Intake opening 11 air is sucked into the front housing part 8 and then flows through the prefilter 39, the pleated filter 30, the air passage openings and through the fan 2 and is then blown out of the blow-out opening 5. The arrows in Fig.2 illustrate the flow path of this air.

The dust contained in the sucked in air is first collected by the pre-filter 39, from which the larger dust particles or flakes are held in place in the front housing part 8 accumulate; the subsequent folded filter 30 holds back the finer dust particles that the pre-filter could happen.

If one wants to remove the dust caught in the dust collecting device 9, one proceeds as follows follows ahead.

The locking device 13 is unlocked, and the front housing part 8 is from the rear

Housing part 1 removed. The folded filter 30 is removed from a place suitable for emptying and the pre-filter 39 from the housing part 8, whereupon the larger dust cells or? -flakes through the

rear opening of this housing part :; S are poured out. Thereafter, the pre-filter 39 are opened and the animals located in the dust collecting chamber 41 fine dust particles removed, since the dust collection chamber 42 in the lower part of the dust hopper upstream 4D

is seen, which also contains the pleated filter 3 #, and since the partition wall 43 at the same time forms a frame structure for the prefilter 39 and thereby closes the dust funnel 40 towards the front, it is by no means necessary that each time the vacuum cleaner is emptied

In addition to the large flakes of dust collected in front of the pre-filter, it also removes the fine dust particles Need to become. Rather, you can always wait here until the dust collection chamber 42 is completely filled with fine dust.
