Screwdriving (Fig. E)
1. Select the desired speed/torque range using the gear
shifter
to match the speed and torque to the
6
planned operation.
2. Turn the torque adjustment collar
desired position.
nOTE: Use the lowest torque setting required to
seat the fastener at the desired depth. The lower the
number, the lower the torque output.
3. Insert the desired fastener accessory into the chuck as
you would any drill bit.
4. Make some practice runs in scrap or on unseen areas of
the workpiece to determine the proper position of the
torque adjustment collar.
5. Always start with lower torque settings, then advance
to higher torque settings to avoid damage to the
workpiece or fastener.
nOTE: When torque is achieved in screwdriving mode, the
unit will automatically shut off with a set of short pulses.
Drilling (Fig. D)
NOTICE: If drilling thin material, use a wood "back-
up" block to prevent damage to the material.
1. Select the desired speed/torque range using the gear
shifter
6
to match the speed and torque to the planned
operation. Turn the collar
2. Use sharp drill bits only. For MASONRY, such as brick,
cement, cinder block, etc., use carbide-tipped bits rated
for percussion drilling.
3. 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.
4. 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.
WARNING: 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.
5. 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 depress TRIGGER
ON AND OFF IN AN ATTEMPT TO START A STALLED
DRILL — THIS CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.
7. Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.

Hammerdrilling (Fig. E)
1. Select the desired speed/torque range using the gear
shifter
to match the speed and torque to the planned
6
operation. Turn the collar
iMPORTAnT: Use carbide-tipped or masonry bits rated
for percussion drilling only.
2. Drill with just enough force on the hammer to keep
it from bouncing excessively or "rising" off the bit.
Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
3. Drill straight, keeping the bit at a right angle to the work.
Do not exert side pressure on the bit when drillling as
this will cause clogging of the bit flutes and a slower
drilling speed.
4. When drilling deep holes, if the hammer speed starts to
drop off, pull the bit partially out of the hole with tool
still running to help clear debris from the hole.
nOTE: A smooth, even flow of dust from the hole indicates
proper drilling rate.

MAINTENANCE
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can cause injury.
Your D
WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regular cleaning.
Cleaning
WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this procedure.
WARNING: 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. Never let any liquid
get inside the tool; never immerse any part of the tool
into a liquid.
Charger Cleaning Instructions
WARNING: Shock hazard. Disconnect the charger
from the AC outlet before cleaning. Dirt and grease
may be removed from the exterior of the charger using
a cloth or soft non-metallic brush. Do not use water or
any cleaning solutions.
