Cleaning the Machine
Introduction
T3-062_2
Clean the machine using water and or steam. Do not allow
mud, debris etc. to build upon the machine.
Before carrying out any service procedures that require
components to be removed:
1 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.
2 When cleaning is complete move the machine away
from the wash area, or alternatively, clean away the
material washed from the machine.
Important: 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.
Detergents
Avoid using full strength detergent - always dilute
detergents as per the manufacturer's recommendations,
otherwise damage to the paint finish may occur.
Always adhere to local regulations regarding the disposal
of debris created from machine cleaning.

!MCAUTION
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.
