CHARGING A BATTERY PACK
If the charger does not charge the battery pack under normal
circumstances, take both the battery pack and charger to your
nearest Authorized Service Center for electrical check.
 Use battery pack only with the recommended charger.
 Connect the charger to the power supply. Make sure the
power supply is normal household voltage, 120 volts,
AC only, 60 Hz.
 Make sure the latches on each side of the battery pack
snap into place and the battery pack is secured in the
charger before beginning operation.
 Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
 Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
 Do not place the charger and battery pack(s) in an area
of extreme heat or cold. They will work best at normal
room temperature.
NOTE: The charger and battery pack(s) should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
 The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
 After charging is complete, the green LED will remain
on until the battery pack is removed from the charger or
charger is disconnected from the power supply or until
charger enters maintenance mode/energy save mode.
 To remove the battery pack(s) from the charger, depress
the latches on each side of the battery pack.
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 122°F,
the charger will automatically begin fast charge mode.
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
32°F, the charger will automatically begin charge mode.
COLD WEATHER OPERATION
The lithium-ion battery pack can be used in temperatures
down to -4°F. 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 up and begin operating normally.
