ZERO EMISSION CITY BUS Owner’s
Manual
5A - General Knowledge
：
Section 5 - General Maintenance
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 batteries:
For up to date and correct battery maintenance information, please refer to the battery Supplier’s Operation Handbook.
NOTE: If the vehicle is parked for a long period, more than a month, the batteries should be fully charged. It is
recommended batteries are recharged every two months. This is to balance the voltage of each cell.
5D – Motor and Inverter cooling system:
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 battery manufacturer MUST be used in the cooling system.
5F - Rotation of the tyres
(figure 25):
To assist with tyre life, it is suggested to periodically rotate the RADIAL tyres according to the diagram below:
