Caution: This tool must be grounded while in use to protect the operator from electric shock.

In the event of a malf unc tion or breakdown, groundi ng pr ovides a path of least resistance for electric
current to r educ e the risk of electric shock. This tool is equipped with an elect r ic cord having an
equipment -grounding conductor and a gr ounding plug. The plug must be plugged into a matc hing outlet
that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modi fy the pl ug pr ovided. If it will not fit the outlet, have the proper outlet installed by a qualified
electrician.

Improper connection of the equipment-grounding conduct or c an r esul t in a risk of electric shock. The
conductor, with insulation having an out er surface that is green with or without yellow stripes, is the
equipment -grounding conductor. If repair or replacement of t he electric c or d or plug is necessary, do not
connect the equi pment-groundi ng c onduc tor to a li ve terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not c ompletel y
understood, or if in doubt as to whether t he tool is properl y gr ounded. Use only three wire extension
cords that have three-prong grounding plugs and three-pole r ec eptacles that accept the tool’s plug.

Repair or replace a damaged or worn cord immedi ately.

this plug to a two-pole receptacl e, as shown in (B) if a proper ly grounded outlet is not av ailable. The
temporary adapter should only be used until a properly gr ounded outlet can be inst alled by a qualified
electrician. T his adapter is not applicable in Canada. The green colored rigid ear, lug, or tab,
extendi ng from the adapter, must be c onnec ted to a permanent gr ound such as a properly grounded
outlet box, as shown in (B).
