FOIRE AUX QUESTIONS - 266 HUSQVARNA

Quel mélange huile-essence utiliser pour la tronçonneuse Husqvarna 266 ?

Utilisez un mélange à 2% (1:50) avec l'huile deux-temps Husqvarna, ou 4% (1:25) avec une huile deux-temps standard. Reportez-vous au tableau de mélange dans la notice.

Comment démarrer la tronçonneuse à froid ?

Mettez le contact, tirez le starter, ouvrez les gaz à fond, enclenchez le verrouillage des gaz. Placez le pied sur le carter, tirez sur le lanceur. Après 2-3 tentatives, l'engine démarre. Poussez le starter et accélérez pour désengager le verrouillage.

Comment régler le carburateur ?

Les vis L (ralenti) et H (plein gaz) se règlent en tournant. Vissez-les à fond puis dévissez L de 1 tour et H de 3/4 de tour. Ajustez L pour obtenir le ralenti maximal, puis ouvrez de 10 min horloge. Ajustez H pour que le moteur 4-temps, puis ouvrez de 10 min. Le ralenti final se règle avec la vis T.

Comment tendre la chaîne ?

Desserrez les écrous du guide, relevez le nez du guide et tournez la vis de tension pour que la chaîne ne pend pas en dessous. Ne la serrez pas trop fort : elle doit pouvoir être tirée à la main. Resserrez les écrous.

Quelle huile utiliser pour la lubrification de la chaîne ?

Utilisez une huile de chaîne de qualité, adhésive. Par temps froid, optez pour une huile d'hiver. L'huile de boîte EP 90 peut être utilisée en dépannage. Ne jamais utiliser d'huile de vidange.

Comment nettoyer le filtre à air ?

Retirez le couvercle du cylindre, dévissez et soulevez le filtre. Séparez les deux moitiés, nettoyez-les à l'eau savonneuse tiède, séchez à l'air comprimé. Remontez en veillant à l'étanchéité.

Comment régler le frein de chaîne Swed-o-Matic ?

La force de déclenchement se règle en modifiant l'écart entre la vis de déclenchement et la poignée avant. Testez avec un dynamomètre : la charge doit être de 10-15 kp pour un guide de 15 pouces. Vérifiez en laissant tomber la tronçonneuse d'environ 35 cm sur un tronc.

Quelle est la capacité des réservoirs ?

Le réservoir de carburant contient 0,75 litre et le réservoir d'huile 0,45 litre.

Quels équipements de sécurité sont recommandés ?

Portez un casque, des protections auditives, des gants en cuir, des vêtements adaptés et des chaussures de sécurité. Utilisez le frein de chaîne lors des pauses et du transport.

Comment changer le câble du lanceur ?

Dévissez les quatre vis du lanceur, retirez-le, tirez le câble de 30 cm et placez-le dans l'encoche. Détendez le ressort, dévissez la vis centrale et retirez la poulie. Remplacez le câble et le ressort si nécessaire. Remontez en lubrifiant le ressort.

Assembling guide bar and chain

A. Undo the guide bar nuts and remove the clutch cover and transport packing piece.
B. Place the guide bar into its rearmost position. Make sure that the chain tensioning stud is properly in the hole in the guide bar

C. Fit the chain around the drive sprocket and in the groove of the bar. Start on the upper side of the guide bar.

Make sure that the cutting edges of the sawing teeth along the top of the guide bar are facing towards the tip. Also check that the drive links go down properly into the drive sprocket.
D. Tension the chain so it does not sag along the bottom of the guide bar. Check that the chain and guide bar fit properly.

Fit the clutch cover and tighten the nut fingertight only. Pull the chain a few turns around by hand and check that it can move freely.

E. Tension the chain while holding up the bar tip. Do not tension the chain stronger than it can be pulled around by hand. Tighten the guide bar nuts.

NOTE!

Do not forget to "run in" the chain and guide bar. Please see the chain manufacturer's recommendation.

CHECK THE CHAIN TENSION FREQUENTLY FOR OPTIMAL PERFORMANCE AND DURABILITY.

Fuel and oil

The power plant of this chain saw is a twostroke engine, that is run on a petrol- and oil mixture of certain proportions acc. to the table.

Do not use but a twostroke oil of high quality, e.g. Husqvarna Twostroke Oil, that is specially developed for chain saws.

