25Trimming operationBasic trimming operation with nylon line cutting headThe basic cutting actions The basic cutting actons pictured are:Trimming, scything, scalping and lawn edging.These actions are as follows:TrimmingThis is feeding the trimmer carefully into the material you wish tocut. Tilt the head slightly to direct the debris away from you. If cut-ting up to a barrier such as a fence, wall or tree, approach froman angle where any debris ricocheting off the barrier will fly awayfrom you.Move the nylon line cutting head slowly until the grass is cut rightup to the barrier, but do not jam (overfeed) the line into the barri-er. If trimming up wire mesh or chain link fencing, be careful tofeed only up to the wire. If you go too far, the line will snap offaround the wire.Trimming can be done to cut through weed stems one at a time.Place the nylon line cutting head near the bottom of the weednever high up, which could cause the weed to chatter and catchthe line. Rather than cut the weed right through, just use the veryend of the line to wear through the stem slowly.ScythingThis is the cutting or mowing of large grassy areas by sweepingor swinging the trimmer in a level arc. Use a smooth, easy mo-tion. Do not try to hack or chop down the grass. Tilt the nylon linecutting head to direct the debris away from you on the scythingstroke. Then return without cutting grass for another stroke. If youare well protected and do not care whether some debris is thrownin your direction, you may scythe in both directions.Scalping and edgingBoth of these are done with the nylon line cutting head tilted at asteep angle. Scalping is removing top growth, leaving the earthbare. Edging is trimming the grass back where it has spread overa pavement or driveway. During both edging and scalping, holdthe unit at a steep angle in a position where the debris, and anydislodged dirt and stone, will not come back towards you even ifit ricochets off the hard surface.Although the pictures show how to edge and scalp, every opera-tor must find for himself the angles which suit his body size andcutting situation.For nearly all cutting, it is good to tilt the nylon line cutting headso that contact is made on the part of line circle where the line ismoving away from you and the shield (See appropriate picture).This results in the debris being thrown away from you.Tilting the head to the wrong side will shoot the debris towardyou. If the nylon line cutting head is held flat to the ground so thatcutting occurs on the whole line circle, debris will be thrown atyou, drag will slow the engine, and you will use up a lot of line.1.
