SPECIFIC SAFETY RULES

•  Hold power tool 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 

also make exposed metal parts of the tool “live” 
and shock the operator.

•  Use clamps or another practical way to se-

cure and support the workpiece to a stable 
platform. 

Holding the work by hand or against 

your body leaves it unstable and may lead to loss 
of control.

•  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, depend-

ing 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.

PERSONAL SAFETY

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 atmo-

spheres, 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 elec-

tric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet con-

ditions. 

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.

• 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.

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.

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 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.

BATTERY TOOL USE AND CARE

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.

• 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 eject-

ed 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 irrita-
tion or burns.
