Apply a thin coating of new oil to the rubber gas-ket on the replacement oil filter.IMPORTANT: Use ONLY oil filters from theengine manufacturer. Aftermarket oil filters maynot seal properly and/or may not have the cor-rect pressure relief valve for proper lubrication.7. Install the new oil filter on the engine. Turn theoil filter clockwise until the rubber gasket con-tacts the sealing surface, then tighten the filteran additional 1/2 to 3/4 turn.8. Reinstall the drain plug.9. Fill the crankcase with new, clean oil. Use onlycrankcase lubricants recommended by theengine manufacturer. Refer to Specifications inthis manual or the engine owner’s manual. Usethe recommended oil viscosity for the expectedambient temperature. Oil with the correct vis-cosity will aid starting in cold weather and assureproper lubrication in hot weather. Fill to FULLmark on the dipstick; crankcase capacity is 1.5quarts (1.4 liters) when changing oil and filter.IMPORTANT: Check the dipstick reading be-fore pouring in the last 1/2 pint of oil and fill onlyto the FULL mark. The oil level should never beover the FULL mark on the dipstick; overfillingcan result in engine overheating and loss ofpower.10. Start the engine and check for oil leaks aroundthe oil filter. Stop the engine, recheck the oil lev-el, and add oil if necessary. (When the engineis first operated with a new oil filter, the oil levelwill drop slightly as the filter is filled with oil.)Grease Fitting and Oil Point LubricationLubricate the grease fittings and oil points afterevery 25 hours of operation. Lubricate more oftenwhen operating in dusty or dirty conditions. UseSAE general purpose lithium or molybdenum basegrease for grease fittings and light machine oil (SAE10) to lubricate oil points. Lubricate the locationsshown in the Chassis and Deck LubricationPoints illustration.NOTE: PTO universal joints (on the deck and trac-tor) require routine lubrication after every 8 hours ofrunning time.NOTE: The pillowblock bearings on the PTO driveshaft are a sealed, relubricatable-type bearing.Grease lightly once per year using care to notover-lubricate and damage the seals.DipstickOil FillOil DrainOil Filter
