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.

	Waste hose (Order no. 9.990-261.0)
	Main filter (Order no. 9.990-222.0)

   Note

   With light suction material, the length of the waste bag can be up to 2 m without the waste bag tearing.

A pressure gauge showing the vacuum inside the device is mounted on the front of the device. The main filter must be cleaned when the maximum vacuum (see table) is reached (see chapter Dedusting the main filter). This value depends on the device performance and the suction hose used. If the vacuum is not significantly reduced by dedusting, the filter must be replaced (see chapter Replacing the main filter).

The main filter must be cleaned if the pressure gauge shows the maximum vacuum (see chapter Reading the minimum volumetric flow).
