Maintenance & Care
Washer
The top of the handpiece is
equipped with a white washer (art.
4571). This washer has to be re-
placed by a new one
every four
weeks
, unless exchanging it, spray
liquid could enter the handpiece
and cause a lot of damages of the
internal parts.
Screw off the top of the handpiece.
Pull out the washer with some
tongs. Look for little parts of the
washer in the top and around. If you
find some, remove such eventually.
Please pay attention to the way it
was installed. Push the new washer
in the top.
Spray Liquid Filter
Even smallest parts of dirt could
block the nozzle, which sits in the
top. Avoiding such blockages, there
is a spray liquid filter installed in the
cap of the tank. We recommend to
change this every time, when it is
covered with some dirt, at least
twice a year. Still make sure, no
parts of dirt enter the tank and rinse
it quite regularly.
Take off the cap of the tank. Hold
the metal piece (A) in one hand and
screw off the spray liquid filter (B).
Now you can screw on the new
filter.
