Changing Engine Crankcase Oil and Filter

Change the engine crankcase oil after every 100
hours of operation and replace the oil filter every
other oil change (every 200 hours of operation).
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 opera-
tion, start the engine and run a few minutes to
warm the oil.
2. Before removing the dipstick, clean the area
around it to keep any dirt or debris out of the
en gine.
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 drain-
age.

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
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.
7. Install the new oil filter on the engine. Turn the
filter clockwise until the rubber gasket contacts
the sealing surface, then tighten an additional
3/4 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 Crankcase
Lubricant on page 3 in the Specifications
section of 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) plus 1/2 pint (0.24
liters) for the new oil filter.
