MAINTENANCE AND
CHARGING
IF REPLACING A BATTERY, EACH NEW BATTERY MUST WEIGH
AT LEAST 115 POUNDS (52 KG). FAILURE TO REPLACE THE BAT-
TERY WITH ONE OF THE CORRECT WEIGHT WILL RESULT IN A
TIPOVER HAZARD WHICH COULD RESULT IN SERIOUS INJURY
OR DEATH.
Battery Maintenance, Quarterly
1. Open battery compartment cover to allow access to
battery terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELEC-
TROLYTE COVERS PLATES. DO NOT CHARGE BATTERIES UNLESS
ELECTROLYTE COVERS THE PLATES.
NOTE: When adding distilled water to batteries, non-metallic
containers and/or funnels must be used.
To avoid electrolyte overflow, add distilled water to
batteries after charging.
When adding water to the battery, fill only to level
indicated or 3/8" above separators.
2. Remove all vent caps and inspect electrolyte level of
each cell. Electrolyte level should be to the ring
approximately one inch from top of battery. Fill bat-
teries 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 neu-
tralizing 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 min-
eral 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
properly.
Optional On Board Generator
EXHAUST GAS HAZARD. RUN THE GENERATOR IN A WELL VEN-
TILATED AREA ONLY.
WHEN THE GENERATOR ENABLE CONTROL LOCATED IN THE
PLATFORM CONTROL BOX IS IN THE ON POSITION AND THE
GROUND EMERGENCY STOP SWITCH IN ON (PULLED OUT), THE
GENERATOR WILL START AUTOMATICALLY WHEN THE BATTER-
IES REACH A LOW-CHARGE STATE AUTOMATICALLY CHARGING
THE BATTERIES.
NOTE: The engine will automatically shut down under the
following conditions:
Charged Batteries
High Engine Oil Temperature
Low Engine Oil Pressure
Engine Overspeed
Generator Overvoltage
TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR
ALLOW SPARKS OR A FLAME NEAR BATTERY DURING SERVIC-
ING. ALWAYS WEAR EYE AND HAND PROTECTION WHEN SER-
VICING 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 charge cycle is complete when the 100% LED is
lit. Any other reading indicates the charge cycle is
not complete.
4. The Charger will shut off automatically when the bat-
teries are fully charged.
Depleted batteries will take approximately 23 hours to
charge.
