MAINTENANCE GENERAL DOUBLE INSULATION All parts represent an important part of the double insulation system and should be serviced only at a Sears Service Center. Double insulation is a concept in safety in electric power toots, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. Avoid using solvents when cleaning plastic parts.
