For safe use of your product
WARNING
Remove foreign objects and obstructions before working with the
product
Before starting work, check the area where you will be working and remove any small stones and em pty cans likely to rico chet off th e cutting
attachment, as well as any pieces of string or wire that might become
twisted around the cutting attachment.
An accident or serious injury can occur if foreign objects ricochet off the cut-
ting attachment or wire and other materials twisted round the product spring
off it.
Do not hold the cutting attachment up when working with the product
Do not hold the cutting attachment up while y ou work. You must not work with the cuttin g attachments raised a bove
knee level.
Raising the cutting attachm ent above knee level bri ngs the plan e of rotation clo ser to the face , and any objec ts that fly off the
cutting attachments could cause an accident or serious injury.
Turn off the engine immediately if anything goes wrong
In the following situations, turn off the engine immediately and ensure that the cutting attachments have stopped before checking each area of the product. Replace any damaged parts.
If the cutting attachment hits a rock, tree, post, or other such obstruction while you work.
If the product suddenly starts to vibrate abnormally.
Continuing to use parts when they are damaged could lead to an accident or serious injury.
Kickback
The phenomenon that occurs if the trimmer blade
comes into contact with a tree, post, rock or other ha rd
object while rotating at high spe ed and rea cts by rec oiling powerfully and instantaneously is known as kickback.
Causing kickback can resul t in a loss of control over the
product and is highly dangerous.
In particular, if the front-right quadrant of the trimmer
blade (B) strikes a shrub or other such object, the trimmer blade will cause th e product to recoil sharply backwards to the right.
To prevent kickback, do not trim from left to right. Be
careful to ensure that the trimm er blade doe s not strik e
any hard objects.
When trimming, ensure that the object you are cutting
meets the portion of the blade 1 /3 in from the front edge
on the left-hand side (A).
Failure to do so could cause an injury or fatal accident.

WARNING
Use correct blades
Serious injury may result from the improper use of
blades. Read and comply with all safety instructions
listed in this manual.
Use only cutting attachments recommended by YAMABIKO CORPORATION.
The type of blade used mus t be matched to the type and
size of material cut. An improper or dull blade can c ause
serious personal injury. Blades must be sharp. Dull
blades increase the chance of kick-out and injury to
yourself and bystanders.
Plastic/Nylon Grass/Weed Blades may be used
where ever the nylon line head is used. Do not use
this blade for heavy weeds or brush.
The 3 cutter blade is designed especially to cut
weeds and grass. To avoid injury due to kic kba ck or
blade fracture, do not use the 3 cutter blade to cut
brush or trees.
8 Tooth Weed/Grass Blade is designed for gras s, garden debris and thick weeds. Do not use this blade for
brush or heavy woody growth, 19 mm diameter or
larger.
80 Tooth Brush Blade is designed for cutting brush
and woody growth up to 13 mm diameter.
22 Tooth Clearing Blade is designed for dense thickets and saplings up to 64 mm diameter.
Inspect blade before use
Pieces from a cracked metal blade can fly off during operation. Inspect metal blades for cracks before each use.
Discard cracked blades no matter how small the crack.
Cracked blades can be the resul t of th e mi sus e or im proper sharpening.
Damaged or shattered bl ades can cause accidents and se-
rious injury.
Reaction forces
Be sure you understand the reaction forces of push and
pull, and kickback described in this manual, and how
these forces may affect your balance in the operation of a
unit.
Failure to do so could cause an injury or fatal accident.
2.With nylon line cutting head
WARNING

Failure to do so could lead to an accident or injury.
Do not trim near cars or pedestrians
Use extreme caution when operating over bare spots and
gravel, because the line can throw small rock particles at
high speeds. The shield on the unit cannot stop objects
which bounce or ricochet off hard surfaces.
Failure to do so could lead to an accident or serious injury.
Avoid wire
Do not trim in any area where there are broken strands of
fencing wire. Remove the brok en pieces of wire, or g ive the
area wide berth. Wear proper saf ety protection. Do not cut
where you cannot see what the cutting device is cutting.

