CUTTING BLADE + Read and understand all safety warnings before operating this unit. + Always use the shoulder harness when using the brush blade accessory. Keep the J -handle between the operator and cutting attachment or blade at all times. + NEVER cut when the cutting blade is 30 inches (76 cm) or more above the ground level. Blade thrust may occur when the spinning blade contacts an object that it does not immediately cut. Blade thrust can be violent enough to propel the unit and/or operator in any direction, possibly causing a loss of control. Blade thrust can occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut. For operation with the brush blade, do not cut anything thicker than 1/2 inch or a violent kickback could occur.
Do not attempt to touch or stop the blade when it is rotating. A coasting blade can cause injury while it continues to spin after the engine is stopped or the throttle trigger is released. Maintain proper control until the blade has completely stopped rotating. Do not run the unit at high speed when not cutting. If you strike or become entangled with a foreign object, stop the engine immediately and check for damage. Have any damage repaired before attempting further operations. Do not operate unit with a bent, cracked or dull blade. Discard blades that are bent, warped, cracked or broken. Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off while in use. This can result in severe personal injury. Replace the blade. Do not use the cutting blade for edging or as an edger; severe personal injury to yourself or others may incur. Use the cutting blade only for the purpose described in this manual. Stop the engine IMMEDIATELY if you feel excessive vibration. Vibration is a sign of trouble. Inspect thoroughly for loose nuts, bolts or damage before continuing. Repair or replace affected parts as necessary. After Use + Clean cutting blades with a household cleaner to remove any gum buildup. Oil the blade with machine oil to prevent rust. + Lock up and store the cutting blade in an appropriate area to protect the blade from unauthorized use or damage.

Old fuel is the primary reason for improper 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. 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 or form acids when stored. Use fresh fuel (less than 60 days old), when using alcohol-blended fuel. Using Blended Fuels If you choose 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 container. NEVER add fuel additives directly to the unit's gas tank.

AD] USTING TRIMMING LINE LENGTH
The Bump Head" cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 27) while operating the trimmer at high speed. NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter. Each time the head is bumped, about 1 inch (25.4 mm) of trimming line is released. A blade in the cutting attachment shield will cut the line to the proper length if excess line is released. For best results, tap the Bump Head" on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter. NOTE: Do not rest the Bump Head" on the ground while the unit is running. assembly. Excessive line length will make the clutch overheat. This may lead to serious personal injury or damage to the unit. À CAUTION!: ne cut dede” Fig. 27 Some line breakage will occur from: + Entanglement with foreign matter + Normal line fatigue + Attempting to cut thick, stalky weeds + Forcing the line into objects such as walls or fence posts
TIPS FOR BEST TRIMMING RESULTS
+ For best trimming results, operate unit at full throttle. Keep the cutting attachment parallel to the ground. Do not force the cutting attachment. Allow the tip of the line to 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. For the YM26BC brushcutter, cut from left to right whenever possible. Cutting to the right improves the unit's cutting efficiency. Clippings are thrown away from the operator. For the other units, cut from right to left. Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward- backward 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: + Proper adherence of explained trimming techniques + What vegetation is cut + Where vegetation is cut For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.
OPERATING INSTRUCTIONS DECORATIVE TRIMMING Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more. Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 28). Fig. 28 YM26BC ONLY: USING THE CUTTING BLADE WAR N IN G « Always wear eye, = hearing, foot, body protection and the shoulder strap to reduce the risk of injury when operating this unit. WARN ING … Do notuse the “ cutting blade for edging or as an edger. Severe personal injury to yourself or others can result. Before operating the unit with the cutting blade, stand in the operating position (Fig. 29). Refer to Holding the Trimmer. Cutting Blade Operating Tips To establish a rhythmic cutting procedure:
- Plant feet firmly, comfortably apart. + Bring the engine to full throttle before entering the material to be cut. At full throttle the blade has maximum cutting power and is less likely to bind, stall or cause blade thrust (which can result in serious personal injury to the operator or others). WAR N IN G « Blade thrust may “ occur when the Spinning blade contacts an object that it does not immediately cut. Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any direction, and possibly lose control of the unit.
