Trimming operation
Using shoulder harness
Always mount the trimmer correctly using the shoulder har-
ness.
Buckle waist belt (U-handle version). Belt should be snug.
Attach product to harness.
Loop handle version
Place shoulder harness over left shoulder and adjust
straps so the emergency tab rests just below the waist.
U-handle version
Place shoulder harness over both shoulders and adjust
straps so the connecting point latches as shown.
Check for correct adjustment by moving cutting attachment
along ground.
Re-adjust position of suspension point if necessary.
The shoulder harness is fitted with an emergency release
function. In the event of a fire or other emergency, pull the
emergency tab (A) up to release the product from your
body.
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
WARNING
Serious injury may result from the improper use of cutting attachment. Read and comply with all safety instructions
listed in this manual.
Do not operate with a damaged cutter.
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.
