IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The
conductor with the green insulation (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 licensed electrician or service personnel if you do not completely understand the
grounding instructions, or if you are not sure if the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have 3-pronged plugs and outlets that accept
the tool's plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure
if it is, have a licensed electrician check the outlet.
