supply. Failure to do so will cause the tool to start
immediately the next time it is plugged in. Damage
or injury could result.
Chuck
To insert bit, open chuck jaws by turning collar with
fingers and insert shank of bit about 3/4” (19mm)
into chuck. Tighten chuck collar by hand. Place
chuck key in each of the three holes and tighten in
clockwise direction. It’s important to tighten chuck
with all three holes.
To release bit, turn chuck key counterclockwise in
just one hole, then loosen the chuck by hand.
Chuck Removal (Fig. 3, 4)
1. Place chuck key in chuck as shown in Figure
3. Using a wooden mallet or similar object,
strike key sharply in a CLOCKWISE direction.
This willloosen screw inside chuck.
2. Open chuck jaws fully. Insert screwdriver into
front of chuck between jaws to engage screw
head. Remove screw by turning clockwise (left-
hand thread).
3. Place key in chuck as shown in Figure 4. Using
a wooden mallet or similar object, strike key
sharply in a COUNTERCLOCKWISE direction.
This will loosen chuck so that it can be
unscrewed by hand.
OPERATION
WARNING: To reduce the risk of
injury, turn unit off and disconnect
it from power source before
installing and removing accessories,
before adjusting or when making
repairs. An accidental start-up can
cause injury.
Drilling
1. Use sharp drill bits only. For WOOD, use twist
drill bits, spade bits, power auger bits, or hole
saws. For METAL, use high-speed steel twist
drill bits or hole saws. For MASONRY, such as
brick, cement, cinder block etc., use carbide-
tipped bits.
2. Be sure the material to be drilled is anchored
or clamped firmly. If drilling thin material, use
a wood “back-up” block to prevent damage to
the material.
3. 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.
4. Hold drill firmly to control the twisting action of
the drill. Use side handle.
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.
5. 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 off and on in an attempt to start a
stalled drill- this can dammge the drill.
6. To minimize stalling on breaking through the
material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
7. Keep the motor running when pulling the bit
back out of a drilled hole. This will help prevent
amming.
Drilling in Wood
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.
For larger holes, use spade bits, power auger bits,
or hole saws. Work that is likely to splinter should be
backed up with a block of wood.
Drilling in Metals
Use a cutting lubricant when drilling metals. The
exceptions are cast iron and brass which should be
drilled dry. The cutting lubricants that work best are
sulphurised cutting oil or lard oil; bacon grease will
also serve the purpose.
Drilling in Masonry
Use carbide tipped masonry bits at low speeds.
Keep even force on the drill but not so much that
you crack the brittle materials. A smooth, even flow
of dust indicates the proper drilling rate
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.
