5.1.2 Picking up liquids

Do not pick up flammable
substances.
For safety reasons, an acoustic
warning sounds if the air speed
in the suction hose drops to be-
low 20 m/s. See section "Trou-
bleshooting".
If used correctly, additional ac-
cessories, suction nozzles and
suction hoses can enhance the
cleaning action and reduce the
cleaning effort.
The suction hose diameter must
suit the position of the switch in
order to pick up dry, nonflam-
mable dust with maximum room
concentration values.
There must always be a safety
filter bag in the tank before dry
substances with maximum room
concentration values are picked
up. See section 9.5 "Accesso-
ries" for ordering number.
To pick up harmless dust we
recommend the use of a waste
bag. See section 9.5 "Accesso-
ries" for ordering number. Dis-

posal of the picked up material
is then simple and hygienic.
After picking up liquids, the filter
element is wet. A damp filter el-
ement clogs more quickly when
dry substances are picked up.
For this reason the filter element
should be washed and dried or
replaced by a dry element be-
fore dry substances are picked
up.
Always use a filter bag/waste
bag that is suitable for the type
of dust (see table):
