WARNING To reduce the risk of injury,
always wear eye protection.
Chuck Removal
This tool is equipped with a threaded spindle to hold
the chuck. Before removing the chuck, unplug the
tool and open the chuck jaws. A left-handed thread
screw is located inside the chuck to prevent the
chuck from loosening when the tool is operated in
reverse direction. Remove the screw by turning it
clockwise. To remove the chuck, hold the tool so that
only the side of the chuck rests fi rmly and squarely
on a solid workbench. Insert the chuck key or a chuck
remover bar in one of the keyholes. Turn the chuck
so the key is at about a 30° angle to the bench top
Fig. 10
and strike the key
sharply with a ham-
mer so the chuck
turns in a counter-
clockwise direction
(looking from the
front of the tool). This
should loosen the
chuck from the spin-
dle which has a right
hand thread making
it easy to remove the
chuck by hand.
NOTE: When replacing the chuck, always replace
the left hand thread screw in the chuck.
OPERATION
WARNING To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
Using Forward/Reverse Switch
Forward

Reverse
Switch Fig. 11
1. For forward (clockwise) rotation, push the for-
ward/reverse switch to the left position as shown.
WARNING To reduce the risk of injury,
keep hands and cord away from the bit and
all moving parts.
Starting, Stopping and Controlling Speed
1. To start the tool, pull the trigger.
2. To stop the tool, release the trigger.
3. To vary the drilling speed, simply increase or
decrease pressure on the trigger. The further
the trigger is pulled, the greater the speed.
Locking Trigger
The lock button holds the trigger in the ON position
for continuous full speed use.
1. To lock the trigger, hold the lock button in while
pulling the trigger. Release the trigger.
2. To unlock the trigger, pull the trigger and release.
The lock button will pop out.
2. For reverse (counterclockwise) rotation, push
the forward/reverse switch to the right position
as shown. Although an interlock prevents revers-
ing the tool while the motor is running, allow it to
come to a full stop before reversing.

WARNING To reduce the risk of explo-
sion, electric shock and property damage,
always check the work area for hidden pipes
and wires before drilling.
Selecting Bits
When selecting a bit, use the right type for your
job. For best performance, always use sharp bits.
Drilling
1. Before drilling, be sure the workpiece is clamped
securely. Use backing material to prevent dam-
age 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. Always apply pressure in line with the bit. Use
enough pressure to keep the drill biting, but do
not push hard enough to stall the motor.
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.
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 melting 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 material
to prevent binding and distortion on breakthrough.
Driving Screws
When driving screws, use the proper screwdriver
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.
Stalling
If the tool seems as if it is about to stall, maintain a
fi rm grip and reduce pressure slightly to allow the
bit to regain speed. If the tool does stall, release
the trigger immediately. Reverse the motor, remove
the bit from the work and start again. Do not pull
the trigger on and off in an attempt to start a stalled
drill. This can damage the drill.
WARNING High rotational force. To
reduce the risk of injury, always hold or brace
securely. Always use side handle on tools
rated 1200 rpm or less.
Bit Binding
A high rotational force occurs when a bit binds. If
the bit binds, the tool will be forced in the opposite
direction of the bit rotation (See Fig. 12-14). Bits
may bind if they are misaligned or when they are
breaking through a hole. Wood boring bits can also

bind if they run into nails or knots. Be prepared for
bit binding situations.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely to bind
when drilling.
• Use the proper bit for the job. There are bits that
are designed for specifi c purposes.
• Use caution when drilling pitchy, knotty, wet or
warped material or when drilling in material that
may contain nails.
