1.- Engine
For operation instructions, a list of spare parts and for general maintenance consult the
engine manual or the LUBRICATION AND MAINTENANCE CHART of this Manual.
 Alternator belt
Periodically check the tension in the alternator belt. Also check for cracks or other
damage. Contact an AUSA dealer for replacement of the alternator belt.
2.- FUEL CIRCUIT
Current regulation in regard to exhaust emissions demands that the values of the exhaust
emission components are kept below the maximum limits authorised by the regulations
throughout the useful life of the machine. Consequently, the engine maintenance plan
must be carefully followed, with special attention given to the quality and purity of the
fuel used, to the cleaning of filters and generally to the maintenance of the complete fuel
circuit.
CAUTION:
Never mix oil with fuel. This vehicle has a 4-stroke engine. Oil must be added to the
engine base only.
Use automotive clean diesel (class A), which preferably meets 98/70/CEE standard
amended by standard 2003/17 or the equivalent EN 590 standard.
In Spain RD 1728/1999 applies.
For the USA market, it must meet Grades 1D and 2D of the ASTM D975 standard, in
supplies which do not meet these standards, the sulphur content should never exceed
0.5% mass.
In principal, the use of REM type biodiesel or similar is not recommended. In case of use,
the proportion used should not exceed 5% of the fuel mix.
 Fuel level (fig. 1, 2)
The fuel tank is located on the right side of the engine compartment.
There is an indicator dial which shows the approximate amount of fuel in the tank.
a. Fuel level indicator dial.
b. Fuel filling cap.
 Draining water from the filter element (fig. 3)
The fuel used in this vehicle may contain water which is deposited at the bottom of the
filter element. It is vitally important for the protection of the engine injection system to
drain the water from the filter element at the frequency indicated in the LUBRICATION
AND MAINTENANCE CHART.
Loosen the drain (c) located at the bottom of the filter. Wait until all water has been
released and retighten the drain.
WARNING!!
Take care to correctly loosen the drain (c) otherwise the fuel system could take in air
causing engine failure.
