INTR ODUCTION

Dear Customer,

Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During the more than 300 years in existence, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the ﬁrst motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working today.

Today Husqvarna is one of the leading manufacturers in

orld of forest and garden products, with quality as

and safely. Attend a training course in chain saw usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available. Work is constantly in progress to improve the design and technology - improvements that increase your safety and efﬁciency. Visit your dealer regularly to see whether you can beneﬁt from new features that have been introduced.

Personal protective equipment

WARNING! Most chain saw accidents happen when the chain touches the operator. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.

• Approved protective helmet

• Hearing protection

• Protective goggles or a visor

• Gloves with saw protection

• Trousers with saw protection

• Boots with saw protection, steel toe-cap and non-slip sole

• Always have a ﬁrst aid kit nearby.

• Fire Extinguisher and Shovel

Generally clothes should be close-ﬁtting without restr

equipment must be inspected and maintained. See instructions under the heading Checking, maintaining and servicing chain saw safety equipment. If your machine does not pass all the checks, take the saw to a servicing dealer for repair.

Chain brake and front hand guard

Your chain saw is equipped with a chain brake that is designed to stop the chain if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.

Take care when using your saw and make sure the kickback zone of the bar never touches any object.

• The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism.

• The brake is applied when the front hand guard (B) is pushed forwards or when the right-hand brake trigger (E) is pushed up and forwards.

• This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).

• The front hand guard is not designed solely to activate the chain brake. Another important feature is that it reduces the risk of your left hand hitting the chain if you lose grip of the front handle.

• The chain brake must be engaged when the chain sa

(46)

• Use the chain brake as a ”parking brake” when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by. Do not leave the chain saw switched on with the chain brake activated for long periods. The chain saw can become very hot.

• The chain brake is released by moving the front hand guard mar towards the front handle.

• Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw ﬁrmly and not let go.

• The way the chain brake is activated, either manually or automatically by the inertia release mechanism, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes.

If you get a violent kickback while the kickback zone of the bar is f designed to be activated by the inertia in the kickback direction.

If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake will be activated manually by the movement of your left hand.

• In the felling position the left hand is in a position that mak impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action.

Will my hand always activate the chain brake during a kickback?

No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake. You should also maintain a ﬁrm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you.

There are also certain positions in which your hand cannot reach the front hand guard to activ brake; for example, when the saw chain is held in felling position.

Will my inertia activated chain brake always activate during kickback in the event of a kickback?

No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do before you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance.

Will my chain brake always protect me from injury in the event of a kickback?

No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you.

Only you and proper working technique can eliminate kickback and its danger.

1158605-39 Rev.3 2016-09-20

GENERAL SAFETY PRECAUTIONS

Throttle trigger lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting.

(10)

Chain catcher

The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).

Right hand guard

Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.

The machine transfer of vibration between the engine unit/cutting equipment and the machine chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.

Cutting hardwoods (most broadleaf trees) creates more vibr with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.

WARNING! Overexposure to vibration can lead to circulatory damage or nerve

damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. These symptoms may be increased in cold temperatures.

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

In areas with a hot, dry climate there is a high risk of ﬁres. These areas are sometimes subject to go requiring among other things the mufﬂer must be equipped with an approved type of spark arrestor mesh.

(14)

When ﬁtting the mesh, make sure that the mesh is inserted in the right position. If necessary, use the combination spanner to insert or remove the mesh.

CAUTION! The mufﬂer gets very hot during and after use. This also applies during idling. Be aware of the ﬁre hazard, especially when working near ﬂammable substances and/or vapours.

WARNING! Never use a saw without a mufﬂer, or with a damaged mufﬂer. A damaged mufﬂer may substantially increase the noise level and the ﬁre hazard. Keep ﬁre ﬁghting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.

A chain is made up of a number of links, which are available in standard and low-kickback versions.

IMPORTANT! No saw chain design eliminates the danger of kickback.

Sharpening your chain and adjusting depth gauge setting

General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you

have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings.

