Noise Information

Measured sound values determined according to ISO 22868.
The noise figures quoted are emission levels and are not
necessarily safe working levels. Whilst there is a correlation
between the emission and exposure levels, this cannot be used
reliably to determine whether or not further precautions are
required. Factors that influence the actual level of exposure of
work-force include the characteristics of the work room, the other
sources of noise, etc. i.e. the number of machines and other
adjacent processes, and the length of time for which an operator
is exposed to the noise. Also the permissible exposure level can
vary from country. This information, however, will enable the user
of the machine to make a better evaluation of the hazard and risk.

Wear hearing protection

Vibration total values (triax vector sum) determined according to
ISO 22867:

5

The vibration emission level given in this information sheet has
been measured in accordance with a standardized test given in
ISO 22867:2003 and may be used to
compare one tool with another.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main
applications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained, the
vibration emission may differ. This may significantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or when it
is running but not actually doing the job. This may significantly
reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from
the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organization of work patterns.

SPECIAL SAFETY WARNINGS FOR THE TOOL

12

Keep all parts of the body away from the saw chain when the chain saw is

operating.

Before you start the chain saw, make sure the saw chain is not

contacting anything.

A moment of inattention while operating chain saws may cause entanglement

of your clothing or body with the saw chain.

Always hold the chain saw with your right hand on the rear handle and

your left hand on the front handle. Holding the chain saw with a reversed

hand configuration increases the risk of personal injury and should never be

done.

Wear safety glasses and hearing protection. Further protective

equipment for head, hands, legs and feet is recommended. Adequate

protective clothing will reduce personal injury by flying debris or accidental

contact with the saw chain.

Do not operate a chain saw in a tree. Operation of a chain saw while up in a

tree may result in personal injury.

Always keep proper footing and operate the chain saw only when

standing on fixed, secure and level surface. Slippery or unstable surfaces

such as ladders may cause a loss of balance or control of the chain saw.

When cutting a limb that is under tension be alert for spring back. When

the tension in the wood fibres is released the spring loaded limb may strike the

operator and/or throw the chain saw out of control.

Use extreme caution when cutting brush and saplings. The slender

material may catch the saw chain and be whipped toward you or pull you off

balance.

Carry the chain saw by the front handle with the chain saw switched off

and away from your body. When transporting or storing the chain saw

always fit the guide bar cover. Proper handling of the chain saw will reduce

the likelihood of accidental contact with the moving saw chain.

Follow instructions for lubricating, chain tensioning and changing

accessories.

Improperly tensioned or lubricated chain may either break or increase the

chance for kickback.

13

Keep handles dry, clean, and free from oil and grease. Greasy, oily handles

are slippery causing loss of control.

Cut wood only. Do not use chain saw for purposes not intended. For

example: do not use chain saw for cutting plastic, masonry or non-wood

building materials. Use of the chain saw for operations different than intended

could result in a hazardous situation.

KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS

• How to read symbols and colors (Fig. 1)

Fig. 1

Warning: RED Used to warn that an unsafe procedure should not

be performed.

WARNING

1. Avoid bar nose contact

2. Beware of kick back.

3. Do not attempt to hold saw with one hand

4. Hold saw properly with both hands.

DANGER! BEWARE OF KICKBACK!

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, kicking the guide bar up and back towards the operator.

14

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 personal injury.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:

Fig, 2A Fig. 2B

BEWARE OF: ROTATIONAL KICKBACK (Fig. 2A)

A = Kickback path
B = Kickback reaction zone

THE PUSH (PINCH KICKBACK) AND PULL REACTIONS (Fig. 2B)

A = Pull
B = Solid objects
C = Push

Maintain a firm grip, with thumbs and fingers encircling the chain saw

handles, with both hands on the saw and position your body and arm to

allow you to resist kickback forces. Kickback forces can be controlled by the

operator, if proper precautions are taken. Do not let go of the chain saw.

Do not overreach and do not cut above shoulder height. This helps prevent

unintended tip contact and enables better control of the chain saw in

unexpected situations.

Only use replacement bars and chains specified by the manufacturer.

Incorrect replacement bars and chains may cause chain breakage and/or

15

kickback.

Follow the manufacturer’s sharpening and maintenance instructions for

the saw chain. Decreasing the depth gauge height can lead to increased

kickback.

