To reduce the risk of injury, user must read and understand operator's
follow the warnings and instructions may result in electric shock, fire 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.
•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, jewellery 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.
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 flammable
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. Unmodified 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.
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.
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 influence of drugs, alcohol or medication. 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 finger on the switch or energising power tools
that have the switch on invites accidents.
•Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

MIWLAUKEE® 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 filter out microscopic
• Wear ear protection. Exposure to noise can cause
hearing loss.
• It is recommended that this tool is always supplied with
power via a residual current device with a rated residual
current of 30 mA or less.
• Use auxiliary handle(s), if supplied with the tool.
Loss of control can cause personal injury.
• Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
Waccessory may contact hidden wiring or its own
cord. Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool “live” and
could give the operator an electric shock.

Grounded tools require a three wire extension cord.
Double insulated tools can use either a two or three
wire extension cord. As the distance from the supply
outlet increases, you must use a heavier gauge
extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the less
the capacity of the cord. When using more than one
extension cord to make up the total length, be sure
each cord contains at least the minimum wire size
required. If you are using one extension cord for
more than one tool, add the nameplate amperes and
use the sum to determine the required minimum wire
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure
it is acceptable for outdoor use.
• Be sure your extension cord is properly wired and in
good electrical condition. Always replace a
damaged extension cord or have it repaired by a
qualified person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
