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, ill 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 physician 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

CAUTION

Stuffing ears with cotton is not recommended.

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 operator in the eye area.

If conditions warrant that a ventilated face shield be worn, goggles must be worn underneath 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, tiestrings, neckties, cords, chains, jewellery, etc. which could snag the saw chain or underbrush.

• 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.

Fuel

DANGER

• Petrol and fuel are extremely flammable.

If spilled or ignited by ignition source, it can cause fire and serious injury or property 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.

WARNING

1. Oil tank cap

2. Fuel tank cap
   A: Loosening direction
   B: Tightening direction

3. Use an appropriate type of fuel container.

4. 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 remove spark plug lead from spark plug, and put the starter handle into the groove of cap and turn it anticlockwise.

• 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.

Starting engine

• Move the chain saw at least 3m 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

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

3. 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 covered. When transporting the machine, activate the chain brake and secure it properly to prevent flipping over, fuel spills and damage to the unit.

2. Kickback safety precautions

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.

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 accident or injury.

• With a basic understanding of kickback, you can reduce or eliminate the element of surprise.

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 operates the trigger.

Otherwise, this can result in the chain saw "skating" or skidding, which can result in personal 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 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.

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 saw chains specified by the manufacturer.

These guide bars and saw chains that have been approved to meet the kickback requirements.

3. Other safety precautions

Vibration and cold

It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of certain 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 shoulders 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 standardized 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:

Machine conditions

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

• 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

CAUTION

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

• 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 material 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 judgement, 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 maintenance 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.)

Operation

Fuel and lubricant

CAUTION

Whenever opening up the fuel tank, always loosen the cap very slowly and wait for the tank pressure to be equalized before removing the cap.

• 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 formulated 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 system, 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.

2. Momentary stop switch

3. Release throttle trigger and allow engine to idle.

4. Push the momentary stop switch down until the engine is stopped.

Checking chain tension

WARNING

Make sure that the engine is shut off when checking chain tension.

NOTE

Always loosen clutch cover nuts before turning the chain tension adjuster, otherwise the clutch cover and tensioner will be damaged.

• Chain tension should be checked frequently during work and corrected if necessary.
  Tension the chain as tight as possible, but so it can still be pulled easily along the bar by hand.

Chain lubrication test

• Hold the chain just above a dry surface and open the throttle to half speed for 30 seconds.

A thin line of "thrown" oil should be seen on the dry surface.

Pre cutting test

Familiarize yourself with your chain saw before you start actual cutting.
- For this purpose it may be wise to practice by cutting some small logs or limbs several times.
- Do not allow either people or animals into the work area.
Multiple operators - Keep a safe distance between two or more operators when working together simultaneously.

Correct use of chain brake

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.

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.

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 gripping 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

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.

1). End of the guide bar may be placed at the height about 55~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 55 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.

Cutting instruction

DANGER

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

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.

Felling a tree

A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power-line or another tree.

There are ways to make a tree fall where you want it, so first decide where that is!

Before cutting, clear the area around the tree.

You will need good footing while working and you should be able to work the saw without hitting any obstacles.

Next select a path of retreat.

When the tree begins to fall you should retreat away from the direction of fall at a 45-degree angle and at least 3m from the trunk to avoid the trunk kicking back over the stump.

Begin the cut on the side to which the tree is to fall.

Notch: 1/3 of diameter and 30^ to 45^ angle
Back cut: 2.5 to 5 cm higher
Uncut hinge wood: 1/10 of diameter

Cut a notch approximately 1/3 of the way into the tree.

The position of this notch is important since the tree will try to fall "into" the notch.

The felling cut is made on the side opposite the notch.

Make the felling cut by placing spiked bumper 2.5cm to 5cm above the bottom of the notch and stop cutting at approximately 1/10 of diameter to the inner edge of the notch in order to leave the uncut portion of the wood as a hinge.

1. Notch cuts
2. Back cut
3. Wedges (when room)
4. Fall

A:Leave 1/10 of diameter hinge

Do not try to cut through to the notch with the felling cut.

The remaining wood between the notch cut and felling cut will act as a hinge when the tree falls, guiding it in the desired direction.

When the tree starts to fall, stop the engine, place the saw on the ground and make your retreat quickly.

Fell big tree.

1. Notching cuts
2. Draw-across method
3. Back cut
4. Draw-across method
5. Felling cuts

A: Wedges

To fell big trees with a diameter exceeding twice the bar length, start the notching cuts from one side and draw the saw through to the other side of the notch.

Start the back cut on one side of the tree with the spiked bumper engaged, pivoting the saw through to form the desired hinge on that side.

Then remove the saw for the second cut.

Insert the saw in the first cut very carefully so as not to cause kickback.

The final cut is made by drawing the saw forward in the cut to reach the hinge.

Limbing

CAUTION

Don't saw above chest height.

Limbing a fallen tree is much the same as bucking.

Never remove a limb from a tree while it is supporting your weight.

Be careful of the tip touching other limbs.

Always use both hands.

Don't cut with the saw overhead or the bar in a vertical position.

If the saw should kickback, you may not have good enough control to prevent possible injury.

Know how limb is stressed

1. Leave supporting limbs till last.
2. Slide support logs under trunk.
3. If you have thick branches, work from the outside to the inside to avoid your bar and chain get stuck.

Bucking

CAUTION

Stay on the uphill side of logs.

