DESCRIPTION Oil Pressure Gauge This gauge (located on the instrument panel) shows whether lubricating oil is circulating through the engine. The indicator needle should be past the first mark above zero when the engine is running at speeds approx* imately 100 r.p.m. above slow idle speed. See Illust. 7. If the needle does not move past the first mark above zero, stop the engine immediately and investigate the cause of the oil pressure failure. If you are unable to find the cause, consult your International Harvester dealer before operating tbe engine. lIIust. 7 Oil pressure gauge. IIlm.7A Tachometer. which provides a means of setting the exact engine speed specified for power rake-off operations. A mark on the lower haH of the dial indicates a power take-off shaft speed of 537 r.p.m. at 1450 engine r.p.m. Tachometer Refer to the table on page 19 for normal ground speeds according to tire sizes. Refer to "Power Take-Off Specifications" on page 23 for power take-off speeds. This instrument records engine bours of opera- tion, shows normal tractor speeds in miles per hour in all forward gears, and indicates the engine r.p.m. Before Starting Your New Tractor Before starting the engine for the lirst time, remove the spark plugs and put about one teaspoonful of crankcase oil into each cylinder; replace the spark plugs and crank the engine to distribute the oil over the cylinder walls. This assures positive lubrication of the cylinders and pistons immediately after starting and eliminates the possibility of scoring. Lubrication Tractors shipped to destinations in the United States of America, Canada, and Mexico have the crankcase and air deaner filled with SAE-lOW oil from October 15 to April 15, and SAE-20 oil from April 15 to October 15. If the engine is to be operated at tem- peratures for which these oils are recommended (see the "Lubrication Table"), this oil can be used in the engine 150 hours operation. If temperatures are not within the range specified, drain the oil crankcase and air deaner, and replace it with the required amount of fresh oil having the physical properties and proper viscosity suitable for the prevailing temperature and type Lubricate the entire tractor, using the "Lubrica- tion Guide." Check the oil levels of the engine crankcase, air deaner, transmission, belt pulley housing, and aU gear cases to see that they are fmed to the correct levels with oil of the proper viscosity for the p r e v a n ~ ing temperatttte. See the "Lubrication Guide" and the specifications ollubdcants on pages 31 atui j2. service. Tractors pad(ed for export have aU oil drained from the engine crankcase, air cleaner and aU gear cases. 1

DESCRIPTION Fuels having a lower than 83 octane rating can be used satisfactorily in distillate burning engines. These engines are designed for use with fuels having a 40 minimum nctane rating. Fuels having a less than 40 octane rating should be used in kerosene burning engines. See the chart below fnr fuel octane ratings r ~ quired tn obtain the best engine performance and maximum engine life for your type of engine. Pneumatic: Tires Before moving the tractor, check the air pressure in the pneumatic tires and inllate or de1late the front and rear tires to the correct operating pressures. See the table on page 76. Rear Wheels Before operating the tractor. check the rear wheel hub damp bolts to make certain that they are torqued to 390-440 ft. Ibs. Tighten the rear wheel hub clamp bolts a l t e r n a t e ~ ly and a little at a time to prevent excessive tension at any location. Type of Engine Fuel OCtl!.ne Gasoline burning 83 and up Distillate burning 40 to 83 Steel Wheels If your tractor is equipped with steel wheels, or has new wheel and lug installations. it is advisable to check and tighten the rear wheel bolts at intervals to he sure that the lugs seat properly. Kerosene burning Below 40 To obtain hest results. use the fuel for which the tractor is designed, follow the operating instructions given for that fuel and observe the following pre- cautions: Use clean fuel and keep it dean. Store fuel in tanks equipped with hose and nozzle to pre- vent contamination of the fuel. The use of funnels, cans and drums is not recommended because they are difficult to keep dean. Distillate fuels should conform to Interna- tional Harvester Company specifications (see yout International Harvester dealer). On distillate or kerosene-burning tractors, do not open the shut-off valves under the auxiliary tank and under the main fuel tank, or even partially open them, at the same time. as this will permit the distillate or kerosene to mix with the gasoline, making the engine hard to start. During the first 100 hours of operation. mix one pint of light engine oil with every five U.S. gallons of fuel. Engine Cooling System The cooling system capacity is approximately 27% U. S. quarts. Be sure the radiator drain and craflkcase water drain (I11Ilst. 45) are dosed; then fill the radiator to a level apprnximately 27.i inches below the top of the filler neck. Filling the radiator to this level will allow for expansion of the coolant under normal operating conditions. Use dean water; soft or rain water is recommended, as it does not contain alkali. which forms scale and eventually dogs the passages. Never start or operate the engine without water or antifreeze in the cooling system except as instructed in "Cold Weather Precautions" on page 43. For further information see "Cooling System" (page 44). If the tractor is to be operated in freezing temperatures (+ 32 <> F. or lower) see "Cold Weather Precautions" on page 43. Fuel System Provision is made in the design of this tractor so that it may be equipped with either a gasoline, d i s ~ tillate, or kerosene-burning engine. Before attempt- ing to use a fuel for which your tractor is not designed. see your International Harvester dealer or the nearest International Harvester Company District Office for full details. International Harvester gasoline burning engines are specifically designed for use with regular grade gasoline having an 83 minimum octane rating (re- search method). Battery-to-Ground Cable Tractors shipped from the factory with starting and lighting equipment have the battery-tn-ground cable disconnected and taped. Therefore, before attempting to start the engine, be sure the battery-to- ground cable is connected to the ground.

DESCRIPTION Preparing Your Tractor For Each Day s Work Fuel System Iliust.9A Never refuel the tractor while the en!line is funning or extremely hot. Filling the fuel tank. Fill the fuel tank (capacity 2172 U. S. gallous) preferably at the end of eacb day's work. This will fnrce out any moisture-laden air and prevent con- densation. funnel and container in contact with the metal of the fuel tank (Ilias!. 9A) to avoid the possibility of an electric spark igniting the gas. Do not light matches near gasoline, as the air within a radius of several feet is mixed with a higbly explosive vapor. Tractors designed for distillate or kerosene oper- ation have an auxiliary tank (capacity ~ for gasoline. which is used only for starting and warming up the engine. If a distillate or kerosene engine is to be operated on gasoline only, use the large fuel tank for gasoline and eitber sbut off the small tank or use it as an auxiliary tank. U.S. gallon) Cooling System Remove the radiator filler cap and check the water level. Fill to a level approximately below the top of the filler neck. inches Tbe filler caps on both fuel tanks have air vents. These vents shnuld be kept open at all times to assure proper flow of the fuels. See Illnst. 9.
