Hilti VC 20H-X Manuel D'utilisation page 31

The vacuum cleaner has manual and automatic filter cleaning that removes most of the dust adhering to the
filter element.
Automatic filter cleaning can be switched off by pressing the "Automatic filter cleaning" button and switched
back on by pressing the button again.
Status
LED lights.
LED doesn't light.
The filter cleaning system is activated automatically each time the vacuum cleaner is switched on.
The filter element is cleaned automatically by a blast of air (a pulsating noise is heard).
In order to maintain continuously high suction power, in system applications (especially grinding and
sanding, cutting and slitting) or when collecting large quantities of dust, automatic filter cleaning must
be activated.
Independently of automatic filter cleaning, you can clean the filter at any time by pressing the "Manual filter
cleaning" button.
Power cleaning: To achieve maximum power for filter cleaning, press the "Manual filter cleaning"
button while at the same time keeping the end of the hose closed.
