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. 

Work area safety 

1. 

Keep work area clean and well lit.

 Cluttered or 

dark areas invite accidents. 

2. 

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. 

3. 

Keep children and bystanders away while 
operating a power tool.

 Distractions can cause 

you to lose control. 

Electrical safety 

4. 

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. 

5. 

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. 

6. 

Do not expose power tools to rain or wet 
conditions.

 Water entering a power tool will 

increase the risk of electric shock. 

7. 

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. 

8. 

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
