INTRODUCTION
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 Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During over 300 years of continuous operation, 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 the world of forest and garden products, with quality as our highest priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and construction industry.
Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.
It is our wish that you will be satisfied with your product and that it will be your companion for a long time. Think of this operator′s manual as a valuable document. By following its′ content (using, service, maintenance etc) the life span and the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the operator′s manual, so they will also know how to properly maintain and use it.
Thank you for using a Husqvarna product.
Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.

! |
WARNING! Never use a machine with |
|
faulty safety equipment. The machine’s |
||
|
||
|
safety equipment must be checked and |
|
|
maintained as described in this section. |
|
|
If your machine fails any of these checks |
|
|

|
|
repaired. |
Throttle 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 movement is controlled by two independent return springs.This arrangement means that
the throttle control is automatically locked at the idle setting.
A
B
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.
See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must
1155676-49 Rev. 2 2013-03-14 |

GENERAL SAFETY PRECAUTIONS
be checked. See instructions under the heading Maintenance.
Stop switch
Use the stop switch to switch off the engine.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
Vibration damping system
Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.
The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit.
Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.
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. The risk increases at low temperatures.
Muffler
The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A muffler fitted with a catalytic converter is also designed to reduce harmful exhaust gases.
In countries that have a warm and dry climate there is a significant risk of fire. We therefore fit certain mufflers with a spark arrestor screen. Check whether the muffler on your machine is fitted with this kind of screen.
For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your machine.
Never use a machine that has a faulty muffler.
8 – English |
1155676-49 Rev. 2 2013-03-14 |
GENERAL SAFETY PRECAUTIONS
Regularly check that the muffler is securely attached to the machine.
If the muffler on your machine is fitted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage.
! |
WARNING! Mufflers fitted with catalytic |
|
converters get very hot during use and |
||
|
remain so for some time after stopping. |
|
|
This also applies at idle speed. Contact |
|
|
can result in burns to the skin. |
|
|
Remember the risk of fire! |
|
! |
WARNING! The inside of the muffler |
|
contain chemicals that may be |
||
|
carcinogenic. Avoid contact with these |
|
|
elements in the event of a damaged |
|
|
muffler. |
|
! |
WARNING! Bear in mind that: |
|
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! |
||
|
Harness
Check that the harness is not damaged.
In an emergency situation, release yourself from machine and harness according to the following method.
Cutting equipment
This section describes how you can achieve maximum clearing capacity and extend the life of the cutting attachment through correct maintenance and using the right type of cutting attachment.
•Only use cutting equipment recommended by us!
•Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.
•Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
•Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
•Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.

GENERAL SAFETY PRECAUTIONS
WARNING! Never use a machine with ! faulty safety equipment. The machine’s
safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.
WARNING! Always stop the engine ! before doing any work on the cutting
attachment.This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.
Specification of bar and saw chain
When the cutting attachment supplied with your machine has to be replaced, because it is worn out or damaged, you must only fit the types of bar and saw chain recommended by us.
Guide bar
•Length (inches/cm)
•Number of teeth on bar tip sprocket (T). Small number = small tip radius = low risk of kickback.
•Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.
•Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.
•Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links.
•Lubrication hole and hole for the chain tensioner.
Saw chain
•Saw chain pitch (inches). (The distance between three drive links, divided by two.)
•Drive link width (mm/inches)
10 – English |
1155676-49 Rev. 2 2013-03-14 |
GENERAL SAFETY PRECAUTIONS
•Number of drive links.
Level of kickback reduction. The only thing that describes the level of kickback reduction offered by a saw chain is its model number.

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 cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.
•A sharp chain eats its way through the wood and produces long, thick cuttings.
•The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip
(B). The cutting depth is determined by the difference in height between the two.
A B
•When you sharpen a cutting tooth there are five important factors to remember.
- Filing angle
- Cutting angle
-File position
-Round file diameter
- File depth

GENERAL SAFETY PRECAUTIONS
gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.
! |
WARNING! Departure from the |
|
sharpening instructions considerably |
||
|
||
|
increases the risk of kickback. |
|
Sharpening cutting teeth |
||
To sharpen cutting teeth you will need a round file and a file gauge.
•Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difficult to sharpen correctly.
•Always file cutting teeth from the inside face outwards. Reduce the pressure on the return stroke. File all the teeth on one side of the bar first. Then turn the saw over and file the remaining teeth from the other side.
•File all the teeth to the same length. When the length of the cutting teeth is reduced to 5/32 inch (4 mm) the chain is worn out and should be replaced.
min 4 mm (0,16”)
General advice on setting raker clearance
•When you sharpen the cutting teeth you reduce the raker clearance (=cutting depth). To maintain optimal cutting performance you must file back the raker lip to the recommended height.
•On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance.
•We recommend that you use our raker gauge to achieve the correct clearance and bevel on the raker lip.

