Rules for safe operation

1. General precautions

Operator's manual

Read the operator's manual for your chain saw carefully.

Be thoroughly familiar with the chain saw's controls and how to use the chain saw properly.

Failure to follow instructions could lead to personal injury.

If you have any questions or problems, please contact your shindaiwa dealer.

Physical condition

Do not operate a chain saw when you are fatigued or under the influence of alcohol or

drugs.

You should be in good physical and mental health in order to handle your chain saw safely.

Errors in judgement or execution can be serious or fatal.

If you have any physical condition which strenuous work could worsen, check with your phy-

sician before using a chain saw.

Do not operate when ill or fatigued, or under the influence of any substance or medication

which could affect your vision, dexterity or judgement.

The ignition system of this product generates electromagnetic fields during operation.

Magnetic fields can cause pacemaker interference or pacemaker failure.

To reduce health risks, we recommend that pacemaker users consult their physician and

the pacemaker manufacturer before operating this product.

Personal equipment

Always wear approved goggles to protect your eyes.

Wood chips, dust, snapping branches and other debris can be thrown by the cutting chain

into the operator's facial area.

Goggles may also offer limited protection in the event of the cutting chain hitting the oper-

ator in the eye area.

If conditions warrant that a ventilated face shield be worn, goggles must be worn under-

neath it.

shindaiwa advises wearing hearing protection at all times.

If not followed, hearing loss can occur.

You should reduce the risk of hearing damage by wearing either "headset" type protectors

or ear plugs which are approved by an authorized organization.

All persons who make part of their living using chain saws should be tested periodically

for hearing deterioration.

Always wear a helmet when working with a chain saw.

A safety hard helmet is highly recommended when felling or working under trees, or when

objects can fall on you.

Wear heavy duty, non-slip gloves for improved grip, and also for protection against cold

and vibration.

Safety tip shoes or boots with non-slip sole should be worn.

Never wear loose clothing, unbuttoned jackets, flared sleeves and cuffs, scarves, tie-

strings, neckties, cords, chains, jewellery, etc. which could snag the saw chain or under-

brush.

Clothing should be of sturdy, protective material.

It should be snug-fitting to resist snagging, but roomy enough for freedom of movement.

Trouser legs should not be flared or cuffed, and should be either tucked into the boot tops

or trimmed short.

Safety vests, leg chaps and logger's pants of ballistic material are available.

It is the operator's responsibility to wear such additional protection if conditions warrant it.

Never operate a chain saw when you are alone.

Arrange to have someone remain within calling distance in case you need help.

CAUTION

Stuffing ears with cotton is not recommended.

6

Fuel

1. Oil tank cap

2. Fuel tank cap

A: Loosening direction

B: Tightening direction

Use an appropriate type of fuel container.

Bring an extinguisher or shovel in case of fire.

Despite the precautions which can be taken, operating a chain saw, or just working in the

forest, presents dangers.

Do not smoke or bring flame or sparks near to fuel supplies.

The fuel tank may be under pressure.

Always loosen the fuel cap and wait for pressure to be equalized before removing the cap.

When fuel tank cap or oil tank cap is difficult to remove by fingers, make sure that the

ignition switch is off, and put the starter handle into the groove of cap and turn it anti-

clockwise.

Fill the fuel tank outdoors over bare ground and install the fuel cap securely.

Do not pour fuel indoors.

Wipe any spilled fuel off the unit.

Never refuel while the engine is still hot, or fuel a running engine.

Do not store the unit with fuel in its tank, because a fuel leak could start a fire.

Always fill up the chain oil first, then fill up the fuel mixture.

DANGER

Petrol and fuel are extremely flammable.

If spilled or ignited by ignition source, it can cause fire and serious injury or prop-

erty damage.

Extreme caution is required when handling petrol or fuel.

After refuelling, tighten fuel cap firmly and check for leakage.

In case of fuel leakage, repair before starting operation since there is a danger of

fire.

7

Starting engine

Move the chain saw at least 3 m from the fuelling point before starting the engine.

Do not allow other persons to be near the chain saw when you are starting or cutting with

the chain saw.

Keep bystanders and animals out of the work area.

Do not let anyone hold wood for you to cut.

Do not start cutting until you have a clear work area, secure footing and a planned retreat

path from the falling tree.

