GENERAL INFORMATIONCORRECT LUBRICATION IS IMPORTANTAny high quality detergent oil having the American Petroleum Institute classification “For Service SC, SD, SE or MS” canbe used in Briggs & Stratton engines. Detergent oils keep the engine cleaner and retard the formation of gum and varnishdeposits.SUMMERWINTER(Above 40° F.)(Under 40° F.)Use SAE 30Use SAE 5W-20 or SAE 5W-30If not available,If not available,Use SAE 10W or SAE 10W-30Use SAE 10W-30Below 0° F,orUse SAE 10W or SAE 10W-30SAE 10W-40Diluted 10% with KeroseneThe oil recommendations are the result of extensive testing. No special additives should be used.OIL SHOULD BE CHANGED AFTER EACH 25 HOURS OF ENGINE OPERATION. (More often under dirty operatingconditions). In normal running of any engine, small particles of metal from the cylinder walls, pistons and bearings willgradually work into the oil. Dust particles from the air also get into the oil. If the oil is not changed regularly, these foreignparticles cause increased friction and a grinding action which shorten the life of the engine. Fresh oil also assists incooling, for old oil gradually becomes thick and loses its cooling effect as well as its lubricating qualities.The air cleaner should be serviced every 25 hours of engine operation. Dirty operating conditions re-quire more frequentservicing.CLEAN COOLING SYSTEMGrass particles, chaff or dirt may clog the air cooling system, expecially after prolonged service in cutting dry grasses.Continued operation with a clogged cooling system may cause severe overheating and possible engine damage. Thefigures below show the blower housing removed and area to be cleaned. This should be a regular maintenanceOperation.1
