Trimming operation
Basic trimming operation with nylon line cutting head
Adjusting nylon line
 Do not rotate the nylon line cutting head at more than 10000 r/
min.
 When releasing nylon line from spool, hit tap knob of spool
against the ground surface lightly at rotation speed lower than
4500 r/min.
 Cut off knife on the shield adjusts cutting swath automatically
by cutting nylon lines evenly when attachment starts rotating.
 When operating with less than maximum cutting swath, cut
two nylon lines in equal lengths.
 When nylon line becomes shortened, hit tap knob (A) of spool
against the ground surface lightly and the line is released from
spool to come out.
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.
1. Angle to wall
2. Debris
3. Knife side raised
4. Angle to ground
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.
WARNING
 Serious injury may result from the improper use of cutting attachment. Read and comply with all safety instructions
listed in this manual.
 Use only cutting attachments recommended by YAMABIKO Corporation.
 Excessive nylon line beyond cut off knife could fly off when the nylon line cutting head starts rotating after adjust-
ment of nylon line length.
Failure to do so could lead to an accident or serious injury.
