Engine fuel, maintenance of fuel filters and fuel storage In order to meet the emission control regulation of 3rd-stage, the engine components have been made precisely and they are to be used under high-pressure conditions. Therefore, the specified fuel must be used for the engine. As a matter of course, not only the guarantee will not be given for the use of a fuel other than the specified but also it may invite a serious breakdown. In addition, since suitable specifications for the fuel filter elements have been established for this engine, use of the genuine filter is essential. The following describes the specifications and the requirements of the fuel to be applied, and maintenance of the fuel and the fuel elements.

Fuel to be applied Selection of fuel Following conditions must be met for the diesel engines, that is the one; 1 In which no dust even fine one is mixed, 2 With proper viscosity, 3 With high cetane rating, 4 With good flow properties in lower temperature, 5 With not much sulfur content, and 6 With less content of carbon residue Applicable standards for diesel fuel Applicable Standard

EN590 If a standard applied to the fuel for the diesel engine is stipulated in your country, check the standard for details. Requirements for diesel fuel Although conditions required for the diesel fuel are illustrated above, there are other requirements exerting a big influence on its service durability and service life. Be sure to observe the following requirements for selecting fuel. Sulfur content............................................................................... 2500 ppm or less HFRR*.......................................................................................... 460 mm or less Water content............................................................................... 0.05 wt% or less * HFRR (High-Frequency Reciprocating Rig.): An index showing lubricating properties of the fuel. Sulfur content reacts to moisture to change into sulfuric acid after combustion. Use of a fuel containing much sulfur content allows it to accelerate internal corrosion and wear. In addition, much sulfur content quickens deterioration of engine oil allowing its cleaning dispersive property to be worse which results in acceleration of wear of sliding portions. HFRR is an index that indicates lubricating property of a fuel. Large value of the index means poor lubrication so that seizure of the machine components may result if such a fuel is used. Since a fuel with high HFRR value also has lower viscosity, it can easily be leaked out. Lep SC4601002-0EN

Issued 03-07


1002-9 If the fuel is mixed with the engine oil, the oil is diluted to deteriorate its lubricating property resulting in acceleration of wear. Water content allows inside of the fuel tank to rust which in turn blocking the fuel line and the fuel filter. IMPORTANT : In cold weather, fill the fuel tank at the end of the day's work, in order to prevent the formation of condensation. This may also cause wear and seizure of the machine components. If atmospheric temperature goes below the freezing point, moisture content in the fuel forms fine particle of ice allowing the fuel line to be clogged. IMPORTANT : Obtain table of analysis for the fuel you are using from the fuel supplier to confirm that it meets the criteria described above. IMPORTANT : If a fuel which does not meet the specifications and the requirements for the diesel engine, function and performance of the engine will not be delivered. In addition, never use such a fuel because a breakdown of the engine or an accident may be invited. Guarantee will not be given to a breakdown caused by the use of a improper fuel. Some fuels are used with engine oil or additives mixed together with diesel engine fuel. In this case, do not use these fuels because damage to the engine may result as the fuel has been contaminated. It is natural that the emission control regulation of 3rd-stage will not be cleared in case where a fuel that does not meet the specifications and the requirements is used. Use the specified fuel for compliance of the exhaust gas control. IMPORTANT : It you use diesel fuel which contains much sulfur content more than 2500 ppm, be sure to fol- low the items below for the engine oil selection and maintenance of engine parts. Guarantee will not be given to breakdowns caused by not to follow these items. 1 Selection of engine oil Use API grade CF-4 or JASO grade DH-1. 2 Exchange the engine oil a nd engine oil f ilter element by the periodical interval reported on t he Operator’s Manual. 3 Inspect and exchange the EGR (*)parts and fuel injector parts of engine every 3000 hour of use. * EGR: Exhaust Gas Recircultion

Maintenance of fuel filters Be sure to use the genuine fuel filters. The fuel injection system is precisely constructed and the genuine filter employs finer mesh than conventional filters to improve protection of machine equipment. If a filter with coarse mesh is used, foreign object passing through the filter enters into the engine so that machine equipment can wear out in a short period of time. IMPORTANT : If a fuel filter other than the genuine filter is used, guaranty will not be applied to a fault caused by the use of a wrong filter. Two kinds of fuel filter, the pre-filter and the main filter, are mounted on the machine. Be sure to use the genuine fuel filters and replace them at the periodic intervals reported on the operator’s Manual. IMPORTANT : Since the pre-filter also has a function of water separation, discharge water and sediment when the float reaches lower part of the filter elements. CHECK EVERY DAY before to start the engine. Time to replace filters may be advanced according to properties of the fuel being supplied. • Therefore, take measures to prevent dust or water from being entered in the fuel tank when sup- plying fuel. • When supplying fuel directly from a fuel drum can, leave the drum as it stands for a long period of time to supply clean fuel standing above a precipitate. • If it is hard to leave the drum for a long period of time, install a fuel strainer and a water separator before the fuel tank of the machine to supply clean fuel. Water drain cock is provided on the bottom side of the fuel tank. • Drain water before starting the engine every morning. • In addition, remove the cover under the tank once a year to clean up inside of the tank.

Fuel storage Long sto rage ca n le ad to t he accum ulation of im purities and cond ensation in t he f uel. Engine trouble can often be traced to the presence of water in the fuel. The storage tank must be placed outside and the temperature of the fuel should be kept as low as possible. Drain off water and impurities regularly.

Anti-freeze/Anti-corrosion Use anti-freeze in all seasons to protect the cooling system from corrosion and all risk of freezing. CASE/AKCELA: PREMIUM ANTI-FREEZE (MS 1710) For areas where the temperature goes down to -38°C (-36.4°F), mix 50/50 with water. IMPORTANT : Do not mix products of a different origin or brand. The same product must be used when topping up the system.

Environment Before carrying out a ny maintenance o peration on t his ma chine an d b efore disposing o f used f luids o r lubricants, always think of the environment. Never throw oil or fluid on the ground and never place it in leaking receptacles. Contact your local ecological recycling ce ntre or your CASE Dealer to obtain information on the correct method of disposing of these lubricants.

Plastic and resin parts When cleaning plastic parts, the console, the instrument panel, the indicators etc... avoid using petrol, kerosene, paint solvents etc... Use only water, soap and a soft cloth. The use of petrol, kerosene, paint solvents etc... causes discoloration, cracks or deformation of these parts.

Based on the information, ECM sends electric signals to supply pump and to injector to make a proper control of fuel injection quantity and injection timing for each cylinder. 1) Injection quantity control Based mainly on engine speed and load given to actual machine, Injection rate control is carried out for optimum injection by controlling fuel injector. 2) Injection pressure control Injection pressure is controlled by control of fuel pressure in the common-rail. The right pressure in the common-rail is calculated by using engine speed and fuel injection quantity. The supply pump and the pressure control valve are controlled according to the calculated pressure so that it can discharge proper quantity of fuel to pressure-feed into the common-rail for control. 3) Injection timing control The control substitutes timer function and an appropriate fuel injection timing is calculat ed by mainly using engine speed and fuel injection quantity to control the injector. 4) Injection rate control In order to improve fuel consumption in the cylinder, a sm all amount of fuel is inject ed (pre injection) for ignition at first, then 2nd time injection (main injection) into the ignited cylinder is carried out. In this control, the injection quantity control in section 1) and the injection timing control in section 3) are carried out by controlling injector.