• A sharp chain eats its way through the wood and

produces long, thic

It is very difﬁcult to sharpen a chain correctly without the r

ight equipment. We recommend that you use our ﬁle gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.

See instructions under the heading Technical data for information about sharpening your chain.

WARNING! Departure from the sharpening instructions considerably increases the risk of kickback.

Sharpening cutting teeth

To shar pen cutting teeth you will need a round ﬁle and a ﬁle gauge. See instructions under the heading Technical data for information on the size of ﬁle and gauge that are recommended for the chain ﬁtted to your chain saw.

• Check that the chain is correctly tensioned. A slack

1158605-39 Rev.3 2016-09-20

GENERAL SAFETY PRECAUTIONS

• Always ﬁle cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side ﬁrst, then turn the chain saw over and ﬁle the teeth on the other side.

• File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (5/32") the chain is w

General advice on adjusting depth gauge setting

• When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be ﬁled down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to ﬁnd the correct depth gauge setting for your particular chain.

Adjustment of depth gauge setting

• The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.

• You will need a ﬂat ﬁle and a depth gauge tool. We recommend that y acheive the correct depth gauge setting and bevel for the depth gauge.

• Place the depth gauge tool over the chain. Detailed inf will be found on the package for the depth gauge tool. Use the ﬂat ﬁle to ﬁle off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the ﬁle along the depth gauge tool.

Tensioning the chain

Lubricating cutting equipment

WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.

Chain oil

Chain oil must demonstrate good adhesion to the chain and also maintain its ﬂow characteristics regardless of whether it is warm summer or cold winter weather.

As a chain saw manufacturer we have developed an optimal chain oil which, with its vegetable oil base, is also biodegradable. We recommend the use of our own oil for both maximum chain life and to minimise environmental

GENERAL SAFETY PRECAUTIONS

damage. If our own chain oil is not available, standard chain oil is recommended.

Never use waste oil! Using waste oil can be dangerous to you and damage the machine and environment.

IMPORTANT! When using vegetable based saw chain oil, dismantle and clean the groove in the bar and saw chain before long-term storage. Otherwise there is a risk of the saw chain oil oxidizing, which will result in the saw chain becoming stiff and the bar tip sprocket jamming.

Filling with chain oil

• All our chain saws have an automatic chain lubrication system. On some models the oil ﬂow is also adjustable.

• The saw chain oil tank and the fuel tank are designed so that the fuel r

However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as recommended (a lean mixture may mean that the fuel lasts longer than the oil) and that you also use the recommended cutting equipment (a bar that is too long will use more chain oil).

Checking chain lubrication

• Check the chain lubrication each time you refuel. See instructions under the heading Lubricating the bar tip sprocket.

Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) a throttle you should see a distinct line of oil on the light surface.

If the chain lubrication is not working:

• Check that the oil channel in the bar is not obstructed. Clean if necessar

• Check that the groove in the edge of the bar is clean. Clean if necessary.

• Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.

If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your service agent.

Checking wear on cutting equipment

Check the chain daily for:

• Visible cracks in rivets and links.

• Whether the chain is stiff.

• Whether rivets and links are badly worn.

Replace the saw chain if it exhibits any of the points abo

ve.

We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn.

When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.

Guide bar

Check regularly:

• Whether there are burrs on the edges of the bar. Remo

ve these with a ﬁle if necessary.

• Whether the groove in the bar has become badly worn. Replace the bar if necessary.

• Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain.

• To prolong the life of the bar you should turn it over regular

ly.

FUEL HANDLING

Fuel

Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol and twostroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Always ensure there is adequate ventilation when handling fuel.

Petrol

• Use good quality unleaded or leaded petrol.

• The lowest recommended octane grade is 90 (RON). If y

ou run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.

• When working with continuous high revs (e.g. limbing) a higher octane is recommended.

Husqvarna alkylate fuel

Husqvarna recommends the use of Husqvarna alkylate fuel for best performance. The fuel contains less dangerous substances compared to regular fuel, which reduces dangerous exhaust fumes. The fuel provides low amount of residues when combusted which keeps the engine parts cleaner and optimizes the engine life. Husqvarna alkylate fuel is not available in all markets.

