OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS
CAUTION:
For proper engine operation and maximum reliability, pay strict attention to the oil and fuel
mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.
Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean
unleaded fuel. Follow the instructions carefully for the proper gasoline/oil mixture, or use TruFuel® 40:1 Premixed Gas
& Oil (PN 6525538).
Definition 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 make fuel and oil separate. It forms acids when
stored. When using alcohol-blended fuel, use fresh fuel (less than 30 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in your operator's manual
• Use the fuel additive STA-BIL® or an equivalent
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and minimize
the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit. If unavailable, use a good
2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL® Gas Stabilizer or an
equivalent. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel according to the instructions on the container. NEVER
add fuel additives directly to the unit's fuel tank.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a 40:1 fuel/oil
ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and oil mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one 3.2 oz. (95 ml) bottle of 2-cycle oil makes a 40:1
fuel/oil ratio.
NOTE: Dispose of the old fuel/oil mix in accordance with federal, state and local regulations.
*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 flammable. Ignited vapors may
explode. Always stop the engine and allow it to cool before filling the
fuel tank. Do not smoke while filling the tank. Keep sparks and open
flames 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, 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.

STARTING INSTRUCTIONS
NOTE: When starting the unit, make sure it is not directed at bystanders or loose debris.
1. Mix gas with oil. Fill the fuel tank with fresh fuel/oil mixture. See Oil and Fuel
Mixing Instructions.
NOTE: There is no need to turn the unit on. The On/Off switch is in the ON ( I )
position at all times (Fig. 10).
2. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel
should be visible in the primer bulb (Fig. 11). If fuel cannot be seen in the bulb,
press and release the bulb until fuel is visible.
3. Move the choke lever to Position 1 (Fig. 11).
NOTE: The unit should be started in idle. Do not squeeze the trigger until step 8 (Fig. 10).
4. Do not squeeze the trigger. Place the unit on a firm, flat surface. Crouch in the
starting position and hold the unit firmly (Fig. 12).
5. Do not squeeze the trigger. Pull the starter rope out until some resistance is felt.
This is usually around 2–4 inches. Pull the starter rope 5 times in a controlled and
steady motion.
6. Do not squeeze the trigger. Move the choke lever to Position 2 (Fig. 11).
7. Do not squeeze the trigger. Pull the starter rope 3-5 times in a controlled and
steady motion to start the engine.
8. Squeeze and hold the trigger, or press down the cruise control (Fig. 10), and allow
the engine to warm up for 30 to 60 seconds.
9. Continue to squeeze the trigger. Move the choke lever to Position 3 (Fig. 11).
10. Continue to squeeze the trigger. Continue warming the engine for an additional
60 seconds. The unit is now ready for use.

IF... the engine does not start, begin the starting procedure with step 2.
IF... The engine fails to start after 2 attempts, move the choke lever to Position 3,
squeeze the trigger, and pull the starter rope 3-8 times in a controlled and steady
motion. The engine should start. If not, repeat.
UNLEADED GAS* 2-CYCLE OIL
IF... the engine is already warm, begin the starting procedure with step 6.
