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
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.
Hammerdrilling
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.
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
7
. Refer to Speed Selection.
• 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 (1–15)
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
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 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workpiece.
