Automatic monitoring of suction
capacity
The machine is equipped with a suction
power monitor. The control lamp "Vacuum
pressure" lights up red if the air speed in the
suction hose falls below 20 m/s (see "As-
sistance in case of malfunctions").
Note: The control lamp "negative pressure"
can occasionally light up red during normal
operation (e.g., while working with a floor
nozzle), if the air volume comes down
(cross-sectional reduction) causing a lower
pressure.
Note: There is no defect in this case; only
an indication that, as specified above, the
air volume has reduced and the low pres-
sure has increased.
Anti-static system
Static charge is deflected by providing
earthing to the connection nozzles. This
way, the electrically conductive accesso-
ries approved by the manufacturer prevent
the formation of sparks and current surges.
Operation
WARNING
The two flat fold filters must never be re-
moved during vacuuming.
ATTENTION
Risk of damage! Do not cover the supply
and exhaust air openings on the suction
head.
Close the suction connection
WARNING
Health risk on account of fine dust! If the
suction hose is removed, the suction con-
nection must be closed.
Illustration
Properly insert the connection socket in
the suction connection.
Push in the connection socket until it
locks into place.
Note: The dirt container needs to be emp-
tied if it is filled until about 3 cm below the
upper rim or after every use.
– Check the fill level of the dirt container
at regular intervals, as the appliance
does not shut off automatically.
Dry vacuum cleaning
– The appliance is fitted with a disposal
bag, order no. 6.907-347.0 (5 ea.).
Note: You can use this appliance to take up
all types of dust up to dust class M. It is stat-
utorily necessary to use a dust collection
bag (see Filter systems for order number).
Note:The appliance is suited for sucking in
dry, combustible dusts with MAK values
greater than or equal to 0.1 mg/m
– To vacuum fine dust, you must use an
additional disposal bag.
Changeover from wet to dry vacuum
cleaning
ATTENTION
Please note the following when switch-
ing from wet to dry vacuum cleaning:
If you vacuum dry dust while the filter ele-
ment is still wet the filter will become ob-
structed and may be damaged beyond re-
pair.
Dry the wet filter properly before use or
replace it with a dry one.
Change the filter, if required, according
to instructions under the section "Main-
tenance and Care".
Installing the dust disposal bag
Lock parking brakes.
