Operating Instructions29HourmeterThe hourmeter displays operating time accumu-lated while the ignition switch is in the ON position.VoltmeterThe voltmeter displays battery and charging systemvoltage. An indication of low or high voltage (below11.5 volts or above 15.5 volts) indicates an electri-cal system failure. The cause of the failure shouldbe determined and corrected.Oil Pressure Warning LightThe oil pressure warning light indicates that engineoil pressure is below the safe operating range [below3 to 5 PSI (21 to 34 kPa)]. This light (and warninghorn) will come on when the ignition is turned ON, butshould go off after the engine is started. If the lightfails to come on when the ignition switch is turned ON,it could indicate a burned out bulb. If the light comeson during engine operation, stop the engine imme-diately and correct the source of the problem beforefurther engine operation.IMPORTANT: Continued operation of the enginewith an illuminated oil pressure warning light MAYcause severe engine damage (if a low oil pressurecondition exists).Over Temperature Warning LightThe over temperature warning light indicates thatengine oil temperature and/or cylinder head temper-ature are above the safe operating limit and the en-gine is overheating [above 305° F (152° C) oil or450° F (232° C) cylinder head]. If this light comeson, there may be a problem with:• Engine cooling system (material packed into cyl-inder head cooling fins, clogged air intake screen)• Low oil level in crankcaseStop the engine and correct the source of the prob-lem before further operation.IMPORTANT: Continued operation of the enginewith an illuminated over temperature warning lightMAY cause severe engine damage (if a high oil tem-perature or head temperature condition exists).Ignition SwitchThe ignition switch is used to start and stop the en-gine. The switch has three positions: “O” is the OFFposition, RUN is the position the key returns to afterstarting, and “S” is the START position. When start-ing the engine, turn the key clockwise to the “S” po-sition. Do not hold the key in the “S” position longerthan 10 seconds. If the engine does not start, returnthe key to the “O” position for at least 60 seconds be-fore making a restart attempt. Prolonged crankingcan damage the starter motor and shorten batterylife. Release the key when the engine starts, and itwill return to the “RUN” position. To stop the engine,rotate the key counterclockwise to the “O” position.Ignition SwitchLight Switch (For Optional Lights)Operates headlights (when installed).Warning HornThe warning horn sounds to alert the operator thatan unsafe engine condition is being indicated -when engine temperature is too high or engine oilpressure is too low. If the horn sounds, check theindicator lights and correct the problem before fur-ther operation.ONOFFSTART