NOTE!

No extra oil is needed in the petrol during the running-in period of the chain saw.

For lubricating the chain and guide bar we recommend a chain lubricating oil with good adhesive properties.

During the wintertime at air temperatures below 0^ (32^) some types pf chain lubricating oils are viscous. This can cause overloading of the oil pump,

which can result in damage of the pump drive and pump parts. Under cold weather conditions it is therefore necessary to use a "wintergrade" oil which stays fluent even when cold.

Concerning the choice of oil and its suitability at different air temperatures, please refer to your Husqvarna dealer.

Always use quality chain oil. If not available use gear box oil type EP 90.

ALWAYS TOP UP WITH FUEL AND CHAIN LUBRICANT AT THE SAME TIME.

NOTE!

On no account waste oil should be used as this can damage the oil pump.

Oil mixture:

Husqvarna Twostroke Oil 1:50 (2%)

Ordinary twostroke oil 1:25 (4%)

Chain brake activator "Swed-o-Matic"

The Swed-o-Matic should release the chain brake at a certain load on the guide bar tip.

Adjusting the release power

The distance between the Swed-o-Matic release screw and the front handle (B) determines the release power. A smaller gap means reduced release power.

The release power can be checked as follows: Push the guide bar tip against a spring balance. With a 15^ guide bar the chain brake should be released at a load of 10-15 kp.

The forestry worker could make a rough check on the spot as follows: Hold the saw horizontally over a trunk, at a height of abt 35cm . As the saw by force of its own weight swings around the rear handle and hits the trunk, the brake should be released.

Note that during this check the engine must not be running. If the brake is not released, contact your service workshop.

Nut M should be tightened completely.

Maintenance of the chain brake

Clean the brake band and the mechanism. Check that the band has at least 0.75mm thickness on the most worn part.

Lubricate the links and supports of the brake mechanism with two-stroke oil. Release and lock the brake repeatedly to check that the mechanism works smoothly.

Check the chain brake function regularly. Start the saw on clear ground making sure that the chain runs freely. Apply full throttle and release the chain brake. The chain should immediately stop rotating. If not, contact your service workshop.

Starting the chain saw

A. Cold engine

1. Switch on the ignition (push the switch to the left so that the 1 is visible).
2. Pull out the choke control.
3. Push down the throttle trigger lockout (A).
4. Open the throttle fully (B).
5. Push the throttle latch backwards (C).

Now all the controls are in starting position and the chain saw is ready to be started.

6 Put your right foot on the plate beneath the rear handle.
7. Grasp the front handle with your left hand and press the saw against the ground.
8. Grasp the starter handle with your right hand and pull out the starting cord slowly until the starter pawl engage.
9. Give the starting cord a short sharp tug.

NOTE!

Do not pull the starting cord entirely out or release the starter handle in pulled out position, as this can cause damages on the chain saw.
10. Normally the engine will start after 2-3 starting attempts. Push the choke control as soon the engine starts. Open rapidly the throttle wide and the latch will disengage.

To stop the engine push the ignition switch to the right so that the O is visible.

B. Warm engine

Use the same starting procedure as for cold engine but without pulling out the choke control.

NOTE!

One of the most common causes of starting difficulties is that too many starting attempts have been made with a closed choke flap. If this is the case, remove the spark plug and wipe it dry. Open the choke flap fully.

Before you reassemble the spark plug, we recommend you to pull the starter handle several times to "ventilate the cylinder", the ignition switch in 0-position.

Assemble the spark plug and make a new starting attempt with open choke flap and full throttle.

CAUTION!

Guide bar, chain and clutch cover must be assembled before the engine is started, otherwise the clutch may come loose and cause injuries.

Adjusting the carburettor

The carburettor has three adjusting screws:

L = Low speed needle
H = High speed needle
T = Throttle adjusting screw

A. Basic setting

Clean the air filter

Check the spark plug and its electrodes.

Check that the fuel filter is not clogged.

Screw the needles H and L carefully right in.

Then screw the needles out to recommended basic position:

$$ H = 3 / 4 \text {t u r n o u t}, L = 1 \text {t u r n o u t} $$

Start the engine and warm it up. Adjust the idling speed by means of the throttle adjusting screw to that speed at which the chain just starts rotating.

