WARNING
Vibration and cold
It is believed that a condition called Ray naud's Phe nomenon which a ffects the fin gers o f certai n individu als may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning,
followed by loss of colour and numbness in the fingers. The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.
Keep your body warm, especially the head and neck, feet and ankles, and hands and wrists.
Maintain good blood circulation by pe rforming vigoro us arm exerci ses during frequent work brea ks, and als o by
not smoking.
Limit the number of hours of operation. Try to fill each day with jobs where operating the trimmer or other hand-
held power equipment is not required.

the barrier. If trimming up wire mesh or chain link fencing, be
careful to feed only u p to the wire. If y ou go too far, th e line will
snap off around the wire.
Trimming can be done to cut through weed stems one at a
time. Place the nylon line cu ttin g hea d near the bottom of the
weed never high up, which could cause the weed to chatter
and catch the line. Rather tha n cut the weed right through , just
use the very end of the line to wear through the stem slowly.

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 ha ck or c ho p d own th e g r as s. T ilt the ny lon line cutting head to direct the debris away from you on the
scything stroke. Then return w it hou t cutt ing gras s for an oth er
stroke. If you a re well protected and do not ca re whether some
debris is thrown in your direction, you may scythe in both directions.
Both of these are done with the nylon line cutti ng head tilted at
a steep angle. Scalp ing (A) is removing top growth, leaving the
earth bare. Edging (B) is trimming the grass back where it has
spread over a pavem ent o r drive way. During both ed ging a nd
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 he ad
so that contact is m ade on th e part of li ne circle where th e 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 wron g side wil l shoot the debris to ward
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 wil l slow th e engine, an d you will us e up a
lot of line.
Nylon line cutting head rotates ant iclockwise . The knife wi ll be
on the left side of the shield.
1. Debris
2. Cut on this side
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 snapp ed-off lin e ends be ing hurled back at
the operator. The proper way is to cut right up to a barri er, such
as any of those mentioned, but never run the line into or
through the obstruction. Do not cut closely to obstruction or
barrier.
Avoid nylon line contact with broken wire fencing. Pieces of
wire broken off by the trimmer can be hurled at high speeds.

Trimming operation
Basic trimming operation with metal blade
WARNING
Please observe the following instructions when trimming.
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.
Do not cut into the ground with the blade.
Do not operate with a dull, bent, fractured or discoloured blade and worn or damaged nut.
Do not run engine at full throttle without a load.
Failure to do so could lead to an accident or serious injury.
Use only cutting attachments recommended by YAMABIKO CORPORATION.
The type of blade used must be matched to the type and size of material cut. An improper or dull blade can cause
serious personal injury. Bla des must be sharp. Dull bla des increase the chance of kick-out and injury to you rself 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 espec ially to cut weeds and grass. To avoi d injury due to kickback or blade fract ure,
do not use the 3 cutter blade to cut brush or trees.
8 Tooth Weed/Grass Blade is designe d for grass, garde n debris and thick weeds. Do not use this bla de for brush
or heavy woody growth, 19 mm diameter or larger.
22 Tooth Clearing Blade is designed for dense thickets and saplings up to 64 mm diameter.
80 Tooth Brush Blade is designed for cutting brush and woody growth up to 13 mm diameter.
Damaged or shattered blades can cause accidents and serious injury.
Kickback
The phenomenon that occurs if the trimmer blade co mes into
contact with a tree, post, rock or other hard object while rotating at high speed and reacts by recoiling powerfully and
instantaneously is known as kickback.
Causing kickback can result 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 the product to recoil sharply backwards to the
right.
To prevent kickback, do not trim from left to right. Be careful to ensure that the trimmer blade does not strike 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.
Scything weeds
This is cutting by swinging the cutting attachment in a level
arc. It can quickl y cle ar areas of fiel d gras s and w eeds . Scyth ing should not be used to cut large, tough weeds or woody
growths.
If a sapling or shrub binds the cutting attachment, do not use
the cutting attachm ent as a lever to free the bin d, because this
will cause cutting attachment failure.
Instead, shut off the engine and push the sapling or shrub to
free the blades.

