Cleaning the cooling spray nozzles
If your tap water is very hard, lime deposits may constrict or
completely block the cooling spray nozzles.
ATTENTION! During preparation work, a sufficient
amount of cooling media (water component > 50 ml/min)
must always be available. Insufficient cooling leads to over-
heating of the cavity and to damage to the tooth substance.
We therefore recommend cleaning the nozzles on a regular
basis. To do this, gently push the cleaning wire (1) through
the nozzle openings.
Then briefly operate the highspeed handpiece with cooling
spray.