INTENDED USE

The chain saw is intended for sawing of trees, tree trunks,
branches, wooden beams, planks, etc. Cuts can be sawed with or
across the grain. This product is not suitable for sawing mineral
materials.

ASSEMBLY

WARNING!

Always carry out a test run before starting work and after every
tool change! Always ensure that the tools are in good condition,
correctly mounted and able to turn freely. The trial run should be
at last 30 sec.

Adjusting chain tension

WARNING!

The saw chain has very sharp edges. Use protective gloves for
safety.

Saw chain tensioning

1) Always check the saw chain tension before use, after the first cuts and

regularly during use, approx. every five cuts. Upon initial operation, new

chains can lengthen considerably. This is normal during the break-in period

and the interval between future adjustments will lengthen quickly.

2) Lift up the tip of the guide bar (13) and keep it there as you adjust the

18

tension (Fig. 10).

Fig. 10

3) Turn the tension screw (22a) until the chain ‘tie straps’ are just touching the

bottom edge of the guide bar (13) (Fig. 11, 12).

Fig. 11 Fig. 12

4) Lift up the tip of the guide bar (13) and tighten the rear retaining nut (16)

first followed by the front retaining nut (16) (Fig. 9).

5) By hand, pull the saw chain (14) along the top of the guide bar (13) from

one end to the other, several times. The chain should feel tight but still

move freely.

Tension test

Check the chain tension using one hand to lift the saw chain (14) against the

weight of the product. The correct chain tension is achieved when the saw

chain can be lifted by approximately 2 - 4 mm from the guide bar (13) in the

centre (Fig. 13, 14).

22a

19

Fig. 13 Fig. 14

Adjust the tension if you find that the chain saw is too loose or tight.

WARNING!

Do not over tension the chain as this will lead to excessive wear
and will reduce the life of bar and chain. Over tensioning also
reduce the amount of cuts you should get.

OPERATION

Before use

Please always read the instruction manual carefully and check the machine

before operating.

WARNING!

Ensure that the engine has oil. When leaving the factory. This
machine has NO OIL in the engine.
Check the saw chain, never use chain that are dull, cracked or
damaged.
Make sure the handle and safety features are in good working
order. Never use a machine that lacks a part or has been modified
outside its specifications.
The enclosures must be correctly fitted and undamaged before
you start the machine.

WARNING!

Please always use quality gloves, foot, ear and eye protector.
They should with CE mark and tested according to PPE (Person
Protective Equipment) directive.
The poor equipments may reduce the protection and result in
person injure during working.

Engine fuel

WARNING!

The chain saw is fitted with a two-stroke engine; use fuel

20

mixed with oil only.

Only fuel the machine in well-lit areas. Avoid fuel spillage. Never refuel the

machine during operation. Let the engine cool down for about two minutes

before refueling.

Refueling must not be carried out near naked flames, control lamps or spark

producing electrical equipment such as electric tools, welders or sanders.

1. Make sure the machine is turned off, by turn the ignition switch to the “off”

position.

2. Check the fuel by a visual check , remove the fuel tank cap and reviewing

the fuel level.

3. Full unleaded fuel mixed with oil from an approved fuel container into the

fuel tank, because of fuel expands, please fill the tank to the neck of tank

only.

4. Turn the fuel cap clockwise to assembly it in position.

WARNING.

 Do not refill fuel while engine is running or hot.

 Make sure fuel is not leaking.

Use quality two-stroke oil and make a mixture of 40 parts petrol to one

part oil only (2,5% oil mixed in fuel).

Never use two-stroke oil intended for water-cooled engines.
Never use oil intended for four-stroke engines.
A poor oil quality and/or too high oil/fuel ratio may jeopardize
function and decrease the life time of catalytic converters.
Shake the container well to obtain a correct mixture before filling
the tank.

21

Use at least 90 octane fuel. We recommend unleaded petrol as it
leaves fewer residues inside the motor and on the ignition plug,
and prolongs the life cycle of the exhaust system. Never use old
or dirty petrol or oil/petrol mixtures. Avoid contamination with dirt
or water in the tank. Occasionally ignition knocking or clanging
can be heard with high loads. This is normal and no cause for
alarm. If ignition knocking or clanging occurs during normal loads
and with constant motor speed you should change the petrol
quality. If this does not solve the problem contact an authorized
specialist dealer.
When working at continuous high revs a higher octane rating is
recommended.

