Be sure the guard mounting bracket slides into the slot on the edge of the cutting shield. Rotate the shield into place, counterclockwise. The holes in the guard mounting bracket and cutting attachment shield will line up (Fig. 3). 2. From inside the cutting attachment shield, push the square bolt through the hole until the threaded end protrudes through the guard mounting bracket (Fig. 4).

WARNING: Fig. 2 OIL AND FUEL INFORMATION OIL AND FUEL MIXING INSTRUCTIONS 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 fuel/oil mixture. 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 60 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 • 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. For proper engine CAUTION: 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. 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. + UNLEADED GAS 2 CYCLE OIL 1 GALLON US 3.2 FL. OZ. (3.8 LITERS) (95 ml) 1 LITER 25 ml MIXING RATIO - 40:1 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 spilt fuel. Do not start the engine until fuel vapors dissipate. WARNING: NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations. STARTING/STOPPING INSTRUCTIONS Stop/Off (O) Operate this unit WARNING: only in a well- ventilated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area. Avoid accidental WARNING: starting. Make sure you are in the starting position when pulling the starter rope (Fig. 8). To avoid serious Throttle injury, the operator and unit must be Control in a stable position while starting. Fig. 6 STARTING INSTRUCTIONS 1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel Mixing Instructions. NOTE: There is no need to turn the unit on. The On/Off Stop Control is in the ON ( I ) position at all times. 2. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel should be visible in the primer bulb and fuel lines (Fig. 7). If you can’t see fuel in the bulb, press and release the bulb as many times as it takes before you can see fuel in it. 3. Place the blue choke lever in Position 1 (Fig. 7). 4. Crouch in the starting position (Fig. 8), squeeze the throttle control, and pull the starter rope briskly 5 times. 5. Place the blue choke lever in Position 2 (Fig. 7). 6. While squeezing the throttle control, pull the starter rope briskly until the engine starts. 7. Keep the throttle squeezed and allow the engine to warm up for 15 to ...
