OPERATION
TO CHARGE
A fully discharged battery pack with a temperature between
32°F (0°C) and 150°F (65°C) will charge in about an hour.
Charge the 24 Volt lithium-ion battery pack only with the
charger provided.
� Connect the charger to a power supply.
NOTE:
i
If needed
,
the charger can operate with most
generators and inverters rated at 300 Watts or higher.
Attach the battery pack to the charger by aligning the
raised ribs on the battery pack with the grooves in the
charger, then slide the battery pack onto the charger. See
Figure 4.
Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.
After charging is complete, the continuous green light
will come on and the charge level indicator lights on the
battery will go off.
The charger will keep the battery pack fully charged if left
on the charger.
CHARGING A HOT BATTERY PACK
If the battery pack is above normal temperature range, the
red LED will begin flashing and the green LED will be off.
When the battery pack cools down to approximately 150°F
(65°C), the charger will automatically begin fast charge mode.
NOTE: Refer to CHARGING THE BATTERY PACK for
normal recharging of batteries. If the charger does not charge
the battery pack under normal circumstances, return both
the battery pack and charger to your nearest repair center
for electrical check. For the location of your nearest repair
center, please call 1-866-539-1710.
CHARGING A COOL BATTERY PACK
If the battery pack is below normal temperature range, the
red LED will begin flashing and the green LED will be off.
When the battery warms to a temperature of more than 14°F
(-10°C), the charger will automatically begin charging.
COLD WEATHER OPERATION
The lithium-ion battery pack can be used in temperatures
down to -4°F (-20°C). When the battery pack is very cold, it
may “buzz” for the first minute of use to warm itself up. Put
the battery pack on a tool and use the tool in a light duty
application. After about a minute, the pack will have warmed
itself up and begin operating normally.
