  INTRODUCTION Basic instructions Coolant solution Putonly ethylene-glycol coolant solution in the cooling system. Use good quality ethylene-glycol that has a high boiling point with no additives to prevent leakage. Do not use non-approved anti-rust additives. Anti-rust additives and ethylene-glycol can mix and work against each other, reducing anti-corrosion protection, forming deposits in the cooling system, and causing damage to the cooling system and radiator. Contact your Dealer who can supply you with the suitable coolant solution. Anti-freeze/Anti-corrosion Use anti-freeze in all seasons to protect the cooling system from corrosion and risk of freezing. For areas where the ambient temperature is over -36 °C (-32.8 °F) use a blend of 50% ethylene-glycol based anti-freeze. For areas where the temperature is below -36 °C (-32.8 °F) - it is advisable to use a blend of 40% water and 60% anti-freeze. Fuel Use diesel fuel suitable for the ambient temperature conditions ( ASTM D975). Use fuel which is to ASTM (American Society for Testing and Materials) D975 standard (North America). In Europa, fuel must comply with specification standard EN 590 or ITS EQUIVALENT. Use grade No. 2 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 very low ambient temperatures, use a mixture of fuels No. 1 and No. 2 as necessary. Consult your fuel supplier for appropriate fuel supply. 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. In cold weather, fill the fuel tank at the end of the day's work in order to prevent the formation of condensation. Engine oil NEW HOLLAND AMBRA UNITEK CJ-4 ENGINE OIL SAE 15W-40 is recommended for your engine. This oil insures correct lubrication of your engine in all working conditions. See General specification () to choose the correct oil for climate/temperatures. If NEW HOLLAND AMBRA UNITEK CJ-4 ENGINE OIL SAE 15W-40 cannot be obtained, use only oil of the API CI4 category. NOTE: Do not put any performance additive or other ad- ditive in the sump. Oil change intervals shown in this manual are based on tests carried out utilizing NEW HOL- LAND CONSTRUCTION lubricants. LELI12WL30004AA 1 Fuel storage Prolonged storage of fue l 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. 84547255C 15/03/2013 9

  INTRODUCTION Hydraulic fluid NEW HOLLANDAMBRA HYDROSYSTEM 46 HV is specifically designed for high pressure applications and for NEW HOLLAND CONSTRUCTION hydraulic systems. Your NEW HOLLAND CONSTRUCTION Dealer can provide hy- draulic fluid to fulfill different climate/temperature conditions. Refer to the General specification (). Transmission component oil Extreme pressure oil should be used for enclosed transmission components. Choose an oil that is manufactured for your climate/temperature conditions such as NEW HOLLAND AMBRA MULTI G 134™ HYDRAULIC TRANSMISSION OIL. See General specification (). Grease The type of grease to use depends on ambient temperature such as: NEW HOLLAND AMBRA GR 75 MD. Environment Before you service this machine and dispose of oil, fluids, and lubricants, obey environmental regulations. Do not drain oil or fluids on to the ground or into containers that leak. Check with your local environmental, recycling center or your Dealer for correct disposal information. 84547255C 15/03/2013 10
