WARNING!!!

RISK OF DAMAGING HEARING

IN NORMAL CONDITIONS OF USE, THIS MACHINE MAY INVOLVE A DAILY LEVEL

OF PERSONAL EXPOSURE TO NOISE FOR THE OPERATOR EQUAL TO OR

GREATER THAN

85 dB(A)

1. For Safe Operation

EN 2 1. For Safe Operation

1. Never operate a chain saw

when you are fatigued, ill, or

upset, or under the influence of

medication that may make you

drowsy, or if you are under the

influence of alcohol or drugs.

2. Use safety footwear, snug fit-

ting clothing and eye, hearing and

head protection devices.

Use the vibration-proof glove.

3. Keep the saw chain sharp and

the saw, including the AV system,

well maintained. A dull chain will

increase cutting time, and press-

ing a dull chain through wood will

increase the vibrations transmit-

ted to your hands. A saw with

loose components or with dam-

aged or worn AV buffers will also

tend to have higher vibration lev-

els.

4. All the above mentioned pre-

cautions do not guarantee that

you will not sustain whitefinger

diseaseor carpal tunnel syn-

drome.

Therefore, continual and regular

users should monitor closely the

condition of their hands and fin-

gers. If any of the above symp-

toms appear, seek medical advice

immediately.

5. Always use caution when han-

dling fuel. Wipe up all spills and

then move the chain saw at least 3

m from the fueling point before

starting the engine.

6. Eliminate all sources of sparks

or flame (i.e. smoking, open

flames, or work that can cause

sparks) in the areas where fuel is

mixed, poured, or stored.

7. Do not smoke while handling

fuel or while operating the chain

saw.

8. Do not allow other persons to

be near the chain saw when start-

ing or cutting. Keep bystanders

and animals out of the work area.

Children, pets and bystanders

should be a minimum of 10 m

away when you start or operate

the chain saw.

9. Never start cutting until you

have a clear work area, secure

footing, and a planned retreat

path from the falling tree.

10. Always hold the chain saw

firmly with both hands when the

engine is running. Use a firm grip

with thumb and fingers encircling

the chain saw handles.

11. Keep all parts of your body

away from the saw chain when the

engine is running.

12. Before you start the engine,

make sure the saw chain is not

contacting anything.

13. Always carry the chain saw

with the engine stopped, the

guide bar and saw chain to the

rear, and the muffler away from

your body.

14. Always carry the chain saw

with the engine stopped, the

guide bar and saw chain to the

rear, and the muffler away from

your body.

15. All chain saw service, other

than the items listed in the

Owner’s Manual, should be per-

formed by competent chain saw

service personnel. (E.g., if improp-

er tools are used to remove the

flywheel, or if an improper tool is

used to hold the flywheel in order

to remove the clutch, structural

1. For Safe Operation

1. For Safe Operation EN 3

damage to the flywheel could

occur which could subsequently

cause the flywheel to disinte-

grate.)

16. Always shut off the engine

before setting it down.

17. Use extreme caution when

cutting small size brush and

saplings because slender material

may catch the saw chain and be

whipped toward you or pull you

off balance.

18. When cutting a limb that is

under tension, be alert for spring-

back so that you will not be struck

when the tension in the wood

fibers is released.

19. Never cut in high wind, bad

weather, when visibility is poor or

in very high or low temperatures.

Always check the tree for dead

branches which could fall during

the felling operation.

20. Keep the handles dry, clean

and free of oil or fuel mixture.

21. Operate the chain saw only in

well ventilated areas. Never start

or run the engine inside a closed

room or building. Exhaust fumes

contain dangerous carbon

monoxide.

22. Do not operate the chain saw

in a tree unless specially trained to

do so.

23. Guard against kickback.

Kickback is the upward motion of

the guide bar which occurs when

the saw chain at the nose of the

guide bar contacts an object.

Kickback can lead to dangerous

loss of control of the chain saw.

24. When transporting your chain

saw, make sure the appropriate

guide bar scabbard is in place.

