GENERAL POWER TOOL SAFETY WARNINGS
WARNING READ ALL SAFETY WARNINGS AND ALL 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.
• 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
WORK AREA 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 electric
shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water 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.
• 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 when impact drilling.
Exposure to noise can cause hearing loss.
• Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
Hammer Drill/Drivers and Drill/Drivers-
•Hold power tool by insulated gripping surfaces, when performing an operation where
the cutting accessory may contact hidden
wiring. Cutting accessory contacting a “live” wire
may make exposed metal parts of the power tool
“live” and could give the operator an electric shock.
Drivers-
• Hold power tool by insulated gripping surfaces, when performing an operation where the
fastener may contact hidden wiring. Fasteners
contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the
operator an electric shock.
• 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 sanding,
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 par-
ticles.

the bit comes to a complete stop before laying
the tool down.
Battery Pack Protection
To protect the battery from damage and extend
its life, the tool’s intelligent circuit monitors current
draw, temperature, and voltage drops.
In extremely high torque, binding, stalling, and short
circuit situations that cause high current draw, the
tool will vibrate for about 5 seconds, the fuel gauge
will fl ash, and then the tool will turn OFF. To reset,
release the trigger.
Under extreme circumstances, the internal temperature of the battery could become too high.
If this happens, the fuel gauge will fl ash and the
battery pack will shut off. Let the battery pack cool
and then continue work.
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, select the
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, select the drill-only
operating mode. 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.
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. Select the
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
