Improper connection of the equipment-grounding conductor can result in 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 in doubt as to whether the tool is properly grounded.
