1 - GENERAL INFORMATION Foreword Ecology and the Environment Soil, air, and water are vital factors of agriculture and life in general. When legislation does not yet rule the treatment of some of the substances which are required by advanced technology, common sense should govern the use and disposal of products of a chemical and petrochemical nature. NOTICE: The following are recommendations which may be of assistance: • Become acquainted with and ensure that you understand the relative legislation applicable to your country. • Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, antifreeze, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use and dispose of these substances. • Agricultural consultants will, in many cases, be able to help you as well. HELPFUL HINTS • Avoid filling tanks using cans or inappropriate pressurized fuel delivery systems which may cause considerable spillage. • In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances which may be harmful to your health. • Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems. • Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc. Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed of in a proper way to comply with local legislation and available resources. • Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil but should be collected and disposed of properly. • Do not open the air-conditioning system yourself. It contains gases which should not be released into the at- mosphere. Your NEW HOLLAND AGRICULTURE dealer or air conditioning specialist has a special extractor for this purpose and will have to recharge the system properly. • Repair any leaks or defects in the engine cooling or hydraulic system immediately. • Do not increase the pressure in a pressurized circuit as this may lead to a component failure. • Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, allowing the loss of oils, coolant, etc. 1-2 NOT FOR REPRODUCTION
1 - GENERAL INFORMATION General specification - Biodiesel Fuels Fatty Acid Methyl Ester Biodiesel (Biodiesel Fuel) con- sists of a family of fuels derived from vegetable oils treated with methyl esters. NOTICE: Biodiesel Fuel blends are approved for your en- gine only if they comply with EN14214 Specification Stan- dards or ASTM D6751. NOTICE: It is imperative that you check which blend is ap- proved for your engine with your NEW HOLLAND AGRI- CULTURE dealer. Be aware that the use of Biodiesel Fuel that does not comply with the Standards mentioned above could lead to severe damage to the engine and fuel sys- tem of your machine. The use of fuels that are not ap- proved may void NEW HOLLAND AGRICULTURE War- ranty coverage. Biodiesel Fuel Usage Conditions NOTICE: The Biodiesel Fuel must meet the fuel Specifi- cation mentioned above. Biodiesel Fuel must be purchased from a trusted sup- plier that understands the product and maintains good fuel quality. Biodiesel Fuel must be pre-blended by the supplier. Mixing Biodiesel Fuels on-site can result incor- rect mixture that can lead to problems with both engine and fuel system. Engine performance is affected by the use of Biodiesel Fuel. There may be up to 12 % reduction in power or torque depending on the blend used. NOTICE: DO NOT modify the engine and/or injection pump settings to recover the reduced performance. The reduced power must be accepted if using any Biodiesel Fuel blend. Some modification may be required to allow your engine to run Biodiesel Fuel. Consult you dealer for complete information on these modifications. Biodiesel Fuel has a higher cloud point than Diesel Fuel. NOTICE: The use of high Biodiesel Fuel blends are not recommended in cold weather conditions. With Biodiesel Fuels, it may be necessary to change the engine oil, engine oil filter and fuel filter elements more frequently than with Diesel Fuels. Biodiesel Fuel can re- move rust and particles from the inside of on-site fuel storage tanks that would normally adhere to the sides of the tank. Like particle deposits that commonly occur with Diesel Fuel, these particles can become trapped by the machine fuel filters, causing blockage and shortening filter life. In cold weather, this is more likely to happen. Consult your NEW HOLLAND AGRICULTURE dealer for information on cold weather operation and proper main- tenance intervals when using any Biodiesel Fuel blend. When handling Biodiesel Fuel, care must be taken not to allow water into the fuel supply. Biodiesel Fuel will actu- ally attract moisture from the atmosphere. Fuel tanks must be kept as full as possible to limit the amount of air and water vapors in them. It may be nec- essary to drain the fuel filter water tap more frequently. Potential oxidation and stability could be a problem with the fuel stored in the machine. NOTICE: Machines must not be stored for more than three months with Biodiesel Fuel blends in the fuel sys- tem. If long storage periods are necessary, the engine must run on Diesel Fuel for 20 hours to flush the Biodiesel Fuel out of the engine fuel system prior to storage. NOTICE: Biodiesel Fuel must not be stored in on-site stor- age tanks for more than three months. Any spillage of Biodiesel Fuel must be cleaned up imme- diately before it can cause damage to the environment and the paint finish of the machine. Before using Biodiesel Fuel blends you should consult with your dealer to receive full information about the ap- proved blend for your machine and any detailed condi- tions of its usage. NOTICE: Be aware that not fulfilling the requirements and conditions of Biodiesel Fuel usage will void your ma- chine’s NEW HOLLAND AGRICULTURE Warranty cov- erage. 1-3 NOT FOR REPRODUCTION
