Maintenance Instructions KAWASAKI TIPS41IMPORTANT TIPS FOR CARE OF THEKAWASAKI ENGINEFuel System• Fuel must be clean - free from water, dirt, and or-ganic material.• Clean the fuel filter on a regular basis and whencontamination is suspected or found in the fuel.Starting• Start engine with the throttle advanced off idle(1/4 to 1/2 throttle). This will aid starting, especiallyin cold weather.• Keep the battery fully charged.• Match crankcase oil viscosity to the ambient tem-perature, allowing the engine to crank faster andstart easier.• Allow engine to run at idle for a few seconds be-fore stopping engine to avoid run-on or backfiring.Cooling System• Keep engine air intake screen and cylinder headfins free of grass clippings, chaff, and dirt. Inspectintake screen and cooling fins for cleanliness anddamage.• Check performance of the cooling system bystarting the engine, holding a hand adjacent to thecylinder head, and feeling the cooling airflow.• Operate the engine at full speed when mowing.This will allow the engine to produce full horsepowerand move more cooling air through the engine cool-ing fins.Air Cleaner• Use only Donaldson air cleaner elements. After-market elements may not seal in the air cleanerhousing, allowing dirt to enter the engine. Also, af-termarket filters often skimp on the filtration mediaand require more frequent cleaning and replace-ment (see instructions below).• Use the air flow restriction gauge to indicate theneed to service the air filter.• DO NOT overservice or frequently “disturb” theair filter. A dirty air filter actually cleans better thana new one. Changing and cleaning the filter too of-ten can actually reduce filter efficiency and increasethe opportunity for traces of dust to enter the engine.Wait until the element really needs servicing as indi-cated by the loss of engine power.• When the air filter element is removed or re-placed, make sure all dust is cleaned out of the aircleaner housing and hose. Use a damp cloth andwipe the interior of the canister and hose clean (alittle dirt left here will be sucked into the engine andreduce engine life). When the filter is reinstalled,make sure the element is held tight and straightin the canister for proper seating and sealing.• Periodically check the air intake hose for cuts,nicks, etc., and the hose clamps for tightness.Oil• DO NOT screw filler cap into crankcase whenchecking oil level.• Single viscosity or multi-viscosity oils may beused with the viscosity matching ambient tempera-tures for the engine operating conditions. This willaid starting in cold weather and assure proper lu-brication in hot weather.• Use only Kawasaki oil filters. Aftermarket filtersmay not seal properly and/or have the incorrectpressure relief valve for proper lubrication.DANGERMake sure to keep hands clear of exhaustpipe, muffler, and moving parts whenchecking airflow.
