Fuel Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard.

Use grade No. 2-D fuel. The use of other types of fuel can result in a loss of power of the engine and may cause high fuel consumption.

In cold weather (below -7°C), it is provisionally approved to use a mixture of fuels No. 1-D and No. 2-D. If the temperature falls below the fuel cloud point (point at which wax begins to form) the wax crystals will cause power loss or will prevent the engine from starting.

Required conditions for diesel fuel The following specific conditions are required for diesel fuel: - Must be free from minute dust particles.

- Must have adequate viscosity.

- Must have high cetane value.

- Must have high fluidity at low temperature.

- Must have low sulphur content.

- Must have little residual carbon.

Diesel fuel recommendation - JIS (Japanese Industrial Standard) : No. 2 - DIN (Deutsche Industrie Normen) : DIN 51601 - SAE (Society of Automotive Engineers) Based on SAE-J-313C: No. 2-D - BS (British Standard) Based on BS/2869-1970: Class A-1 IMPORTANT : If fuel other than the specified one is used, engine operation will be impaired.

Using fuels other than those recommended can damage the fuel injection pump, the injector and other parts of the fuel supply system and the engine. CASE disowns any responsibility concerning this kind of damage, which is not covered by the guarantee. To avoid any damage to the engine fuel supply system, you are recommended to take the following safety messages into account: Some fuel suppliers mix used engine oil with diesel fuel. Certain manufacturers of large engines allow them to do this. However, for your engine, do not use diesel fuel contaminated by engine oil. In addition to damaging the engine, this fuel can actually adversely affect the correct purification of exhaust gases. Before using any diesel fuel, ask the supplier if this fuel has been mixed with engine oil.

IMPORTANT : For use of the correct fuel additives, consult your oil or lubrication supplier. Do not inject fuel oil or gasoline, both fuels can damage the engine.

IMPORTANT : In cold weather, fill the fuel tank at the end of the day's work, in order to prevent the formation of condensation.

Fuel storage Long storage can lead to the accumulation of impurities and condensation in the fuel. 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.

Lep 9-94170EN

1002-7

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, 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 any maintenance operation on this machine and before disposing of used fluids or 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 centre 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.