1.1 KICKBACK SAFETY PRECAUTIONS FOR

CHAIN SAW USERS

Kickback may occur when

the nose or tip of the guide bar touches an

object, or when the wood closes in and

pinches the saw chain in the cut. Tip contact

in some cases may cause a lightning fast

reverse reaction, kick-

ing the guide bar up

and back towards the

operator.

Pinching the saw

chain along the top of

the guide bar may

push the guide bar

rapidly back towards the operator. Either of

these reactions may cause you to lose control

of the saw, which could result in serious per-

sonal injury.

• Do not rely exclusively on the safety devices

built into your saw. As a chain saw user you

should take several steps to keep cutting

jobs free from accident or injury.

1. With a basic understanding of kickback you

can reduce or eliminate the element of surprise.

Sudden surprise contributes to accidents.

2. Keep a good grip on the saw

with both hands, the right hand on

the rear handle, and the left hand

on the front handle, when the

engine is running. Use a firm grip

with thumbs and fingers encircling

the chain saw handles. A firm grip

will help you reduce kickback and

maintain control of the saw.

3. Make certain that the area in

which you are cutting is free from

obstructions. Do not let the nose

of the guide bar contact a log,

branch, or any other obstruction

which could be hit while you are

operating the saw.

4. Cut at high engine speeds.

5. Do not overreach or cut above

shoulder height.

6. Follow the manufacturer’s

sharpening and maintenance

instructions for the saw chain.

7. Only use replacement bars and

chains specified by the manufac-

turer or the equivalent.

WARNING!

1.2 WORKING WITH TREE SERVICE CHAIN-

SAWS FROM A ROPE AND HARNESS

This chapter sets out working practices to

reduce the risk of injury from tree service chain-

saws when working at height from a rope and

harness.

While it may form the basis of guidance and

training literature, it should not be regarded as a

substitute for formal training.

General requirements working at height

Operators of tree service chainsaws working at

height from a rope and harness should never

work alone.

A competent ground worker trained in appropri-

ate emergency procedures should assist them.

Operators of tree service chainsaws for this work

should be trained in general safe climbing and

work positioning techniques and shall properly

equipped with harnesses, ropes, strops, kara-

biners and other equipment for maintaining

secure and safe working positions for both

themselves and the saw.

Preparing to use the saw in the tree

The chainsaw should checked,

fuelled, started and warmed up

by the ground worker before it is

sent up to the operator in the

tree.

The chainsaw should be fitted

with a suitable strop for attach-

ing to the operator’s harness:

a) choke the strop around the attachment point

on the rear of the saw (A);

b) provide suitable karabiners to allow indirect

(i.e. via the strop) and direct attachment (i.e.

at the attachment point on the saw) of saw to

the operators harness;

c) ensure the saw is securely attached when it is

being sent up to the operator;

d) ensure the saw it secured to the harness

before it is disconnected from the means of

ascent.

The saw should only be attached to the recom-

mended attachment points on the harness.

These may be at mid-point (front or rear) or at

the sides.

Where possible attaching the saw to centre rear

mid-point will keep it clear of climbing lines and

support its weight centrally down the operator’s

spine.

When moving the saw from

any attachment point to

another, operators should

ensure it is secured in the

new position before releasing

it from the previous attach-

ment point.

Using the chainsaw in the tree

An analysis of accidents with these saws during

tree service operations shows the primary cause

as being inappropriate one-handed use of the

saw. In the vast majority of accidents, operators

fail to adopt a secure work position witch allows

them to hold both handles of the saw.

This results in an increased risk of injury due to:

• not having a firm grip on the saw if it kicks

back;

• a lack of control of the saw such that it is

more liable to contact climbing lines and

operators body (particularly the left hand and

arm)

• losing control from insecure work position

resulting in contact with the saw (unexpected

movement during operation of the saw)

EN 4

1. For Safe Operation

(A)

Securing the work position for two-handed

use

To allow the operator to hold the saw with both

hands, they should as general rule, aim for

secure work position where they are operating

the saw at:

• hip level when cutting horizontal sections;

• solar plexus level when cutting vertical sec-

tions.

