7.2 Cleaning of nozzle A clogging up in the noz-
zle causes a pump pressure
which is too high. This is
why cleaning is required
immediately.
1. Stop the machine and
disconnect the nozzle.
2. Clean the nozzle. IM-
PORTANT: The cleaning
tool (11) should only be
used when the nozzle is
detached!
3. Flush the nozzle back-
wards 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 coup-
lings
To ensure an easy connec-
tion and that o-rings do
not dry up, the couplings
should be greased regu-
larly.