Before you start the engine, make sure that the saw chain is not contacting anything.

Keep the handles dry, clean, and free of oil or fuel mixture.

Operate the chain saw only in well-ventilated areas.

Exhaust gas, oil mist (from chain saw lubrication) or saw dust is harmful to health.

Transportation

1. Guide bar cover

When transporting your chain saw, use the appropriate guide bar cover.

Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and

the silencer away from your body.

Transport and storage

Always keep the engine shut off and make it certain that cutting device is securely cov-

ered. When transporting the machine, properly secure it to prevent flipping over, fuel

spillage and damage to the unit.

8

2. Kickback safety precautions

1. High kickback

In some cases, tip contact may cause a lightning-fast reverse reaction, kicking the guide

bar up and back toward the operator (this is called a rotational kickback).

Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back

toward the operator (this is called a linear kickback).

Either or these reactions may cause you to lose control of the saw and come in contact

with the moving chain, which could result in serious personal injury.

As a chain saw user, you should take several steps to keep your cutting jobs free from ac-

cident or injury.

With a basic understanding of kickback, you can reduce or eliminate the element of sur-

prise.

Sudden surprise contributes to accidents.

Understand that rotational kickback is preventable by keeping an unshielded bar nose from

touching an object or the ground.

Do not operate a chain saw with one hand!

Serious injury to the operator, helpers or bystanders may result from one-handed operation.

For proper control, always use two hands when operating a chain saw, one of which oper-

ates the trigger.

Otherwise, this can result in the chain saw "skating" or skidding, which can result in person-

al injury due to loss of control.

Be alert for the phenomena "skating" and "bouncing", greater risk from kickback.

Be cautious not to lose balance of your body due to "drop" at the end of a cut.

Keep a good firm grip on the saw which both hands, with the right hand on the rear han-

dle 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.

Two hands must be used to control the saw at all times.

Do not overreach or cut above chest height.

Make sure that the area in which you are cutting is free from obstructions.

Do not let the bar nose contact a log, branch, or any other obstruction which could be hit

while you are operating the saw.

Cutting at high engine speeds may reduce the likelihood of kickback.

But cutting at part-throttle or low engine speeds may be preferable to control the chain saw

in tight situations and may also reduce the likelihood of kickback.

Follow manufacturer's sharpening and maintenance instructions for the saw chain.

Use only replacement guide bars and chains specified by the manufacturer, or the ac-

ceptable equivalents of these guide bars and chains.

DANGER

Kickback safety precaution 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.

3. Other safety precautions

Vibration and cold

It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of cer-

tain individuals, may be brought about by exposure to cold and vibration.

Accordingly, your shindaiwa chain saw has an anti-vibration device designed to reduce the

intensity of vibration received through the handles.

Exposure to cold and vibration may cause tingling and burning followed by loss of colour and

numbness in the fingers. (White finger syndrome)

We strongly recommend you take the following precautions 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 breaks and also by not smoking.

Limit the number of hours of chain saw operation.

Try to fill a part of each work day with jobs other than chain sawing.

If you experience discomfort, redness and swelling of the fingers, followed by whitening

and loss of feeling, consult your physician before further exposing yourself to cold and

vibration.

Repetitive stress injuries

It is believed that over-using the muscles and tendons of the fingers, hands, arms and shoul-

ders may cause soreness, swelling, numbness, weakness and extreme pain to the areas just

mentioned.

To reduce the risk of repetitive stress injury, do the following:

Avoid using your wrist in a bent, extended or twisted position.

Instead, try to maintain a straight wrist position.

Also, when grasping, use your whole hand, not just the thumb and index finger.

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 the hand and arm muscles.

See a doctor if you feel tingling, numbness or pain in the fingers, hands, wrists or arms.

Relative to EU directive "Vibration"

EU Directive "Vibration" (2002/44/EC) was designed to protect people from safety and health

risks arising from mechanical vibration of a machine by enforcing employers to limit a stand-

ardized 8 hour daily vibration exposure level, A(8).

Any person or organization that employs a person to operate a machine has to take the A(8)

value into account when letting the person use it.

