Dual Range Gearing (Fig. 1)
The dual range feature of your driver/drill allows you to shift gears for greater versatility.
To select the low speed, high torque setting, turn the tool off and permit to stop. Slide the gear shifter
(D) forward (towards the chuck). To select the high speed, low torque setting, turn the tool off and
permit to stop. Slide the gear shifter back (away from chuck).
NOTE:
Do not change gears when the tool is running. If you are having trouble changing gears,
make sure that the dual range gear shifter is either completely pushed forward or completely
pushed back.
Keyless Single Sleeve Chuck
Your tool features a keyless chuck with one rotating sleeve for one-handed operation of the chuck. To
insert a drill bit or other accessory, follow these steps.
1. Lock the trigger in the OFF position as previously described.
2. Grasp the black sleeve of the chuck with one hand and use the other hand to secure the tool.
Rotate the sleeve counterclockwise far enough to accept the desired accessory.
3. Insert the accessory about 3/4" (19 mm) into the chuck and tighten securely by rotating the chuck
sleeve clockwise with one hand while holding the tool with the other. Your tool is equipped with an
automatic spindle lock mechanism. This allows you to open and close the chuck with one hand.
To release the accessory, repeat step 2 above.
WARNING:
Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of
the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock
off trigger switch when changing acces sories.
Be sure to tighten chuck with one hand on the chuck sleeve and one hand holding the tool for
maximum tightness.
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and remove the
battery pack before making any adjustments or removing/installing attachments or
accessories.
An accidental start-up can cause injury.
Installing and Removing the Battery Pack (Fig. 2)
NOTE:
Make sure your battery pack is fully charged.
To install the battery pack into the tool handle
, align the notch inside the tool’s handle with the
battery pack 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 (E) and firmly pull the
battery pack out of the tool handle. Insert it into the charger as described in the charger section of
this manual.
Drill Operation
WARNING:
To reduce the risk of serious personal injury, turn tool off and disconnect tool from
power source 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 to the drill bit symbol for drilling. Select the desired speed/torque range using the gear
shifter to match the speed and torque to the planned operation.
1. Use sharp drill bits only. For WOOD, use the low speed setting and twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use the low speed setting and steel twist drill bits
or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped
bits. Use low speed for bits greater than 3/8" (10 mm).
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill 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 drill. If model is not equipped
with side handle, grip drill with one hand on the handle and one hand on the battery pack.
CAUTION:
Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the
drill firmly to control the twisting action and avoid injury.
4.
IF DRILL STALLS,
it is usually because it is being overloaded or improperly used.
RELEASE
TRIGGER IMMEDIATELY,
remove drill bit from work, and determine cause of stalling.
DO
NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL —
THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce pressure on drill 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 drilled hole. This will help prevent
jamming.
7. With variable speed drills 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 to drill without the bit skipping out.
Operation as a Screwdriver
Select the desired speed/torque range using the dual range gear shifter on the top of tool to match
the speed and torque to the planned operation.
Insert the desired fastener accessory into the chuck as you would any drill bit. Make a few practice
runs in scrap or unseen areas to determine the proper position of the clutch collar.

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. If 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 Automatic Tune-Up™ mode.
4. Once the Automatic Tune-Up™ mode is complete, the charger will begin a maintenance
charge; the red indicator will remain lit.
Chargers
Your tool uses a D
E
WALT charger. Be sure to read all safety instructions before using your charger.
Consult the chart at the end of this manual for compatibility of chargers and battery packs.
Charging Procedure (Fig. 3)
DANGER:
Electrocution hazard. 120 volts are present at charging terminals. Do not probe with
conductive objects. Electric shock or electrocution may result.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into the charger, as shown in Figure 3, 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.
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 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 +104 °F (+40°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. 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, 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.
WARNING:
Burn hazard. 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. For long storage, it is recommended to store a fully charged battery pack in a cool dry place
out of the charger for optimal results.
NOTE:
Battery packs should not be stored completely depleted of charge. The battery pack will
need to be recharged before use.
