Vibration and cold
It is believed that a condition called Raynaud's Phenomenon which affects the fingers of certai n individuals may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingli ng 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 performing vigorous
arm exercises during frequent work brea ks, and also 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.
If you experience discomfort redness and swelli ng of
the fingers, followed by whitening and loss of feeling,
consult your physician before exposi ng yourself further
to cold and vibration.
Failure to observe th ese instructi ons could result in damage
to your health.
Repetitive stress injuries
It is believed that over-using the muscles and tendons of
the fingers, hands, arms and shoulders may cause soreness, swelling, numbness, weakness and extreme pain to
the areas just mentioned. Certai n repetitive hand activities
may put you at a high risk for developing a repetitive
stress injury (RSI).
To reduce the risk of RSI, do the following:
Avoid using your wrist in a bent, extended or twisted
position.
Take periodic breaks to minimize repetition and rest
your hands. Reduce the speed and force in which you
do the repetitive movement.
Do exercises to strengthen hand and arm muscles.
See a doctor if you feel tingling, numbness or pain in
your fingers, hands, wrists or arms. The sooner RSI is
diagnosed, the more likely permanent nerve and muscle
damage can be prevented.
Failure to observe th ese instructi ons could result in damage
to your health.
Proper training
Do not permit operation without proper training and protective equipment.
Be thoroughly familiar with the controls and proper use of unit.
Know how to stop the unit and shut off the engine.
Know how to unhook a harnessed unit quickly.

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 re-
move any small stones an d em pty cans lik ely to r icoche t off the cu tting
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 you work. You m ust not work with the cutting attac hments raised above
knee level.
Raising the cutting attachmen t above knee level brings the plane of rotatio n closer t o the face, and an y objects 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 recoiling powerfully and instantaneously is known as kickback.
Causing kickback can result in a los s 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 p r oduc t to rec oil sha r ply ba ckwards to the right.
To prevent kickback, do not trim from left to right. Be
careful to ensure that the trimmer blade does no t strike
any hard objects.
When tri mming, 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.
12
For safe use of your product
Precautions concerning the cutting attachment
1.With metal blade
2.With nylon line cutting head
DANGER
Always stop the engine whe n a cut ting attac hment ja m occu rs. Do not attem pt to remov e an ob ject ca using a jam if th e
engine is running. Severe injury can occur if a jam is removed and the cutting attachment suddenly starts.
WARNING
Use correct blades
Serious injury may result from the improper use of
blades.
Read and comply with all sa fety instructions listed in
this manual.
The 3 cutter blade is designed especially to cut weeds
and grass. To avoid i njury due to kickbac k or blade fracture, do not use the 3 cu tter blade to cu t brush o r trees.
Use only cutting attachments recommended by KIOR-
ITZ CORPORATION.
Damaged or shattered blades can cause accidents and se-
rious injury.
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 the mis use or im proper sharpening.
Damaged or shattered blades 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.
WARNING
Use correct cutting attachment
Serious injury may result from the improper use of cut-
ting attachment.
Read and comply with all sa fety instructions listed in
this manual.
Use only cutting attachments recommended by KIOR-
ITZ CORPORATION.
Use only nylon line cutting hea d. Do not use a ny type of
metal blade.
Failure to do so could lead to an accident or serious injury.
Excessive nylon line beyond cut off knife could fly off
when the nylon line cutti ng head starts rota ting after adjustment of nylon line length.
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 broken pieces of wire, or give the
area wide berth. Wear proper saf ety protec tion. Do no t cut
where you cannot see what the cutting device is cutting.
Failure to do so could lead to an accident or serious injury.
CAUTION
Use only flexible, non-metallic line recommended by KIORITZ CORPORATION.

Installation of bracket
Fit bracket to mounting portion of angle transmission and fix the
bracket by holding fittin g pl ate p res sed from ben eat h and tighten
4 bolts (M5×25) lightly.
Get notches and convexes of fitting plate to face corresponding
convexes and concaves of bracket, and fix bracket tightening 4
bolts (M5×25) securely.
There are two types of shields: namely one used exclusively for
nylon line cutting h ead and a nother one used ex clusive ly for metal blade. When metal blade is used, use the shield for metal
blade.
Installing blade
Inspect blades before installation. Check for sharpness.
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.
Blade retainer, blade, lower blade retainer, cup and nut finger
tight.
Insert locking tool into a hole located on the right side of angle
transmission while forcing retainer spring to the left side. Insert
locking tool further into b lade retainer fixin g slot to fix output s haft.

