SAFETY WARNINGS
WARNING
Read all safety warnings, instruc-
-
tions provided with this power tool. Failure to
follow all instructions listed below may result in
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 atmo-
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep children and bystanders away while operat-
ing 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.
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 condi-
tions. 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 ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use 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
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 a 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.
switch or energizing 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
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry 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.
Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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 and accessories. 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.
Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.

manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
RATCHETS
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 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.
Your 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
