Changing Engine Crankcase Oil/Oil Filter
Change the engine crankcase oil after every 100
hours of operation and replace the oil lter after
every 200 hours of operation as follows:
1. Park the mower on a level surface with the
engine 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, and oil ll cap,
clean the area around them to keep any dirt or
debris out of the engine.
3. Remove the dipstick, oil ll cap, and 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 lter, clean the area
around the lter to keep dirt and debris out of
the engine.
5. Remove the old oil lter and wipe o the lter
mounting surface on the engine.
6. Apply a thin coating of clean oil to the rubber
gas ket on the replacement oil lter.
IMPORTANT: Use ONLY oil lters from the
en gine manufacturer (Briggs & Stratton
P/N 842921). After market oil lters may not seal
properly and/or may not have the correct pres
sure relief valve for proper lubrication.
7. Install the new oil lter on the engine. Turn the
lter clockwise until the rubber gasket con tacts
the sealing surface, then tighten an additional
1/2 to 3/4 turn.
8. Reinstall the oil drain plug 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 Specications 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 FULL mark on the dipstick.
Crankcase capacity is 2.4 quarts (2.3 liters)
when changing oil and lter.
IMPORTANT: Check the dipstick reading be
fore adding the last 1/2 pint of oil and ll only to
the FULL mark. The oil level should never be
above the FULL mark on the dipstick; overlling
CAN result in engine overheating, loss of pow
er, 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 will drop slightly as the lter is lled with
oil.)
