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

Class A-1
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 SC160B1002-0EN
Issued 02-07
1002-7 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.

Contents The engine speed, work mode, and boosted pressure state are switched by the throttle volume. With auto / one-touch switchover function Runs the engine at low idle speed when it starts up. In order to prevent the engine from stalling, during operation, raises the low idle speed to the auto idle speed. If the coolant temperature is low, warm-up operation is executed automatically when the engine starts Judgment based on engine speed from ECM When key ON OFF, 4-second delay; when engine running OFF, 7-second delay When the emergency stop switch is pressed, the ECM recognizes this and stops the engine. Engine start load (cell not turning) when lever locked Linked with the throttle, the SP / H / A mode is switched over and the pump horsepower is controlled. The pump horsepower milli-amp is raised when there is a high load or sharp load. The pump horsepower milli-amp is reduced by the transient load control, engine stall prevention control, and PID control conditions. The negative control relief pressure for non-operation is varied and the negative control pressure is lowered to reduce the pump load. When the upper and swing are not operated, the swing brake is operated automatically and during travelling too Swing option for North America There is a swing lock function (for servicing) with monitor operations. When a swing starts, the flow is reduced with the front side proportional valve and the excess oil is eliminated. Travel speed low-speed / high-speed switchover Buzzer sounded (for 10 seconds) during travel Operation is not possible unless the gate lever is raised. When key ON, solenoid switched ON / OFF for 0.25 second. The computer automatically raises the pressure from 34.3 MPa (433 bar / 4975 psi) => 36.8 MPa (368 bar / 5338 psi) when necessary.

Operation explanation: a) Auto / one-touch switchover function The operator can switch between one-touch and auto by pressing the auto idle switch on the monitor in the figure below. When auto idle is ON, the LED at the side of the switch lights up.
b) Auto idle control (A) 1. When auto idle is set, if the lever is left continuously unoperated for 5 seconds, the engine speed automatically becomes the auto idle speed (1200 min-1). This five-second setting for auto idle operation is the default value. This setting can be changed to from 1 to 30 seconds with service support operations. 2. When the lever is operated, the engine speed is automatically returned to the engine speed set for the throttle volume. 3. Even with auto idle set, it is p ossible to move to auto idle or return from auto idle by pressing the knob switch (one-touch idle switch) on the right operation lever. c) One-touch idle control When auto idle is no t set, regardless of lever operation, it is po ssible to move to auto idle or r eturn from auto idle by pressing the knob switch (one-touch idle switch) on the right operation lever. The idling speed for one-touch idle control is 1000 min-1 on CX160B to CX240B and 900 min-1 on CX290B.

4001-12 d) Idling speed 1. Auto idling speed => 1200 min-1 2. One-touch idling speed => 1000 min-1 on CX160B to CX240B and 900 min-1 on CX290B. 3. Low idling speed => 1000 min-1 on CX160B to CX240B and 900 min-1 on CX290B. The speeds above are the default values. They can be set to from 900 to 1600 min-1 with service support operation (See Screen Operation in Ser vice Support). However, the settings are based on the following conditions. Low idle speed = One-touch idle speed ≤ Auto-idle speed (The one-touch idle speed and auto-idle speed settings can be changed).
3. Idling Start
a) When the engine starts, the engine speed becomes the low idle speed regardless of the throttle position. b) When the low idle speed is changed, the engine speed is controlled at this new speed. c) During an idling start, the idling icon (A) is displayed at the top left of the monitor. No message is displayed
.
d) An idling start is ended in the following cases and control becomes normal. 1. When the one-touch idle switch is pressed 2. When the throttle volume is operated 3. When the operation lever is operated (upper, travel, swing, arm-in pressure sensor ON) e) Back-up operation 1. Sensor trouble If trouble occurs in a sensor (upper, travel, swing, arm-in), the idling start is ended. 2. Throttle volume trouble Even if the throttle volume is operated, the idling start is not ended. Also, even if the idling start is ended with some other method, the throttle cannot be adjusted. 3. One-touch idle switch trouble Even if the switch is pressed, the idling start is not ended.
