Screwdriving
Your tool has a clutch with adjustable torque for driving
and removing a wide array of fastener shapes and sizes. The
numbers on the mode selection collar
6
are used to 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
6
to the desiredposition.
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.
Drilling
1. Turn the mode selection collar
6
to the drillsymbol. Refer
to ModeSelection.
2. Place drill bit in contact with theworkpiece.
NOTE: Use sharp drill bitonly.
3. Pull the trigger 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 (7.9 mm to 12.7 mm) in steel can be made
easier if a pilot hole (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workpiece.
Hammerdrilling

WARNING: Wear proper respiratory protection. Collect
residual dust with a vacuum or dust collection system
designed for the application.
DCD709 Only
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drillingonly.
1. Select the desired speed/torque range using the speed
selector
7
to match the speed and torque to the planned
operation. Turn the mode selection collar
6
to the
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
Your DeWALT power tool has been designed to operate
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: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
dust mask 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 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.
