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, 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.

1) Work Area Safety

a ) 

Keep work area clean and well lit.

 Cluttered or dark 

areas invite accidents.

b ) 

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.

c ) 

Keep children and bystanders away while 
operating a power tool.

 Distractions can cause you 

to lose control.

2) Electrical Safety

a ) 

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.

b ) 

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.

c ) 

Do not expose power tools to rain or wet 
conditions. 

Water entering a power tool will increase 

the risk of electric shock.

d ) 

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.

e ) 

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.

f ) 

If operating a power tool in a damp location 
is unavoidable, use a ground fault circuit 
interrupter (GFCI) protected supply. 

Use of a GFCI 

reduces the risk of electric shock.

3) Personal Safety

a ) 

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.

b ) 

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.

c ) 

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 energizing power tools that 
have the switch on invites accidents.

d ) 

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.

e ) 

Do not overreach. Keep proper footing and 
balance at all times. 

This enables better control of 

the power tool in unexpected situations.

f ) 

Dress properly. Do not wear loose clothing or 
jewelry. Keep your hair, clothing and gloves 
away from moving parts. 

Loose clothes, jewelry or 

long hair can be caught in moving parts.

g ) 

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.

4) Power Tool Use and Care

a ) 

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.

b ) 

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.

c ) 

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.

d ) 

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.

e ) 

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.

f ) 

Keep cutting tools sharp and clean. 

Properly 

maintained cutting tools with sharp cutting edges are 
less likely to bind and are easier to control.

g ) 

Use the power tool, accessories and tool bits, etc. 
in accordance with these instructions, taking 
into account the working conditions and the
