DIESEL FUEL SYSTEM Use No. 2 diesel fuel in the engine of this machine. The use of other fuels can cause the loss of engine power and high fuel consumption. In very cold temperatures, a mixture of No. 1 and No. 2 diesel fuels is temporarily permitted. See the following Note. NOTE: See your fuel dealer for winter fuel requirements in your area. If the temperature of the fuel lowers below the cloud point (wax appearance point), wax crystals in the fuel will restrict the fuel filter and cause the engine to lose power or not start.

Fuel Storage If you keep fuel in storage for a period of time, you can get foreign material or water in the fuel storage tank. Many engine problems are caused by water in the fuel. Keep the fuel storage tank outside and keep the fuel as cool as possible. Remove water from the storage container at regular periods of time. Fill the fuel tank at the end of the daily operating period to prevent condensation in the fuel tank.

The diesel fuel used in this machine must meet the specifications as shown below in, “Specifications for Acceptable No. 2 Diesel Fuel”, or “Specification D975-81” of the American Society for Testing and Materials.

Specifications for Acceptable No. 2 Diesel Fuel API gravity, minimum ............................................................................................................................................. 34 Flash point, minimum ............................................................................................................................60°C (140°F) Cloud point (wax appearance point), maximum ...........................................................-20°C (-5°F) See Note above Pour point, maximum ..................................................................................................-26°C (-15°F) See Note above Distillation temperature, 90% point ................................................................................282 to 338°C (540 to 640°F) Viscosity, at 38°C (100°F) Centistokes ......................................................................................................................................... 2.0 to 4.3 Cetane number, minimum .......................................................................... 43 (45 to 55 for winter or high altitudes) Water and sediment, by volume, maximum ..................................................................................................... 0.05%

What is Selective Catalytic Reduction (SCR)? The main components of the SCR system include the SCR catalyst, the Diesel Exhaust Fluid (DEF)/ AdBlue® injection unit, the DEF/AdBlue® tank, and the DEF/AdBlue® dosing control unit.

How does Selective Catalytic Reduction (SCR) work? During combustion, harmful Nitrogen Oxide (NOx) molecules are formed in the exhaust. By injecting a DEF/AdBlue® solution into the exhaust prior to a catalyst, the NOx can be converted to harmless elemental Nitrogen and water. This happens when the NOx molecules react inside the catalyst with the heat generated by the engine and the ammonia in the DEF/AdBlue® solution. During cold engine operation at low engine coolant and ambient air temperatures, water vapor will be visible from the exhaust when the engine operates. This water vapor will resemble steam or light white smoke and will dissipate as the engine and machine components warm and is considered normal. NOTE: After engine shutdown, the SCR system will perform a purge cycle, which permits the supply module to continue to run for up to 70 seconds. This is to be considered normal and requires no action from the operator.

What is Diesel Exhaust Fluid (DEF)/AdBlue®? DEF/AdBlue® is a non-toxic aqueous urea solution ( 3 2 .5 % ) w i th a s l i g h t a m m o n i a o d o r u s e d to chemically reduce NOx emissions from heavy-duty diesel powered vehicles. DEF/AdBlue® is neither explosive nor harmful to the environment and is classified under the minimum-risk category of transpor table fluids. DEF/AdBlue® quality is defined by ISO 22241-1. The American Petroleum Institute (API®) has a voluntary certification program for DEF/AdBlue®. To ensure DEF/ AdBlue® satisfies the requirements of ISO 22241. DEF/AdBlue®. API Diesel Exhaust Fluid Certification Mark is a registered trademark of API in the United States and or other countries.

Storage, handling, and transport NOTICE: Storage temperatures above 30 °C (86 °F) greatly reduce the shelf life of DEF/AdBlue®. DEF/AdBlue® has a typical shelf life of 6-12 months. Refer to the SHELF LIFE table below. In order for DEF/AdBlue® to remain in a usable condition, storage requirements need to be met.

• Store between -11 °C (12 °F) and 30 °C (86 °F). • Use only an approved DEF/AdBlue® container.

• Keep container tightly closed. • Keep container in a cool, well-ventilated area. • Keep away from heat and direct sunlight. Thawing • The machine is equipped with an internal tank heater to thaw frozen DEF/AdBlue®. The machine will still function until the DEF/AdBlue® begins to flow. The SCR system will then function normally. • Do not heat DEF/AdBlue® for long periods of time at temperatures above 30 °C (86 °F). This causes the solution to decompose, which very slowly decreases the expected shelf life. NOTICE: Do not use an anti-gelling or freeze point improver in your DEF/AdBlue®. The 32.5 % solution is specifically designed to provide the optimum NOx reduction properties. Any further blending or adjusting of the DEF/AdBlue® mixture will lessen its ability to perform correctly and may cause damage to the SCR components. Handling and supply of additives, if any. • Personal Protective Equipment (PPE) is not required under normal conditions. If splashing is likely, wear eye protection. For prolonged or repeated contact, imper vious gloves are recommended. Follow the precautions listed in the SAFETY INFORMATION chapter when handling any service fluid. • No additives are required. NOTICE: Contaminated DEF/AdBlue® can affect the performance of your machine. Follow all instructions in this manual when handling DEF/AdBlue®.

