• An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that
is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. When using more than one extension to
make up the total length, be sure each individual extension contains at least the minimum
wire size. The following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

• Do not place any object on top of charger or place the charger on a soft surface
that might block the ventilation slots and result in excessive internal heat. Place the
charger in a position away from any heat source. The charger is ventilated through slots in
the top and the bottom of the housing.
• Do not operate charger with damaged cord or plug.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way. Take it to an authorized service center.
• Do not disassemble charger; take it to an authorized service center when service or
repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution
or fire.
• Disconnect the charger from the outlet before attempting any cleaning. This will
reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard 120V household electrical power. Do
not attempt to use it on any other voltage. This does not apply to the vehicular charger.
Chargers
Your tool uses a D
WALT charger. Be sure to read all safety instructions before using your
E
charger. Consult the chart on the back cover of this manual for compatibility of chargers and
battery packs.
Charging Procedure (Fig. 2)
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack (F) into the charger, as shown in Figure 2, making sure the pack
is fully seated in charger. The red (charging) light will blink continuously indicating that the
charging process has started.
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.
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 battery has cooled.
After the battery has cooled, the charger automatically switches to the Pack Charging mode.
This feature ensures maximum battery life. The red light flashes long, then short while in the
Hot/Cold Pack Delay mode.
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 battery 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 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 pack. Such batteries are
still usable but should not be expected to perform as much work. The charger will indicate to
replace battery pack.
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. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm environment such as in a metal
shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check operation of 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. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal
chips, 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. Electric shock may
result.
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.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunlight and excess
heat or cold.
2. Long storage will not harm the battery pack or charger. Under proper conditions, they can
be stored for 5 years or more.

activated when the trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work surface and is not intended to be
used as a flashlight.
Torque Adjustment Collar (Fig. 1)
The torque adjustment collar (C) is clearly marked with numbers and the max position.The
collar should be rotated until the desired setting is located at the top of the tool (Fig. 1). Locators
are provided in the collar to eliminate the guess work when selecting fastening torque. The
higher the number on the collar, the higher the torque and the larger the fastener which can be
driven. To lock the clutch for drilling operations, move to the max position.
Quick-Release Chuck (Fig. 1, 4)
NOTE: The chuck accepts 1/4" (6.35mm) hex accessories and 1" (25.4 mm) bit tips only.
Place the forward/reverse button (B) in the locked off (center) position or remove battery
pack before changing accessories.

Drilling Mode
WARNING: To reduce the risk of serious personal injury, place the forward/reverse
button in the lock-off position or turn tool off and disconnect battery pack before
making any adjustments or removing/installing attachments or accessories.
WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is
anchored or clamped firmly. If drilling thin material, use a wood "back-up" block to prevent
damage to the material.
Turn the collar (C) to the max position symbol for drilling.
1. Use hex shank drill bits only.
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep the
bit biting, but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the tool.
WARNING: The screwdriver may stall if overloaded causing a sudden twist. Always
expect the stall. Grip the screwdriver firmly with both hands to control the twisting action
and avoid injury.
4. IF THE SCREWDRIVER STALLS, it is usually because it is being overloaded or
improperly used. RELEASE TRIGGER IMMEDIATELY, remove bit from work, and
determine the cause of stalling. DO NOT CLICK TRIGGER ON AND OFF IN AN
ATTEMPT TO START A STALLED SCREWDRIVER — THIS CAN DAMAGE THE
SCREWDRIVER.
5. To minimize stalling or breaking through the material, reduce pressure on the screwdriver
and ease the bit through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a hole. This will help prevent
jamming.
7. With variable speed screwdrivers, there is no need to center punch the point to be
drilled. Use a slow speed to start the hole and accelerate by squeezing the trigger
harder when the hole is deep enough without the bit skipping out.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, place the forward/reverse
button in the lock-off position or turn tool off and disconnect battery pack before
making any adjustments or removing/installing attachments or accessories.