Carburettor adjustment
WARNING
YOU MAY ADJUST THE IDLE SPEED ONLY by turning the idle speed adjustment screw(T).
During carburettor adjustment, the cutting attachment may move. Pay utmost attention and care to the cutting attachment so as not to get injured by the moving cutter.
When carburettor adjustment is completed, the cutting attachme nt should not move at idle speed, othe rwise serious
personal injury may result.
You must NOT carry out any Carbu rettor ad justm ent, ot her tha n the i dle speed. All other adjustments M UST be p er formed by an authorized service dealer, or serious personal injury may result due to malfunction of the engine.
CAUTION
When there is trouble with the carburettor, contact an authorized service dealer.
Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start engine and run several minu tes to bring i t to operating temperature .

Maintenance and care
Cooling system maintenance
IMPORTANT
To maintain proper engine operating temperature, cooling air must pass freely through the cylinder fin area. This
flow of air carries combustion heat away from the engine. Overheating and engine seizure can occur when:
Air intakes are blocked, preventing cooling air from reaching the cylinder.
Dust and grass build up on the outside of the cylinder. This build-up insulates the engine and prevents the heat
from leaving.
Removal of cooling passage b lockages or cleanin g of cylin der fins is con sidered "N ormal Ma intenanc e". Any re sultant fa ilure
attributed to lack of maintenance is not warranted.
Remove dust and dirt from between fins (A).
Before each use, rem ove accum ulated de bris from bottom en-
gine intake grille located between the fuel tank and starter.
Cleaning silencer
Check fuel system
Air intake
Carbon deposits i n silencer (A) will ca use a drop i n engine ou t-
put and overheating. Spark arrestor screen must be checked
periodically. Clean deposits from silencer.
IMPORTANT
Do not remove the silenc er cover. If necessa ry, Please consul t
your dealer.
Check before every use.
After refuelling, make sure fuel does not leak or exude from
around fuel pipe (A), fuel grommet (B) or fuel tank cap (C).
In case of fuel leakage or exuda tio n, there is a danger of fire.
Stop using the machine im me diately and request your dealer
to inspect or replace.
Check spark plug
1. Check plug gap. Correct gap is 0.6 mm to 0.7 mm.
2. Inspect electrode for wear.
3. Inspect insulator for oil or other deposits.
4. If the electrodes or terminal s are worn, or if there are crac ks
in the ceramics, replace them with new parts.
5. Tighten to 15 N·m - 17 N·m (150kgf·cm to 170 kgf·cm).
∗ The spark test (for checking whether the spark plug is spark-
ing) must be carried out by your dealer.

1. Remove plug (B) from angle transmission (A).
2. Add grease, if necessary, using low pressure pump.
NOTE
Use good quality lithium multi grease.
Do not overfill housing.
3. Reinstall plug.
Method to change shield
There are two types of shields: namely the one used exclu-
sively for nylon lin e cutting head and the other one us ed exclusively for metal blade. When metal blade is used, use the
shield for metal blade.
1. Fully loosen the bolt (A) on the right side of the bracket (B)
to slide the shield . The bolt itself can not be removed from the
bracket.
2. Pushing the button (C ), sl ide th e shi eld (D) t o the left an d remove it.
3. Put shield of other type (E) into groove and s lide it to the right

