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 D
e
WALT 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.
