WARNING
Do not vacuum without the filter elements; otherwise,
the suction motor can get damaged and this can be haz-
ardous to health on account of increased release of fine
dust particles.
Bring the appliance to working position - secure it,
if required, with parking brakes.
Insert the suction hose (not included) into the suc-
tion hose connection.
Check the fill level in the dirt container prior to start-
ing work and empty the container if necessary.
Ensure that the dirt container has been inserted
properly.
Attach the desired accessories (not included).
Automatic monitoring of suction capacity
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.
Note: The control lamp can light up occasionally during
normal operation (e.g., while working with a floor noz-
zle), if the air volume comes down (cross-sectional re-
duction) causing a low pressure.
Note: There is no defect in this case; only an indication
that, as specified above, the air volume has reduced
and the low pressure has increased.
Anti-static system
Static charge is deflected by providing earthing to the
connection nozzles. This prevents the formation of
sparks and current shocks due to attachments (option)
with electrical conductivity.
CAUTION
The flat pleated filter must always be in place while vac-
uuming.
Close the suction connection
WARNING
Health risk on account of fine dust! If the suction hose is
removed, the suction connection must be closed.
Illustration
Properly insert the connection socket in the suction
connection.
Push in the connection socket until it locks into
place.
Turn the suction connection with the connection
socket to the right to close it tightly.
Note: The accurate fit is ensured by means of a "bayo-
net connection".
Note: The dirt container needs to be emptied if it is full
until about 3 cm below the upper rim.
–
Check the fill level of the dirt container at regular in-
tervals, as the appliance does not shut off automat-
ically.
Dry vacuum cleaning
–
The device is equipped with a dust bag, order no.
9.989-607.0 (5 pieces).
Note: You can use this appliance to take up all types of
dust up to dust class M. It is statutorily necessary to use
a dust collection bag (see Filter systems for order num-
ber).
Note:The appliance is suited as industrial vacuum
cleaner to take up dry, non-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.
CAUTION
Please note the following when switching from wet
to dry vacuum cleaning:
If you vacuum dry dust while the filter element is still wet
the filter will become obstructed and may be damaged
beyond repair.
Dry the wet filter properly before use or replace it
with a dry one.
Change the filter, if required, according to instruc-
tions under the section "Maintenance and Care".
Installing the dust disposal bag
Lock parking brakes.
Illustration
Remove the pressure balancing at the upper end.
Pull the locks of the placement mechanics up.
Pull the push handle upward. The container is un-
locked and lowered.
Illustration
Pull the container out by the handle.
Illustration
Insert the disposal bag so that it is snug against the
reservoir wall and the reservoir bottom.
Pull disposal bag over the container.
Reinsert the container and lock it with the push
handle.
