The vacuum has been built in compliance with machine Directive 89/392/EEC and the CE symbol is affixed to the
machine itself.
WARNING!
This symbol is used to call your attention to dangerous operations or machine parts that could cause
personal injuries or even the death of the operator. Irreparable damage to the machine is also possible
where this symbol is used.
Note
