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.
