Note (1):
All nonroad Tier 4 Final and EU Stage V diesel engines are required to use: – Ultra low sulfur diesel (ULSD) fuels containing 15 ppm (mg/kg) sulfur or less. – Cat engines are compatible with the following renewable, alternative, and biodiesel* fuels that reduce greenhouse gases***: • Up to B20 biodiesel (FAME)** • Up to 100% HVO and GTL renewable fuels – Cat DEO-ULS™ or oils that meet the Cat ECF-3, API CJ-4, and ACEA E9 specifications are required. – Diesel exhaust fluid (DEF) that meets all requirements defined in ISO 22241-1:2006. * Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. ** Engines with aftertreatment devices can use up to B20. Engines with no aftertreatment devices can use higher blends, up to B100. *** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
Air Conditioning System
Air Conditioning:
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. - If equipped with R134a (Global Warming Potential = 1430), the system contains 1.9 kg of refrigerant which has a CO2 equivalent of 2.717 metric tonnes.
