5 Applications and techniques
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
elds.
Here are some basic tips.
CAUTION!
Do not pick up ammable
substances.
Before picking up dry sub-
stances, always ensure that a
lter bag is inserted in the tank
(see section 9.5 "Accessories"
for order number). Disposal of
the picked up material is then
simple and hygienic.
After picking up liquids, the lter
element is wet. A damp lter
element clogs more quickly
when dry substances are
picked up. For this reason the
lter element should be washed
and dried or replaced by a dry
element before dry substances
are picked up.
5.1.2 Picking up liquids
CAUTION!
Do not pick up ammable
liquids.
Always remove the lter bag
and check the oater before
picking up liquids (see sec-
tion 7.2.3 "Replacing the lter
element").
The use of a separate lter ele-
ment or lter screen is recom-
mended.
If foam appears, stop work im-
mediately and empty the tank.
To reduce the amount of foam,
use foam killer Alto Foam Stop
(see section 9.5 "Accessories"
for order number).
