CAUTION!
1. In order to ensure a long-term and reliable operation of the engine, use only certi-
fied diesel fuel grades. Try to avoid the ingress of water and foreign matter into the
fuel.
2. In case of welding operations at the tractors with Mercedes engines, it is necessary
to disconnect the power wires “+” and “-” from storage batteries (wires 1 and 7, see
the wiring diagram). Connect wire terminals between each other by means of M10
bolt with nut. When connecting storage battery to the electric circuit, first connect "+",
then "-". Non-fulfilment of this requirement can lead to a failure of the engine electron-
ic control system.
