Maintenance & Care
Washer
The top of the handpiece is
equipped with a washer (art. 4571).
This washer has to be replaced by a
new one
every 2 weeks (25
operation hours) . Unless
exchanging it, spray liquid could
enter the handpiece and cause of
damages of the internal parts.
Exchanging the washer:
Unscrew the top of the handpiece.
Pull out the washer with tongs. If any
particles of the washer remain,
remove them. Push the new washer
in the top. Please pay attention to
the way it was installed. Screw the
top onto the handpiece tip.
Filter
Even smallest parts of dirt could
block the nozzle, which sits in the
top. Avoiding such blockages, there
is a spray liquid filter (art. 3497)
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.
Rinse it quite regularly.
Exchanging the water filter:
Take off the cap of the tank. Hold the
metal piece (A) and unscrew the
filter (B). Now you can screw the
new filter.
