Note! The oil volume is approx. 125
litres, so be prepared to replace the

oil with a viscosity of ISO VG 32 and an
oil heater accessory is recommended.
The recommended oil under normal
conditions is ISO VG 46 (with the oil
temperature no more than 60°C).

the new oil to the tank through
the opening of filler cap A (approx.
125 litres).