Preparing the fuel
Fuel
Fuel is a mixture of regular grade petrol and an air-cooled 2-
stroke engine oil of reputable brand name.
Minimum 89 Octane unl eaded petrol is recommended . Do not
use fuel containing methyl alcohol or more than 10 % of ethyl
alcohol.
Recommended mixture ratio; 50 : 1 (2 %) for ISO-L-EGD
Standard (ISO/CD 13738), JASO FC,FD grade and ECHO
Premium 50 : 1 o il.
- Do not mix directly in engine fuel tank.
- Avoid spilling petrol or oil. Spilled fuel should always be
wiped up.
- Handle petrol with care, it is highly inflammable.
- Always store fuel in approved container.
Fuel supply
Always refuel in a well ventil ated location. Do not pour fuel in-
doors.
Place the produc t an d the refuelling tank on the ground when
performing the refuelling operation. Do not refuel the product
on the loading platform of a truck, or in other such places.
Always ensure that the fuel level remains below the shoulder
level of the fuel tank when refuelling.
There is a difference in pressure between the fuel ta nk and the
outside air. When refu elling, loosen the fuel ta nk cap slightly to
eliminate the difference in pressure.
Always wipe up any fuel spills.
Move at least 3m away from where you refueled before you
start the engine.
Keep the refuelling tank in a shaded area away from fire.
DANGER
Fuel is highly inflammable and ther e is a risk of fire if it is handled incorrectly. Carefully read
and observe the precautions in the sectio n of this manual title d "For safe use of you r product".
Once the refuelling is complete, securely tighten the fuel tank cap and do not forget to
check that there are no leak s or discharges of fuel from th e fuel pipe, fuel system gromm ets,
or around the fuel tank cap. If you do find fuel leaks or discharges, stop using the product
immediately and contact your ECHO DEALER to have it repaired.
If the fuel ignites, it could cause burns and fire.
CAUTION
There is difference in pressure between the fuel tank and the outside air. When refuelling, loosen the fuel tank cap
slightly to eliminate the difference in pressure.
Otherwise, fuel may get spewed.

3. For even load on both sides of shoulder, joggle the unit on
the shoulder a couple of times.
4. It is preferable to conn ect the strap to the hangers lo cated on
the loop handle th e left or right knapsack band and adjust the
length of the strap to maintain a comfortable operation.
Increase engine speed as necessary, heavy weeds will require
more power than cutting grass. - Small trees or heavy brush can
be cut using the circ ular saw. - T he 3 cutte r blade sh ould be u sed
only for cutting grass, brush or for heavy weed control.
Hold the front handle (loop handle) and rear handle both hands.
When cutting weeds or g rass, sw ing th e bla de ri ght an d lef t in
an arc as you mo ve forward.
The blade rotates anticlockwise, so it is necessary to cut the
object from the right to the left.
The manner of walking is as follows: - Place the right foot in
front of the left foot without fail. - Step the right foot forward
firstly and secure y our footin g. - And th en follow the left f oot to
the behind of the right foot.
Avoid striking any obstruction such as rocks, stones or tree
stumps which can damage the blade. - In the event that the
blade strikes an obstructi on or is otherwise prevented from rotating in normal op erat ion , the clutch will slip to prevent possible engine damage. - In this case, stop the engine, free the
blade and then start the operation again.
Do not cut into the ground.
Do not run the unit unl oaded at full thrott le to av oid dama ge to
the engine.
Should the unit be operated for an extended period of time in
high temperatures, the angle transmission may become very
hot. If it is too hot to touch, allow the unit to cool down, check
the lubricant as the i nstruc tion an d cont inue to operate if in o rder.
DANGER
Always stop the engine whe n a cut ting attac hment ja m occu rs. Do not attem pt to remov e an ob ject ca using a jam if th e
engine is running. Severe injury can occur if a jam is removed and the cutting attachment suddenly starts.

