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 fresh fuel mix per 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 use of fuel additive, 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 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 32:1 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 4 oz. (120 ml.) bottle of RYOBI 2 CYCLE OIL makes a 32:1 fuel/oil ratio.

UNLEADED GAS RYOBI 2 CYCLE OIL
1 US. GALLON + 4.0 FL. OZ. (3.8 LITERS) (120 ml) 1 LITER + 30 ml MIXING RATIO - 32:1
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 area outdoors. Wipe up any spilled fuel immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.
NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State, and Local regulations.
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.
STARTING/STOPPING INSTRUCTIONS

CARBURETOR SETTING

The idle speed adjuster of the engine is adjustable though the Air filter/muffler cover (Fig 27). NOTE: Careless adjustments can seriously damage your unit. An authorized service dealer should make carburetor adjustments. Check Fuel Mixture Old and/or improperly mixed fuel is usually the reason for the unit not running properly. Drain and refill the tank with fresh, properly mixed fuel prior to making any adjustments. Refer to Oil and Fuel Information. Clean Air Filter The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow and change the air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed adjuster. Refer to Air Filter Maintenance. Adjust Idle Speed Adjuster WARNING: This unit will need to be running during idle speed adjustment. Wear protective clothing and observe all safety instructions to prevent serious personal injury. Also, DO NOT set unit on any surface except a clean, hard area while starting or performing any adjustments. Debris such as gravel, sand, dust, grass, etc. could be picked up by the air intake and thrown out by the discharge opening, damaging unit, property, or causing serious injury to bystanders or operator. If after checking the fuel mixture and cleaning the air filter the engine still will not idle, adjust the idle speed adjuster as follows. 1. Start the engine and let it run at a high idle for a minute to warm up. 2. Set the blower/vacuum mode change-over lever to the up position (Blower Mode). See Operating as a Blower. NOTE: Setting the lever to the blower mode prevents the vacuum bag from filling up while starting or running the unit. 3. Move the throttle control and let the engine idle. If the engine stops, insert a small phillips or flat blade screwdriver into the hole in the air filter/muffler cover (Fig. 27). Turn the idle speed adjuster in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly. 4. If the unit appears to be idling too fast, turn the idle speed adjuster counterclockwise 1/8 of a turn at a time (as needed), to reduce idle speed.