Chain Oil

Use special chain saw oil all year round.
Only oil the saw chain in well-lit areas. Avoid spillage. Never oil
the machine during operation. Let the engine cool down for about
two minutes before refilling oil.
Oil must not be carried out near naked flames, control lamps or
spark producing electrical equipment such as electric tools,
welders or sanders.

1. Make sure the machine is turned off, by turn the ignition switch to the “off”

position.

2. Check the oil by a visual check , remove the chain oil tank cap(28) and

reviewing the oil level.

3. Full oil into oil tank, because of oil expands, please fill the tank to the neck

of tank only.

4. Turn the chain oil tank cap(28) clockwise to assembly it in position.

5. Check the chain lubrication before each use.

6. Make sure the guide bar (13) and the saw chain (14) are in place when you

check the oil delivery.

7. Start the engine; keep it running at medium power and check if the chain oil

is delivered as shown in the figure (Fig. 15).

8. Adjust the chain oil flow using screwdriver (33) on the adjuster screw (Fig.

22

16, a) of the oiler, which is on the bottom of the product.

Fig. 15 Fig. 16

WARNING.

a) Do not refill oil while engine is running or hot.
b) Make sure oil is not leaking.

Caution!

Do not use waste or regenerated oil that can cause damage to the
oil pump.

Caution!

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.

Check the air filter

Check the air filter to be sure it is clean and in good condition.
Loosen the air cleaner cover screw, and remove the air filter
cover, then check the main air filter. Clean or replace the air filter
if necessary.

Starting the engine

WARNING!

The cutting attachement may start to move when the engine
is started. Make sure the attachment can not come into
contact with any object.

23

Make sure that no unauthorised persons are in the working
area, otherwise there is a risk of serious personal injury.

1. Press the primer (4) several times until fuel begins to fill the bulb.

2. Turn the ignition switch (27) to the” ON “position.

3. To start a cold engine, Pull out the choke knob (5) to the start position.

4. During start the engine, the throttle trigger need not locked in idling position.

Don’t touch it during starting.

5. Slowly pull the starter handle until you feel it engage and then pull it

quickly. Return the starter handle gently and slowly to the original position

by hand.

Note: when the engine is started for the very first time. It will require a

number of attempts to start until the fuel has travelled from the tank to

the motor.

6. Push the choke knob to the run positon as the engine started.

7. After starting the engine, let the engine run for 2 to 3 minutes so that it

warms up before subjecting it to any load.

Under the following conditions the machine must be stop:

1. When the motor rotary speed changes

2. When sparks occur

3. When saw chain are damaged

4. In case of misfire

5. In case of high vibration

6. When flames or smoke appear

24

7. In rain or stormy weather

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 (Front
handle guard) down toward the front.

To release brake, pull up the front handle guard toward the front
handle till “click” sound is heard.

WARNING!

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 clutch and may cause trouble.
Be sure to check brake operation on the daily inspection.

How to confirm:

1) Turn off the engine.

2) Holding the chain saw horizontally, remove your hand from the front handle,

and let the tip of the guide bar hit a stump or a piece of wood, and check the

brake is operating. Operating level varies by bar size.

In case the brake is not effective, ask our dealer inspection and repairing.

Sawing

During cutting, please don’t keep the running speed just above

clutch engagement speed. Any prolonged use at low speed is
likely to cause premature wear of the clutch.
On the other hand, the user should not keep the engine speed in
max speed after cutting. Any prolonged use at the highest speed
is likely to reduce lifetime of engine.
Always take care to maintain a well balanced and secure position.

CAUTION!

In an emergency, stop the engine by moving the engine switch to

25

the stop position.
If the saw chain strikes stone or other debris, stop the engine and
check whether something has been damaged and the saw chain
is still secure.

WARNING!

Before proceeding to your job, read "For Safe Operation" section
It is recommended to first practice sawing easy logs. This also
helps you get accustomed 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 materials and the
requirements of the safety regulations 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 not necessary to force the saw into the cut. Apply only light
pressure while running the engine at full throttle.
Racing the engine with the chain seized in a cutaway can damage
the clutch system. 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 cut.
When cutting trees and thick branches, the teeth of the spiked
bumper can be tied to the wood, prevent slippery, and easy
cutting under the focal point.

