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 bystanders, children, and visitors away while operating a power tool.  

Distractions can cause you to lose control.  Protect others in the work area from 
debris such as chips and sparks.  Provide barriers or shields as needed.

ELECTRICAL SAFETY

4. 

Grounded tools must be plugged into an outlet properly installed and grounded 
in accordance with all codes and ordinances.  Never remove the grounding 
prong or modify the plug in any way.  Do not use any adapter plugs.  Check with 
a qualified electrician if you are in doubt as to whether the outlet is properly 
grounded.

  If the tools should electrically malfunction or break down, grounding 

provides a low resistance path to carry electricity away from the user.

5. 

Double insulated tools are equipped with a polarized plug (one blade is wider 
than the other).  This plug will fit in a polarized outlet only one way.  If the plug 
does not fit fully in the outlet, reverse the plug.  If it still does not fit, contact 
a qualified electrician to install a polarized outlet.  Do not change the plug in 
any way.

  Double insulation 

 eliminates the need for the three wire grounded 

power cord and grounded power supply system.

6. 

Avoid body contact with grounded surfaces such as pipes, radiators, ranges, 
and  refrigerators.   

There  is  an  increased  risk  of  electric  shock  if  your  body  is 

grounded.

7. 

Do not expose power tools to rain or wet conditions.  

Water entering a 

power tool will increase the risk of electric shock.

8. 

Do not abuse the Power Cord.

  

Never use the Power Cord to carry the tools 

or pull the Plug from an outlet.  Keep the Power Cord away from heat, oil, 
sharp edges, or moving parts.  Replace damaged Power Cords immediately.

  

Damaged Power Cords increase the risk of electric shock.

9. 

When operating a power tool outside, use an outdoor extension cord marked 
“W-A” or “W”.  

These extension cords are rated for outdoor use, and reduce the 

risk of electric shock.

PERSONAL SAFETY

 

10. 

Stay alert.  Watch what you are doing, and use common sense when operating 
a power tool.  Do not use a power tool while tired or under the influence of 
drugs, alcohol, or medication.

  A  moment of inattention while operating power 

tools may result in serious personal injury.
