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

4. Before removing the oil lter, clean the area
around the lter to keep dirt and debris out of
the engine.
5. Remove the old oil lter and wipe off the lter
mounting surface on the engine.
6. Apply a thin coating of clean oil to the rubber
gasket on the replacement oil lter.
IMPORTANT: Use ONLY oil lters from the en-
gine manufacturer (Kohler 12-050-01). After-
market oil lters may not seal properly and/or
may not have the correct pressure relief valve
for proper lubrication.
7. Install the new oil lter on the engine. Turn the
lter clockwise until the rubber gasket contacts
the sealing surface, then tighten an additional
1/2 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
Specications 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 dip-
stick. Crankcase capacity is 1.85 quarts (1.75
liters) plus 1/2 pint (0.24 liters) for the new oil
lter.
IMPORTANT: Check the dipstick reading be-
fore adding the last 1/2 pint of oil and ll only to
the “F” mark. DO NOT overll the crankcase
(oil above “F” mark) as this CAN result in en-
gine overheating, loss of power, and possible
engine damage.
10. Start the engine and check for oil leaks around
the oil lter. Stop the engine, recheck the oil
level, and add oil if necessary. (When the en-
gine is rst operated with a new oil lter, the oil
level drops slightly as the lter is lled with oil.)