Safe chainsaw operation

BB.101 Felling a tree

When bucking and felling operations are being performed by two
or more persons at the same time, the felling operations should
be separated from the bucking operation by a distance of at least
twice the height of the tree being felled. Trees should not be felled
in a manner that would endanger any person, strike any utility line
or cause any property damage. If the tree does make contact with
any utility line, the company should be notified immediately.

26

The chain saw operator should keep on the uphill side of the
terrain as the tree is likely to roll or slide downhill after it is felled.
An escape path should be planned and cleared as necessary
before cuts are started. The escape path should extend back and
diagonally to the rear of the expected line of fall as illustrated in
Figure BB.101.
Before felling is started, consider the natural lean of the tree, the
location of larger branches and the wind direction to judge which
way the tree will fall.
Remove dirt, stones, loose bark, nails, staples and wire from the
tree.

BB.102 Notching undercut

Make the notch 1/3 the diameter of the tree, perpendicular to the
direction of falls as illustrated in Figure BB.102. Make the lower
horizontal notching cut first. This will help to avoid pinching either
the saw chain or the guide bar when the second notch is being
made.

BB.103 Felling back cut

Make the felling back cut at least 50 mm higher than the
horizontal notching cut as illustrated in Figure BB.102. Keep the
felling back cut parallel to the horizontal notching cut. Make the
felling back cut so enough wood is left to act as a hinge. The
hinge wood keeps the tree from twisting and falling in the wrong
direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree should begin to fall.
If there is any chance that the tree may not fall in desired direction
or it may rock back and bind the saw chain, stop cutting before
the felling back cut is complete and use wedges of wood, plastic
or aluminium to open the cut and drop the tree along the desired
line of fall.
When the tree begins to fall remove the chain saw from the cut,
stop the motor, put the chain saw down, then use the retreat path

27

planned. Be alert for overhead limbs falling and watch your
footing.

BB.104 Limbing a tree

Limbing is removing the branches from a fallen tree. When
limbing leave larger lower limbs to support the log off the ground.
Remove the small limbs in one cut as illustrated in
Figure BB.103. Branches under tension should be cut from the
bottom up to avoid binding the chain saw.

BB.105 Bucking a log

Bucking is cutting a log into lengths. It is important to make sure
your footing is firm and your weight is evenly distributed on both
feet. When possible, the log should be raised and supported by
the use of limbs, logs or chocks. Follow the simple directions for
easy cutting
When the log is supported along its entire length as illustrated in
Figure BB.104, it is cut from the top (overbuck).
When the log is supported on one end, as illustrated in Figure
BB.105, cut 1/3 the diameter from the underside (underbuck).
Then make the finished cut by overbucking to meet the first cut.
When the log is supported on both ends, as illustrated in Figure
BB.106, cut 1/3 the diameter from the top (overbuck). Then make
the finished cut by underbucking the lower 2/3 to meet the first
cut.
When bucking on a slope always stand on the uphill side of the
log, as illustrated in Figure

BB.107. When “cutting through”, to maintain complete control

release the cutting pressure near the end of the cut without

relaxing your grip on the chain saw handles. Don’t let the chain

contact the ground. After completing the cut, wait for the saw
chain to stop before you move the chain saw. Always stop the
motor before moving from tree to tree.

Cleaning air filter

1. Loosen the air filter cover screw and remove the air filter cover.

2. Loose the screws fixing the dirty air filter and remove it.

3. Clean the air filter in solvent.

4. Place the filter in dry place to remove excess solvent.

34

5. Reinstall the air filters and screws.

6. Reinstall the air filter cover, and tighten the air filter cover screw.

WARNING:

The use of petrol or combustible solvents for cleaning can cause
fire or explosion. Therefore only use soap water or
non-combustible solvent. Never operate the machine without the
air filter.

Caution!

