OPERATION
3. Reinsert the dipstick into the locked position before starting the
engine.
NOTE:
Do not overfill. Overfilling with oil may cause smoking, hard
starting, spark plug fouling, or oil saturation of air cleaner.
Fuel Requirements
Use automotive gasoline (unleaded or low leaded to minimize combus-
tion chamber deposits) with a minimum of 87 octane. Gasoline with
up to 10% ethanol or 15% MTBE (Methyl Tertiary Butyl Ether) can be
used. Never use an oil/gasoline mixture or dirty gasoline. Avoid getting
dirt, dust, or water in the fuel tank.
DO NOT use E15 or E85
gasoline.
•
Refuel in a well-ventilated area with the engine stopped. Do not
smoke or allow flames or sparks in the area where the engine is
refueled or where gasoline is stored.
•
Do not overfill the fuel tank. After refueling, make sure the tank
cap is closed properly and securely.
•
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor
may ignite. If any fuel is spilled, make sure the area is dry before
starting the engine.
•
Avoid repeated or prolonged contact with skin or breathing of
vapor.
Fuel Cap
Remove the fuel cap to add fuel.
GAS AND OIL FILL-UP
NOTE:
The engine is shipped without gasoline or oil in the engine.
Running the engine with insufficient oil can cause serious engine
damage and void the engine warranty.
Oil Recommendations
Before starting engine, fill with motor oil, capacity is 600 ml/20 oz.
Refer to viscosity chart in Fig. 3-1 for oil recommendations. Do not
over-fill. Use a 4-stroke, or an equivalent high detergent, premium qual-
ity motor oil certified to meet or exceed U.S. automobile manufacturer’s
requirements for service classification of a minimum level SJ (higher
letter ratings are acceptable such as SL and SM grades).
SAE 10W-30 is recommended for general, all temperature use. If
single viscosity oil is used, select the appropriate viscosity for the
average temperature in your area from the chart below.
1. Single Viscosity
2. Multi Viscosity
CAUTION:
Do not use non-detergent oil or 2-stroke engine oil. It could
shorten the engine’s service life.
NOTE:
A 5w30 synthetic oil may be used to improve start ability for
cold weather (temperatures below 400 F).
Checking Oil Level
IMPORTANT:
Be sure to check the oil while on a level surface with the
engine stopped.
1. Remove the oil filler cap and wipe the dipstick clean. See Figure
9. Insert the dipstick into the oil filler neck. Turn the dipstick a 1/4
turn into the locked position to fully seat.
2. Remove dipstick. If the level is low, slowly add oil to the upper
limit on the dipstick. See Figure 9 inset.

CAUTION
Operating the engine with E15 or E85 fuel, an oil/gasoline mixture,
dirty gasoline, or
gasoline over 30 days old
without fuel stabilizing
additive may result in damage to your engine’s carburetor. Sub-
sequent damage would
not
be covered under the manufacturer’s
warranty.
