WARNING
TOOL ASSEMBLY
To reduce the risk of injury,
always unplug tool before attaching
or removing accessories or making
adjustments. Use only specifi cally
recommended accessories. Others
may be hazardous.
Installing Bits into Keyed Chucks
1. Open the chuck jaws wide enough to
insert the bit. Be sure the bit shank and
chuck jaws are clean. Dirt particles may
prevent the bit from lining up properly.
2. When using drill bits, insert the bit into
the chuck. Center the bit in the chuck
jaws and lift it about 1/16" off of the bot-
tom. Tighten the chuck jaws by hand to
align the bit.
When using screwdriver bits, insert the
bit far enough for the chuck jaws to grip
the bit shank. Tighten the chuck jaws by
hand to align the bit.
3. Place the chuck key in each of the three
holes in the chuck, turning it clockwise
as shown. Tighten securely.
4. To remove the bit, insert the chuck key
into one of the holes in the chuck and
turn it counterclockwise.
Using Forward/Reverse Switch
1. For forward (clockwise) rotation, slide
the forward/reverse switch to the left.
2. For reverse (counterclockwise) rotation,
slide the forward/reverse switch to the
right.
NOTE: To prevent damage to the motor,
allow the tool to come to a complete stop
before reversing.

WARNING
To prevent personal injury, always
remove the chuck key from the
chuck after each use.
WARNING
To reduce the risk of injury, wear
safety goggles or glasses with side
shields. Unplug the tool before
changing accessories or making
adjustments.
OPERATION
WARNING
To reduce the risk of explosion,
electric shock and property dam-
age, always check the work area
for hidden electrical wires or pipes
when drilling.

Starting, Stopping and Controlling
Speed
1. To start the tool, pull the paddle
switch.
2. To stop the tool, release the paddle
switch.
3. To vary the driving speed, increase or
decrease pressure on the paddle switch.
The further the paddle switch is pulled,
the greater the speed.
APPLICATIONS
Selecting Bits
When selecting a bit, use the right type for
your job. For best performance, always use
sharp bits.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, start the drill slowly, gradually
increasing speed as you drill. When using
twist drill bits, pull the bit out of the hole
frequently to clear chips from the bit fl utes.
Use low speeds for plastics with a low melt-
ing point.
Drilling in Masonry
When drilling in masonry, use high speed
carbide-tipped bits. Drilling soft masonry
materials such as cinder block requires
little pressure. Hard materials like concrete
require more pressure. A smooth, even fl ow
of dust indicates the proper drilling rate. Do
not let the bit spin in the hole without cutting.
Do not use water to settle dust or to cool bit.
Both actions will damage the carbide.
Drilling in Metal
When drilling in metal, use high speed steel
twist drills or hole saws. Use slow speeds
for hard metals and high speeds for softer
metals. Lubricate drill bits with cutting oil
when drilling in iron or steel. Use a coolant
when drilling in nonferrous metals such as
copper, brass or aluminum. Back the ma-
terial to prevent binding and distortion on
breakthrough.
Driving Screws
When driving screws, use the proper screw-
driver bit for your job. After drilling pilot and
shank holes, start the screw slowly and
increase the speed as driving progresses.
Set the screw by slowing to a stop. Do not
run screws down at excessive speeds. To
remove screws, reverse the motor.
WARNING
To reduce the risk of explosion,
electric shock and property dam-
age, always check the work area
for hidden electrical wires or pipes
when drilling.
Drilling
1. Before drilling, be sure the workpiece is
clamped securely. Use backing material
to prevent damage to the workpiece
during breakthrough.
2. When starting a hole, place the drill
bit on the work surface and apply fi rm
pressure. Begin drilling at a slow speed,
gradually increasing the speed as you
drill.
3. Use enough pressure on the tool to keep
the bit drilling or driving constantly, but
do not push hard enough to stall the
bit.
4. Reduce pressure and ease the bit
through the last part of the hole. While
the tool is still running, pull the bit out of
the hole to prevent jamming.
Stalling
If the tool seems as if it is about to stall, main-
tain a fi rm grip and reduce pressure slightly to
allow the bit to regain speed. If the tool does
stall, release the paddle switch immediately.
Reverse the motor, remove the bit from the
work and start again. Do not press the paddle
switch on and off in an attempt to start a
stalled drill. This can damage the drill.
