GROUNDING INSTRUCTIONS
1. All grounded, cord-connected tools: 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.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a
qualified electrician. 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 cold or plug is
necessary, do not connect the equipment-grounding conductor to a live terminal.
Check-with a qualified electrician or service personnel if the grounding instructions are not
completely understood or if in doubt as to whether there tool is properly grounded. Use only 3-wire
extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.
Repair or replace damage or worn cord immediately.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating
less than 150 volts. This tool is intended for use on a circuit that has an outlet that looks like the one
illustrated in Sketch A in Figure the tool has a grounding plug that looks like the plug illustrated in
Sketch A in Figure A temporary adapter, which looks like the adapter illustrated in Sketches B and C,
may be used to connect this plug to a 2-pole receptacle as shown in Sketch B if a properly grounded
outlet is not available. The temporary adapter should be use only until a properly grounded outlet can
be installed by a qualified electrician. The green-colored rigid ear, plug, and the like extending from the
adapter must be connected to a permanent ground such as a properly grounded outlet box.
3. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating
between 150-250 volts, inclusive: This tool is intended for use on a circuit that has an outlet that looks
like the one illustrated in Sketch D in Figure. The tool has a grounding plug that looks like the plug
illustrated in Sketch D.
Make sure the tool is connected to an outlet having the same configuration as the plug. No
adapter is available or should be used with this tool. If the tool must be reconnected for use on a
different type of electric circuit, the reconnection should be made by qualified service personnel; and
after reconnection, the tool should comply with all local code and ordinances.