Ethanol fuel

HUSQVARNA recommends commercial available fuel with maximum 10% ethanol content.

Running-in

Avoid running at a too high speed for extended periods during the ﬁrst 10 hours.

Two-stroke oil

• For best results and performance use HUSQVARNA two-stroke oil, which is specially formulated for our two-stroke engines. Mixture 1:50 (2%).

• If HUSQVARNA two-stroke oil is not available, you

y use another two-stroke oil of good quality that is

ma intended for air cooled engines. Contact your dealer when selecting an oil.

• Never use two-stroke oil intended for water-cooled outboard engines oil.

• Never use oil intended for four-stroke engines.

Mixing

• Always mix the petrol and oil in a clean container intended for fuel.

• Always start by ﬁlling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.

Chain oil

• We recommend the use of special oil (chain oil) with good adhesion characteristics.

• Never use waste oil. This results in damage to the oil pump, the bar and the chain.

• It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature.

• In temperatures below 0°C (32°F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components.

• Contact your service agent when choosing chain oil.

FUEL HANDLING

Fueling

WARNING! Taking the following precautions, will lessen the risk of ﬁre:

Do not smoke and do not place any hot objects in the vicinity of fuel.

Always stop the engine and let it cool for a few minutes before refuelling.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area and source before starting.

Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel ﬁlter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always ﬁll the chain oil tank and fuel tank at the same time.

(43)

WARNING! Fuel and fuel vapour are highly ﬂammable. Take care when

handling fuel and chain oil. Be aware of the risks of ﬁre, explosion and those associated with inhalation.

3 If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines

WARNING! Never use a machine with visible damage to the spark plug guard and ignition cable. A risk of sparking arises, which can cause a ﬁre.

Transport and storage

• Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked ﬂames from electrical equipment, electric motors, relays/switches, boilers and the like.

• Always store fuel in an approved container designed

or that purpose.

• For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emptied. Ask where you can dispose of waste fuel and chain oil at your local petrol station.

• The guide bar cover must always be ﬁtted to the cutting attachment when the machine is being

ansported or in storage, in order to prevent accident

tr contact with the sharp chain. Even a non-moving chain can cause serious cuts to yourself or persons you bump into with an exposed chain.

• Remove the spark plug cap from the spark plug.

• Secure the machine during transport.

Long-term storage

Empty the fuel/oil tanks in a well ventilated area. Store the fuel in approved cans in a safe place. Fit the guide bar cover. Clean the machine. See instructions under the heading Maintenance schedule.

Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

Fuel safety

• Never refuel the machine while the engine is running.

• Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-strok

STARTING AND STOPPING

Starting and stopping

WARNING! Note the following before starting:

The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting.

Never start a chain saw unless the bar, chain and all covers are ﬁtted correctly. Otherwise the clutch can come loose and cause personal injuries.

Place the machine on ﬁrm ground. Make sure you have a secure footing and that the chain cannot touch anything.

Keep people and animals well away from the working area.

Basic safety rules

1 Look around you:

• To ensure that people, animals or other things cannot aff

ect your control of the machine.

• To make sure that none of the above might come within reach of your saw or be injured by falling trees.

CAUTION! Follow the instructions above, but do not use a chain saw in a situation where you cannot call for help in case of an accident.

2 Do not use the machine in bad weather, such as

og, heavy rain, strong wind, intense cold, etc.

y are not damaged or missing.

3 Take great care when removing small branches and

void cutting bushes (i.e. cutting many small branches

a at the same time). Small branches can be grabbed by the chain and thrown back at you, causing serious injury.

4 Make sure you can move and stand safely. Check the

area around y branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

5 Take great care when cutting a tree that is in tension.

A tree that is in tension ma position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury.

WARNING! Sometimes chips get stuck in the clutch cover causing the chain to jam. Always stop the engine before cleaning.

General rules

1 If you understand what kickback is and how it happens

then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent.

2 Always hold the chain saw ﬁrmly with your right hand

on the rear handle and y handle. Wrap your ﬁngers and thumbs around the handles. You should use this grip whether you are right-handed or left-handed. This grip minimises the effect of kickback and lets you keep the chain saw under control.

