NOTE: Multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, and
you should check your engine oil level fre-
quently to avoid possible engine damage
from running low on oil.
Change the oil after every 25 hours of
operation 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
starting the engine and after each fi ve (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to drain
oil, empty 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 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.
Rock lawn mower back and forth to re-
move any oil trapped inside of engine.
4. Wipe off any spilled oil from lawn
mower or side of engine.
5. Fill engine with oil. The engine oil
capacity is 18.5 oz. If oil is not com-
plete ly drained from engine, you may
not need the entire container of a 20
oz. bottle of oil. Slowly pour 3/4 of the
oil from the container down the oil fi ll
spout into the engine.
6. Wait one minute to allow oil to settle.
Use guage on oil fi ll cap/dipstick for
checking level. Insert dipstick into the
tube and rest the oil fi ll cap on the tube.
DO NOT thread the cap into the tube
when taking reading.
7. Continue adding small amounts of
oil and rechecking the dipstick until it
reads full. DO NOT overfi ll, or engine
will smoke on startup.
8. Always be sure to retighten oil dipstick
before starting engine.