•Before setting the raker clearance the cutting teeth should be newly sharpened.
12 – English |
1155676-49 Rev. 2 2013-03-14 |
GENERAL SAFETY PRECAUTIONS
We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.
•To adjust the raker clearance you will need a flat file and a raker gauge.
•Place the gauge over the raker lip.
•Place the file over the part of the lip that protrudes through the gauge and file off the excess. The clearance is correct when you no longer feel any resistance as you draw the file over the gauge.
Tensioning the chain |
||
! |
WARNING! A slack chain may jump off |
|
the bar and cause serious or even fatal |
||
|
||
|
injury. |
|
•The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
•Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check the tension more frequently.
•Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.
- Undo the bar nut.
- Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain should be tensioned until it does not sag from the underside of the bar.
- Tighten the bar nut using the combination spanner. Check that the chain can be pulled round easily by hand.
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 has a vegetable oil base. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage.
•If our own chain oil is not available, standard chain oil is recommended.
1155676-49 Rev. 2 2013-03-14 |
English – 13 |
GENERAL SAFETY PRECAUTIONS
•In areas where oil specifically for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used.
•Never use waste oil! This is dangerous for yourself, the machine and the environment.
Filling with chain oil
The oil pump is preset at the factory to satisfy most lubrication requirements. A full oil tank normally lasts about the same time as a full fuel tank. Therefore check the amount of oil in the oil tank when filling the fuel to prevent damage to the saw chain and bar that may arise due to a lack of lubrication.
Checking chain lubrication
•Check the chain lubrication each time you refuel. Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.
Adjusting chain lubrication
When cutting dry or hard species of wood it may be necessary to increase lubrication.Turn the adjuster screw clockwise to increase the oil flow. Remember that this will increase oil consumption, check the level in the oil tank
regularly. Turn the adjuster screw anticlockwise to decrease the oil flow.
What to do if lubrication does not work:
•Check that the oil channel in the bar is not obstructed. Clean if necessary.
•Check that the oil channel in the gear housing is clean. Clean if necessary.
•Check that the bar tip sprocket turns freely. If the chain lubrication system is still not working after carrying out the above checks you should contact your service workshop.
Checking wear on cutting equipment
Saw chain
Check the chain daily for:
•Visible cracks in rivets and links.
•Whether the chain is stiff.
14 – English |
1155676-49 Rev. 2 2013-03-14 |
GENERAL SAFETY PRECAUTIONS
•Whether rivets and links are badly worn.
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 5/32 inch (4 mm) the chain must be replaced.
min 4 mm (0,16”)
Chain drive sprocket
Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive.
Guide bar
Check regularly:
•Whether there are burrs on the edges of the bar. Remove 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 daily.

The chain should be tensioned until it fits snugly on the underside of the bar.
•The chain is correctly tensioned when there is no slack on the underside of the bar, and it can still be turned easily by hand. Tighten the bar nut with the combination spanner while holding up the tip of the bar.
•When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life.
Fitting the impact guard (only some models)
If the machine has a impact guard bolted under the engine this should be removed before the impact guard is assembled.
Fit the guard using the three screws and washers. Fit the two short screws in hole A. Tighten the screws to a torque

FUEL HANDLING
Fuel safety
Never start the machine:
1If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.
2If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.
3If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
Transport and storage
•Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.
•When storing and transporting fuel always use approved containers intended for this purpose.
•When storing the machine for long periods the fuel tank must be emptied. Contact your local gas station to find out where to dispose of excess fuel.
•Ensure the machine is cleaned and that a complete service is carried out before long-term storage.
•The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage.
•Secure the machine during transport.
•In order to prevent unintentional starting of the engine, the spark plug cap must always be removed during long-term storage, if the machine is not under close supervision and when performing all service measures.

