SAFETY INSTRUCTIONS
Servicing of double-insulated machines
In a double-insulated machine, two sys­tems of insulation are provided instead of grounding. No grounding means is provid­ed 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 knowl­edge of the system, and should be done only by qualified service personnel. Re­placement parts for a double-insulated ma­chine must be identical to the parts they replace.
6 EN
Please read and comply with
these original instructions prior to the initial operation of your appliance and store them for later use or subsequent own­ers.
The non-compliance of the operating
and safety instructions may lead to damages of the appliance and to dan­gers for the operator and other persons.
In case of transport damage inform ven-
dor immediately