3 Most kickback accidents happen during limbing. Make

sure you are standing ﬁrmly and that there is nothing in the way that might make you trip or lose your balance.

Lack of concentration can lead to kickback if the

kback zone of the bar accidentally touches a

saw chain and be thrown towards you. Even if this does not need to be a danger, you may be surprised and lose control of the saw. Never saw stacked logs or branches without ﬁrst separating them. Only saw one log or one piece at a time. Remove the cut pieces to keep your working area safe.

4 Never use the chain saw above shoulder height

and try not to cut with the tip of the bar. Never use the chain saw one-handed!

5 You must have a steady stance in order to have full

control over the chain saw. Never work standing on a ladder, in a tree or where you do not have ﬁrm ground to stand on.

6 Always use a fast cutting speed, i.e. full throttle.

7 Take great care when you cut with the top edge of the

bar This is known as cutting on the push stroke. The chain tries to push the chain saw back towards the user. If the saw chain is jamming, the saw may be pushed back at you.

8 Unless the user resists this pushing force there is a

risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree, which will lead to a kickback.

Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting on the pull stroke. In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting. Cutting on the pull stroke gives the operator better control over the chain saw and the position of the kickback zone.

9 Follow the instructions on sharpening and maintaining

your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See instructions under the headings Cutting equipment and Technical data.

Basic cutting technique

WARNING! Never use a chain saw by holding it with one hand. A chain saw is

not safely controlled with one hand. Always have a secure, ﬁrm grip around the handles with both hands.

General

• Always use full throttle when cutting!

• Reduce the speed to idle after every cut (running the engine f

or too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage).

• Cutting from above = Cutting on the pull stroke.

• Cutting from below = Cutting on the push stroke.

Cutting on the push stroke increases the risk of kickback. See instructions under the heading How to avoid kickback.

(53)

(56)

Terms

Cutting = General term for cutting through wood.

Limbing = Cutting branches off a felled tree.

Splitting = When the object you are cutting breaks off bef

ore the cut is complete.

There are ﬁve important factors you should consider before making a cut:

1 Make sure the cutting equipment will not jam in the

(59)

cut.

2 Make sure the object you are cutting will not split. (58)

3 Make sure the chain will not strike the ground or any

other object during or after cutting.

4 Is there a risk of kickback? (4)

5 Do the conditions and surrounding terrain affect how

safely you can stand and move about?

Two factors decide whether the chain will jam or the object

ou are cutting will split: the ﬁrst is how the object is

that y supported before and after cutting, and the second is whether it is in tension.

In most cases you can avoid these problems by cutting in

o stages; from the top and from the bottom. You need to

tw support the object so that it will not trap the chain or split during cutting.

IMPORTANT! If the chain jams in the cut: stop the engine! Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw.

The following instructions describe how to handle the commonest situations y using a chain saw.

Limbing

When limbing thick branches you should use the same approach as for cutting.

Cut difﬁcult branches piece by piece. (61)

Cutting

WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.

If you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually.

Remove the cut pieces from the cutting area. By leaving them in the cutting area, y inadvertently getting a kickback, as well as increasing the risk of losing your balance while working.

Tree felling technique

IMPORTANT! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task that you feel unsure of!

Safe distance

The safe distance between a tree that is to be felled and anyone else working nearby is at least 2 1/2 tree lengths. Make sure that no-one else is in this ”risk zone” before or during felling.

Felling direction

The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely.

Once you have decided which way you want the tree to fall

ou must judge which way the tree would fall naturally.

Several factors affect this:

• Lean of the tree

• Bend

• Wind direction

• Arrangement of branches

• Weight of snow

• Obstacles within the reach of the tree: for example, other trees

• Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to.

You may ﬁnd you are forced to let the tree fall in its natural direction because it is impossib make it fall in the direction you ﬁrst intended.

(64)

Another very important factor, which does not affect the

elling direction but does affect your safety, is to make sure

f the tree has no damaged or dead branches that might break off and hit you during felling.

