The maximum vacuum value in relation to the hose cross-section is specified on the label. The actual value can be read on the pressure gauge. For the values applicable to this device, see chapter Reading the minimum volumetric flow. If this value is not reached, the filter must be cleaned (see chapter Dedusting the main filter) or replaced (see chapter Replacing the main filter). The various different hose cross-sections allow adaptation to the various different connection cross-sections of the accessories.

	Dust bag (Order no. 9.989-606.0)
	Safety filter bag (Order no. 6.904-420.0)
	Main filter (Order no. 9.990-222.0)
