WARNING:
Do not allow familiarity with the hammer drill to make
you careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
CHARGING BATTERY PACK
The battery pack for this tool has been shipped in a low
charge condition to prevent possible problems. Therefore,
you should charge it until the light on front of charger changes
from flashing green to continuous green.
Note: Batteries will not reach full charge the first time they
are charged. Allow several cycles (drilling followed by
recharging) for them to become fully charged. This is normal
for nickel-cadmium batteries.
TO CHARGE
■ Charge battery pack only with the charger provided.
■ Make sure power supply is normal house voltage, 120
volts, 60 Hz, AC only.
■ Connect the charger to a power supply.
■ Attach battery pack to charger by aligning raised ribs on
battery pack with grooves in charger, then slide battery
pack onto charger. See Figure 2.
■ After normal usage, 30 minutes of charging time is required to
be fully charged.
■ The battery pack will become slightly warm to the touch while
charging. This is normal and does not indicate a problem.
■ Do not place charger in an area of extreme heat or cold. It
will work best at normal room temperature.
■ When the batteries become fully charged, unplug your
charger from power supply and remove the battery pack.
IMPORTANT INFORMATION FOR RECHARG-
ING HOT BATTER
Y PACK
When using this drill continuously, the batteries in the
battery pack will become hot. The battery pack for this tool
will charge more rapidly and efficiently when at a cooled
temperature.
The internal fan for this charger will automatically turn on
when a hot battery pack is inserted. Air circulates through
the battery, bringing it to optimum charging temperature,
decreasing the time required to begin fast charging the
pack, and extending the life of the battery.
When the battery pack becomes discharged and is hot, the
green LED will be off and the red LED will begin flashing.
When the battery pack cools down to approximately 104°F
(40°C), the charger will automatically begin fast charge
mode.
If the Red LED continues to flash for more than 90 minutes,
and the green LED remains off, this may indicate a dam-
aged battery that will not charge.

IMPORTANT INFORMATION FOR RECHARG-
ING COOL BATTERY PACK
If 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 41°F

Note: Refer to "CHARGING BATTERY PACK" for normal
recharging of batteries. If the charger does not charge your
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.
KEEPING THE CHARGER VENTS CLEAN
The fan in this charger will perform more efficiently if the air
vents and ports are kept free of dust or other debris. Peri-
odically check the air vents, and using a fine brush, whisk
dust or debris away from the air vents and ports.
CAUTION:
To prevent damage to battery pack, remove battery
pack from charger immediately if no LED comes
on. Return battery pack and charger to your near-
est service center for checking or replacing. Also, if
you are removing battery pack from charger and no
LEDs are on, return both battery pack and charger
to your nearest service center. Do not insert an-
other battery pack into charger. A damaged charger
may damage a battery pack.
