Clean the ceramic part (2), replace if necessary.
Note:
Note the locating pins on the ceramic part when doing this – they must engage into
the sensor insert.
The nozzle and the nut must only be tightened by hand
(do not use any tools)
.
Otherwise the ceramic part could be damaged. In addition to this, make sure
that the contact surfaces on these parts are clean.
Attention – Laser beam position!
Check the beam path each time the nozzle is replaced. The laser beam must
be in the centre of the nozzle.
To avoid any damage, do not obstruct the laser beam.
