Please pay attention to the notes in chapter „5. Installation“ and
chapter „7. Maintenance“.

The threads (G) of the tip inserts must be coated with high tempe-
rature installation paste (see chapter „5.3.1 Tools and operating ma-
terials“.

Installation temperature 220°C.

Non-standard tip inserts may require tightening torques which dif-
fer from the values given here. In case of doubt always contact

EWIKON.
