Grounding instructions
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 product 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 cord 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 you are in doubt as to whether the product is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles
that accept the product’s plug. Repair or replace damaged or worn cords immediately.
