Fuel
WARNING Do not use petrol in this machine. Do not mix petrol with the diesel fuel. In storage tanks the
petrol will form flammable vapours.
Notice: No warranty liability will be accepted for engine failures where unacceptable fuel grades (or their
equivalent) have been used at any stage.
Acceptable and Unacceptable Fuels
Use the same type of diesel fuel as used in cars (EN 590 for E.U. - ASTM D975-09B regulation - S 15 for U.S).
Use of other types of fuel could damage the engine. Do not use dirty diesel fuel or mixtures of diesel fuel and
water since this will cause serious engine faults.
Clean fuel prevents the fuel injectors from clogging. Immediately clean up any spillage during refuelling.
Never store diesel fuel in galvanized containers (i.e. coated with zinc). Diesel fuel and the galvanized coating
react chemically to each other, producing flaking that quickly clogs filters or causes fuel pump and/or injector
failure.
Fuels for Low Temperatures
When operating the engine in ambient temperatures lower than 0°C (32.0°F), use suitable low temperature
fuel normally available from fuel distributors and corresponding to the specifications in the table.
These fuels reduce the formation of paraffin in diesel at low temperatures.
When paraffin forms in the diesel, the fuel filter becomes blocked interrupting the flow of fuel.
Biodiesel Fuel
Fuels containing 10% methyl ester or B10, are suitable for use in this engine provided that they meet the
specifications listed in the table.
Do not use vegetable oil as a biofuel for this engine.
Any failures resulting from the use of fuels other than recommended will not be warranted.
