Using Blended Fuels

If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:

• 

Always use fresh unleaded gasoline 

• 

Use the fuel additive STA-BIL® or an equivalent

• 

Drain tank and run the engine dry before storing unit

Using Fuel Additives

The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and 
minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful 
deposits in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel 
according to the instructions on the fuel additive container. NEVER add fuel additives directly to the 
unit’s gas tank. 

FUELING THE UNIT

1.  Remove the fuel cap (Fig. 7).

2.  Place the gas container’s spout into the fi ll hole on the fuel 

tank and fi ll.

NOTE: 

Do not overfi ll the tank. 

3.  Wipe up any gasoline that may have spilled.
4.  Reinstall the fuel cap.
5.  Move the unit at least 30 ft. (9.1 m) from the fueling source and 

site before starting the engine. 

NOTE: 

Dispose of any old gasoline in accordance with federal, 
state and local regulations.

 RECOMMENDED OIL TYPE

Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before 
each use and change the oil regularly. Failure to use the correct oil, or using dirty oil, can cause 
premature engine wear and failure.
Use a high-quality SAE 30 weight oil of API (American Petroleum 
Institute) service class SF, SG, SH.

ADDING OIL TO CRANKCASE: INITIAL USE
NOTE:
 

This unit is shipped without oil in the engine. To avoid 
damage to the unit, put oil in the crankcase prior to 
starting the unit.

This unit is supplied with one 2.03 fl .oz.
(60 ml) bottle of SAE 30 SF, SG, SH oil (Fig. 4).
NOTE: 

Save the empty oil bottle. It can be used to measure the 
correct amount during future oil changes. See Changing 
the Oil
.

1.  Unscrew the top of the bottle of oil and remove the paper seal 

covering the opening. Replace the top and cut the tip off the 
funnel spout (Fig. 4).

2.  With the unit on a fl at level surface, remove the oil plug (Fig. 5). 
3.  Pour the entire bottle of oil into the oil fi ll hole (Fig. 6).
NOTE: 

Never add oil to the fuel or fuel tank.

4.  Wipe up any oil that may have spilled and reinstall the oil fi ll 

plug.

Check oil before each use and change as needed. Refer to 
Checking the Oil Level.

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for poor unit performance. Be sure 
to use fresh, clean, unleaded gasoline.
NOTE: 

This is a four cycle engine. In order to avoid damage to 
the unit, do not mix oil with gasoline.

Defi nition of Blended Fuels
Today’s fuels are often a blend of gasoline and oxygenates such as 
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel 
can form acids when stored. Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.

OIL AND FUEL INFORMATION

WARNING: OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL 
INJURY. Check and maintain the proper oil level in the crankcase; it is important and 
cannot be overemphasized. Check the oil before each use and change it as needed. See 
Changing the Oil.

WARNING: DO NOT USE E85 FUEL IN THIS UNIT. 

It has been proven that fuel containing greater than 10% ethanol will likely damage this 
engine and void the warranty.

WARNING: Gasoline is extremely fl ammable. Ignited vapors may explode. Always stop 
the engine and allow it to cool before fi lling the fuel tank. Do not smoke while fi lling the 
tank. Keep sparks and open fl ames at a distance from the area.

WARNING:  Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit 
without the fuel cap securely in place.

WARNING: Add fuel in a clean, level and well ventilated outdoor area. Wipe up any 
spilled fuel immediately. Avoid creating a source of ignition for spilled fuel. Do not start the 
engine until fuel vapors dissipate.
