OPERATION
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.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
Using Forward/Reverse Switch
1. For forward (clock-
wise) rotation, push
Forward
the forward/reverse
◄
switch to
as shown.
2. For reverse (counter-
clockwise) rotation,
push the forward/re-
►
verse switch to
.
Although an interlock
Reverse
prevents reversing the
tool while the motor is
running, allow it to come to a full stop before
reversing.
WARNING
To reduce the risk of injury,
keep hands and cord away from the bit and
all moving parts.
WARNING
High rotational force. To
reduce the risk of injury, always hold or brace
securely.
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, increase or decrease
pressure on the trigger. The further the trigger is
pulled, the greater the speed.
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.
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.
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.
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 Material & 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.

WARNING
High rotational force. To
reduce the risk of injury, always hold or brace
securely.
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. 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.
ACCESSORIES
WARNING
To reduce the risk of injury,
always unplug the tool before attaching or
removing accessories. Use only specifi cally
recommended accessories. Others may be
hazardous.
For a complete listing of accessories refer to your
MILWAUKEE Electric Tool catalog or go on-line
to www.milwaukeetool.com. To obtain a catalog,
contact your local distributor or a service center.
MAINTENANCE
WARNING
To reduce the risk of
injury, always unplug your tool before
performing any maintenance. Never disas-
semble the tool or try to do any rewiring
on the tool's electrical system. Contact a
MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general condition of your tool. Inspect guards,
switches, tool cord set and extension cord for
damage. Check for loose screws, misalignment,
binding of moving parts, improper mounting, bro-
ken parts and any other condition that may affect
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. Tag damaged tools "DO NOT USE"
until repaired (see "Repairs").
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electri-
cal operation
To reduce the risk of injury,
WARNING
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to fl ow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
