DANGER
Risk of injury. Class L and Class M vacuum cleaners contain dust that is hazardous to the health.
▶ Emptying and maintenance, including disposal of the dust collection container, may be carried out
only by trained and qualified specialists. Wear the appropriate protective equipment.
▶ Before removing the vacuum cleaner from an area contaminated with hazardous substances,
use the vacuum cleaner to clean off its own exterior, wipe it clean or place it in a sealed bag
or container. As all parts of the appliance must be considered to be contaminated, suitable
measures to avoid spreading the dust must be implemented before these parts are removed from
the hazardous area.
▶ Never operate the vacuum cleaner without the complete filter system fitted.
