RULES FOR SAFE OPERATION
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug
must be connected to a properly grounded outlet. See Figure A. If the tool should electrically malfunction
or break down, grounding provides a low resistance path to carry electricity away from the user, reducing
the risk of electric shock.
The grounding prong in the plug is connected through the green wire inside the cord to the grounding
system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding
system and must never be attached to an electrically “live” terminal.
Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with
all codes and ordinances. The plug and outlet should look like those in Figure A.
Figure B illustrates a temporary adapter available for connecting grounded plugs (Figure A) to two prong
outlets. The green rigid ear or lug extending from the adapter must be connected to a permanent ground
such as a properly grounded outlet box or receptacle. Simply remove the center screw from the outlet,
insert the adapter and reattach the screw through the green grounding ear to the outlet. If in doubt of
proper grounding, call a qualified electrician. A temporary adapter should only be used until a properly
grounded outlet can be installed by a qualified electrician. The Canadian Electrical Code prohibits the use
of temporary adapters.

WARNING:
Electrical cords can be hazardous. Misuse can result in fire or death by electrical
shock. Read carefully and follow all directions.
WARNING:
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do
not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not
use the tool if the cord or plug is damaged. If the plug will not fit the outlet, have a proper outlet
installed by a qualified electrician.
