1.2 General safety instructions
The provisions of the relevant accident prevention regulations of the appropriate
employer's liability insurance association are to be observed any time operation and
repair work is carried out. In addition, the following is to be observed:
• Seals made of VITON
R
have been used at various locations in the engine. With normal
engine operation this material is completely harmless, however it should not be expo-
sed to temperatures above 300 °C, since above 325 °C a thermal decomposition and the
formation of hydrofluoric acid can occur.
• Replaced seals should be disposed of immediately, and above all, it should be taken
care that this material is not overheated even by accident e.g. during combustion and
welding operations. If this should however has happened, the gases emitted must not
be inhaled. Skin contact with decomposed VITON
R
is to be avoided at all times. After a
fire with VITON
R
, it is essential that neoprene gloves are worn during the clearing up
operations.
• Any residues have to be neutralized before their disposal, i.e. saturated with calcium
hydroxide.
• Maintenance and repair work must only be carried out by skilled and authorized
personnel!
• Use personal protective equipment as far as necessary or as required by the
regulations!
All texts marked with this symbol in the maintenance sheets are safety
instructions which have to be observed in all cases in order to eliminate
danger to life and limb of the user or of third parties!
