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.

Turbo pump
The turbo pump has a very long service life without any special maintenance. After approx. 10,000 operating hours, the radial
seal between the motor and turbo pump must be lubricated with grease. Bearings and seals, in both motor and pump, must be
checked and lubricated. Worn parts must be replaced.
Regular checks
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 must be replaced. Never risk functionality and service life. Only use genuine parts.
