Clean
Notice: Clean the engine before you start engine maintenance. Obey the correct procedures.
Contamination of the fuel system will cause damage and possible failure of the engine.
Notice: 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
engine air intake, alternator, starter motor and any other electrical components are shielded and not directly
cleaned by the high pressure cleaning system.
Before carrying out any service procedures that require components to be removed, the engine must be
properly cleaned.
Cleaning must be carried out either in the area of components to be removed or, in the case of major work, or
work on the fuel system, the whole engine and surrounding machine must be cleaned.
Stop the engine and allow it to cool for at least one hour. Do not attempt to clean any part of the engine while
it is running.
1. Make sure that the electrical system is isolated.
2. Make sure that all electrical connectors are correctly coupled. If connectors are open fit the correct caps
or seal with water proof tape.
3. Cover the alternator with a plastic bag to prevent water ingress.
4. Seal the engine air intake, exhaust and breather system.
5. Make sure that the oil filler caps and dipstick are correctly installed.
6. Use a low pressure water jet and brush to soak off caked mud or dirt.
7. Apply an approved cleaning and degreasing agent with a brush. Obey the manufacturers instructions.
8. Use a pressure washer to remove the soft dirt and oil. Important: Do not aim the water jet directly at oil
seals or electrical and electronic components such as the ECU (Electronic Control Unit), alternator or fuel
injectors. Do not place the jet nozzle closer than specified to any part of the engine.
Length/Dimension/Distance: 600mm
9. When the pressure washing is complete move the machine away from the wash area, or alternatively, clean
away the material washed from the machine.
10. Before working on specific areas of the engine use a compressed air jet to dry off any moisture. When the
area is dry use a soft clean brush to remove any sand or grit particles that remain.
11. When removing components be aware of any dirt or debris that may be exposed. Cover any open ports
and clean away the deposits before proceeding.
Oil
Check (Level)
WARNING Never check the oil level or add oil with the engine running. Be careful of hot lubricating oil.
Danger of scalding.
Notice: Do not exceed the correct level of engine oil in the sump. If there is too much engine oil, the excess
must be drained to the correct level. An excess of engine oil could cause the engine speed to increase
rapidly without control.
1. Make the machine safe.
