SAFETYNOTICEThe safety messages that follow haveNOTICE level hazards.It is important to perform daily checks aslisted in the Operation Manual.Periodic maintenance prevents unexpecteddowntime, reduces the number of accidentsdue to poor engine performance and helpsextend the life of the engine.See your authorized Yanmar Marine dealeror distributor if you need to operate theengine at high altitudes. At high altitudes theengine will lose power, run rough andproduce exhaust gases that exceed thedesign specifications.ALWAYS be environmentallyresponsible.Follow the guidelines of the EPA or othergovernmental agencies for the properdisposal of hazardous materials such asengine oil, diesel fuel and engine coolant.Consult the local authorities or reclamationfacility.NEVER dispose of hazardous materials bydumping them into a sewer, on the groundor into ground water or waterways.If a Yanmar Marine Engine is installed at anangle that exceeds the specifications statedin the Yanmar Marine Installation Manuals,engine oil may enter the combustionchamber causing excessive engine speed,white exhaust smoke and serious enginedamage. This applies to engines that runcontinuously or those that run for shortperiods of time.If you have an installation with two or threeengines and only one engine is operating,the seacock of the non-running engine(s)should be closed. This will prevent waterfrom being forced past the seawater pumpand entering the engine. The result of waterentering the engine could cause engineseizure or other serious problems.If you have an installation with two or threeengines, and only one engine is operating,please note that if the propeller shaftthru-hull (stuffing box) is lubricated byengine water pressure and the engines areinterconnected, care must be taken thatwater from the running engine does notenter the exhaust of the non-running engine(s). This water could cause seizure of thenon-running engine(s). See your authorizedYanmar Marine dealer or distributor for acomplete explanation of this condition.If you have an installation with two or threeengines, and only one engine is operating,it is important to limit the amount of throttleapplied to the running engine. If you observeblack smoke or movement of the throttledoes not increase engine rpm, you areoverloading the engine that is running.Immediately throttle back to approximatelytwo-thirds throttle or to a setting where theengine performs normally. Failure to do somay cause the running engine to overheator cause excess carbon buildup which mayshorten the engine's life.YM Series Operation Manual 2007 Yanmar Marine International7

be directed to various components of the thermal system. The coolant-based heat distribution is adaptable and saves signifi - cant amounts of refrigerant per vehicle. Also, a coolant-based system reduces refrigerant emissions by requiring fewer refrig - erant pipe joints. The authors present bench-level test data and simulation analysis and describe a preliminary control scheme for this system .
