GENERAL POWER TOOL SAFETY WARNINGS

WORK AREA SAFETY

ELECTRICAL SAFETY

• Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

• Do not operate power tools in explosive atmos-

pheres, 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.

• 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 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

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.

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.

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.

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 pre-
ventive safety measures reduce the risk of starting
the power tool accidentally.

• Store idle power tools out of the reach of chil-

dren 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.

• 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 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 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

SPECIFIC SAFETY RULES

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.

• Hold power tool by insulated gripping surfaces,

because the belt may contact its own cord.
Cutting a “live” wire may make exposed metal
parts of the 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.
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 spe-
cially designed to fi lter out microscopic particles.

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
greater the capacity of the cord. For example, a 14
gauge cord can carry a higher current than a 16
gauge 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 size.

Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be

sure it is marked with the suffi x “W-A” (“W” in Cana-
da) to indicate that 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
qualifi ed person before using it.

• Protect your extension cords from sharp objects,

excessive heat and damp or wet areas.