WARNING! Take care when handling fuel. |
|
Bear in mind the risk of fire, explosion |
||
|
||
|
and inhaling fumes. |
Fuel
CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine 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! Fuel and fuel fumes are |
|
highly inflammable and can cause |
||
|
||
|
serious injury when inhaled or allowed to |
|
|
come in contact with the skin. For this |
|
|
reason observe caution when handling |
|
|
fuel and make sure there is adequate |
|
|
ventilation. |
Gasoline
CAUTION! Always use a quality gasoline/oil mixture with an octane rating of at least 87 octane ((RON+MON)/2). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded gasoline/oil mixture. Leaded gasoline will destroy the catalytic converter.
Use low-emission gasoline, also known as alkylate gasoline, if it is available.
This engine is certified to operate on unleaded gasoline.
•The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 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 at continuous high revs a higher octane rating is recommended.
Two-stroke oil
•For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two stroke-engines.
•Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).
•Never use oil intended for four-stroke engines.
•Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.

•Whenever possible position yourself so that you can make the cut at right angles to the branch.
90°
•Do not work with the shaft held straight out in front of you (like a fishing rod) as this increases the apparent weight of the cutting attachment.
•Cut large branches in sections so that you have better control over where they fall.
•Never cut through the swelling at the root of the branch as this will slow down healing and increase the risk of fungal attack!
•Make an initial cut on the underside of the branch before cutting through the branch. This will prevent tearing of the bark, which could lead to slow healing and cause permanent damage to the tree. The cut should not be deeper than 1/3 of the branch thickness

MAINTENANCE
Carburetor
Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in.To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/ service workshop (who will have a rev counter at their disposal) to adjust your carburettor.
Function
•The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine.
•The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil.
•The carburetor has three adjustment controls: L = Low speed jet
H = High speed jet
T = Idle adjustment screw
H L
T
•The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anti-clockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed.
•The T-screw regulates the throttle setting at idle speed. If the T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.
Basic setting
•The basic carburetor settings are adjusted during testing at the factory. The basic setting is richer than the optimal setting and should be maintained for the first few hours the machine is in use. The carburettor should then be finely adjusted. Fine adjustment should be carried out by a skilled technician.
CAUTION! If the cutting attachment rotates when the engine is idling the idle adjustment screw T should be turned anti-clockwise until the cutting attachment stops.
Adjustment of the idle speed
Before any adjustments are made, make sure that the air filter is clean and the air filter cover is fitted.
Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.
Rec. idle speed: See the Technical data section.
WARNING! If the idle speed cannot be ! adjusted so that the cutting attachment
stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.
Muffler
CAUTION! Some mufflers are fitted with a catalytic converter. See chapter on Technical data to see whether your machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may
26 – English |
1155676-49 Rev. 2 2013-03-14 |
MAINTENANCE
cause fire if directed against dry and combustible material.
Some mufflers are equipped with a special spark arrestor screen. If your machine has this type of muffler, you should clean the screen at least once a week. This is best done with a wire brush.
On mufflers without a catalytic converter the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the screen should be checked, and if necessary cleaned, monthly. If the screen is damaged it should be replaced.
If the screen is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked screen will cause the machine to overheat and result in damage to the cylinder and piston. See also instructions under the heading Maintenance.
CAUTION! Never use a machine with a defective muffler.
! |
WARNING! Mufflers fitted with catalytic |
converters get very hot during use and |
|
|
remain so for some time after stopping. |
|
This also applies at idle speed. Contact |
|
can result in burns to the skin. |
|
Remember the risk of fire! |
Cooling system
To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:
1Air intake on the starter.
2Fins on the flywheel.
3Cooling fins on the cylinder.
4Cylinder cover (directs cold air over the cylinder).
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.
1155676-49 Rev. 2 2013-03-14 |
English – 27 |
MAINTENANCE
Spark plug
The spark plug condition is influenced by:
•Incorrect carburetor 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, which may result in operating problems and starting difficulties.
If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0,5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.
CAUTION! 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.
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
•Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water.
IMPORTANT! Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others.Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by HUSQVARNA.
Gear
IMPORTANT!
All service on the saw head must be carried out by an authorized Husqvarna dealer. Always use Husqvarna's original grease to prevent damage to the gear in the saw head.
Use grease with part number: 579 06 49-01
