Bleeding Fuel System If the generator set engine runs out of fuel, if air leaks develop in the suction side of the fuel system, or when replacing the fuel filter, bleed the entire system to prevent starting failures and/or erratic operation. NOTE Connect the battery during the priming procedure to allow engine cranking.
Air Intake Silencer/Cleaner A round polyurethane sound-absorbing type intake silencer silences the intake air drawn into the cylinder head from the intake port. Besides providing a silencing effect, the silencer also acts as an air cleaner. Clean the air silencer as listed in the service schedule. Clean more frequently if operating in dirty, dusty conditions.
(blower wheel) for buildup of carbon residue. If the compressor requires cleaning, contact authorized Kohler service distributor/dealer, who should use a Yanmar approved turbocharger cleaner. 4. Place air intake silencer over turbocharger compressor housing inlet and tighten clamp. Direct the air intake silencer duct down and away from the engine.
Governor The centrifugal, mechanical governor keeps engine speed constant by automatically adjusting the amount of fuel supplied to the engine according to changes in the load. The governor requires no regular service. The governor is adjusted during run-in at the factory. Further adjustments are unnecessary except under greatly varying load conditions or if poor governor control develops after extended usage.
Cooling Systems Closed/Heat Exchanger WARNING In a closed cooling system, the seawater does not circulate through the engine. Rather, the seawater circulates through the separate chambers within the manifold to cool the engine water. The seawater then mixes with engine exhaust and ejects out the exhaust Hot coolant and steam.

If the seacock or permanent structure at a point not higher pipe is too long, water draw problems may occur. To than seawater pump. Ensure that the strainer is remedy some problems with long pipe runs (usually accessible for servicing.
Closed/Heat Exchanger Closed heat exchanger cooling is the best alternative for most applications. Kohler Co. recommends using closed heat exchanger cooling if the craft is operated in saltwater or water with high silt content. Provide service accessibility for the water-cooled exhaust manifold pressure cap.
Exhaust Systems General WARNING Use water-cooled exhaust lines in all marine installations. Keep the lines as short and straight as possible. ABYC Safety Standards P-1.6.i. recommends using two corrosion-resistant hose clamps, with a minimum width of 1/2 in. (13 mm), on each end of flexible Carbon monoxide.
