RULES FOR SAFE OPERATION
(WITH NYLON LINE CUTTING HEAD)
The basic cutting actions pictured are: Trimming, scything, scalping and lawn edging. These actions are as follows:
TRIMMING: This is feeding the trimmer carefully into the material you wish to cut. Tilt the head slightly to direct the debris away from you. If cutting up to a barrier such as a fence, wall or tree, approach from an angle where any debris ricocheting off the barrier will fly away from you. Move the line head or line disc slowly until the grass is cut right up to the barrier, but do not jam (overfeed) the line into the barrier. If trimming up to wire mesh or chain link fencing, be careful to feed only up to the wire. If you go too far, the line will snap off around the wire.
Trimming can be done to cut through weed stems one at a time. Place the nylon line cutter near the bottom of the weed never high up, which could cause the weed to chatter and catch the line. Rather than cut the weed right through, just use the very end of the line to wear through the stem slowly.
SCYTHING: This is the cutting or mowing of large grassy areas by sweeping or swinging the trimmer in a level arc. Use a smooth, easy motion. Do not try to hack or chop down the grass. Tilt the line head or line disc to direct the debris away from you on the scything stroke. Then return without cutting grass for another stroke. If you are well protected and do not care whether some debris is thrown in your direction, you may scythe in both directions.
Scalping | Edging |
SCALPING AND EDGING: Both of these are done with the line head or line disc tilted at a steep angle. Scalping is removing top growth, leaving the earth bare. Edging is trimming the grass back where it has spread over a pavement or driveway. During both edging and scalping, hold the unit at a steep angle in a position where the debris, and any dislodged dirt and stone, will not come back towards you even if it ricochets off the hard surface.
Although the pictures show how to edge and scalp, every operator must find for himself the angles which suit his body size and cutting situation.
Debris
Cut on this side
Nylon line head or disc rotates anticlockwise. The knife will be on the left side of the shield.
For nearly all cutting, it is good to tilt the nylon cutter so that contact is made on the part of line circle where the line is moving 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 toward you. If the nylon line cutter is held flat to the ground so that cutting occurs on the whole line circle, debris will be thrown at you, drag will slow the engine, and you will use up a lot of line.
WARNING DANGER
