Operating Instructions36HourmeterThe 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 (the redarea) indicates an electrical system failure. Thecause of the failure should be determined and cor-rected.Oil Pressure Warning LightThe oil pressure warning light indicates that engineoil pressure is below the safe operating level [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 Light(Model MT and MTEFI Only)The 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).Water Temperature Warning Light (Model MTL)The water temperature warning light indicates thatengine coolant temperature is above the safe oper-ating limit and the engine is overheating. If thislight comes on, there may be a problem with:• Radiator cooling air flow (material packed into radi-ator cooling fins, clogged air intake screen)• Cooling fan not operating• Low coolant quantity in cooling systemWater Temperature Gauge (Model MTL)The water temperature gauge monitors enginecooling system temperature. If engine coolanttemperature exceeds 230° F (110° C), an overheatcondition exists; the water temperature light willcome on and the warning horn will sound.Engine Service Light - Model MTEFIThe engine service light indicates the Engine Con-trol Unit (ECU) has detected a fault in the engineperformance. When this light illuminates during op-eration, contact an authorized Kohler Service dealerto diagnose the fault.IMPORTANT: Continued operation of the enginewith an illuminated engine service light will result insub-standard performance and MAY cause enginedamage if not corrected as soon as possible.WARNINGIf engine cooling system overheating isindicated, continued operation of the en-gine, even for a short time, COULD resultin fire, risk of personal injury, and severedamage to equipment.