Where the operator is working close into vertical

stems with a low lateral forces on their work

position, then a good footing may be all that is

needed to maintain a secure work position.

However as operators

move away from the

stem, they will need to

take steps to remove or

counteract the increasing

lateral forces by, for

example, a re-direct of

the main line via a sup-

plementary anchor point

or using an adjustable

strop direct from the har-

ness to a supplementary

anchor point.

Gaining a good footing at

the working position can

be assisted by use of a

temporary foot stirrup

created from an endless

sling.

Starting the saw in the tree

When starting the saw in the tree, the operator

should:

a) apply the chain brake before starting;

b) hold saw on either the left or right of the

body when starting:

1) on the left side hold the saw with either the

left hand on the front handle or the right hand

on the rear handle and thrust the saw away

from the body while holding the pull starter

cord in the other hand;

2) on the right side, hold the saw with the right

hand on either handle and thrust the saw

away from the body while holding the pull

starter cord in the left hand.

The chain brake should always be engaged

before lowering a running saw onto its strop.

Operators should always check the saw has suf-

ficient fuel before undertaking critical cuts.

One-hand use of the chainsaw

Operators should not use tree service chainsaws

onehanded in place of unstable work positioning

or in preference to a handsaw when cutting small

diameter wood at the branch tips.

Tree service chainsaws should only be used

one-handed where:

• the operator cannot

gain a work posi-

tion enabling two-

handed use; and

• they need to sup-

port their working

position with one

hand; and

• the saw is being

used at full stretch,

at right angles to

and out of line with the operator’s body.

Operators should never:

• cut with the kickback zone at the tip of the

chainsaw guide bar

• ‘hold and cut’ sections

• attempt to catch falling sections.

Freeing a trapped saw

If the saw should become trapped during cut-

ting, operators should:

• switch off the saw and attach it securely to the

tree inboard (i.e. towards the truck side) of the

cut or to a separate tool line;

• pull the saw from the kerf whilst lifting the

branch as necessary;

• if necessary, use a handsaw or second chain

saw to release the trapped saw by cutting a

minimum of 30 cm away from the trapped

saw.

Whether a handsaw or a chainsaw is used to free

a stuck saw, the release cuts should always be

outboard (toward the tips of the branch), in order

to prevent the saw being taken with the section

and further complicating the situation.

3. Installing Guide Bar and Saw Chain EN 7

A standard saw unit package contains the items

as illustrated.

Open the box and install the guide bar and the

saw chain on the power unit as follows:

The saw chain has very

sharp edges. Use thick protective gloves for

safety.

1. Pull the guard towards the front handle to

check that the chain brake is not engaged.

2. Loosen the nuts and remove the chain cover.

3. Fix the hanger on the rear of power unit by

screw.

4. Mount the guide bar then fit the saw chain

around the bar and sprocket.



WARNING!

Pay attention to the correct

direction of the saw chain.

5. Fit the chain tensioner nut into the lower hole

of the guide bar, then install the chain cover,

and fasten the mounting nut to finger tight-

ness.

When installing the

chain cover, be

sure to fit the hook

completely at the

rear end of the

cover.

6. While holding up the tip of the bar, adjust the

chain tension by turning the tensioner screw

until the tie straps just touch the bottom side

of the bar rail.

7. Tighten the nuts securely with the bar tip held

up (12 ~ 15 Nm). Then check the chain for

smooth rotation and proper tension while

moving it by hand. If necessary, readjust with

the chain cover loose.

8. Tighten the tensioner screw.

A new chain will expand its

length in the beginning of use. Check and read-

just the tension frequently as a loose chain can

easily derail or cause rapid wear of itself and the

guide bar.

EN 8 4. Fuel and Chain Oil

• FUEL

Gasoline is very flamma-

ble. Avoid smoking or bringing any flame or

sparks near fuel.

