[2] FUEL SYSTEM INSPECTION PROCEDURE

Fuel:
Fuel is flammable and can be dangerous.
You should handle fuel with care.
• Cetane Rating: The minimum recommended Fuel Cetane Rating is 45.
A cetane rating greater than 50 is preferred, especially for ambient temperatures below –20 °C (–4 °F) or
elevations above 1500 m (5000 ft).
• Diesel Fuel Specification Type and Sulfur Content % (ppm) used, must be compliant with all applicable emission
regulations for the area in which the engine is operated.
• DO NOT USE Fuels that have sulfur content greater than 0.0015 % (15 ppm).
• Diesel fuels specified to EN 590 or ASTM D975 are recommended.
• No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
• These engines utilize Interim Tier 4 standards, the use of ultra low sulfur fuel is mandatory for these engines,
when operated in US EPA regulated areas.
Therefore, please use No.2-D S15 diesel fuel as an alternative to No.2-D, and use No.1-D S15 diesel fuel as an
alternative to No.1-D for ambient temperatures below −10 °C (14 °F).

2. EN: European Norm
3. ASTM: American Society of Testing and Materials
4. US EPA: United States Environmental Protection Agency
5. No.1-D or No.2-D, S15: Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.%
IMPORTANT
• Be sure to use a strainer when filling the fuel tank, or dirt or sand in the fuel may cause trouble.
• Do not run the fuel tank level too low or completely out of fuel. Additionally, fuel system bleeding may be
necessary if air enters the fuel system.
Biodiesel fuel:
[When the B7 blended fuel is used]
When the finally blended Biodiesel fuel is B7, make sure it conforms to the updated EN590 (European) standard.
Be also sure that the mineral oil diesel fuel, if used, conforms to the updated EN590 (European) standard and that
the B100 blend conforms to the updated EN14214 (European) standard.
[When the B5 blended fuel is used]
When the finally blended Biodiesel fuel is B5, make sure it conforms to the updated EN590 (European) standard.
Be also sure that the mineral oil diesel fuel, if used, conforms to the updated EN590 (European) standard or the ASTM
D975 (U.S.) standard and that the B100 blend conforms to the updated EN14214 (European) standard or the ASTM
D6751 (U.S.) standard.