The basic cutting actions
The basic cutting actions pictured are:
Trimming, scything, scalping and lawn edging.
These actions are as follows:
25
Trimming operation
1. Angle to wall
2. Debris
3. Knife si de raised
4. Angle to ground
Trimming
This is feeding the trimmer carefu ll y into the material you wish to
cut. Tilt the head s lightly to direc t the debris aw ay from yo u. If cutting up to a barrier such as a fence, wall or tree, approach from
an angle where any debris ric ocheti ng off the barrier will fly away
from you.
Move the nylon lin e cutti ng hea d slow ly un til the grass i s cut r ight
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 li ne cutting head near the bottom of the weed
never high up, which could cause the weed to chatter and catch
the line. Rather than cu t th e weed rig ht th rough, just use t he 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 ha ck or cho p dow n the gra ss. Ti lt the n ylon l ine
cutting head to direct the debris away from you on the scything
stroke. Then return without cutting grass f or another s troke. If you
are well protected and do n ot care whether s ome debris is thrown
in your direction, you may scythe in both directions.
A: Scalping B: Edging
1
2
Nylon line cutting head rotates anticlockwise.
The knife will be on the left side of the shield.
1. Debris
2. Cut on this side
Scalping and edging
Both of these are done with the nylon line cutting head tilted at a
steep angle. Scalping is removing top growth, leaving the earth
bare. Edging is trimming the grass ba ck wher e 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 dir t and s t on e, w i ll not co me b ac k t owa r ds yo u ev en if
it ricochets off the hard surface.
Although the pictures show ho w 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 ny lon 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 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 cutt ing head is he ld flat to the grou nd 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.
26
Do not trim near cars or pedestrians.
Trimming operation
Always wear proper eye protection against thrown objects.
Objects can bounce up at you from the ground under the shield,
or ricochet off any nearby hard surface.
Do not trim at high spee d near roadways when there is traffic, or
in places where there are pedestrians. If you must trim where
people are in the zone of risk use a much lower or reduced
speed, by using a partial trigger setting. Do not use full throttle.
Do not push the line into tough weeds, trees, or wire fences.
Pushing the line into chicken wire, chain link fencing or thick
brush can result in sn apped-off line ends being h urled back a t the
operator. The proper way is to cut right up to a barrier, such as
any of those me ntione d, but never run the line into or throu gh the
obstruction. Do not cut closely to obstruction or barrier.
Line pushed into wire fencing will snap off.
Avoid nylon line contact with broken wire fencing. Pieces of wire
broken off by the trimmer can be hurled at high speeds.
Avoid wire
Basic trimming operation with metal blade
WARNING
Please observe the following instructions when trimming.
Ensure that the trimmer blade does n ot come into c ontact with hard obs tructions such a s stone, m etal, or concrete.
If the blade hits an obstruction, tur n off the en gine imme diat ely and ensure that the blade has
stopped before checking the blade and shield for damage.
Never use cracked blades, as they could fly off while you are working.
Check to ensure that the trimmer blade has been tightened securely in place.
Replace the shield if it is damaged or cracked.
Replace the trimmer blade nut when it becomes worn.
Failure to do so could lead to an accident or serious injury.

Always use the blade suited for the job.
Do not allow the t rimme r blade to co me into contac t with har d
obstructions such as stone, concrete or metal.
Do not cut into the ground with the blade.
If the blade hit s an obstruct ion, turn the engi ne off immediately
and ensure that the trim mer blade has stop ped rotating before
checking the blade and shield for damage.
Do not operate with a dull, b ent, fractured or discoloured bla de
and worn or damaged nut.
Never use a crac ked trimmer blade as it could shatte r off while
you are working.
Do not run engine at full throttle without a load.
Remove all foreign objects from work area.
Do not operate brushcutter without shoulder harness and
shield.
Wires can catch and flap around
Scything weeds
This is cutting by swing ing the cutti ng att achm ent in a lev el arc . It
can quickly clear are as of field grass an d weeds. Scyth ing should
not be used to cut large, tough weeds or woody growths.
If a sapling or shrub binds the cu ttin g atta ch me nt, do not use the
cutting attachment as a lever to free the bind, because this will
cause cutting attachment failure.
Instead, shut off the engine an d push th e sa pling or shrub to free
the blades.
Do not use a cracked or damaged blade.
