•
Make sure that cord is located so that it will not be stepped on, tripped over, or oth-
erwise subjected to damage or stress.
•
Do not use an extension cord unless it is absolutely necessary.
Use of improper exten-
sion cord could result in risk of fire, electric shock, or electrocution.
•
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. When using more than one extension to
make up the total length, be sure each individual extension contains at least the minimum
wire size.

Volts). Do not attempt to use it on any other voltage.
This does not apply to the vehic-
ular charger.
Using Automatic Tune-Up™ Mode
The Automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10
charge/discharge cycles or whenever the pack no longer delivers the same amount of work.
To use the Automatic Tune-Up™, place the battery pack in the charger and leave it for at least
8 hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no
longer blink. This indicates that the pack is fully charged and can be used at this time.
3. Whenever the pack is left in the charger after the initial 1-hour charge, the charger will begin
the Automatic Tune-Up™ Mode. This mode continues up to 8 hours or until the individual
cells in the battery pack are equalized. The battery pack is ready for use and can be
removed at any time during the Tune-Up™ Mode.
4. Once the Automatic Tune-Up™ Mode is complete the charger will transition to a main-
tenance charge; the indicator light shuts off when the Automatic Tune-Up™ Mode is
complete.
SAVE THESE INSTRUCTIONS
FOR FUTURE USE
Chargers
Your tool uses an 9.6-18 Volt D
E
WALT Charger. Your battery can be charged in D
E
WALT 1
Hour Chargers, 15 Minute Chargers 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.
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 (Fig. 1). The red (charging) light will blink continu-
ously 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.
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 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 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 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. 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 condi-
tion. 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 nor-
mal 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 serv-
ice 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 charg-
er 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. Do not 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
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 (Fig. 2) and slide the battery pack firmly into the handle until you hear
the lock snap into place (Fig. 3).
To remove the battery pack from the tool
, press the release buttons (A) and firmly pull
the battery pack out of the tool handle. Insert it into the charger as described in the charger
manual.
OPERATION
Switch - DW059 (Fig. 4)
Pressing the BOTTOM part of the rocker switch (B) runs the tool in forward (right hand thread)
direction. Pressing the TOP of the switch reverses motor direction. This allows “rocking”
fasteners to break them loose.
Variable Speed Trigger Switch (Fig. 4)
To turn the tool on, squeeze the trigger switch. To turn the tool off, release the trigger switch.
Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully
released. The variable speed switch enables you to select the best speed for a particular appli-
cation. The more you squeeze the trigger, the faster the tool will operate. Use lower speeds for
starting holes without a center punch, drilling in metals or plastics, or driving screws. For max-
imum tool life, use variable speed only for starting holes or fasteners.
NOTE:
Continuous use in variable speed range is not recommended. It may damage the
switch and should be avoided.
Forward/Reverse Control Button (Fig. 4)
A forward/reverse control button determines the direction of the tool and also serves as a lock
off button.
To select forward rotation,
release the trigger switch and depress the
forward/reverse control button on the right side of the tool.
To select reverse,
depress the for-
ward/reverse control button on the left side of the tool. The center position of the control button
locks the tool in the OFF position. When changing the position of the control button, be sure the
trigger is released.
NOTE:
The first time the tool is run after changing the direction of rotation, you may hear a
click on start up. This is normal and does not indicate a problem.
Quick Release Chuck – DW050, DW052, DW054, DW056
(Fig. 5)
NOTE:
The chuck accepts 1/4" (6.35 mm) hex accessories only.
Place the switch in the locked off (center) position or remove battery pack before changing
accessories.
To install an accessory
, pull the chuck collar away from the front of the tool, insert the acces-
sory, and release the collar. The accessory is locked in place.
To remove an accessory
, pull the chuck collar away from the front of the tool. Remove the
accessory and release the collar.
Anvil With Detent Pin – DW053, DW055, DW057, DW059
(Fig. 6)
Place the switch in the locked off (center) position or remove battery pack before changing
accessories.
To install a socket on the anvil,
align the hole in the side of the socket with the detent pin
(C) on the anvil (D). Press the socket on until the detent pin engages in the hole. Depression
of detent pin may be necessary to aid installation of socket.
CAUTION:
Use only impact sockets. Non-impact sockets may break and cause a haz-
ardous condition. Inspect sockets prior to use to ensure that it contains no cracks.
To remove a socket,
depress the detent pin through the hole, using a small pointed object,
and pull the socket off.

CAUTION:
Ensure fastener and/or system will withstand the level of torque generated by
the tool. Excessive torque may cause breakage and possible personal injury.
1. Place the socket on the fastener head. Keep the tool pointed straight at the fastener.
2. Press rocker switch to start operation. Always check torque with a torque wrench, as the
fastening torque is affected by many factors including the following:
•
Voltage:
Low voltage, due to a nearly discharged battery, will reduce fastening torque.
•
Socket size:
Failure to use the correct socket size will cause a reduction in fastening
torque.
•
Bolt Size:
Larger bolt diameters generally require higher fastening torque. Fastening
torque will also vary according to length, grade, and torque coefficient.
•
Bolt:
Ensure that all threads are free of rust and other debris to allow proper fastening
torque
•
Material:
The type of material and surface finish of the material will affect fastening
torque.
•
Fastening Time:
Longer fastening time results in increased fastening torque. Using a
longer fastening time than recommended could cause the fasteners to be overstressed,
stripped or damaged.
MAINTENANCE
Cleaning
CAUTION:
Blow dirt and dust out of all air vents with dry air at least once a week. Wear safe-
ty glasses when performing this procedure. Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with water and mild soap. Do not use gaso-
line, turpentine, lacquer or paint thinner, dry cleaning fluids or similar products. Never let any
liquid get inside the tool; never immerse any part of the tool into a liquid.
CHARGER CLEANING INSTRUCTIONS
