Trimming operation
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 nylon line cutting 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 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 cutting head 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 sweep-
ing 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 ny-
lon line cutting 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 di-
rections.
Scalping and edging
 Both of these are done with the nylon line cutting head tilted at 
a steep angle. Scalping (A) is removing top growth, leaving the 
earth bare. Edging (B) 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 op-
erator 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 line cutting head 
so that contact is made on the part of line circle where the line 
is moving away from you and the shield (See appropriate pic-
ture). 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 cutting head 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 unit, and you will use up a lot 
of line.
 Nylon line cutting head rotates anticlockwise. The knife will be 
on the left side of the shield.
