GROUNDING 

 

TO PREVENT ELECTRIC SHOCK AND 
DEATH FROM INCORRECT 
GROUNDING WIRE CONNECTION READ 

AND FOLLOW THESE INSTRUCTIONS:

110-120 VAC Grounded Tools: 

Tools with Three Prong Plugs

1.  In the event of a malfunction or breakdown, 

grounding provides a path of least resistance for 
electric current to reduce the risk of electric shock. 
This tool is equipped with an electric cord having an 
equipment-grounding conductor and a grounding 
plug.  The plug must be plugged into a matching 
outlet that is properly installed and grounded in 
accordance with all local codes and ordinances.

2.  Do not modify the plug provided – if it will 

not fit the outlet, have the proper outlet 
installed by a qualified electrician.

3.  Improper connection of the equipment-grounding 

conductor can result in a risk of electric shock. 
The conductor with insulation having an outer 
surface that is green with or without yellow 
stripes is the equipment-grounding conductor. 
If repair or replacement of the electric cord or 
plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.

4.  Check with a qualified electrician or service 

personnel if the grounding instructions are 
not completely understood, or if in doubt as 
to whether the tool is properly grounded.

5.  Use only 3-wire extension cords that 

have 3-prong grounding plugs and 3-pole 
receptacles that accept the tool’s plug.

6.  Repair or replace damaged or 

worn cord immediately.

protection.  Eye protection must be ANSI-approved 
and breathing protection must be NIOSH-approved 
for the specific hazards in the work area.

16.  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.
