GENERAL POWER TOOL SAFETY WARNINGS
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fi re and/or
serious injury.
Save all warnings and instructions for future reference
The term "power tool" in the warnings refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
• Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodifi ed plugs and matching outlets will
reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. W ater entering a power tool will increase
the risk of electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
• When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
• If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the infl uence of drugs, alcohol or medi-
cation. A moment of inattention while operating
power tools may result in serious personal injury.
• Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools
with your fi nger on the switch or energising power
tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair , clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
• Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
• Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
• Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
2
• Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits
etc., in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the power
tool for operations different from those intended
could result in a hazardous situation.
BA TTER Y T OOL USE AND CARE
• Recharge only with the charger specifi ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fi re
when used with another battery pack.
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or burns.
SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
SPECIFIC SAFETY RULES
• Wear ear protectors with impact drills. Expo-
sure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
• Hold power tools by insulated gripping sur-
faces when performing an operation where
the cutting tool may contact hidden wiring
or its own cord. Contact with a “live” wire will
make exposed metal parts of the tool “live” and
shock the operator.
• Keep hands away from all cutting edges and
moving parts.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
• WARNING: Some dust created by power sand-
ing, sawing, grinding, drilling, and other construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and
other masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Y our risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to fi lter out microscopic particles.

shields.
Using Keyless Chucks
Y our cordless tool is equipped with a spindle lock.
The chuck can be tightened with one hand, creating
higher grip strengths on the bit.
Always remove the battery pack or lock the trigger
before inserting or removing bits.
1. To open the chuck jaws, turn the sleeve in the
counterclockwise direction.
When using drill bits, allow the bit to strike the
bottom of the chuck. Center the bit in the chuck
jaws and lift it about 1/16" off of the bottom.
When using screwdriver bits, insert the bit far
enough for the chuck jaws to grip the hex of the
bit.
2. To close the chuck jaws, turn the sleeve in the
clockwise direction. The bit is secure when the
chuck makes a ratcheting sound and the sleeve
can not be rotated any further.
3. To remove the bit, turn the sleeve in the counterclockwise direction.
NOTE: A ratcheting sound may be heard when the
chuck is opened or closed. This noise is part of the
locking feature, and does not indicate a problem
with the chuck's operation.
Selecting Speed
The speed selector is on top of the motor housing.
Allow the tool to come to a complete stop before
changing speeds. See “Applications” for recommended speeds under various conditions.
1. For Low speed (up to 600 RPM), push the
speed selector to the left.
2. For High speed (up to 1800 RPM), push the

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
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.
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.
Drilling
Set both the hammer/drill and torque selector collars to the drill positions.
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.
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 nonferrous metals such as copper, brass or aluminum.
Back the material to prevent binding and distortion
on breakthrough.
6
Drilling in Masonry
When drilling in masonry, select the hammer-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
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.
