Handling viton seals subjected to high temperatures

At temperatures over 300°C, the viton seals of the engine produce highly
corrosive hydrofluoric acid.
Do not touch viton seals subjected to abnormally high temperatures with your
bare hands.
Use neoprene rubber or heavy duty gloves and safety glasses when
decontaminating.
Wash seals and the contaminated area with 10% calcium hydroxide or other
alkali solution.
Put all the removed material in sealed plastic bags and deliver them to the
point stated by the authorities concerned.

After-treatment system

The selective catalytic reduction (SCR) after-treatment system contains
vanadiumpentoxide. Vanadiumpentoxide can be hazardous to health.
The SCR after-treatment system is installed in the muffler, and is not hazardous
to health under normal use and handling.
DANGER: If the tractor engine is running, do not leave anybody in the
cab without supervision, as the push buttons are easily operated.
Always apply the parking brake.
DANGER: You may be held responsible for any resulting accidents.
WARNING: Open fire, smoking and sparks are prohibited near the fuel
system and batteries. Especially when charging batteries, explosive
gases are present.
