OPERATING POSITION ALWAYS WEAR: S Shoulder strap pad should be centered on your left shoulder and danger sign centered on your back. S Maintain full weight of tool on left shoulder. S Without bending over, keep the blade near and parallel to the ground and not crowded into material being cut. OPERATING INSTRUCTIONS FOR BRUSHCUTTER ATTACHMENT S Blade Thrust is a reaction that only occurs when using a bladed unit. This reaction can cause serious injury such as amputation. Carefully study this section. It is important that you understand what causes blade thrust, how you can reduce the chance of its occurring, and how you can remain in control of unit if blade thrust occurs. S WHAT CAUSES BLADE THRUST -- Blade Thrust can occur when spinning blade contacts an object that it does not cut. This contact causes blade to stop for an instant and then suddenly move or "thrust" away from object that was hit. The "thrusting" reaction can be violent enough to cause operator to be propelled in any direction and lose control of unit. The uncontrolled unit can cause serious injury if blade contacts operator or others. S WHEN BLADE THRUST OCCURS 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. By using the unit properly, the occurrence of blade thrust will be reduced and the operator will be less likely to lose control. Heavy, Long Pants Boots Eye Protection Cut from your left to your right. NOTE: This brushcutter attachment is not designed for use with electric powerheads. When operating unit with brushcutter attachment, clip shoulder strap onto upper shoulder strap clamp, stand as shown and check for the following: S Wear eye protection and heavy clothing. S Keep arms extended with right hand holding the trigger handle of powerhead. S Keep left arm extended with left hand hold- ing the handlebar. S Keep unit below waist level. S Cut only grass, weeds, and woody brush up to 1/2 inch (1 cm) in diameter with weed blade. Do not let blade contact material it cannot cut such as stumps, rocks, fences, metal, etc., or clusters of hard, woody brush with a diameter greater than 1/2 inch (1 cm). S Use a sharp blade. A dull blade is more likely to snag and thrust. S Cut only at full throttle. The blade will have maximum cutting power and is less likely to bind or stall. S "Feed" the blade deliberately and not too rapidly. The blade can thrust away if it is fed too rapidly. S Cut only from your left to your right. Cutting on right side of the shield will throw debris away from the operator. S Use the shoulder strap and keep a firm grip on the unit with both hands. A properly ad- justed shoulder strap will support the weight of the unit, freeing your arms and hands to control and guide the cutting motion. S Keep feet comfortably spread apart and braced for a possible sudden, rapid thrust of unit. Do not overreach. Keep firm footing and balance. 7
