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. Use sharp drill bits only. For WOOD, use the
low speed setting and twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use
the low speed setting and steel twist drill bits or
hole saws.
2. Always apply pressure in a straight line with the
bit. Use enough pressure to keep drill biting, but
do not push hard enough to stall the motor or
deflect the bit.
3. Hold tool firmly with both hands to control the
twisting action of the drill.
CAUTION: 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. IF DRILL STALLS, it is usually because
it is being overloaded or improperly used.
RELEASE TRIGGER IMMEDIATELY, remove
drill bit from work, and determine cause of
stalling. DO NOT CLICK TRIGGER ON
AND OFF IN AN ATTEMPT TO START A
STALLED DRILL — THIS CAN DAMAGE
THE DRILL.
5. To minimize stalling or breaking through the
material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
6. Keep the motor running when pulling the bit
back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to
center punch the point to be drilled. Use a
slow speed to start the hole and accelerate by
squeezing the trigger harder when the hole is
deep enough to drill without the bit skipping
out.
DRILLING IN METAL
Start drilling with slow speed and increase to full
power while applying firm pressure on the tool.
A smooth even flow of metal chips indicates the
proper drilling rate. Use a cutting lubricant when
drilling metals. The exceptions are cast iron and
brass which should be drilled dry.
NOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes
in steel can be made easier if a pilot hole [5/32"
(4 mm) to 3/16" (5 mm)] is drilled first.
DRILLING IN WOOD
Start drilling with slow speed and increase to full
power while applying firm pressure on the tool.
Holes in wood can be made with the same twist
drills used for metal. These bits may overheat unless
pulled out frequently to clear chips from the flutes.
Work that is apt to splinter should be backed up
with a block of wood.
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
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing
set-ups or when making repairs.
Be sure the trigger switch is in the OFF
position. An accidental start-up can
cause injury.
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.
