5.1 Techniques	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.

5.1.1 Picking up dry	CAUTION:
substances	Do not pick up flammable
	substances.
	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.

5.1.2 Picking up liquids	CAUTION:
	Do not pick up flammable
	substances.
	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).