Mechanical vibration values (equivalent vibration value) of this machine, which shall be used

as a guide to simplify the calculation of A(8) value, are as follows:

MODEL Type

Front / Left handle (m/s

2

)3.6

Rear / Right handle (m/s

2

)3.7

10

Machine conditions

Do not operate a chain saw that is damaged, improperly adjusted, or not completely and

securely assembled.

Do not operate the chain saw with a loose or defective silencer.

Be sure that the saw chain stops moving when the throttle control trigger is released.

If your saw is subjected to high loads due to a fall or impact, always perform inspection

and operation check in order to confirm if there is anything wrong before continuing work.

Cutting

Do not operate a chain saw in a tree unless you have been specifically trained to do so.

Keep all parts of your body away from the saw chain when the engine is running.

Use extreme caution when cutting small-size brush and saplings because slender ma-

terial may catch the saw chain and be whipped toward you or pull you off balance.

Stay on the uphill side when bucking or limbing logs which might roll when cut.

When cutting a limb that is under tension, be alert for spring-back so that you will not be

struck by the limb or chain saw when the tension in the wood fibres is released.

Cutting while on a ladder is extremely dangerous because the ladder can slip and your

control of the chain saw is limited.

Working aloft should be left to professionals.

Keep both feet on the ground.

Do not work from off-the-ground positions.

Stop the engine before setting the chain saw down.

Wood practices

Operating a chain saw safely requires a chain saw in proper working order, sound judge-

ment, and knowledge of the methods which should be applied in each cutting situation.

Do not let any person use your saw unless he has read this operator's manual and fully

understands its instructions.

Use your saw only to cut wood or wood products.

Do not cut solid metal, sheet metal, plastics or any non-wood materials.

Services

All chain saw service operations, other than items listed in the operator's manual main-

tenance instructions, should be performed by competent service personnel.

(For example, if an improper tool is used to hold the flywheel in order to remove the clutch,

structural damage to the flywheel could occur and subsequently could cause the flywheel

to burst.)

WARNING

Do not modify a chain saw in any way.

Only attachments and parts supplied by shindaiwa or expressly approved by

shindaiwa for use with the specific shindaiwa chain saw models are authorized.

Although certain unauthorized attachments are useable with the shindaiwa power-

head, their use may, in fact, be extremely dangerous.

CAUTION

Do not touch hot surfaces of cylinder cover and silencer after you used the chain saw.

Operation

Fuel and lubricant

Fuel is a mixture of regular grade petrol and an air-cooled 2-stroke engine oil.

Minimum 89 Octane unleaded 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 13738), JASO

FC, FD grade and shindaiwa recommended oil.

- Never use two-stroke oil intended for water-cooled engines, motor-cycle engines.

- 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.

Chain lubricant

Proper lubrication of the chain while in operation minimizes friction between the chain,

the guide bar and sprocket and also clutch components such as needle bearing and

clutch assembly.

Use shindaiwa genuine chain oil or shindaiwa recommended chain oil specially formulat-

ed for bars and chains for proper lubrication.

These oils contain tackifiers, anti-aging and anti-oxidizing agents.

Consult your shindaiwa dealer for the proper chain oil.

Never use waste or reclaimed oil to avoid various malfunctions on oil system, clutch sys-

tem, chain and guide bar.

Lubrication problems caused by the use of improper oil will void the warranty.

Especially, vegetable based chain oil quickly turns to resin and adheres to oil pump,

chain, guide bar, clutch needle bearing and clutch assembly.

It causes malfunctions and shorten product life.

Flush chain oil system with mineral or chemical based chain oil after use, if it is required to

use vegetable oil due to local / municipal rule or any other reason.

For a short time emergency operation, fresh SAE 10W-30 motor oil can be used.

Cap indication

Fuel and oil tanks are indicated by the following illustrations.

clutch cover and tensioner will be damaged.

18

Correct use of chain brake

Chain brake

The chain brake's function is to stop chain rotation after a kickback.

It neither prevents nor reduces kickback.

Do not depend on the chain brake for protection against kickback.

Even with a chain brake, depend on your own good sense and proper cutting methods just as

though there were no chain brake.

Even with normal use and proper maintenance, the response time of the brake may lengthen.

The following may interfere with the brake's ability to protect the operator:

Saw wrongly held too close to operator's body.

Kickback time may be too fast even for a perfectly maintained brake to work in time.

The operator's hand may not be in position to contact the hand guard.

Brake will not be tripped.

