Grounding Instructions
WARNING: Be sure the system is properly grounded before applying power. Do not apply power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. Follow the National Electrical Code (NEC) and local codes for the safe installation
of this equipment.
1. All grounded, cordconnected grinders:
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 grinder is
equipped with an electric cord having an equipmentgrounding 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 equipmentgrounding conductor can result in a risk of
electric shock. The “Green” insulated wire (with or without yellow stripes) is the
equipmentgrounding conductor. If repair or replacement of the electric cord is
necessary, do not connect the equipmentgrounding conductor to a live terminal. Check
with a qualified electrician or serviceman if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded.
Use only 3wire extension cords that have 3prong grounding plugs and 3pole
receptacles that accept the tool’s plug.
Repair or replace damaged or worn cord immediately.