Make sure to stop the engine and allow it cool

before refueling the unit.

Select outdoor bare ground for fueling and

move at least 3 m (10 ft) away from the fuel-

ing point before starting the engine.

• The engines are lubricated by oil specially for-

mulated for air-cooled 2-cycle gasoline engine

use. Use an anti-oxidant added quality oil

expressly labeled for air-cooled 2-cycle engine

use (JASO FC GRADE OIL or ISO EGC

GRADE).

• Do not use BIA or TCW (2-stroke water-cool-

ing type) mixed oil.

• RECOMMENDED MIXING RATIO GASO-

LINE 50: OIL 1

• Exhaust emission are controlled by the funda-

mental engine parameters and components

(eq., carburation, ignition timing and port tim-

ing) without addition of any major hardware or

the introduction of an inert material during

combustion.

• These engines are certified to operate on

unleaded gasoline.

• Make sure to use gasoline with a minimum

octane number of 89RON (USA/Canada:

87AL).

• If you use a gasoline of a lower octane value



WARNING!

than prescribed, there is a danger that the

engine temperature may rise and an engine

problem such as piston seizing may conse-

quently occur.

• Unleaded gasoline is recommended to reduce

the contamination of the air for the sake of

your health and the environment.

• Poor quality gasolines or oils may damage

sealing rings, fuel lines or fuel tank of the

engine.

• HOW TO MIX FUEL

Pay attention to agitation.

1. Measure out the quantities of gasoline and oil

to be mixed.

2. Put some of the gasoline into a clean,

approved fuel container.

3. Pour in all of the oil and agitate well.

4. Pour in the rest of gasoline and agitate again

for at least one minute. As some oils may be

difficult to agitate depending on oil ingredi-

ents, sufficient agitation is necessary for the

engine to last long. Be careful that, if the agi-

tation is insufficient, there is an increased

danger of early piston seizing due to abnor-

mally lean mixture.

5. Put a clear indication on the outside of the

container to avoid mixing up with gasoline or

other containers.

6. Indicate the contents on outside of container

for easy identification.

• FUELING THE UNIT

1. Untwist and remove the fuel cap. Rest the

cap on a dustless place..

2. Put fuel into the fuel tank to 80% of the full

capacity.

3. Fasten the fuel cap securely and wipe up any

fuel spillage around the unit.



WARNING!

4. Fuel and Chain Oil

4. Fuel and Chain Oil EN 9

1. Select flat and bare ground for fueling.

2. Move at least 10 feet (3 meters) away from

the fueling point before starting the

engine.

3. Stop the engine before refueling the unit.

At that time, be sure to sufficiently agitate

the mixed gasoline in the container.

• FOR YOUR ENGINE LIFE, AVOID:

1. FUEL WITH NO OIL (RAW GASOLINE) – It will

cause severe damage to the internal engine

parts very quickly.

2. GASOHOL – It can cause deterioration of

rubber and/or plastic parts and disruption of

engine lubrication.

3. OIL FOR 4-CYCLE ENGINE USE – It can

cause spark plug fouling, exhaust port block-

ing, or piston ring sticking.

Mixed fuels which have been left unused

for a period of one month or more may clog

the carburetor and result in the engine failing

to operate properly.

5. In the case of storing the product for a long

period of time, clean the fuel tank after ren-

dering it empty. Next, activate the engine and

empty the carburetor of the composite fuel.

6. In the case of scrapping the used mixed oil

container, scrap it only at an authorized

repository site.

Moreover, normal wear and

change in product with no functional influence

are not covered by the warranty. Also, be careful

that, if the usage in the instruction manual is not

observed as to the mixed gasoline, etc.

described therein, it may not be covered by the

warranty.

• CHAIN OIL

Only use special oil for chain

saws or adhesive oil for chain saws. Do not use

oil containing impurities so as not to block the oil

filter and to prevent irreparable damage to the oil

pump.

The special oil for lubricating

the chain is biodegradable. Use of a mineral oil

or engine oil causes serious damage to the envi-

ronment.

