A forward/reverse control button
rotational direction of the tool and also serves as a
lock‑off button.
• To select forward rotation (clockwise), release the trigger
and depress the forward/reverse control button on the right
side of the tool.
• To select reverse (counterclockwise), depress the forward/
reverse control button on the left side of the tool.
NOTE: 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: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.
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.
Worklight (Fig. A)
The worklight
is activated when the trigger switch is
7
depressed, and will automatically turn off 20 seconds after
the trigger switch is released. If the trigger switch remains
depressed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.
Performing an Application (Fig. A)
WARNING: To reduce the risk of personal injury,
ALWAYS ensure workpiece is anchored or clamped firmly.
WARNING: Always wait until the motor has come to a
complete standstill before changing the direction of rotation.
Prior to Performing Work
• Set the speed selector
6
• Install the appropriate bit or accessory into the chuck.
Refer to Installing a Bit or Accessory into a Keyless Chuck.
WARNING:
• Do not use this tool to mix or pump easily combustible or
explosive fluids (benzine, alcohol, etc.).
• Do not mix or stir flammable liquids labeled accordingly.
Screwdriving
Your tool has a clutch with adjustable torque for driving
and removing a wide array of fastener shapes and sizes. The
numbers 1–15 on the mode selection collar
set a torque range for screwdriving. The higher the number
on the collar, the higher the torque and the larger the
fastener which can be driven.
1. Turn the mode selection collar
Refer to Mode Selection.
2. Pull the trigger switch applying pressure in a straight line
with the bit until the fastener is seated at the desired depth
in the workpiece.
Recommendations for Screwdriving
• Start with lower torque settings, then advance to
higher torque settings to avoid damage to the workpiece
or fastener.
• Make some practice runs in scrap or on unseen areas
of the workpiece to determine the proper position of the
mode selection collar.

2. Place drill bit in contact with the workpiece.
NOTE: Use sharp drill bit only.
3. Pull the trigger switch applying pressure in a straight line
with the bit until it reaches the desired depth.
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.
4. Keep the motor running when pulling the bit back out of
a drilled hole to prevent jamming.
Recommendations for Drilling
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect the bit.
• IF THE DRIll STAllS:
- RElEASE TRIGGER SWITCH IMMEDIATElY, remove drill
bit from work, and determine cause of stalling.
- DO NOT DEPRESS TRIGGER SWITCH ON AND OFF IN
AN ATTEMPT TO START A STAllED DRIll—THIS CAN
DAMAGE THE DRIll.
- To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of the hole.
• Large holes (5/16" to 1/2" [7.9 mm to 12.7 mm]) in steel
can be made easier if a pilot hole (5/32" to 3/16" [4 mm to
4.8 mm]) is drilled first.
• If drilling thin material or material that is prone to
splinter, use a wood "back‑up" block to prevent damage to
the workpiece.
Hammerdrilling
IMPORTANT: Use carbide‑tipped or masonry bits rated for
percussion drilling only.
1. Select the desired speed/torque range using the
speed selector
6
to match the speed and torque to the
planned operation. Turn the mode selection collar
hammerdrill symbol.
2. Pull the trigger, applying just enough pressure on the
hammer to keep it from bouncing excessively or "rising" off
the bit.
Recommendations for Hammerdrilling
• Too much force will cause slower drilling speeds,
overheating, and a lower drilling rate.
• A smooth even flow of material indicates the proper
drilling rate.
• 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.
• 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.
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.
