Set-Up

Gas & Oil
:
NOTE The engine is shipped without gasoline
and with motor oil in the engine. However, you
MUST check the oil level before operating. Be
careful not to overfill. Running the engine with
insufficient oil can cause serious engine damage
and void the engine warranty.
WARNING!
Always keep hands and feet clear of equipment
moving parts. Do not use a pressurized starting
fluid. Vapors are flammable.

Oil Recommendations

Before starting engine, check oil level, capacity
is 1900 ml/64.25 fl. oz. Refer to viscosity chart
in Figure 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 SJ (higher
letter ratings are acceptable such as SL and SM
grades). Motor oil will display this designation
on the container.
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.

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
NOTE: Be sure to check the oil while on a level
surface with the engine stopped.
1. Remove the oil filler cap/dipstick and
wipe the dipstick clean.
2. Insert the dipstick into the oil filler neck.
Turn the dipstick a 1/4 turn into the
locked position to fully seat. See Figure
3-2.
Upper
Level
3. Remove dipstick to check the oil level.
4. If the level is low, slowly add oil to the
upper limit on the dipstick. See Figure
3-2 inset.
5. Reinsert the dipstick and turn to the
locked position before starting the
engine.
NOTE: Do not overfill. Overfilling with
oil may cause smoking, hard starting,
spark plug fouling, hydraulic lock, or oil
saturation of air cleaner.

Fuel Requirements

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
30
carburetor. Subsequent damage would not be
covered under the manufacturer's warranty.
Use automotive gasoline (unleaded or low
leaded to minimize combustion chamber
deposits) with a minimum of 87 octane.
Gasoline with up to 10% ethanol (E10) or 15%
MTBE (Methyl Tertiary Butyl Ether) can be used.

Never use an oil/gasoline mixture or dirty
70º 85º 105º
gasoline. Avoid getting dirt, dust, or water in the
fuel tank. DO NOT use E15 or E85 gasoline.
Gasoline is extremely flammable and is
WARNING!
explosive under certain conditions.
• 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.
Figure 3-2
CAUTION
WARNING!
• 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.

Adding Fuel

WARNING!
An adult should fuel this engine. NEVER
WARNING!
allow children to refuel the engine. Gasoline (fuel)
vapors are highly flammable and can explode.
Fuel vapors can spread and be ignited by a spark
or flame many feet away from engine. To prevent
injury or death from fuel fires, follow these
instructions:
• DO NOT use leaded fuel.
• Fuel must be fresh and clean. NEVER use
fuel left over from last season or stored for
long periods.
• NEVER mix oil with fuel in this engine.
• DO NOT use fuel containing Methanol
(Wood Alcohol).
NOTE: Before refueling, allow engine to cool
two minutes.
1. Clean around fuel fill before removing
cap to fuel.
2. Fill tank until fuel reaches 1⁄2 inch below
the bottom of the filler neck to allow
space for fuel expansion. Be careful not
to overfill.
3. Replace the fuel cap and tighten securely.
Wipe up spilled fuel before starting
engine. If fuel is spilled DO NOT start
engine. Move machine away from area
of spillage. Avoid creating any source of
ignition until fuel vapors are gone.
NOTE: For more information regarding fuel,
refer to Operator's Manual shipped with
machine.
