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 malfunc-
tion or break down, grounding provides allow 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 accor-
dance 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 prop-
erly 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.
Double Insulated Tools: Tools with Two Prong Plugs
Tools marked "Double Insulated" do not require grounding. They
have a special double insulation system which satisfies OSHA
requirements and complies with the applicable standards of
Underwriters' Laboratories, Inc., the Canadian Standard Association and the National Electrical
Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures C
and D or 240 volt as shown in Figure E.
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 damaged, return it immediately to your
local rental center to have it repaired by a MILWAUKEE service facility
before use. If the plug will not fit the outlet, have a proper outlet installed
by a qualified electrician.
