Changing Engine Crankcase Oil/Oil Filter
Change the engine crankcase oil
after every 50
hours
of operation and the oil filter
after every
100
hours
of operation as follows:
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 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 new oil to the rubber gas-
ket on the replacement oil filter.
IMPORTANT:
Use
ONLY
oil filters from the
en gine manufacturer (Briggs & Stratton
P/N 492932). After market oil filters may not seal
properly and/or may not have the correct pres-
sure 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
1/2 to 3/4 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 as-
sure proper lubrication in hot weather.
Fill to
FULL mark
on the dipstick; crankcase capacity
is 1.5 quarts (1.4 liters) when changing oil and
filter.
