Fire hazards

The main switch of the battery has a main power emergency button to disconnect
the battery immediately if needed. The red-coloured push button is located below
the right fender fuse and relay board. The emergency off switching can be done
only when the ignition key is turned to the Off position.
Using the main power emergency button causes uncontrolled battery
disconnection. For example, the AdBlue urea lines are not emptied properly and
electrical control unit operating data has not been saved as designed.

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.
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.
WARNING: Never burn viton seals.
