DANGER
Risk of injury. Class L, class M and class H vacuum cleaners contain dust that is hazardous to 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.

bit system.

instructions and information printed at the power outlet on the appliance).
3. Check to ensure that the electric tool is switched off before plugging its supply cord into the power outlet.
