Maintenance Instructions
3. Remove the dipstick, oil fill cap, and open oil
drain valve, and drain the oil into a suitable con­
tainer. Be sure to allow ample time for complete
drainage.

4. Before removing the oil filter, clean the area
around the filter to keep dirt and debris out of
the engine.
5. Remove the old oil filter and wipe off the filter
mounting surface on the engine.
6. Apply a thin coating of clean oil to the rubber
gas ket on the replacement oil filter.
IMPORTANT: Use ONLY oil filters from the en­
gine manufacturer (Kohler P/N 12­050­01). Af­
termarket oil filters may not 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 the
filter clockwise until the rubber gasket con tacts
the sealing surface, then tighten an additional
3/4 turn to 1 turn.
8. Close the oil drain valve and tighten until snug.
Do not overtighten.
9. Fill the crankcase 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 assure
proper lubrication in hot weather. Fill up to, but
not above, the "F" mark on the dipstick.
Crankcase capacity is 2.0 quarts (1.9 liters)
when changing oil and filter.
IMPORTANT: Check the dipstick reading be­
fore adding the last 1/2 pint of oil and fill only to
the "F" mark. The oil level should never be
above the "F" mark on the dipstick; overfilling can
result in engine overheating, loss of power, and
possible engine damage.
10. Start the engine and check for oil leaks around
the oil filter. Stop the engine, recheck the oil
level, and add oil if necessary. (When the en­
gine is first operated with a new oil filter, the oil
level will drop slightly as the filter is filled with
oil.)
