Dear customer!

Cong ratulations 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

GLO VES Gloves should be worn when necessary, e.g., when ﬁtting

cutting attachments.

BOOTS Wear boots with steel toe-caps and non-slip sole.

CLOTHING Wear clothes made of a strong fabric and avoid loose

clothing that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level.

FIRST AID KIT Always have a ﬁrst aid kit nearby.

Mac hine ′ s safety equipment

This section descr ibes the machine ′ s safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the ”What is what?” section to locate where this equipment is positioned on your machine.

The life span of the machine can be reduced and the risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information please contact your nearest servicing dealer.

Thr ottle 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 movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting.

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.

IMPORTANT! All servicing and repair work on the machine requires

special training. This is especially true of the machine

′s safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your nearest service agent.

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.

GENERAL SAFETY PRECAUTIONS

1154807-49 rev.no 1 2015-06-15

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 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.

Cutting attachment guard

This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the

operator from accidental contact with the cutting attachment.

Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked.

Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.

Vibration damping system

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

Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment.

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! Never use a cutting attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is ﬁtted this can cause serious personal injury.

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. These 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.

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.

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.

NOTE! Make sure that the spark arrestor is screwed in place

correctly.

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!

GENERAL SAFETY PRECAUTIONS

1154807-49 rev.no 1 2015-06-15

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to:

• Reduce the risk of blade thrust.

• Obtain maximum cutting performance.

• Extend the life of cutting equipment.

Cutting equipment

Saw blades are intended for cutting ﬁbrous types of wood.

Grass blades and grass knifes are intended for cutting coarse grass.

A trimmer head is intended for trimming grass.

General rules

Only use cutting attachments with the guards we recommend! See the chapter on Technical data.

Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended ﬁle gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.

Keep the correct setting on the saw blade! Follow our instructions and use the recommended setting tool. An incorrectly set saw blade increases the risk of jamming and blade thrust, and damage to the saw blade.

Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.

Sharpening grass knifes and grass blades

• See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut ﬂat ﬁle.

IMPORTANT! Only use cutting attachments with the guards we

recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to

check the correct way to load the cord and the correct cord diameter.

Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.

Maintain the correct blade setting! Follow our instructions and use the recommended ﬁle gauge.

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 spark plug cap before you start to work on it.

WARNING! Using an incorrect cutting attachment or an incorrectly sharpened blade increases the risk of blade thrust.

GENERAL SAFETY PRECAUTIONS

English – 11

1154807-49 rev.no 1 2015-06-15

• Sharpen all edges equally to maintain the balance of the blade.

Sharpening the saw blade

• See the cutting attachment packaging for correct sharpening instructions.

A correctly sharpened blade is essential for working efﬁciently and to avoid unnecessary wear to the blade and brush cutter.

• Make sure that the blade is well supported when you ﬁle it. Use a 5.5 mm round ﬁle with a ﬁle holder.

• The ﬁling angle is 15°. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a ﬂat ﬁle, in exceptional cases. If so, this should be done before ﬁling with a

round ﬁle. The top edges must be ﬁled down by the same amount for all the teeth.

Adjust the blade setting. This should be 1 mm.

Trimmer head

• Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.

• Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared.

• The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

• Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in water for a couple of days before use. This will make the cord tougher so that it lasts longer.

WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the speciﬁed type.

IMPORTANT! Always ensure the trimmer cord is wound tightly and

evenly around the drum, otherwise the machine will generate harmful vibration.

Adjusting the harness and brush cutter

Standard harness

Quick release

At the front is an easily accessible, quick release. Use this if the engine catches ﬁre or in any other emergency situation that requires you to free yourself from the machine and harness.

Spreading the load on your shoulders

A well-adjusted harness and machine makes work much easier. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across both shoulders.

Correct height

Adjust the shoulder strap so that the cutting attachment is parallel to the ground.

Correct balance

Let the cutting attachment rest lightly on the ground. If you use a saw blade it should balance about 10 cm above the ground to prevent contact with stones and the like. Adjust the position of the suspension ring to balance the brush cutter correctly.

WARNING! When using a brush cutter it must always be hooked securely to the harness. Otherwise you will be unable to control the brush cutter safely and this can result in injury to yourself or others. Never use a harness with a defective quick release.

FUEL HANDLING

16 – English

1154807-49 rev.no 1 2015-06-15

Fuel safety

Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and

allow remaining fuel to evaporate.

2 If 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.

3 If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines. In the event of leakage, contact your service agent.

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 open 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. Drain the tank into the appropriate containers and in a well ventilated area.

• 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.

• Allow the hedge trimmer to cool down after use before putting it away for storage.

Fuel

CAUTION! The machine is equipped with a two-stroke

engine and must always be 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.

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.

Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than E10 will create lean running condition which can cause engine damage.

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.

• A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of the catalytic converters.

• Mixing ratio 50:1 (2%) with HUSQVARNA two-stroke oil.

WARNING! Take care when handling fuel. Bear in mind the risk of ﬁre, explosion and inhaling fumes.

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.

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

FUEL HANDLING

English – 17

1154807-49 rev.no 1 2015-06-15

Mixing

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

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

• Mix (shake) the fuel mixture thoroughly before ﬁlling the machine’s fuel tank.

• Do not mix more than one month’s supply of fuel at a time.

• If the machine is not used for some time the fuel tank should be emptied and cleaned.

Fueling

• Always use a fuel container with an anti-spill valve.

• If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.

• Clean the area around the fuel cap. Contamination in the tank can cause operating problems.

• Ensure that the fuel is well mixed by shaking the container before ﬁlling the tank.

WARNING! The catalytic converter 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 vapors.

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

Mix and pour fuel outdoors, where there are no sparks or ﬂames.

