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.
WARNING
Risk of injury. Damage to the filter system may allow harmful dust (health hazard) to escape.
▶ In an emergency (e.g. filter ruptured), switch the vacuum cleaner off, unplug the supply cord from the
power outlet and have the vacuum cleaner checked by a trained and qualified person before further use.
CAUTION
Risk of injury presented by the appliance running away out of control. The vacuum cleaner may run
away out of control if the wheel brakes are not engaged.
▶ Engage the wheel brakes so that the vacuum cleaner stands securely.
