CHARGING THE BATTERY
BATTERY HAZARDS
Always read and comply with the bat-
tery manufacturer’s recommenda-
tions for procedures concerning
proper battery use and maintenance.
Batteries contain sulfuric acid and
generate explosive mixtures of hy-
drogen and oxygen gases. Keep any
device that may cause sparks or
flames away from the battery to pre-
vent explosion.
Always wear protective glasses or
goggles and protective clothing
when working with batteries. You
must follow the battery manufac-
turer’s instructions on safety, mainte-
nance and installation procedures.
There are three types of batteries:
•
Lead acid (requires maintenance)
•
Lead acid (maintenance-free)
•
Lithium (maintenance-free)
To charge a maintenance-free battery:
1.
Do not use an external charger.
2.
Charge using the correct AC input voltage indicated
on the battery’s label.
3.
Avoid charging the battery in direct sunlight.
Also follow these additional requirements:
1.
Make sure the battery is connected to the machine
before charging.
2.
Connect the battery charger to a grounded AC
circuit.
3.
Charge the battery as needed after use.
To charge a lead-acid (requires maintenance)
battery:
1.
Do not use an external charger.
2.
Charge the battery in a well-ventilated area.
3.
Charge the battery using the correct AC input volt-
age indicated on the battery’s label.
4.
Avoid charging the battery in direct sunlight.
Also follow these additional requirements:
1.
Make sure the battery is connected to the machine
before charging.
2.
Remove the ventilation cover of the lead-acid
battery.
3.
Check the acidic liquid level of the lead-acid battery.
If needed, refill the distilled water through a filling
line above the lead-acid battery. Only add enough
distilled water to cover the plate. Never overfill dur-
ing charging.
4.
Install the ventilation cover.
5.
Connect the lead-acid battery charger to the
grounded AC circuit.
6.
The charger indicates when the lead-acid battery is
fully charged.
7.
Check the acid level of the lead-acid battery at the
end of the charging cycle. Add distilled water to the
bottom of the tube. Never overfill the tube at the end
of the charging cycle.
