Tip of the line does the cutting. Line crowded into work area. Mowing Right Wrong S The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fences. S For trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially: S During light duty cutting. S Near objects around which the line can wrap such as small posts, trees or fence wire. S For mowing or sweeping, use full throttle for a good clean job. TRIMMING -- Hold the bottom of the trimmer head about 3 inches (8 cm) above the ground and at an angle. Allow only the tip of the line to make contact. Do not force trimmer line into work area. Trimming 3 inches (8 cm) above ground SCALPING -- The scalping technique removes unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 3 in. (8 cm) above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique increases line wear. Scalping SWEEPING -- The fanning action of the rotating line can be used to blow away loose debris from an area. Keep the line parallel to and above the area surface and swing the tool from side to side. Sweeping OPERATING INSTRUCTIONS FOR USE WITH WEED BLADE 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 the spinning blade contacts an object that it does not cut. This contact causes the blade to stop for an instant and then suddenly move or "thrust" away from the object that was hit. The "thrusting" reaction can be violent enough to cause the operator to be propelled in any direction and lose control of the unit. The uncontrolled unit can cause serious injury if the blade contacts the 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. MOWING -- Your trimmer is ideal for mowing in places conventional lawn mowers cannot reach. In the mowing position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the tool. S Cut only grass, weeds, and woody brush up to 1/2 inch (1 cm) in diameter with the weed blade. Do not let the blade contact material it cannot cut such as stumps, rocks, 10
