Gas&OU
NOTE:The engine is shipped without gasoline in the engine.
Running the engine with insufficient oil can cause serious engine
damage and void the engine warranty.
iMPORTANT:
Some engines are shipped with oil already in
the engine, others without oil already in the engine. It is very
important to check the oil level before operating the engine and
to add oil if necessary. Running the engine with insufficient oil
can cause serious engine damage and void the engine warranty
Before starting engine, fill with motor oil, capacity is 600 ml/20
oz. Refer to the viscosity chart (Fig. 3-1) for oil recommendations.
Do not over-fill. Use a 4-stroke, or an equivalent high detergent,
premium quality motor oil certified to meet or exceed
U.S. automobile manufacturer's requirements for service
classification of a minimum level SF or SG (higher letter ratings
are acceptable such as SJ, SL and SM grades). Motor oil will
display this designation on the container.

NOTE: Do not use non-detergent oil or 2-stroke engine oil. It
could shorten the engine's service life.
Checkingthe Oil
Since this manual covers several different engine models,
instructions for checking the oil with various different oil cap/
dipstick configurations follow. Refer to the instructions that
pertain to the particular engine model that you have. The three
different configurations that exist are oil cap/dipsticks that appear
on the engine block, and two models with raised engine fill/oil
cap configurations. One of the raised cap units has a quarter-turn
oil fill/dipstick and the other a threaded oil fill/dipstick. Only
on the quarter-turn model do you tighten the cap to check the
oil level. The other two models you just rest the dipstick on the
threads to check. See the instructions that follow for more detailed
information regarding the particular engine model thatyou have.
CheckingOil LevelOn Engineswith Dipstick on EngineBlock
NOTE: Be sure to check the oil while on a level surface with the
engine stopped.
To avoid engine damage, it is important to:
Check oil level before each use and every 5 operating
hours when engine is warm. Check oil level more
frequently during engine break-in.
Keep oil level near or slightly below the upper level
mark on the dipstick or to point of overflow on
engines without dipstick. See Fig. 3-2.
Be sure oil fill cap/plug is tightened securely.
I. Remove the oil filler cap/dipstick and wipe the dipstick
clean. See Fig. 3-2.
2. Insert the cap/dipstick into the oil filler neck, but do not
screw it in.
3.
f
Remove the oil filler cap/dipstick. If the level is low, slowly
add oil until oil level registers between high (H) and low (L),
Fig. 3-2.
Figure 3-2
4. Replace and tighten cap/dipstick firmly before starting
engine.
NOTE: Do not overfill. Overfilling with oil may cause smoking,
hard starting, or spark plug fouling.
NOTE: DO NOT allow oil level to fall below the "L" mark on the
dipstick. Doing so may result in equipment malfunctions or
damage.
NOTE: some engines are equipped with a dipstick or oil fill plug.
NOTE:To change the oil on your engine, see the Maintenance
Section of this manual.
