Servicing of double-insulated machines
In a double-insulated machine, two sys-
tems of insulation are provided instead of
grounding. No grounding means is provid-
ed on a double-insulated machine, nor
should a means for grounding be added to
the machine. Servicing a double-insulated
machine requires extreme care and knowl-
edge of the system, and should be done
only by qualified service personnel. Re-
placement parts for a double-insulated ma-
chine must be identical to the parts they
replace.