Bucking is the sawing of a log or fallen tree into smaller pieces.

There are a few basic rules which apply to all bucking operations.

Keep both hands on the handles at all times.

Support logs if possible.

When cutting on a slope or hillside, always stand uphill.

No standing on log.

Tension and compression in timber

WARNING

Never use throttle latch for cutting jobs.

CAUTION

If you have misjudged the effects of tension and compression, and cut from the wrong side, the timber will pinch the guide bar and chain, trapping it.

Racing the engine with the chain jammed will burn out your clutch.

If the chain should become jammed and the saw can not be removed from the cut do not force it out.

Stop the saw, force a wedge into the cut to open it up.

Never force the saw when it is jammed.

Do not force the saw into the cut.

A dull chain is unsafe and will cause excessive wear to the cutting attachments.

A good way to tell when the chain is dull is when fine saw dust comes out instead of chips.

1. Hinge
2. Opened
3. Closed

A length of timber lying on the ground will be subject to tension and compression, depending at which points the major support is.

When timber is supported at its ends the compression side is at the top and the tension side is at the bottom.

To cut between these support points, make the first cut downwards approximately 1/3rd the timber diameter.

The second cut is made upwards and should meet the first cut.

Heavy stress

1. 1/3 diameter. To avoid split.
2. Weakening cut to finish.

When the timber is supported at one end only, make the first cut upwards approximately 1/3rd the timber diameter.

The second cut is made downwards and should meet the first cut.

Overbuck

1. Down
   7.Unsupported end

Underbuck

1. Up

2. Wedge

Make angled cut when one section may settle against the other.

WARNING

• All chain saw service operations, other than items listed in the Operator's Manual, should be performed by competent service personnel.
  Fuel vapors are extremely flammable and may cause fire and / or explosion. Never test for ignition spark by grounding spark plug near cylinder plug hole, otherwise serious personal injury may result.

NOTE

When starter grip cannot be pulled lightly, the trouble is diagnosed as failure of engine inside.

Please consult your dealer.

If disassembled inadvertently, it can cause injury.

Saw chain maintenance

WARNING

Switch off the engine and activate the chain brake before sharpening the chain. Always wear gloves when working on chain.

CAUTION

The following faults will increase the risk of kickback considerably.

1) Top plate angle too large
2) File diameter too small
3) Depth gauge too large

NOTE

These angles are referred to as Oregon 91PX, 91VXL and 90PX saw chains. Sharpening at the wrong angle may cause kickback.

• Properly filed cutters are shown below.

A:Top plate angle 30^

B: Top plate cutting angle 55^

C: Depth gauge 0.65 mm
D:Parallel

1.Left hand cutter
2. Tie strap
3. Right hand cutter
4. Depth gauge
5. Drive link
6. Rivet

Never operate a chain saw with a dull or damaged chain.

If the chain requires excessive pressure to cut or produces dust instead of wood chips then inspect the cutters for damage.

When sharpening the chain the objective will be to maintain the same angles and profiles throughout its life as when it was new.

Inspect the chain for damage or wear every time you refuel your chain saw.

Sharpening In order to file the chain correctly you need: round file and file holder, flat file and a depth gauge tool. By using the correct file size (91PX and 91VXL; 4.0~mm Round file, 90PX; 4.5mm Round file) and a file holder, it is easier to receive a good result.

Consult your shindaiwa dealer for correct sharpening tools and sizes.

1. Lock the chain - push the front hand guard forward. To rotate the chain - pull the front hand guard against front handle.

2. Your chain will have alternative left and right hand cutters. Always sharpen from the inside out.

3. Keep the angle lines of the file holder parallel to the line of the chain and file the cutter back until the damaged area (side plate and top plate) has been removed.

4. Hold the file horizontally.

5. Avoid touching the tie straps with the file.

6. Sharpen the most damaged cutter first and then take all the other cutters back to the same length.

7. The depth control determines the thickness of wood chip produced and must be maintained correctly throughout the chain life.

8. As the cutter length is reduced, the depth control height is altered and must be reduced.

9. Position the depth gauge, and file off any of the depth control which protrudes.

10. Round off the front of the depth control to allow smooth cutting.

11. Drive link serves to remove sawdust from the groove of the guide bar. Therefore, keep the lower edge of the drive link sharp.

When setting of the chain is finished, soak it in oil and wash away filings completely before using.

When the chain has been filed on the bar, supply sufficient oil to it, and rotate the chain slowly to wash away the filings before using again.

If the chain saw is operated with filings clogged in the groove, the saw chain and the guide bar will be damaged prematurely.

If the saw chain becomes soiled with resin for instance, clean it with kerosene and soak it in oil.

• Check sprocket when you install new chain. Replace it if worn.
• Check clutch drum, if it rotates freely and smoothly. If not, ask your dealer for repair.

Carburettor

CAUTION

When starting, idle speed adjuster (T) should be adjusted not to rotate the saw chain. When there is some trouble with the carburettor, contact your dealer.

T: Idle speed adjuster

• Do not adjust the carburettor unless necessary.
  To adjust the carburettor proceed as follows:

• Start engine and allow it to run at high idle until warm.

• Turn the idle speed adjuster (T) anticlockwise until the saw chain stops moving.
• Turn idle speed adjuster (T) anticlockwise an additional 1/2 turn.
• Accelerate to full throttle to check for smooth transition from idle to full throttle.
