Changing Engine Crankcase Oil/Oil Filter
Change the engine crankcase oil and filter
every
300 hours
if the recommended Kohler PRO
®
prod-
ucts are being used. If conventional oil and filters
are being used, change the crankcase oil
after
every 100 hours
of operation and replace the oil
filter
after 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 the dipstick to keep any dirt or debris
out of the en gine.
3. 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.

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
Kohler oil filters.
See the
Specifications
section for a list of
recommended filters. After market oil filters
may not seal properly and/or may not have the
correct pressure relief valve for proper lubrica-
tion.
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
1/2 to 3/4 turn.
8. Reinstall the oil drain plug. Make sure it is
tightened to 10 lb·ft (14 N·m).
9. Remove the fill cap on the engine valve cover,
and fill the crankcase with new, clean oil. Use
only crankcase lubricants recommended by
the en gine manufacturer. Refer to
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.
