Maintenance & Care
Washer
The top of the handpiece is
equipped with a white washer (art.
no. 4571). This washer has to be
replaced by a new one
every 50
operation
hours
,
unless
exchanging it, water could enter the
handpiece and cause of damages
of the internal parts. You will
receive a message in case it has to
be changed.
Exchanging the washer
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.
Push the new washer in the top.
Confirm the washer change (see
page 21).
Water Filter
Even smallest parts of dirt could
block the nozzle, which sits in the
top. Avoiding such blockages, there
is a water 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.
Changing the water filter
Take off the cap of the tank. Hold
the metal piece (A) in one hand and
screw off the water filter (B).
Now you can screw on the new filter
(art. no. 3497).
