Chargers
Your tool uses a D WALT Charger. Your battery can be
E
charged in D WALT 1 Hour Chargers, 15 Minute Chargers
E E
or Vehicular 12 volt charger. Be sure to read all safety
instructions before using your charger. Consult the chart on
the back cover of this manual for compatibility of chargers
and battery packs.

15 MINUTE CHARGER
Charging Procedure
DANGER: Electrocution hazard. 120 volts are present at
charging terminals. Do not probe with conductive objects.
1. Plug the charger into an appropriate outlet before
inserting battery pack.
2. Insert the battery pack into the charger. The red
(charging) light will blink continuously indicating that
the charging process has started (Fig. 2).
3. The completion of charge will be indicated by the red light
remaining ON continuously. The pack is fully charged and
may be used at this time or left in the charger.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that
can arise with battery packs. Problems are indicated by the
red light flashing at a fast rate. If this occurs, re-insert battery
pack into the charger. If the problem persists, try a different
battery pack to determine if the charger is OK. If the new
pack charges correctly, then the original pack is defective
and should be returned to a service center or other collection
site for recycling. If the new battery pack elicits the same
trouble indication as the original, have the charger tested at
an authorized service center.

HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when
the charger detects a battery that is hot, it automatically
starts a Hot Pack Delay, suspending charging until the bat-
tery has cooled. After the battery has cooled, the charger
automatically switches to the Pack Charging mode. This fea-
ture ensures maximum battery life. The red light flashes
long, then short while in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When
the charger is used with some portable power sources such
as generators or sources that convert DC to AC, the charger
may temporarily suspend operation, flashing the red light
with two fast blinks followed by a pause. This indicates
the power source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the
red light glowing indefinitely. The charger will keep the bat-
tery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept
out of the charger. If the battery pack has not been kept on
maintenance charge, it may need to be recharged before
1 HOUR CHARGER
use. A battery pack may also slowly lose its charge if left in
a charger that is not plugged into an appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a
weak battery. Such batteries are still usable but should not
be expected to perform as much work. In such cases, about
10 seconds after battery insertion, the charger will beep
rapidly 8 times to indicate a weak battery condition. The
charger will then go on to charge the battery to the highest
capacity possible.
Important Charging Notes
1. Longest life and best performance can be obtained if the
battery pack is charged when the air temperature is
between 65°F and 75°F (18°- 24°C). DO NOT charge
the battery pack in an air temperature below +40°F
(+4.5°C), or above +105°F (+40.5°C). This is important
and will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to
touch while charging. This is a normal condition, and
does not indicate a problem.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or
other appliance
b. Check to see if receptacle is connected to a light
switch which turns power off when you turn out the
lights.
c. Move charger and battery pack to a location where
the surrounding air temperature is approximately
65°F - 75°F (18° - 24°C).
d. If charging problems persist, take the tool, battery
pack and charger to your local service center.
4. The battery pack should be recharged when it fails to
produce sufficient power on jobs which were easily done
previously. DO NOT CONTINUE to use under these
conditions. Follow the charging procedure. You may also
charge a partially used pack whenever you desire with
no adverse affect on the battery pack.
5. Under certain conditions, with the charger plugged into
the power supply, the exposed charging contacts inside
the charger can be shorted by foreign material. Foreign
materials of a conductive nature such as, but not limited
to, steel wool, aluminum foil, or any buildup of metallic
particles should be kept away from charger cavities.
Always unplug the charger from the power supply when
there is no battery pack in the cavity. Unplug charger
before attempting to clean.
6. Do not freeze or immerse charger in water or any other
liquid.
WARNING: Shock hazard. Don't allow any liquid to get
inside charger.
CAUTION: Never attempt to open the battery pack for any
reason. If the plastic housing of the battery pack breaks or
cracks, return to a service center for recycling.
Installing and Removing the
Battery Pack
CAUTION: Engage contact trip lock-off before removing
or installing battery.
FIG. 3
NOTE: Make sure your battery pack is fully charged.
To install the battery pack into the tool handle, align the
base of the tool with the notch inside the tool's handle and
slide the battery pack firmly into the handle until you hear the
lock snap into place.
To remove the battery pack from the tool, press the
release buttons (M) and firmly pull the battery pack out of the
tool handle. Insert it into the charger as described in the
charger manual (Fig. 4).