A used air filter can never be completely cleaned．It is advisable
to replace your air filter with a new one after every 100 hours of
operation, or 6 months, whichever comes first

Changing air filter

1. Loosen the air filter cover screw and remove the air filter cover.

2. Loose the screws fixing the dirty air filter and remove it.

3. Reinstall the new air filters and screws.

4. Reinstall the air filter cover, and tighten the air filter cover screw.

Spark plug

To ensure proper engine operation, the spark plug must be properly gapped and

free of deposits.

1. Remove the spark plug cover from the housing.

2. Remove the spark plug cap.

3. Clean any dirt from around the spark plug base.

4. Use the socket spanner which provided to remove the spark plug.

5. Visually inspect the spark plug. Remove carbon deposits using a wire brush.

6. Check for discoloration on the top of the spark plug. The standard color

should be a tan color.

7. Check the spark plug gap. The acceptable gap should be between

0,6-0,7mm.

35

8. Install /reinstall the spark plug carefully by hand.

9. Once the spark plug has been seated, tighten it with a spark plug wrench.

10. Reinstall the spark plug cap on top of the spark plug.

11. Reinstall the spark plug cover.

Cleaning

Warning: cutting edges of chain are sharp, use protective
gloves when handling chain.

1. Keep your machine clean, the outside of the machine can be cleaned using

a damp soft cloth with a mild detergent if required, never use water to clean

the machine as it may cause damage to internal parts.

2. Some maintenance products and solvents may damage the plastic parts,

these include products containing benzene, trichloroethylene, chloride or

ammonia.

3. Take special care to keep the ventilation inlets /outlets free from

obstruction. Cleaning with a soft brush followed by a compressed air jet will

usually be sufficient to ensure acceptable internal cleanliness.

4. Wear eye protection when carrying out cleaning.

Care of guide bar

Uneven bar wear causes most guide bar problems, incorrect
sharpening of chain cutter and depth gauge settings often cause
this, when bar wears unevenly, it widens guide bar groove, this
causes chain clatter ad river popping. Saw will not cut straight,
replaces guide bar if this occurs.
Inspect guide bar before sharpening chain. A worn or damaged
guide bar is unsafe. A worn or damaged guide bar will damage
chain, it will also make cutting harder.

36

Normal guide bar maintenance

1. Remove guide bar from chain saw.

2. Remove sawdust from guide bar groove periodically. Use putty knife or wire,

3. Clean oil slots after each day of use.

4. Remove burrs from sides of guide bar. Use flat file to make side edges square.

Replace guide bar when

- bar is bent or cracked.

- Inside groove of bar is badly worn .

Chain sharpening

Warning ! always wear gloves while handling the chain

The chain requires sharpening when the chain saw does not cut
appropriately. This operation is performed as follows :

1. Extend the chain bar.

2. Fix the bar in a vice so that the chain can slide.

3. Place the file over the tooth at 35º

4. File forward only until all the worn part of the tooth has been eliminated.

5. count the file movements made on the first tooth and do the same on all

37

the others, both right and left ,

6. After some sharpening the delimiting device on the chain will exceed the

height of the cutting teeth, file the exceeding part by means of a flat file to

round off the depth delimiting device.

7. Ensure that the chain is replaced before stretching to exceed the maximum

adjustment of the chain saw bar.

8. ‘Deep’ Filing should be performed with an

electric file, we advise to use a

repair service or a similarly qualified specialist to perform this operation.

9. Ensure that the chain slides smoothly over the bar when pulled with hands,

periodically sharpen chain and check the chain tension.

10. Bars with sprockets need frequent greasing which can be performed as

follows :

- Fill a syringe or similar device with grease for bearings.

- Each time the saw is used grease through the hole provided near the

bar tip until the grease penetrated onto the tip.

- After 3 times of sharpening the chain your self have it professionally

sharpened, this will ensure that all the teeth are even.

To avoid damage to the motor, do not keep the chain saw running if the chain is

lodged in the wood.

Empty the fuel / oil

1. Place the machine on even and stable surface. Warm up the engine for

several minutes and then stop it.

2. Loosen the fuel / oil tank cover and remove it.

3. Drain fuel / oil into a container thoroughly.

4. Press the intake pump several times until fuel begins to empty the bulb.

5. Drain fuel / oil again.

6. Reinstall the fuel / oil tank cover.

38

REPAIRS

The machine can only be repaired by

a repair service or a

similarly qualified specialist.
