6. Set the minimum volume flow on the turn switch for

suction hose cross section. The scale shows the

suction hose suction hose cross section.

Note

The different suction hose cross sections are necessary

in order to adapt to the different connection cross sec-

tions of the processing machines.

Note

For operation as a dust removal device for mobile oper-

ation (processing machine plugged into the vacuum

cleaner) the integrated monitoring system must be ad-

justed to suit the connected processing machine (dust

generator). This means that the user must be warned

when the flow rate drops below the minimum value 20

m/s needed for correct vacuuming.

Note

Information on the minimum flow rate depending on the

vacuum can be found on the type plate.

Automatic filter dedusting

The device is equipped with a special filter dedusting

function, which is particularly effective against fine dust.

The flat fold filter is automatically cleaned every 7.5/15/

60 seconds (depending on use) using an airflow (puls-

ing sound).

1. Set the turn switch to program 2 (TACT AUTO).

2. Power dedusting (for particularly severe contamina-

tion of the flat fold filter): Set the turn switch to pro-

gram 2, seal the suction pipe or bender with your

hand and wait for the automatic filter cleaning to fin-

ish (lasts 15 seconds).