IMPORTANT

NOTE



WARNING!

It is essential that you use good quality oil to

lubricate the cutting parts effectively. Used or

poor quality oil does not guarantee good lubri-

cation and reduces the duration of the chain and

bar.

It is always worth topping up the oil tank com-

pletely (using a funnel) every time you refuel.

Since the oil tank capacity is enough to guaran-

tee that the fuel runs out first, you will avoid the

risk of operating the machine without lubricant.

EN 10 5. Operating the Engine

It is very dangerous to run

a chainsaw that mounts broken parts or lacks

any parts. Before starting engine, make sure

that all the parts including bar and chain are

installed properly.

•STARTING THE ENGINE

• Before starting the engine

1. Fill fuel and chain oil tanks respectively, and

tighten the caps securely.

2. Continuously push the priming bulb until fuel

comes in the bulb.

3. Set the switch to “I” position.

4. Pull out the choke knob to the second-stage

position. The choke will close and the throttle

lever will then be set in the starting position.

When restarting immediately

after stopping the engine, set the Choke knob in

NOTE



WARNING!

the first-stage position (choke open and throttle

lever in the starting position).

Once the choke knob has

been pulled out, it will not return to the operating

position even if you press down on it with your

finger. When you wish to return the choke knob

to the operating position, pull out the throttle

lever instead.

Before you start the

engine, make sure the saw chain is not con-

tacting anything.

• Starting the engine on the ground

Do not start the engine

while the chain saw hangs in one hand. The

saw chain may touch your body. This in very

dangerous.

Keep clear of the saw

chain as it will start rotating upon starting of

engine.

5. While holding the saw unit securely on the

ground, pull the starter rope vigorously.

6. When engine has ignited, first push in the

choke knob to the first-stage position and

then pull the starter again to start the engine.

7. Allow the engine to warm up with the throttle

lever pulled slightly.

• Starting the engine on a tree

Carefully follow the

instructions under “For your safety” (1.2).

• CHECKING THE OIL SUPPLY

Make sure to set up the bar

and the chain when checking the oil supply.

If not, the rotating parts may be exposed. It is

very dangerous.

After starting the engine, run the chain at medi-

um speed and see if chain oil is scattered off as

shown in the figure.

The chain oil flow can be changed by inserting a

screwdriver in the hole on bottom of the clutch

side. Adjust according to your work conditions.

The oil tank should become

nearly empty by the time fuel is used up. Be sure

to refill the oil tank every time when refueling the

saw.

• ADJUSTING THE CARBURETOR

The carburetor on your unit has been factory

adjusted, but may require fine tuning due to a

change in operating conditions.

Before adjusting the carburetor, make sure that

the provided air/fuel filters are clean and fresh

and the fuel properly mixed.

NOTE



WARNING!



WARNING!

When adjusting, take the following steps:

Be sure to adjust the carbu-

retor with the bar chain attached.

1. “H” and “L” needles are restricted within the

number of turn as shown below.

“H” needle: -1/4

“L” needle: -1/4

2. Start the engine and allow it to warm up in

low speed for a few minutes.

3. Turn the idle adjusting screw (T) counter-

clockwise so that the saw chain does not

turn. If the idling speed is too slow, turn the

screw clockwise.

4. Make a test cut and adjust the “H” needle for

best cutting power, not for maximum speed.

• CHAIN BRAKE

The chain brake is a device which stops the

chain instantaneously if the chain saw recoils

due to kickback.

Normally, the brake is activated automatically by

inertial force. It can also be activated manually

by pushing the brake lever (left-hand guard)

down toward the front.

When the brake operates, a yellow cone pops up

from the base of the brake lever.

Releasing the Brake

Pull the brake lever up toward the left-hand han-

dle until it clicks into place.

When the brake operates,

release the throttle lever to slow down the

engine speed. Continuous operation with the

brake engaged will generate heat from the

6. Sawing EN 13

• Before proceeding to

your job, read the sec-

tion “For Safe Oper-

ation”. It is recommend-

ed to first practice saw-

ing easy logs. This also

helps you get accus-

tomed to your unit.

