Filter replacement
The fine filter must be replaced at least once a year. Only original filters may be used. HEPA filters must be replaced after
300 hours.
WARNING
Filter replacement may only be performed by trained personnel. Use a protective mask and suitable
equipment.
CAUTION
When replacing the filter, no tools/sharp objects can be used as these may damage the sealing surface of the
filter.
Release and lift off the upper part for free access to the filter. Lift the filter straight up. If appropriate, fit a plastic bag over the
cyclone to prevent the dust in the filter from spreading. Check the gasket when replacing the filter. A worn gasket can allow
hazardous dust to escape. Never use old gaskets or non-OEM parts. Place used filters in a plastic bag and seal the bag. See
instructions below.

Motor
The typical service life of a fan motor's original brushes is 600-700 hours. The brush can be replaced. The service life of the
second brush set is approx. 400 hours, while that of the third set is approx. 300 hours. After this time, the motor is considered
worn out and should be replaced.
Overheating
If the machine is at risk of overheating (for example, as a result of powerful throttling), the temperature guard will trip and the
machine will stop. The operator must then press the power switch to the OFF position, unplug from the mains and wait 3-5
minutes for the machine to cool down. Then reset the temperature guard by pressing the RESET button. Reconnect the power
cord to the electrical outlet and restart the machine by pressing the power switch to the ON position.
