Grounding
⚠
WARNING
This machine must be grounded while in use to protect the operator from electrical shock. The
plug MUST be plugged into a matching receptacle that is properly installed and grounded in
accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper
receptacle installed by a qualified electrician.
CHECK with a qualified electrician or service person if you do not completely understand the
grounding instructions, or if you are not sure the tool is properly grounded.
Grounded Tools: Tools with 3-Prong Plugs
Tools marked with
Grounding Required
have a 3-wire cord and 3-prong grounding plug. The plug
must be connected to a properly grounded outlet. If the air mover 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. (See FIGURE A.)
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 air mover 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 the following
illustration.
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.
(See FIGURE B.)
Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration.
