Service/Maintenance
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.

that of the third set is approx. 300 hours. After this time, the motor is considered worn
out and should be replaced.

Regularly check the power cord for damage. The machine must be tested and
inspected at least once a year due to its use with hazardous materials. Worn parts
