OPERATING INSTRUCTIONS

PREPARATION OF A NEW ENGINE

Before placing a new or rebuilt engine in service, make a thorough visual inspection for evidence of damage or loose parts.

ENGINE OIL. See that the crankcase contains the correct amount of clean new SAE 1OW Engine Oil.

COOLING SYSTEM. Fill the cooling system with water, using anti-freeze solution, if temperature requires it. In warm weather, the use of MOPAR Rust Resistor is recommended.

CAUTION

Before any type of permanent anti-freeze is added to the engine coolant, the cylinder head bolts must be tightened to 85 foot-pounds torque. Failure to do so may result in extensive damage to the engine.

ENGINE ACCESSORIES. See that all points requiring lubrication are properly supplied. Check storage battery terminals to see that they are tight and clean. Check the electrolyte in the battery.

ELECTRICAL CONNECTIONS. See that all electrical connections are tight and clean. Check each spark plug for tightness.

ATTACHING PARTS. See that all nuts, bolts and screws that attach parts are secure.

PRESTARTING INSTRUCTIONS

When the engine is in daily use, inspect it daily, always before starting.

ENGINE OIL LEVEL. Inspect the oil level and add oil of proper viscosity if required.

FUEL. Check the fuel supply.

COOLING SYSTEM. Inspect the cooling system and add water or antifreeze, as required.

TIPS ON ENGINE CARE

NEW OR REBUILT ENGINES. It is good practice not to operate a new or rebuilt engine at more than 3/4 throttle for the first 8 to 10 hours. This low speed will permit the bearings to seat properly, and will allow the operator to familiarize himself with the controls and performance of the engine.

No. 1OW Engine Oil should be used in the engine during the break-in period because the clearance between moving parts is very small and the light oil provides assured lubrication. Keep the oil at the proper level. After 25 hours of operation, the crankcase should be drained and refilled with oil as recommended in the Lubrication Section.

COLD ENGINES. When starting a cold engine (whether new or not), avoid unnecessary acceleration during the warm-up period. Keep the throttle at little more than idling speed until normal operating temperature is indicated on the temperature gauge. This simple precaution will assure long life of the engine and maximum efficiency of operation.

STARTING AND STOPPING THE ENGINE

STARTING. Open the throttle to 1/3 opening. See that the clutch, gear shift lever or power take-off lever is in neutral position. Turn on the ignition switch and press the starting motor switch until the engine starts. Do not hold the starting motor switch in for periods longer than 15 seconds if the engine does not start promptly. After the engine starts, watch the oil pressure gauge. If oil pressure does not register after about 10 seconds, stop the engine and investigate.

STOPPING. To stop the engine, close the throttle and disengage the clutch. Allow the engine to run at idle speed for a few minutes. Close the throttle and turn off the ignition.

PRECAUTIONS

WARM-UP PERIOD. After starting a cold engine, operate it at a speed only slightly faster than idle (approximately 700 rpm) for a few minutes to allow the engine to reach normal operating temperature before placing it under full load. This warm-up period will permit oil to reach all bearing surfaces, thus reducing the possibility of scoring and premature wear of internal engine parts.

OIL PRESSURE. With engine turning at approximately 2000 rpm and the water temperature at 160 degrees F., the oil pressure should be from 45 to 55 pounds. As bearings wear and the increased clearances permit more than the normal escape of oil, there will be a drop in pressure shown on the gauge, particularly at idling speed. A drop in oil pressure may also be the result of a plugged oil filter element.

WATER TEMPERATURE. A thermostat (Fig. 16) in the cylinder block restricts the circulation of liquid in the cooling system until the liquid has reached a pre-determined temperature, thereby permitting faster warm-up of the engine. Do not operate the engine with the thermostat removed as this unit is essential to proper circulation and efficient engine performance. Without the thermostat, sludge will form in the crankcase, because the low temperature of the engine permits condensation of fumes in the crankcase. When operating in hot climates, the maximum reading of the temperature gauge should not exceed 100 degrees F. above the prevailing atmospheric temperature.

AIR CLEANERS. Remove and service the carburetor and oil filler cap and crankcase ventilator outlet air cleaners every 50 hours or less, depending on the severity of working conditions. Operating in dusty areas will require daily service of air cleaners.

IGNITION SYSTEM. Keep the units of the ignition system clean and properly adjusted.

FUEL SYSTEM. Keep the fuel tank, lines and filters clean. Always use a good grade of fuel.

COOLING SYSTEM. Do not fill the cooling system when the engine is overheated. Allow the engine to cool before adding liquid, in order to prevent cracking the cylinder blocks. Use a good grade of MOPAR anti-freeze during cold weather, and MOPAR Rust Resistor during warm weather.

POWER TAKE-OFF AND CLUTCH ASSEMBLY. On units equipped with the Power Take-Off and Clutch Assembly, avoid unnecessary use of the shifting lever. Frequent engagement and disengagement of the clutch causes rapid wear of clutch facings, necessitating frequent adjustment and replacement of parts. Do not attempt to engage or disengage the clutch while the engine is accelerated. Do not operate the unit when the clutch is slipping. See Adjustment Section.
