MAINTENANCE
BATTERIES
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
The lifetime of the batteries depends on their
proper maintenance. To get the most life from the
batteries;
FLOODED (WET) LEAD-ACID BATTERIES
–
Do not leave the battery partially discharged
for long period of time.
– For best charging performance, charge the
battery pack in temperatures below 80°F/27°C
and above 32F°/0°C
–
Maintain the proper electrolyte levels of the
flooded (wet) battery by checking levels
weekly.
The following steps do not apply if Opportunity
charging (See
OPPORTUNITY CHARGING
section.
– Do not charge the battery more than once a
day and only after running the machine for a
minimum of 15 minutes.
– Allow the charger to completely charge the
battery before re using the machine.
CHECKING THE ELECTROLYTE LEVEL
The flooded (wet) lead-acid batteries require
routine watering as described below. Check the
battery electrolyte level weekly.
NOTE:
Do Not
check the electrolyte level if the
machine is equipped with a battery watering
system.

FOR SAFETY: When servicing machine, keep
all metal objects off batteries. Avoid contact
with battery acid.
The electrolyte level should be slightly above the
battery plates as shown before charging. Add
distilled water if low. DO NOT OVERFILL. The
electrolyte will expand and may overflow when
charging. After charging, distilled water can be
added up to about 3 mm (0.12 in) below the sight
tubes.
Before Charging
After Charging
NOTE: Make sure the battery caps are in place
while charging. There may be a sulfur smell after
charging batteries. This is normal.
CHECKING CONNECTIONS / CLEANING
After every 200 hours of use check for loose
battery connections and clean the surface of the
batteries, including terminals and cable clamps,
with a strong solution of baking soda and water.
Replace any worn or damaged wires. Do not
remove battery caps when cleaning batteries.
