while holding the tool with the other hand. Continue to rotate
the chuck sleeve until several ratchet clicks are heard to ensure
full gripping power.
nOTE: Be sure to tighten chuck with one hand on the chuck
sleeve and one hand holding the tool for maximum tightness.
To release the accessory, repeat steps 1 and 2 above.
OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect battery pack before making
any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.
Check for damage to the tool, parts or accessories which may
have occurred during transport.
Proper Hand Position (Fig. D)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a sudden reaction.
Proper hand position requires one hand on the main
handle , with the other hand on the side handle

shifter to speed 2 or 3. This ensures effective control over the
fastener, allowing the screw to be seated correctly and set to
specification. Speed 1 will provide the same clutching torque
as speeds 2 and 3. However, for optimum performance of the
electronic clutch, speeds 2 and 3 are preferred.
nOTE: Use the lowest torque setting (1) first and increase
the number through to the highest setting (11) to seat the
fastener at the desired depth. The lower the number, the
lower the torque output.
2. Reset the torque adjustment collar
number setting for the torque desired. Make a few practice runs
in scrap or unseen areas to determine the proper position of the
torque adjustment collar.
nOTE: The torque adjustment collar may be set to any number
at any time.
Drill Operation (Fig. A)

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.
1. Select the desired speed/torque range using the
gear shifter 8 to match the speed and torque to the
planned operation.
2. For WOOD, use twist bits, spade bits, power auger bits or
hole saws. For METAL, use high-speed steel twist drill bits or
hole saws. Use a cutting lubricant when drilling metals. The
exceptions are cast iron and brass, which should be drilled dry.

3. Always apply pressure in a straight line with the bit. Use
enough pressure to keep the drill bit 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.
5. IF DRILL sTaLLs, it is usually because it is being overloaded.

6. Keep the motor running when pulling the bit back out of a
drilled hole. This will help prevent jamming.
Hammerdrill Operation (Fig. A)
1. Select the desired speed/torque range using the speed
selector 8 to match the speed and torque to the planned
operation. Set the torque adjustment collar

2. Select the high speed (3) setting by sliding the speed
selector back (away from the chuck).
3. When drilling, use just enough force on the hammer to
keep it from bouncing excessively. Prolonged and too much
force on the hammer will cause slower drilling speeds and
potential overheating.
to
4. Drill straight, keeping the bit at a right angle to the work. Do
not exert side pressure on the bit when drilling, as this will cause
clogging of the bit flutes and a slower drilling speed.
5. When drilling deep holes, if the hammer speed starts to drop
off, pull the bit partially out of the hole with the tool still running
to help clear debris from the hole.
6. For masonry, use carbide-tipped bits or masonry bits. A
smooth, even flow of dust indicates the proper drilling rate.
MAINTENANCE
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.

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.
The charger and battery pack are not serviceable.
Lubrication
Your power tool requires no additional lubrication.
Cleaning

WARNING: Electrical shock and mechanical hazard.
Disconnect the electrical appliance from the power source
before cleaning.

WARNING: To ensure safe and efficient operation, always
keep the electrical appliance and the ventilation slots clean.

WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the 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.
Ventilation slots can be cleaned using a dry, soft non-metallic
brush and/or a suitable vacuum cleaner. Do not use water or
