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).