The main point to avoid is letting the tree fall onto another

tree there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.

IMPORTANT! During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard.

Clearing the trunk and preparing your retreat

Delimb the stem up to shoulder height. It is safer to work from the top down and to have the tree between you and the saw.

Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees away from the intended felling direction.

1 Danger zone

2 Retreat path

3 Felling direction

Felling

Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you ﬁnish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately.

Directional cuts

To make the directional cut you begin with the top cut. Aim using to the saw’s felling direction mark (1) toward a goal further forward in the terrain, where you would like the tree to fall (2). Stand on the right-hand side of the tree, behind the saw, and cut with a pull stroke.

Next make the bottom cut so that it ﬁnishes exactly at the end of the top cut.

The directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45

The line where the two cuts meet is called the directional cut line right angles (90

(71)

24 – English

1158605-39 Rev.3 2016-09-20

WORKING TECHNIQUES

The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke.

Make the felling cut about 3-5 cm (1.5-2 inches) above the bottom directional cut.

Set the spiked bumper (if one is ﬁtted) just behind the felling hinge. Use full throttle and advance the chain/bar slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction. Drive a wedge or breaking bar into the cut as soon as it is deep enough.

Finish the felling cut parallel with the directional cut line so that the distance betw trunk diameter. The uncut section of the trunk is called the felling hinge.

The felling hinge controls the direction that the tree falls in.

(75)

All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed.

When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar.

We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to ﬁnd out which lengths of bar are recommended for your saw.

There are methods for felling trees with a diameter larger than the bar length. much greater risk that the kickback zone of the bar will come into contact with the tree.

Freeing a tree that has fallen badly

Freeing a ”trapped tree”

It is very dangerous to remove a trapped tree and there is high accident risk.

Never try to fell the tree that is trapped.

Never work in the risk zone of the hanging trapped tree.

(78)

The safest method is to use a winch.

• Tractor-mounted

• Portable

Cutting trees and branches that are in tension

Preparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more).

Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch.

General advice:

Position yourself so that you will be clear of the tree or branch when the tension is released. 1158605-39 Rev.3 2016-09-20

Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufﬁcient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension.

Never cut straight through a tree or branch that is in tension!

If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep.

Continue to cut deeper until tree/limb bends and tension is released.

Cut tree/limb from outside the bend, after tension has been released.

How to avoid kickback

WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.

Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object.

Kickback only occurs if the kickback zone of the bar touches an object.

Limbing

Make sure that you can stand and move about safely. Work on the left side of the trunk. Work as close as possible to the chain saw for maximum control. If possible, let the weight of the chain saw rest on the trunk.

Keep the trunk between you and the chain saw as you

ve along the trunk.

Cutting the trunk into logs

See instructions under the heading Basic cutting technique.

(4)

WARNING! A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back toward you and cause loss of control resulting in injury.

MAINTENANCE

General

The user must only carry out the maintenance and service work described in this Operator's Manual. More extensive work must be carried out by an authorized service workshop.

Carburettor adjustment

Your Husqvarna product has been designed and manufactured to speciﬁcations that reduce harmful emissions.

Function

• The carburettor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburettor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine.

• The T-screw regulates the throttle setting at idle

Basic settings and running in

The basic carburettor settings are adjusted during testing at the factory. Fine adjustment should be carried out by a skilled technician.

Rec. idle speed: See the Technical data section.

Fine adjustment of the idle speed T

Adjust the idle speed with the T-screw. If it is necessary to re-adjust, turn the T-screw clockwise while the engine is running, until the chain starts to rotate. Then turn anticlockwise until the chain stops. When the idle speed is correctly adjusted the engine should run smoothly in every position and the engine speed should be safely below the speed at which the chain starts to rotate.

If the T-screw is turned clockwise this gives a

speed. higher idle speed; turning it anti-clockwise gives a lower idle speed.

Checking, maintaining and servicing chain saw safety equipment

Note! All service and repair work on the machine demands special training. This is especially true of the machine’s safety equipment. If your machine fails any of the checks described below we recommend that you take it to your service workshop.

