If used correctly, additional ac-
cessories, suction nozzles and 
suction hoses can enhance the 
cleaning action and reduce the 
cleaning effort.

Effective cleaning is achieved if 
you follow just a few guidelines 
in combination with your own 
practical experience in special 
fields.

Here are some basic tips.

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.

Before liquids are picked up, al-
ways remove the filter bag/waste 
bag and check that the float (IVB 
3-H) or the water level limit (IVB 
5-H/7-H) works properly. (See 
section 7.2.3 and 7.2.4 “Replac-
ing the filter element“.)

The use of a separate filter ele-
ment or filter screen is recom-
mended.

If foam appears, stop work im-
mediately and empty the tank.

To reduce the amount of foam, 
use foam killer Nilfisk-Advance 
Foam Stop (see section 9.5 
„Optional Accessories“ for order 
number).