Trimming operation
Basic trimming operation with nylon line cutting head
The basic cutting actions
The basic cu tting actons pictured are:
Trimming, scything, scalping and lawn edging.
These actions are as follows:
Trimming
This is feeding the trimmer carefu ll y int o the mate rial you wish to
cut. Tilt the head slig htly to direc t the debris awa y from you. 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 wil l fly away
from you.
Move the nylon lin e cutti ng hea d slowly 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 line cutting head near the bottom of the weed
never hig h u p, w hic h c o ul d ca us e the w e ed t o ch a tte r and c at c h
the line. Rather than cu t the w eed rig ht throu gh, jus t 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 hack or cho p down th e gra ss. Tilt t he nyl on line
cutting head to direct the debris away from you on the scything
stroke. Then return w ithout cutting grass f or another s troke. If you
are well protected and do not care whet her some debris is thrown
in your direction, you may scythe in both directions.
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 where it h as 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 di r t an d s t on e, w ill n ot co me b ac k t owa rd s yo u ev en if
it ricochets off the hard surface.
Although the pictures show ho w to edg e and sc alp, 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 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 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 cutting head is held fl at to the ground s o 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.

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 speed 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 at the
operator. The proper way is to cut right up to a barrier, such as
any of those mentio ne d, but never run the line into or throu gh 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.

Do not trim near cars or pedestrians.
Line pushed into wire fencing will snap off.

WARNING
Please observe the following instructions when trimming.
Ensure that the trimmer blade doe s not come into c ontact with hard obs tructions such a s stone, m etal, or concrete.
If the blade hits an obstruction, turn off the engine imme diately 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.
27
Trimming operation
Use correct blade
Always use the blade suited for the job.
Do not allow the t rimme r blade to come into co ntact w ith har d
obstructions such as stone, concrete or metal.
Do not cut into the ground with the blade.
If the blade hit s an obstruction , turn the engine o ff immediately
and ensure that the trim mer blade has stopped rotating before
checking the blade and shield for damage.
Do not operate with a dull, b ent, fractured or discoloured b lade
and worn or damaged nut.
Never use a crac ked trimmer blade as it could shatte r off while
you are worki ng.
Do not run engine at full throttle without a load.
Remove all foreign objects from work area.
Do not operate brushcutter without shield.
Scything weeds
This is cutting by s wing ing the cutting att achment in a level arc. I t
can quickly clear areas of field grass an d weeds. Scything should
not be used to cut large, tough weeds or woody growths.
If a sapling or shrub binds the cu ttin g attachment, 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 sapli ng or shrub to free
the blades.
Do not use a cracked or damaged blade.
Reaction forces
Push.
The operator may feel the unit push toward him when he tries to
cut the object on right. If he cannot hold the blade in the cut, a
kickback may occur when the blade is pushed out to where the
teeth at the outside furthest point from the operator are cutting.
The blade will "kickback" sideways.
Pull.
The opposite of push. When obj ec t on le ft, th e ope rato r may feel
the unit pull away. Alt hough this p ull type of cu tting may cau se
sawdust to be thrown bac k at the oper ator, it is rec ommended fo r
sawing off heavy brush because the cutting is smoother and
more stable than when the unit pushes.
Inspect blades before use

Trimming operation
Kickback.
If you hit a hard object with the front-right of the trimmer blade,
such as when trimming in both directions, the blade will kick
sharply back to the right. This is a phenomenon known as "kick
back", and can cause a seri ous ac cid en t due to the ope rato r los ing control over the product. Take particular care to ensure that
you do not strike any hard object with th e front-right of the trimmer
blade.
Precautions to observe when working
The area within a radius of 15m of the product is a danger
zone. Make sure that there are no children, onlookers, or pets
in this zone. If anyone comes within 15m, turn off the engine
immediately to stop the blade from rotating.
If someone is helping you with the work or you are working to-
gether, identify the way in which you will signal to each other
and work at least 15m apart. You are advi sed to carry a whis tle
in case you need to communicate.
Turn off the engine imm edia tely if th e product s uddenl y starts
to vibrate abnormally. Sudden vibration may be caused by a
problem with a component such as the flywheel, clutch, or
trimmer blade, or by a loose screw or oth er such factor. Do no t
use the product until you hav e identified the cause of the problem and the repair has been completed.
The trimmer blade could fly off unless tightened securely. En-
sure that it is fitted securely in place.
Replace the shield if it is damaged or cracked.
If you work wit h t he ang le tra nsmiss ion in cont act w ith t he su r-
face of the ground, the trimmer blade nut and cup can easily
become worn. Replace them with new parts if this happens.
When you turn off the engi ne, check to ensure that the trim mer
blade has stopped ro tating before you lower the product to the
ground. Even if the engin e ha s been turned o ff, the bl ade can
still cause an injury while free-wheeling.
The silencer will remain hot for some tim e after the engine has
been turned off. Carry the product with the si lencer away from
you to avoid touching it with your body.
When carrying the product, always turn the engine off and fit
the trimmer blade cover over the trimmer blade.
