CUTTING METHODS _WARNING: Use minimum speed and do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), which can damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard. • The tip of the line does the cutting. You will achieve the best performance and minimum line wear by not crowding the line into the cutting area. The right and wrong ways are shown below. Tip of line does the Line crowded into • During light duty cutting. • Near objects around which the line can wrap such as small posts, trees or fence wire. TRIMMING - Hold the bottom of the trimmer head about 3 inches (8 cm) above the ground and at an angle. AItow only the tip of the line to make contact with vegetation. Do not force trimmer line into work area. Trimming (8 cm) above ground SCALPING - The scalping technique removes unwanted vegetation down to the ground. Hold the bottom of the trimmer head about 3 inches (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 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. Mowing Right • The line wilt 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. • For trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially: 14 SWEEPING - The fanning action of the rotating line can be used to blow away toose debris from an area. Keep the tine parallel to and above the area surface and swing the tool from side to side.
