Maintenance Instructions LUBRICATION

1.Park the mower on a level surface with the en- gine stopped. The engine oil should be warm before draining. If not warm from operation, start the engine and run a few minutes to warm the oil.

2.Remove the dipstick and the oil drain plug and drain the oil into a suitable container. Be sure to allow ample time for complete drainage.

3.Before removing the oil filter, clean the area around the filter to keep dirt and debris out of the engine.

4.Remove the old oil filter and wipe off the filter mounting surface on the engine.

5.Apply a thin coating of clean oil to the rubber gasket on the replacement oil filter.

IMPORTANT: Use ONLY oil filters from the en- gine manufacturer (Kohler 12-050-01). After- market oil filters may not seal properly and/or may not have the correct pressure relief valve for proper lubrication

6.Install the new oil filter on the engine. Turn the filter clockwise until the rubber gasket contacts the sealing surface, then tighten an additional 1/2 turn.

7.Reinstall the drain plug. Make sure it is tight- ened to 10 ft-lb (13.6 N·m).

8.Fill the crankcase through the oil filler tube (dip- stick opening) with new, clean oil. Use only crankcase lubricants recommended by the en- gine manufacturer. Refer to Specifications in this manual or the engine owner’s manual. Use the recommended oil viscosity for the expected ambient temperature. Oil with the correct vis- cosity will aid starting in cold weather and as-

sure proper lubrication in hot weather. Fill up to, but not above, the “F” mark on the dipstick. Crankcase capacity is 1.85 quarts (1.75 liters) plus 1/2 pint (.24 liters) for the new oil filter.

IMPORTANT: Check the dipstick reading be- fore adding the last 1/2 pint of oil and fill only to the “F” mark . DO NOT overfill the crankcase (oil above “F” mark) as this CAN result in en- gine overheating, loss of power, and possible engine damage.

9.Start the engine and check for oil leaks around the oil filter. Stop the engine, recheck the oil lev- el, and add oil if necessary. (When the engine is first operated with a new oil filter, the oil level drops slightly as the filter is filled with oil.)

Grease Fitting and Oil Point Lubrication

Lubricate the grease fittings and oil points after ev- ery 25 hours of operation. Lubricate more often when operating in dusty or dirty conditions. Use SAE general purpose lithium or molybdenum base grease for grease fittings and light machine oil (SAE

10)to lubricate oil points. Lubricate the locations shown in the Chassis and Deck Lubrication Points illustration.

NOTE: PTO universal joints (on the deck and trac- tor) require routine lubrication after every 8 hours of running time.
