– Remove the upper part by moving it forwards 

horizontally,

– Empty  the  dirt  container,
– Replace the upper part. 

 Make sure 

that both upper-part pins are fully inserted in 
the recesses (1.5)!

– Close the vacuum cleaner.

Before using the vacuum cleaner to evacuate dry 
substances, a fi lter bag must always be inserted 
in the container. Then the evacuated material can 
be disposed of easily. 

The fi lter element becomes damp after evacuating 
liquids. A damp fi lter element suffers more wear 
and tear if it is used for dry materials. Accordingly, 
the fi lter element should be dried or replaced with 
a dry one before dry operation.

 Do not evacuate combustible liq-

uids! 

 If foam or liquid escapes, stop work 

immediately and empty the dirt container. 

 The HEPA fi lter element shall only be 

used for extracting dry materials.

The fi lter bag has to be removed before evacuat-
ing liquids. We recommend use of a special wet 
fi lter (452924). 

When the maximum fi lling level is reached, a 
bag-full indicator (2.12) automatically interrupts 
extraction.

 During the following procedure, take 

care not to raise dust more than is unavoidable. 
Moisten the fi lter element with a water spray be-
fore removing it. 

Check the fi ll level of the fi lter bag at regular 
intervals. A full fi lter bag shall be replaced im-
mediately. 

Check the fi lter element for damage every time 
the fi lter bag is changed. Replace damaged fi lter 
elements immediately. 

Always insert a fi lter bag when using a HEPA fi lter 
element.
