operation manual for more information.
Biodiesel blends up to 5% (B5) are approved for use in this unit. The fuel used must meet the

are taken. Extra attention is needed when using biodiesel, especially when operating in cold weather or

Avoid static electricity when fueling. Ultra Low Sulfur Diesel (ULSD)
poses a greater static ignition hazard than earlier diesel formulations. Avoid death or
serious injury from fire or explosion. Consult with your fuel system supplier to ensure the
delivery system is in compliance with fueling standards for proper grounding and bonding
practices.
NOTICE: Use only Ultra Low Sulfur Diesel (less than 15 ppm (15 mg/kg) sulfur content) in this unit.
Operating with higher sulfur content will damage the engine and aftertreatment device.
IMPORTANT: Worldwide, fuel sulfur regulations vary widely. Fuel used should always comply with local
regulations. Prior to shipping, Tier 3 units were filled with API CJ-4 DEO. If operating fuel with sulfur
content above 500 ppm (500 mg/kg), change oil initially at 100 hours.
