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 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 equip-
ment.
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 haz-
ardous dust to escape. Never use old gaskets or non-OEM parts. Place used filters in a plastic bag and seal the bag. See instruc-
tions 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 sec-
ond 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.
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.
