To lock the trigger, push the control switch to the
center position. The trigger will not work while
the control switch is in the center locked position.
Always lock the trigger or remove the battery
pack before performing maintenance, changing
accessories, storing the tool and any time 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 bit comes to a complete stop before laying
the tool down.
Drilling
Place the bit on the work surface and apply fi rm
pressure before starting. Too much pressure will
slow the bit and reduce drilling effi ciency. Too little
pressure will cause the bit to slide over the work
area and dull the point of the bit.
If the tool begins to stall, reduce pressure slightly to
allow the bit to regain speed. If the bit binds, reverse
the motor to free the bit from the workpiece.
ACCESSORIES
WARNING
Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
For a complete listing of accessories refer to your
MILWAUKEE Electric Tool catalog or go online to
www.milwaukeetool.com. To obtain a catalog, con-
tact your local distributor or a service center listed
on the back cover of this operator's manual.

APPLICATIONS
WARNING
To reduce the risk of elec-
tric shock, check work area for hidden pipes
and wires before drilling or driving screws.
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.
Drilling in Metal
When drilling in metal, use high speed steel twist
drills or hole saws. Use a center punch to start the
hole. Lubricate drill bits with cutting oil when drilling
in iron or steel. Use a coolant when drilling in non-
ferrous metals such as copper, brass or aluminum.
Back the material to prevent binding and distortion
on breakthrough.
Drilling in Masonry
When drilling in masonry, select the
drill operating mode. 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.
Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or
hard materials. Set the torque selector collar to the
proper position and set the speed to low. Use the
proper style and size screwdriver bit for the type
of screw you are using.
With the screwdriver bit in the screw, place the tip of
the screw on the workpiece and apply fi rm pressure
before pulling the trigger. Screws can be removed
by reversing the motor.
Overloading
Continuous overloading may cause permanent
damage to tool or battery pack.

WARNING
High rotational force. To
reduce the risk of injury, always hold or brace
securely. Always use side handle on tools.
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 situ-
ations. 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.

ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program
After six months to one year, depending on use
return the tool, battery pack and charger to A
MILWAUKEE service facility for:
• Lubrication
• Mechanical inspection and cleaning (gears
spindles, bearings, housing, etc.)
• Electrical inspection (battery pack, charger
motor)
rotation
• Testing to assure proper mechanical and
electrical operation
If the tool does not start or operate at full powe
with a fully charged battery pack, clean the contacts
on the battery pack. If the tool still does not work
properly, return the tool, charger and battery pack
to a MILWAUKEE service facility for repairs.
Reaction
WARNING
sonal injury and damage, never immerse your
tool, battery pack or charger in liquid or allow
a liquid to fl ow inside them.

vents. Keep tool handles clean, dry and free of o
or grease. Use only mild soap and a damp cloth
to clean the tool, battery pack and charger since
Reaction
certain cleaning agents and solvents are harmful to
plastics and other insulated parts. Some of these
include gasoline, turpentine, lacquer thinner, pain
thinner, chlorinated cleaning solvents, ammonia
and household detergents containing ammonia
Never use flammable or combustible solvents
around tools.
