The engine or certain components could be damaged
by high pressure washing systems; special
precautions must be taken if the engine is to be
washed using a high pressure system.
Ensure that the alternator, starter motor and any other
electrical components are shielded and not directly
cleaned by the high pressure cleaning system.

Important: Do not aim the water jet directly at bearings, oil
seals or electrical and electronic components such as the
engine electronic control unit (ECU), alternator or fuel
injectors.
Use a low pressure water jet and brush to soak off caked
mud or dirt.
Use a pressure washer to remove soft dirt and oil.
Note: The machine must always be greased after
pressure washing or steam cleaning.
