modelSaildrive Your Safety1 For Your Safety11 Safety Precautions For smoke or permit sparks near the battery because it may emit explosive hydrogen gas Place the battery in a wellventilated placeFuelUse only diesel fuel Never use other fuels including gasoline kerosene etc because they could cause a fire The wrong fuel could also cause the fuel injection pump and injector to fail due to lack of proper lubrication Be sure to check that you have selected the correct diesel fuel before filling the fuel tankDo not use starting fluids or sprays Their use may cause explosion serious injury and engine damageFire PreventionBe sure to stop the engine and confirm that there are no open flames in the vicinity before fueling If you do spill fuel wipe such spillage carefully and dispose of the wiping materials properly Wash your hands thoroughly with soap and waterNever place oil or other flammable material in the engine roomInstall a fire extinguisher near the engine room and familiarize yourself with its useExhaust GasExhaust gas contains poisonous carbon monoxide and should not be inhaledBe sure to install ventilation ports or ventilators in the engine room and ensure good ventilation during engine PartsDo not touch or let your clothing get caught in the moving parts of the engine such as the front drive shaft Vbelt or propeller shaft during engine operation You will be injuredNever operate the engine without covers on the moving Your SafetyThe whole engine is hot during operation and immediately after shutdown The exhaust manifold exhaust pipe and high pressure fuel lines are very hot Never touch these parts with your body or clothingNever operate the engine while you are under the influence of alcoholNever operate the engine when you are ill or not feeling wellBattery FluidBattery fluid is dilute sulphuric acid It can blind you if it gets in your eyes or burn your skin Keep the fluid away from your bodyIf you touch it wash it off immediately with a large quantity of fresh water and call your doctor for treatmentFire by Electric turn off the battery switch before inspecting the electrical systemFailure to do so could cause and firesStop the engine before you service itTurn the battery switch off If you must inspect while the engine is in operation never touch moving parts Keep your body and clothing well clear of all moving partsWhen extracting oil from the engine while it is still hot dont let the oil splash on youWait until the temperature has dropped before extracting cooling water from the engine Dont let it splash on youRR1For Your release the limiting devices such as the engine speed limit fuel injection limit will impair the safety athe product and shorten product lifeAlso note that any troubles arising from

SailDrive for the First TimeNote The propeller shaft output becomes 95 of the engine rated output continuous rating at crankshaft in consideration of mechanical efficiency 95 of the saildrive3In the case of propeller calculation further add 5 at minimum as the sea margin to the aforementioned matching point That is 95 of the propeller shaft rated output Continuous rating at propeller shaft becomes the best propeller matching Note about sea margin In actual navigation there is an increase in resistance due to the waves wind and fouling of the hull and moreover a drop in the efficiency due to fouling of the propeller Consequently in the case of propeller calculation it is necessary to allow the engine output to have some margin For that reason it is necessary to add the sea margin of 5 at of Operation51 Engine Cooling Water Opening or closing the cooling water system of the SailDrive Set Engine is done by the cooling water cock fixed on the upper case of the SailDrive Be sure to open the cock and confirm that the CW has suction by cranking the engine before starting the boat The cooling water passes through the SailDrive case cools the engine by the cooling water pump and is then discharged Note For other items refer to the engine operation manualNote When sailing set the remote control lever in neutral Old type Serial No00012128 for Model SD20 Serial No2129 and after
