F_g. 2 OraLAND FUEL MmXH_G H_STRUCTmONS Old and/or improperly raked fuel are the main reasons for the unit not running properly. Be sure to use fresh (less than 60 days old), 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 gaso%e 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 and leads to formation of adds during storage. When using alcohol-blended fuel, use fresh fuel. To Obtain Correct Fuel Mix: 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 Fuel Mixture Table 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. FUEL MIXTURE Using Blended Fuels if you choose to use a blended fuel or its use is unavoidable, follow recommended precautions: TABLE + • AHways use the fresh rue[ mix explained in your operator's manual • Always shake the fuel mix before fueling the unit • Drain the tank and run the engine dry before storing the unit UNLEADED GAS 1 GALLON US (&8 LITERS) 2 CYCLE OIL 32 FL OZ. msram) 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 always use Craftsman 2-cycle oil with this unit. if Craftsman 2-cycle oil is unavailable, use a good 2cycle oil designed for air-cooled engines along with a fuel additive, such as STA-B[L" 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 tanL , For proper engine • operation and maximum re[lability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed rue[ can severeJy damage the engine. 25 mm 1 LITER MIXING RATIO - 40:1 WARNING: Gasoline is extremely flammable. Ignited vapors may explode. Always stop the engine and allow it to cool the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area. WARNING: Remove fue, cap slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in place. WARNING: Add fue, in a c,ean, 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, NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations. WARNING: Operate this unit onIy in a weII-ventiIated outdoor area. Carbon monoxide exhaust fumes can be lethal in a confined area. _ Stop/Off Start/On, (O) WARNING; Avoid acddental starting, Make sure you are in the starting position when pulling the starter rope (Fig. 5). To avoid serious injury, the operator and unit must be in a stable position while starting. Throttle Control F_g.3 STARTING 1. iNSTRUCTiONS Mix gas with oil. Fill fuel tank with fuel/oil mixture.

Push the red EZ-Fire TM Lever towards the primer bulb until it clicks and locks into place (Fig. 4). NOTE: The unit uses the Jncredi-Pull TM starting system with MAX FiRE iGNiTiON TM , which significandy reduces the effort required to start the engine. You must pull the starter rope out far enough to hear the engine attempt to start. There is no need to pull the rope briskly-- there is no harsh resistance when pulling. Be aware that this starting method is vastly different from (and much easier than) what you may be used to. Red EZ:Fire Lever Fig. 4 Starting with a controlled and steady motion up to 10 times, until the engine starts. 6. When the engine starts, squeeze the throttle control for 15 to 30 seconds. This will warm up the unit. The red EZ-Fire TM lever will click off automatically when you squeeze the throttle control. \lnered,-Pu,!

TraPS FOR BEST TRmMMmNG RESULTS • Keep the cutting attachment paraHeHto the ground. • Do not force the cutting attachment. AHow the tip of the Hineto do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine. • Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag. • Cut from left to right whenever possible, Cutting to the right improves the unit's cutting efficiency, Clippings are thrown away from the operator, • Slowly move the trimmer in and out of the cutting area at the desired height. Move either in a forwardbackward or side-to-side motion. Cutting shorter lengths produces the best results. • Trim only when grass and weeds are dry, • The life of your cutting line is dependent upon: • Following the trimming techniques • What vegetation is being cut • Where vegetation is cut Fig. 10 USING THE TWIST AND EDGE TM FEATURE You can use the Twist and unit to edge grass: 1, Edge TM coupler to convert the Make sure the unit is turned completely off, 2, Turn the knob counterclockwise 3, to loosen, Grasp the boom below the coupler and firmly twist it 90 " in either direction (depending on which way you want to edge). 4, Turn the knob clockwise to tighten (Fig. 11), Coupler Boom For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree, Knob Fig. 11 11 MAINTENANCE SCHEDULE NOTE: Maintenance, repHacement, or repair of the emission controH devices and system may be Perform these required maintenance procedures at the frequency stated in the tame.
