Section 5 - General Maintenance
5A - General Knowledge
:
The vehicle will remain in good operating condition as long as the correct maintenance and operating procedures are followed.
During maintenance, the vehicle should be parked on a level dry surface with the park-brake in the
‘ON’
position; this is to
ensure the vehicle does not move.
Note:
If the vehicle operates under extreme conditions, (such as bad roads, thick dust
condition and frequent stop start operations), the maintenance interval should be reduced accordingly. Carefully clean all
surrounding areas before adding fluids or changing parts.
5B - Cleaning the vehicle:
Be careful not to pollute or damage the environment when washing the vehicle.
Ensure the correct concentrations of cleaning detergents are used.
DO NOT wash the vehicle in direct sunlight.
ENSURE water is not directed onto or into the air intake system as this can cause extensive engine damage.
DO NOT spray high pressure water onto the radiator fins; or any Electronic Control Unit (ECU).
5C - Maintaining the engine:
For up to date and correct engine maintenance information, please refer to the engine Supplier’s Operation Handbook. For
cleaning, steam is the best method for an engine and its components. ENSURE that all electrical components such as ECU’s,
alternators, starters, openings, wiring and terminals are protected from the full force of the cleaner spray nozzle. If steam is not
available, use a solvent.
WARNING
: Use protective clothing to avoid risk of serious injury.
5D - Cleaning the radiator:
Keep the outside of the radiator clean to enable a good air flow to pass through it.
Use compressed air or water to clean the outside of the radiator. If there is hard scale on the radiator, steam can be used to
blow and clean both sides. DO NOT USE HIGH PRESSURE CLEANERS ON THE RADIATOR FINS, WHICH MAY CAUSE
DAMAGE.
5E – Coolant:
Note: ONLY the coolant recommended by the engine manufacturer MUST be used in the cooling system.
5F - Rotation of the tyres
(figure 29):
To assist with tyre life, it is suggested to periodically rotate the RADIAL tyres according to the diagram below:
