Maintenance & Care
Cleaning Function
Use the cleaning function if the
nozzle is blocked. Turn the unit off
using button 5 (Standby).
Remove the water filter at first. (For
its instructions see paragraph
above.) Fill the tank with distilled
water. Close the tank and put it
back into the unit. Adjust the
amount of spray regulator knob (6)
on maximum. Now press icon
<Clean> in the display under Select
Menu. The complete cleaning
process will last three minutes and
then switches off by itself. If
requested, you could cancel the
process by pushing button (5).
During the cleaning process, the
water will be washed out of the
whole spray system. Parts of dirt
are rinsed into the tank. Do not use
this water again but clean the tank
immediately
after
realizing
a
blockage in the nozzle. Otherwise
the dirt parts might stick together.
Clean the water filter carefully and
put it back in the adapter. Refill the
tank with new water.
Use the cleaning function
only if the nozzle is blocked.
Do not use the function if
the unit works properly.

performance of the handpiece.
Therefore, clean the chuck monthly.
How to remove the chuck

handpiece and the top with the
brush.

the axle and hold it tight. Now use
the front of the second spanner to