Shelf life Constant ambient storage temperature and minimum shelf life Less than or equal to 10 °C (50 °F) 36 months Less than or equal to 25 °C (77 °F) ¹ 18 months Less than or equal to 30 °C (86 °F) 12 months Less than or equal to 35 °C (95 °F) 6 months Greater than 35 °C (95 °F) -² ¹ To prevent decomposition of DEF/AdBlue®, prolonged transportation or storage above 25 °C (77 °F) should be avoided. ² Significant loss of shelf life: check every batch before use. See your [Brand] dealer for more information on testing.


1002-8 NOTE: The main factors taken into account to define the shelf life in the previous figures are the ambient storage temperature and the initial alkalinity of DEF/AdBlue®. The difference in evaporation between vented and non-vented storage containers is an additional factor. NOTE: The information in this table is for reference only and has been provided by the International Organization for Standardization, Document number ISO 22241-3 Diesel engines - NOx reduction agent AUS 32 - Part 3: Handling, transportation and storage. Disposal • Dispose of DEF/AdBlue® and any filter accumulations in accordance with all applicable Federal, State, and local laws governing waste disposal. For machines sold in California CNH must warrant the diesel emission control system in the application for which it is sold or leased to be free from defects in design, materials, workmanship, or operation of the diesel emission control system which cause the diesel emission control system to fail to conform to the emission control performance level it was verified to, or to the requirements in the California Code of Regulations, Title 13, Sections 2700 to 2706, and 2710, for the periods of time listed below, provided there has been no abuse, neglect, or improper maintenance of your diesel emission control system, vehicle or equipment, as specified in the owner’s manuals. Where a warrantable condition exists, this warranty also covers the engine from damage caused by the diesel emission control system, subject to the same exclusions for abuse, neglect or improper maintenance of your vehicle or equipment. Please review your owner’s manual for other warranty information. The diesel emission control system may include a core part (e.g., particulate filter, diesel oxidation catalyst, selective catalytic reduction converter) as well as hoses, connectors, and other emission-related assemblies.

SELECTIVE CATALYTIC REDUCTION (SCR) - BASIC INSTRUCTIONS Requirements The operator must maintain appropriate DEF/AdBlue® levels at all times. The SCR system is compatible with up to 7% bio-diesel fuel.

Diesel Exhaust Fluid (DEF)/AdBlue® refilling The DEF/AdBlue® tank cap (1) can be identified by the “blue” color of the cap. A fitting under the cap prevents the insertion of a diesel fill nozzle. NOTE: If any DEF/AdBlue® spills or contacts any surface other than the storage tanks, immediately clean the affected surface with clear water. DEF/AdBlue® will cause corrosion on painted and unpainted metallic surfaces, and may distort some plastic and rubber components. It i s r e c o m m e n d e d t h a t D E F /A d B l u e ® f i l l i n g equipment should be used having a fill nozzle/pump with the correct length and diameter, triggered by the magnet in the tank filler neck and with overfill flow cut out. This will ensure that: ●

The screen in the filler neck will not be damaged.

Impurities are not entering the DEF/AdBlue® tank. The standardized DEF/AdBlue® nozzle matches the filler neck diameter.

The DEF/AdBlue® tank is not overfilled, as the DEF/AdBlue® pump will stop when the DEF/AdBlue® tank is full.

DEF/AdBlue® is not pumped in the fuel tank, as the DEF/AdBlue® nozzle cannot pump when the magnet is not sensed. NOTICE: Refilling with a funnel is not recommended as this may lead to damage of the screen in the filler neck. NOTE: The information above has been provided by the International Organization for Standardization (ISO), Document number ISO 22241-4 Diesel engines - NOx reduction agent AUS 32 - Part 4: Refilling interface.

Diesel Exhaust Fluid (DEF)/AdBlue® consumption NOTE: DEF/AdBlue® consumption is highly dependent on engine loads, humidity levels, DEF/AdBlue® fluid concentration, and engine speed. The “typical” consumption is only a guideline to verify proper function of the SCR system. CNH recommends to fill the DEF/AdBlue® tanks at every fuel refilling interval.
