BEFORE STARTING A rJEW TRACTOR GENERAL The operator must be thoroughly aCQIBinted with the position and operation of all instruments and controls regardless of previous experience. DO NOT ATIEMPT TO START THE ENGINE OR DRIVE THE TRACTOR UNTIL THE FOLLOWING POINTS HAVE SEEN CHECKED. SHIP-AWAY OILS Tractors received factory filled will contain an SAE-20 oil in the engine crankcase. aircleaner and hydraulic system. and an SAE-90EP oil in the transmis- sion. The oil in the crankcase may be used for the first 25 hours of operation if the tractor is to be operated in ambient temperatures between oOC (+32OF) and +32OC( +90OF). If the embient temperature is not within this range. drain the oil fran the crankcase and aircleaner. change the oil filter element then fill with the grade of oil specified in the LUBRICATION GUIDE for the prevailing temperature. AFTER THE FIRST 25 HOURS OF OPERATION THE OIL FILTER ELEMENT AND CRANKCASE OIL MUST BE CHANGED. 'The hydraulic oil suction strainer must be removed and cleaned after the first 25 hours of operation. first 200 hours of operation and first 500 hours of operation of a new tractor. The hydraulic oil need not be changed at these periods provided it is free from contamination but must be changed after 1000 hours of operation. If the tractor is to be operated in an ambient temperature outside the range OOC (+32tlf) to +320C (+90Of) the hydraulic oil must be drained and the system filled with the grade of oil specified in the LUBRICATION GUIDE for the prevai ling temperature. The transmission oil may be used for the first 1000 hours of operation if the tractor is to be operated in ambient temperatures between OOC (+32oF) and +320C (+90Of). If the ambient temperature is not within this range drain the transmission oil then fill with the grade of oil specified in the LUBRICATION GUIDE for the prevailing temperature. LUBRICA TION Check all levels and lubricate the entire tractor referring to the LUBRICATION GUIDE for the correct lubricants to be used. AIRCLEANER Ensure that the aircleaner is intact and undamaged. tighten all connections securely. NEVER OPERATE THE ENGINE WITH THE AIRClEANER REMOVED OR ANY PART DISCONNECTED. COOLING SYSTEM Never start or operate the engine without first checking that the radiator is fi lied to the correct level. Factory filled COOling systems will contain a solution of I.H. inhibitor ant i-freeze and water. This solution wi II protect the cooling system against freez ing in temperatures as low as -34OC (+300F) and in addition the inhibiting additives will prr obtain maximum b ~ ; from these inhibitors. it is recommended that I.H. inhibitor anti -freeze solut ion is used a II year round. Every two years. change the SOlution , r ~ the interior of the system from corrosion. In order to