Chain brake and front hand guard

Checking brake band wear

Brush off any wood dust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair operation of the brake.

Regularly check that the brake band is at least 0,6 mm thick at its thinnest point.

Checking the front hand guard

Make sure the front hand guard is not damaged and that there are no visible defects such as cracks.

Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover.

Checking the inertia brake release

(84)

WARNING! Contact your servicing dealer, if the idle speed setting cannot be

adjusted so that the chain stops. Do not use the chain saw until it has been properly adjusted or repaired.

Correctly adjusted carburettor

When the carburettor is correctly adjusted the machine accelerates without hesitation and 4-cycles a little at full throttle. It is also important that the chain does not rotate at idle. If the L-jet is set too lean it may cause starting difﬁculties and poor acceleration. If the H-jet is set too lean the machine will have less power, poor acceleration and could suffer damage to the engine.

Throttle trigger lockout

• Make sure the throttle control is locked at the idle setting when the throttle lockout is released.

• Press the throttle lockout and make sure it returns to its original position when you release it.

• Check that the throttle trigger and throttle lockout move freely and that the return springs work properly.

(92)

• Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburettor idle adjustment.

Chain catcher

Check that the chain catcher is not damaged and is ﬁrmly attached to the body of the chain saw.

Right hand guard

Check that the right hand guard is not damaged and that there are no visible defects, such as cracks.

CAUTION! The start/stop switch automatically returns to run position. In order to prevent unintentional starting, the spark plug cap must be removed from the spark plug when assembling, checking and/or performing maintenance.

Mufﬂer

Never use a machine that has a faulty mufﬂer.

Regularly check that the mufﬂer is securely attached to the machine. (95)

Some mufﬂers are equipped with a special spark arrestor mesh. If your machine has this type of mufﬂer, you should clean the mesh at least once a week. This is best done with a wire brush. A blocked mesh will cause the engine to overheat and may lead to serious damage.

Note! The mesh must be replaced if it is damaged. If the

Starter housing

WARNING! When the recoil spring is wound up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury.

Care must be exercised when replacing the return spring or the starter cord. Wear protective glasses and protective gloves.

Replacing the starter cord

Regularly check the vibration damping units for cracks or deformation. Make sure the vibration damping units are securely attached to the engine unit and handle unit.

Stop switch

Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Air ﬁlter

The air ﬁlter must be regularly cleaned to remove dust and dirt in order to avoid:

• Carburettor malfunctions.

• Starting problems.

• Loss of engine power.

• Unnecessary wear to engine parts.

The spark plug condition is inﬂuenced by:

• Incorrect carburettor adjustment.

• An incorrect fuel mixture (too much or incorrect type of oil).

• A dirty air ﬁlter.

These factors cause deposits on the spark plug electrodes starting difﬁculties.

If the machine is low on power, difﬁcult to start or runs poor before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,5 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.

Note! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is ﬁtted with a suppressor.

1158605-39 Rev.3 2016-09-20

MAINTENANCE

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1 Air intake on the starter.

2 Air guide plate.

3 Fins on the ﬂywheel.

4 Cooling ﬁns on the cylinder.

5 Cylinder cover (directs cold air over the cylinder).

(104)

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

”Air Injection” centrifugal cleaning

Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan.

IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the ﬁns on the ﬂywheel, the space around the ﬂywheel, inlet pipe and carburettor compartment.

Winter use

Running problems can occur when using the machine in the cold and snowy conditions caused by:

• Too low engine temperature.

• Icing of the air ﬁlter and carburettor.

Special measures are therefore often required:

• Partly mask the air inlet on the starter to increase the w

orking temperature of the engine.

Temperature -5°C or colder

(105)

Otherwise there is a risk of overheating, resulting in severe damage to the engine.

IMPORTANT! Any maintenance other than that described in this man dealer (retailer).

ual must be carried out by your servicing

For running the machine in cold weather or powder snow, a special cover is available, which is mounted on the starter housing. This reduces the intake of cold air and prevents large amounts of snow from being sucked in.
