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 (10)
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.
7.1 Cleaning of water inlet
fi lter
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 l-
ter will invalidate the guarantee.
Clean the water inlet fi lter
regularly once a month or more
frequently according to use.
