Start up
Suction of normal- rough dirt can be un-
–
dertaken without any problem with the
integrated cartridge filter.
Change the filter, if required, according
–
to instructions under the section "Main-
tenance and Care".
Wet vacuum cleaning
Remove the filter bag for wet suction.
The cartridge filter must remain in-
stalled in the machine.
Completely empty the container after
finishing use.
A rough filter should be installed (Order No.
5.731-025.0) if liquid is to be sucked in con-
tinuously.
Note
If the container is full, a float closes the suc-
tion opening, and the suction turbine works
at a higher speed. Switch off the appliance
immediately, and empty the container.
Turning on the Appliance
Insert the appliance plug into the mains
socket. Do not use extension cables.
Switch on the appliance using the On/
Off switch (Position 1).
Automatic monitoring of suction ca-
The machine is equipped with a suction
power monitor. The control lamp lights up if
the air speed in the suction hose falls below
20 m/s.
Switch off the vacuum unit, replace full
filter bag with an empty one.
Check suction hose and attachments
for blocks.
The cartridge filter must also be re-
placed if the machine is used for long
periods.
