keep hands away from the bit and all moving
parts. Always wear safety goggles or glasses

Installing Bits into Keyed Chuck
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
bottom. 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 counterclock-
wise.
Forward/Reverse/Trigger Lock Switch
To set the direction of bit rotation or lock
the trigger, move the forward/reverse/trig-
ger lock switch to the following positions:
For
forward
rotation (clockwise): Move the
switch to the right." " will be displayed
above the switch. To vary the speed in
forward rotation, increase or decrease
pressure on the trigger.
For
reverse
rotation (counter-clockwise):
Move the switch to the left. " " will be dis-
played above the switch. To vary the speed
in reverse rotation, increase or decrease
pressure on the trigger.
To
lock
the trigger: Move the switch to the
center. " " will be displayed above the
switch. The trigger will not work while the
switch is in the locked position. Always lock
the trigger and remove the battery pack be-
fore performing maintenance and changing
accessories. Lock the trigger when storing
the tool and when the tool is not in use.
Starting, Stopping and Controlling Speed
1. To
start
the tool, grasp the handle fi rmly and pull
the trigger.
2. To
vary
the speed, increase or decrease the
pressure on the trigger. The further the trigger
is pulled, the greater the speed.
3. To
stop
the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Electric Brake
The electric brake engages when the trigger is
released, causing the bit to stop and allowing you
to proceed with your work. Generally, the bit stops
within two seconds. However, there may be a delay
between the time you release the trigger and when
the brake engages. Occasionally the brake may
miss completely. If the brake misses frequently, the
tool needs servicing by an authorized
MILWAUKEE
service facility.

WARNING
To reduce the risk of
personal injury, always brace or hold the tool
securely. Brace tools with side handles as
shown. If the bit binds, the tool will be forced
in the opposite direction. Bits may bind if they
are misaligned or when breaking through a
hole. Wood boring bits can also bind if they
run into nails or knots.

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 drilling into wood, use
wood augers or twist drill bits. Always use sharp
bits. When using twist drill bits, pull the bit out of the
hole frequently to clear chips from the bit fl utes. To
reduce the chance of splintering, back work with a
piece of scrap wood. Select low speeds for plastics
with a low melting point.