•Always follow the safety

regulations. The chain

saw must only be used

for cutting wood. It is

forbidden to cut other

types of material.

Vibrations and kickback

vary with different mate-

rials and the require-

ments of the safety reg-

ulations would not be

respected. Do not use

the chain saw as a lever

for lifting, moving or

splitting objects. Do not

lock it over fixed stands.

It is forbidden to hitch

tools or applications to

the PTO other than

those specified by the

manufacturer.

•

It is not necessary to force the saw into the

cut. Apply only light pressure while running the

engine at full throttle.

• When the saw chain is caught in the cut, do

not attempt to pull it out by force, but use a

wedge or a lever to open the way.

• GUARD AGAINST KICKBACK



WARNING!

•

This saw is equipped with

a chain brake that will

stop the chain in the

event of kickback if oper-

ating properly. You must

check the chain brake

operation before each

usage by running the saw

at full the throttle for 1-2

seconds and pushing the

front hand guard forward.

The chain should stop

immediately with the

engine at full speed. If the

chain is slow to stop or

does not stop, replace the

brake band and clutch

drum before use.

• It is extremely important

that the chain brake be

checked for proper oper-

ation before each use and

that the chain be sharp in

order to maintain the kick-

back safety level of this

saw. Removal of the safe-

ty devices, inadequate

maintenance, or incorrect

replacement of the bar or

chain may increase the

risk to serious personal

injury due to kickback.

• FELLING A TREE

1. Decide the felling direction considering the

wind, lean of the tree, location of heavy

branches, ease of completing the task after

felling and other factors.

2. While clearing the area around the tree,

arrange a good foothold and retreat path.

(1) Notch cut

(2) Felling cut

(3) Felling direction

6. Sawing

EN 14 6. Sawing

3. Make a notch cut one-third of the way into

the tree on the felling side.

4. Make a felling cut from the opposite side of

the notch and at a level slightly higher than

the bottom of the notch.

When you fell a tree, be

sure to warn neighboring workers of the dan-

ger.

Bucking and Limbing

•Always ensure your foothold. Do not stand

on the log.

• Be alert to the rolling over of a cut log.

Especially when working on a slope, stand

on the uphill side of the log.

• Follow the instructions in “For Safe

Operation” to avoid kickback of the saw.

Before starting work, check the direction of

bending force inside the log to be cut. Always

finish cutting from the opposite side of the bend-

ing direction to prevent the guide bar from being

caught in the cut.

A log lying on the ground

Saw down halfway, then roll the log over and cut

from the opposite side.

A log hanging off the ground

In area “A”, saw up from the bottom one-third

and finish by sawing down from the top. In area

“B”, saw down from the top one-third and finish

by sawing up from the bottom.

1. Saw Chain

It is very important for

smooth and safe operation to always keep

the cutters sharp.

The cutters need to be sharpened when:

• Sawdust becomes powder-like.

•You need extra force to saw in.

• The cut path does not go straight.

•Vibration increases.

• Fuel consumption increases.

Cutter setting standards

Be sure to wear safety

gloves.

Before filing:

• Make sure the saw chain is held securely.

• Make sure the engine is stopped.

• Use a round file of proper size for the chain

(5/32 in. - 4.0 mm).

Place the file on the cutter and push straight for-

ward.

Keep the file position as illustrated.

After each cutter has been filed, check the depth

gauge and file it to the proper level as illustrated.

Be sure to round off the

front edge to reduce the chance of kickback

or tie-strap breakage.

2. Guide Bar

• Reverse the bar occasionally to prevent partial

wear.

• The bar rail should always be square.

Check for wear of the bar rail. Apply a ruler to the

bar and the outside of a cutter. If a gap is

observed between them, the rail is normal.

Otherwise, the bar rail is worn. Such a bar needs

to be corrected or replaced.
