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-operat-

ed (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. Dam-

aged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable for out-

door 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 residual 

current device (RCD) protected supply. Use of an RCD 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 protec-

tion 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.
