Cleaning
The machine must be switched off and unplugged before cleaning and maintenance.
Filter replacement
The fine filter must be replaced at least once a year. Only OEM filters may be used.
HEPA filters must be replaced after 300 hours.
Filter replacement may only be performed by trained personnel. Use a protective
mask and suitable equipment.
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.
