and downwards, the exhaust fume deposits are completely removed from the filter and the filter is refreshed. The separated
dust is collected in the dust collecting drawer.

NOTICE
• The dust collecting drawer (8) must be emptied before and after each dedusting of the filter.
• If the dedusting of the filter has no effect on the suction power, the filter must be replaced.
5.3 Replace the filter cartridge
After longer operating times, the fine dust penetrates into the filter and the filter becomes clogged. Even a dedusting of the
filter cannot remove this dust. The filter must be replaced by a new one.
