CAUTION
Seals made of VITONR have been used at various locations in the engine.
With normal engine operation this material is completely harmless, however it
should not be exposed to temperatures above 300 °C, since above 325 °C a
thermal decomposition and the formation of hydrofluoric acid can occur.
CAUTION
Maintenance and repair work must only be carried out by skilled and autho-
rized personnel!
NOTE
Any residues have to be neutralized before their disposal, i.e. saturated with
calcium hydroxide.
Clean the engine parts, especially connections and threaded unions of any
traces of oil, fuel or preservatives before carrying out maintenance/repair (di-
sassembly, assembly)!
Never use aggresive detergents and preservatives!
Use non-fuzzy cleaning rags!
Observe all indicating labels attached to the engine!