B. Adjustment of L-needle

1. Screw in the L-needle slowly and the speed will increase. Screw in the needle a little further and the speed will slow down again as the fuel supply becomes too "lean". Notice the position of the needle at the highest speed.
2. Open the L-needle again and notice the highest position. Note that the speed slows down at "richer" supply.
3. Adjust the L-needle to the highest speed position. Then open it equivalent to 10 min on a clock-face to obtain a somewhat "richer" supply to aid acceleration.
4. By means of the T-screw, adjust the idling speed to 2.300-2.500 r/min, ensuring that the chain does not rotate when engine is idling.
5. Give full throttle a couple of times to check that the engine "responds". If not, open the L-needle by abt 3 min. Check again.

C. Adjustment of H-needle

At correct adjustment of the H-needle the engine should be four-stroking. Screw in the H-needle slowly until there is no more four-stroking. Then screw the needle out equivalent to 10 min on a clockface.

Check by means of a revolution counter that the high idle speed does not exceed 11.500 r/min.

Cleaning the air filter

A clean air filter is necessary for optimal carburettor function and optimal engine power.

In order to get at the air filter, remove the cylinder cover by undoing the retaining screws and lifting the cover off upwards-backwards.

Remove the heaviest dirt from the air filter. Undo the screw and lift the filter off carefully to prevent dirt from falling down into the carburettor.

Separate the two filter halves by means of a screwdriver or a knife.

Clean the filter halves carefully in warm soapy water.

Avoid cleaning them in chain saw petrol.

Dry the filter with compressed air.

Reassemble the filter and make sure that it lies close to the carburettor.

Use two air filters alternately.

Clean the filter each day!

Changing starter cord and return spring

Loosen the four screws that retain the starter. Remove the starter. Pull out the cord approx. 30~cm and lift it up into the notch in the periphery of the pulley.

Zero-set the return spring by carefully letting the pulley rotate backwards.

Undo the screw in the centre of the pulley and remove the pulley.

In case you change the return spring as well, undo the screws that retain the plastic cassette, which then can be removed.

Change the spring and lubricate it with engine oil.

Assemble the remaining parts in reverse order. Lift up the starter cord into the notch on the pulley. Tension the return spring by turning the pulley clockwise about two turns.

NOTE!
Make sure that it is possible to turn the pulley at least 1/4 of a turn further when the cord is fully pulled out.

Winter use

In winter, extreme cold and powdery snow can cause running problems.

The cylinder cover is prepared for extreme cold working conditions. In the partition wall of the cover there is a hole, that is covered by a cap (A) when operating at normal temperatures.

In case of extreme cold, this cap shall be removed so that heated air from the cylinder can flow into the carburettor space and prevent the air filter from being iced up.

NOTE! Under normal temperature conditions the cap has to be mounted. Otherwise there is a certain risk of overheating the chain saw.

Adjusting the oil pump capacity

The oil pump is adjustable for four different capacities. Adjustment is to be done after removal of chain, guide bar, clutch cover, centrifugal clutch and clutch drum.

With a screwdriver the oil capacity can be adjusted by turning the screw. The index on the screw should face the capacity wanted. Figure shows the position for capacity 2.

Recommended positions: Bar 15":Pos.2. Bar 18^ and more:Pos.3-4.

Before assembling the clutch drum check that the washer between drum and sealing ring is not lost.

Daily maintenance

1. Clean the saw body from the outside.
2. Clean the air filter. Change if necessary.
3. Turn around the guide bar, lower edge up. Clean the bar groove.
4. Clean the fan and air intakes in the starter cover.
5. Clean the cooling fins on the cylinder
6. Clean the space under the clutch cover.
7. Sharpen the chain and check its tension.
8. Check the oiling system for the chain and the guide bar.
9. Clean the chain brake. Make it a habit to lock the chain brake during pauses and transports.

Weekly maintenance

1. Check the starter, its cord and return spring.
2. Clean the spark plug from the outside and check the gap. Adjust the gap or change the plug if necessary.
3. File off burrs if any on the sides of the guide bar.
4. Lubricate the bearings of the clutch drum.

Monthly maintenance

1. Wash out the fuel tank with petrol.
2. Wash out the oil tank with petrol.
3. Clean the carburettor.
4. Check the fire-fighting screen inside the silencer. Clean or change if necessary.
