7.1  Cleaning of water inlet  

 fi lter

Clean the water inlet fi lter 
regularly once a month or more 
frequently according to use. 
Carefully loosen the fi lter with a 
screwdriver and clean it. Check 
that it is intact before re-mount-
ing it. 

The inlet fi lter must always be 
fi tted inside the water inlet pipe 
to fi lter out sand, limestone and 
other impurities, as they will 
damage the pump valves.

CAUTION: 

Failure to fi t the fi lter 

will invalidate the guarantee.

7.2 Cleaning of nozzle 

A clogging up in the nozzle 
causes a pump pressure which 
is too high. This is why cleaning 
is required immediately.
 
1. Stop the machine and dis-

connect the  nozzle. 

2. Clean the nozzle.

 IMPOR-

TANT: 

The cleaning tool (11) 

should only be used when 
the nozzle is detached!

3. Flush the nozzle backwards 

with water.

7.3  Cleaning of machine  

vents

The machine should be kept 
clean so as to let cooling air 
pass freely through the ma-
chine vents.

7.4 Greasing of couplings
 

To ensure an easy connec-
tion and that o-rings do not dry 
up, the couplings should be 
greased regularly.

z

 Make sure that no sand or 

dirt is blocking the movement 
of the pawl on the Click & 
Clean spray lance. Rinse ac-
cording to requirement.

z

 Rinse the detergent spraying 

attachment after use.

z

 Clean the nozzles.

Any repair should always be 
made in an  authorized work-
shop with original spare parts.
