The three motors (3300 W): One switch turns on two suction motors, and the other switch turns on the third
motor.
If the task requires a particularly gentle dust collection, the number of active suction motors can be adjusted
accordingly.
Vacuum Indicator and Filter Cleaning during Operation
The vacuum indicator placed on the adapter ring measures the vacuum between the filters of the machine
during operation.
If the multi-tube filter is blocked by fine particles, the air pressure in
the machine will fall. This will be indicated by the vacuum indicator.
The pointer of the vacuum indicator reaching the read area indicates
that the air velocity in the hose and in the tube is too low, and that the
multi-tube filter therefore needs to be cleaned.
The multi-tube filter can be cleaned during operation, i.e. while the
machine is working.
 Remove the hose from the tube.
 Block the suction of the hose so that full vacuum is made.
Vacuum will now be formed inside the machine and in the hose.
At the same time the springs of the multi-tube filter will contract a
little.
