LUBRICATION
Use only high quality detergent oil rated with
API service classifi cation SF-SJ. Select the
oil's SAE viscosity grade according to your
expected operating temperature.
4. Wipe off any spilled oil from lawn
mower or side of engine.
5. Slowly pour oil down the oil fi ll spout,
stopping every few ounces to check
the oil level with the dipstick.
6. Stop adding oil when you reach the
FULL mark on the dipstick. Wait a
minute to allow oil to settle.
7. Continue adding small amounts of oil,
rechecking the dipstick until oil level
settles at FULL. DO NOT overfi ll, or
engine will smoke heavily from the
muffl er on startup.
8. Always be sure to retighten oil dipstick
before starting engine.
9. Re con nect spark plug wire to spark
plug.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air fi lter. Re-
place the air fi lter every 100 hours of op-
er a tion or every season, which ev er occurs
fi rst. Service air cleaner more often under
dusty conditions. Do not wash air fi lter.

NOTE:
Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi-viscosity oils will
result in increased oil consumption when
used above 32°F. Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of op-
eration or at least once a year if the lawn
mower is not used for 25 hours in one year.
Check the crankcase oil level before start-
ing the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL

: Before tipping lawn mower to drain
oil, drain fuel tank by running engine until
fuel tank is empty.
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
2. Remove engine oil cap; lay aside on a
clean surface.
3. Tip lawn mower on its side as shown
and drain oil into a suitable container.
