3.7 Acoustic warning
VC 20M-X
VC 40M-X
M-class vacuum cleaners have an acoustic warning signal. The acoustic warning is emitted for safety
reasons when the air speed in the hose drops below 20 m/s.
In order to ensure that the acoustic warning is emitted correctly, the hose diameter setting must be set to
the diameter of the suction hose in use.
3.8 Filter cleaning
The filter cleaning system functions only when a suction hose is connected.
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 Meaning
LED lights. The filter cleaning system is active.
LED doesn’t light. The filter cleaning system is not active.
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.
