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 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 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 and EDGING : Both of these are done with the
line head 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.
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 guard (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.
USE ONLY FLEXIBLE, NON-METALLIC LINE
