3.5 Warning tone
UM and UME vacuum cleaners emit an audible warning tone. This warning tone is emitted when the air
speed in the hose drops below 20 m/s.
In order to ensure that the warning tone is emitted correctly, the hose diameter setting must be set to the
diameter of the suction hose in use.
3.6 Automatic filter cleaning
The vacuum cleaner is equipped with an automatic filter cleaning system that removes most of the dust
adhering to the filter element.
The filter cleaning system can be switched off by pressing the "Automatic filter cleaning ON/OFF" 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).
Note
In order to achieve continuously high suction performance in system applications (especially grinding
and sanding, cutting and slitting) or when picking up large quantities of dust, the filter cleaning system
must be active.
The filter cleaning system functions only when a suction hose is connected.
