[. . . ] FRONT HANDLE - The Front (loop) handle is loosely assembled to the Drive Shaft assembly and must be positioned for proper cutting attitude and operator comfort. DRIVE SHAFT ASSEMBLY - Includes the Gear Housing assembly, flex drive cable and Safety Decal. NYLON CUTTER HEAD - Contains replaceable nylon trimming line that advances when the trimmer head is tapped against the ground while the head is turning at normal operating speed. CUT-OFF KNIFE - Automatically trims line to the correct length: 5" after head is tapped on the ground. If trimmer is operated without a cut-off knife the line will become too long, the engine will overheat and engine damage may occur. Mounts on the Gear Housing Assembly just above the cutting attachment. Helps protect the operator by deflecting debris produced during the trimming operation. During acceleration, press trigger gradually for best operating technique. SPARK ARRESTOR - CATALYTIC MUFFLER / MUFFLER -The muffler or catalytic muffler controls exhaust noise and emission. The spark arrestor screen prevents hot, glowing particles of carbon from leaving the muffler. I-30 RECOIL STARTER/HANDLE - i-30 spring-assisted recoil starter requires 30% less pulling force than standard recoil starter. DO NOT use this blade for brush or heavy woody growth, 19 mm (3/4 in. ) diameter or larger. GRASS TRIMMER/BRUSH CUTTER OPERATOR'S MANUAL 15 80 Tooth Brush Blade (P/N 69500120331) is designed for cutting brush and woody growth up to 64 mm (2-1/2 in. ) diameter. 22 Tooth Clearing Blade (99944200130) is designed for dense thickets and saplings up to 64 mm (2-1/2 in. ) diameter. Use Shoulder/Waist Harness (P/N 99944200200) Use of the Shoulder/ Waist Harness is recommended for ALL Trimmer/Brush Cutter use. The Shoulder/Waist Harness suspends the trimmer from the operator's shoulder and reduces operator fatigue. The restrictive harness enhances operator safety by reducing the possibility of blade contact with the operator's hands and feet. NOTE In case of Emergency, pull up on the Quick Release Collar to disconnect the trimmer from the harness. 16 FUEL Fuel Requirements Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J. A. S. O. Echo brand premium Power Blend TM Universal 2-Stroke Oil meets these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-EGD and J. A. S. O. FC certified oil, such as Echo premium Power Blend TM, will void the two-stroke engine warranty. (Emission related parts only are covered for two years, regardless of two-stroke oil used, per the statement listed in the Emission Defect Warranty Explanation. ) IMPORTANT Echo premium Power Blend TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo engines sold in the past regardless of ratio specified in those manuals. Fill an approved fuel container with half of the required amount of gasoline. Install fuel container cap and wipe any spilled fuel from container and surrounding area. [. . . ] Pull both lines out and trim to cut-off knife length. SHARPENING METAL BLADES Three styles of metal blades are approved for use on the ECHO Brush Cutter. Before sharpening, CLOSELY inspect blade for cracks (look at the bottom of each tooth and the center mounting hole closely), missing teeth and bending. When sharpening a blade, always remove the same amount of materials from each tooth to maintain balance. A blade that is not balanced will cause unsafe handling due to vibration and can result in blade failure. [. . . ]