Lack of proper maintenance lengthens the brake's stopping time, making it less effective.

Dirt, grease, oil, pitch, etc. getting into the working parts of the mechanism may lengthen

the stopping time.

Wear and fatigue of the activating brake spring, and wear of the brake / clutch drum and

pivot points may lengthen the brake's stopping time.

A damaged hand guard and lever may render the brake inoperative.

DANGER

Kickback motion is very hazardous.

If the tip of the bar touches wood or the like, the guide bar kicks back in an instant.

The chain brake reduces the possibility of injury due to kickback.

Always check that chain brake works properly before use.

NOTE

For practice, while cutting a small tree, push the front guard forward to engage the

brake.

At all times, confirm whether the brake works properly before each task.

If the chain brake is clogged with wood chips, function of the brake deteriorates a little.

Always keep the device clean.

Do not increase engine revolutions while the chain brake is engaged.

Chain brake is used in emergencies.

Do not use it unless absolutely necessary.

When using throttle latch at starting, keep the chain brake in position.

And after starting the engine, release the brake immediately.

Never test the brake in an area where petrol fumes are present.

Checking the brake function of the brake

1. Place the chain saw on the ground.

2. Hold the handle with both hands and accelerate the engine to high speed by using the

throttle trigger.

3. Operate the chain brake by turning your left wrist against the front hand guard whilst grip-

ping the front handle.

4. The chain stop immediately.

5. Release the throttle trigger.

If the chain does not stop immediately, take the saw to your shindaiwa dealer to repair.

Release the chain brake

When front hand guard is fully pulled towards the operator, chain brake is released.

Non-manual chain brake

1). End of the guide bar may be placed at the height about 35 cm.

2). Rear handle should be gripped lightly with the right hand.

The non-manual chain brake stops the operation of the saw chain in such a manner that the

kickback action produced at the end of the guide bar non-manually actuates the chain brake.

To make sure that the non-manual chain brake operates properly, proceed as follows:

1. Stop the engine of the chain saw.

2. Operate the front and rear handles with hands (grip them lightly), so that the guide bar

may be placed at the height of about 35 cm as shown in Fig.

3. Softly detach the left hand from the front handle, and touch the end of the guide bar

against the wood or the like placed below so that the machine receives an impact.

(* at this time the rear handle should be gripped lightly with right hand)

4. The impact is transferred to the brake lever, which actuates the chain brake.

IMPORTANT

When checking the operation of the non-manual chain brake, use a soft surface substance

like wood to provide the impact so the saw chain is not damaged.

Cutting instruction

General

In all circumstances the operation of the chain saw is a one-man job.

It is difficult at times to take care of your own safety, so don't assume the responsibility for a

helper as well.

After you have learned the basic techniques of using the saw, your best aid will be your own

good common sense.

The accepted way to hold the saw is to stand to the left of the saw with your left hand on the

front handle so you can operate the throttle trigger with your right index finger.

Before attempting to fell a tree, cut some small logs or limbs.

Be thoroughly familiar with the controls and the responses of the saw.

Start the engine, see that is running properly.

Squeeze the trigger to open the throttle wide open, then start the cut.

It is not necessary to press down hard to make the saw cut.

If the chain is properly sharpened, the cutting should be relatively effortless.

Pushing the saw too hard will slow the engine and cutting will actually be more difficult.

Some material may adversely affect the housing of your chain saw.

(Example: palm tree acid, fertilizer etc.)

To avoid housing deterioration carefully remove all packed saw dust around clutch and guide

bar area and wash with water.

DANGER

Do not let the nose or tip of the guide bar touch anything while engine is running to

avoid kickback.

IMPORTANT

Acids from decaying palm tree sap may corrode crankcase and oil tank housings made of

aluminium and magnesium alloys.

To minimize the chance of this occurring, make sure to follow the cleaning procedure listed

below.

Make sure to clean metal parts from palm sap immediately after use.

Remove sprocket cover.

Clean wood chips and sawdust from cover and engine crankcase.

Never use metal tools for cleaning which may scratch the metal paint and allow

corrosion to develop.

Clean sap accumulation from metal parts with cloth and warm water soap.

Rinse with clean water and dry metal surfaces.

Apply a light coating of engine or bar and chain oil to metal parts after they are cleaned.