Installing blade (option)
WARNING
Wear heavy duty gloves when working with the trimmer blade.
When replacing the trimmer blade durin g a trimming task, ens ure that the engine is sw itched off and that the blades
have stopped.
When turning the product over to replace the trimmer blade, ensure that the fuel tank cap is securely in place.
Do not attempt to fit the trimmer blade with one hand or without us ing the sock et spa nne r. Fit the trim mer bla de ac curately using the supplied socket spanner and tighten firmly in position.
Do not use any tools other than the provided socket spanner to tighten the blade; a pneumatic or electric tool may
tighten the blade more than necessary and cause the nut or the output shaft to break.
If worn nut and cup for blade are used, there is a danger of blade getting loose. Replace them with new one.
Failure to do so could lead to an injury or serious accident, or cause a fire.
23
Maintenance and care
1. Inspect blades (C) bef ore inst allati on. Chec k for sha rpness .
Dull blades increase the risk of blade kickback reactions.Small cracks can develop into fractures resulting in a
piece of blade flying off during operation. Discard cracked
blades no matter how small the crack.
2. Securely tighten the blade retainer (B), blade, lower blade
retainer (D), cup (E), and nut (F) by hand.
3. Insert locking tool (G) into a hole l ocated on the right s ide of
angle transmission while forcing retainer spring to the left
side.
4. Insert locking too l furth er int o bla de reta iner f ixing s lot (A) to
fix output shaft.
CAUTION
Fix output shaft securely using locking tool in order to
prevent it form rotating when blade is mounted. Otherwise, the blade faste ning n ut w il l n ot b e tightened sufficiently.
Checking the blade
5. Tighten the nut (turn anticlockwise) using a socket wrench
(H). Never fasten whi le app lying yo ur weight . Other wise the
thread of nut could be broken.
Use only blade designa ted for this model by the ma nufacturer.
When a crack i s noticed o n the blade, do not use it but repla ce
with a new one.
Ensure that the blade is correctly fitted in acco rdance with the
instructions.
When the cutting blad e becomes dull due to wear rever se it for
further use.
When chip or bend occurs on the blade, vibration w ill increase.
Replace with new one.
When filing the blade fil e 3 cutting edges evenly using a flat file
as shown in the illu stration. Othe rwise, the bala nce will be los t
and vibration will increase.

Checking the nylon line cutting head
Maintenance and care
1. Make sure each periphery of the 2 retaining paw ls of housing
spreads almost fully up to the oute r perip hery of the respective cover window.
2. Check mount of cutting head on trimmer and tighten if it is
loose.
3. Check the cutter head for def lection o r abnormal noise rota ting it by hand. Deflection or abnormal noise can cause abnormal vibration to occur or mount to trimmer to loosen
during rotation which is dangerous.
4. Inspect cover and tap knob for wear. Whe n s lot appears on
bottom of the tap knob o r when slot appears on cov er bottom
close to outlet for nylon line, replace them with new parts
without fail.
5. Check the cutting hea d for crac k or chip . Replac e parts tha t
show any crack or chip with new ones without fail.
Replacing nylon line
DANGER
Shut down trimmer engine without fail and make sure nylon line cutting head has stopped rotating before starting
replacement procedure.
To do so could lead to an accident or serious injury.
WARNING
Use only flexible, non-metallic line recommended by YAMABIKO CORPORATION.
Failure to do so could lead to an accident or serious injury.
1. Press "retaining pawls" (at two places) inward and remove
cover. It is easier to remove one after another.
2. Remove spool.
3. When nylon line on the spool is almost exhausted, remove
remaining line from spool and wind "new line" according to
the procedures (4) and beyond. When the line on the spool
is "melted and stuck " remove the e ntire line wh ile peeling of f
the "melted and stuck" portion and wind the "removed line"
anew according to procedures (4) and beyond.
4. Bend the line at the point 12 cm away from the middle of
whole length and ho ok the bent portion in to the "notch" o f the
intermediate separator.
5. Wind the line firmly into groove of the spool following "winding direction for the arrow".
25
Maintenance and care
6. When the line is wound to the end hook both line ends into
respective notch of spool for retaining tentatively the line
while leaving line ends approximately 10 cm beyond notch.
7. Align notches of spool for the line with grooves of eyelets
and fit spool into cover.