Do not smoke or place hot objects near fuel.

Always shut off the engine before refueling.

Always stop the engine and let it cool for a few minutes before refueling. Mix and pour fuel outdoors, where there are no sparks or ﬂames. Refuel in a well ventilated area. Never fuel the machine indoors.

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

Tighten the fuel cap carefully after refueling.

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

STARTING AND STOPPING

18 – English

1154807-49 rev.no 1 2015-06-15

Check before starting

Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.

• Check that the support ﬂange is not cracked due to fatigue or due to being tightened too much. Discard the support ﬂange if it is cracked.

Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm.

• Check that the trimmer head and trimmer guard are not damaged or cracked. Replace the trimmer head or trimmer guard if they have been exposed to impact or are cracked.

• Never use the machine without a guard nor with a defective guard.

• All covers must be correctly ﬁtted and undamaged before you start the machine.

General working instructions

Basic safety rules

1 Look around you:

• To ensure that people, animals or other things cannot affect your control of the machine.

• To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.

• CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

2 Inspect the working area. Remove all loose objects,

such as stones, broken glass, nails, steel wire, string, etc. that could be thrown out or become wrapped around the cutting attachment.

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

dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.

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

area around you for possible obstacles (roots, rocks, 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 under

tension. A tree that is under tension may spring back to its normal 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.

6 Keep a good balance and a ﬁrm foothold. Do not

overreach. Keep proper footing and balance at all times.

7 Always hold the machine with both hands. Hold the

machine on the right side of your body. Connect the machine to the suspension ring on the harness Keep all parts of your body away from the hot surfaces. Keep all parts of your body away from the rotating cutting attachment.

8 Keep the cutting attachment below waist level. 9 Switch off the engine before moving to another area.

Fit the transport guard before carrying or transporting the equipment any distance.

10 Never put the machine down with the engine running

unless you have it in clear sight.

IMPORTANT! This section describes the basic safety precautions for

working with brush cutters and trimmers. If you encounter a situation where you are uncertain

how to proceed you should ask an expert. Contact your dealer or your service workshop.

Avoid all usage which you consider to be beyond your capability.

You must understand the difference between forestry clearing, grass clearing and grass trimming before use.

WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury.

Stop the engine and cutting equipment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burnt if you touch it.

WORKING TECHNIQUES

1154807-49 rev.no 1 2015-06-15

Working methods

• Before you start clearing, check the clearing area, the type of terrain, the slope of the ground, whether there are stones, hollows etc.

• Start at whichever end of the area is easiest, and clear an open space from which to work.

• Work systematically to and fro across the area, clearing a width of around 4-5 m on each pass. This exploits the full reach of the machine in both directions

and gives the operator a convenient and varied working area to work in.

• Clear a strip around 75 m long. Move your fuel can as work progresses.

• On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it.

• You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind conditions, so that cleared stems fall in the cleared area of the stand.

Forestry clearing using a saw blade

• The risk of blade thrust increases with increasing stem size. You should therefore avoid cutting with the area of the blade between 12 o’clock and 3 o’clock.

• To fell to the left, the bottom of the tree should be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting ﬁrm pressure. At the same time push the stem using the blade guard. Cut with the area of the blade between 3 o’clock and

WARNING! Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury.

Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. (50 ft.) Stop the machine immediately if anyone approaches. Never swing the machine around without ﬁrst checking behind you to make sure no-one is within the safety zone.

WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

WARNING! Machines ﬁtted with saw blades or grass blades can be thrown violently to the side when the blade comes into contact with a ﬁxed object. This is called blade thrust. A blade thrust can be violent enough to cause the machine and/or operator to be propelled in any direction, and possibly lose control of the machine. Blade thrust can occur without warning if the machine snags, stalls or binds. Blade thrust is more likely to occur in areas where it is difﬁcult to see the material being cut.

Avoid cutting with the area of the blade between the 12 o’clock and 3 o’clock positions. Because of the speed of rotation of the blade, blade thrust can occur if you attempt to cut thick stems with this area of the blade.

WORKING TECHNIQUES

22 – English

1154807-49 rev.no 1 2015-06-15

5 o’clock. Apply full throttle before advancing the blade.

• To fell to the right, the bottom of the tree should be pushed to the left. Tilt the blade and bring it diagonally up to the right. Cut with the area of the blade between 3 o’clock and 5 o’clock so that the direction of rotation of the blade pushes the bottom of the tree to the left.

• To fell a tree forwards, the bottom of the tree should be pulled backwards. Pull the blade backwards with a quick, ﬁrm movement.

• Large stems must be cut from two sides. First determine which direction the stem will fall. Make the ﬁrst cut on the felling side. Then ﬁnish cutting the stem from the other side. Adjust the cutting pressure to match the size of the stem and the hardness of the wood. Small stems require more pressure, while large stems require less pressure.

• If the stems are tightly packed, adapt your walking pace to suit.

• If the blade jams in a stem, never jerk the machine free. If you do this the blade, bevel gear, shaft or handlebar may be damaged. Release the handles, grip the shaft with both hands and gently pull the machine free.

Brush cutting with a saw blade

• Thin stems and brush are mown down. Work with a sawing movement, swinging sideways.

• Try to cut several stems in a single sawing movement.

• With groups of hardwood stems, ﬁrst clear around the group. Start by cutting the stems high up around the outside of the group to avoid jamming. Then cut the stems to the required height. Now try to reach in with the blade and cut from the centre of the group. If it is still difﬁcult to gain access, cut the stems high up and let them fall. This will reduce the risk of jamming.

Grass clearing using a grass blade

• Grass blades and grass knifes must not be used on woody stems.

• A grass blade is used for all types of tall or coarse grass.

• The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-toright is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.

WORKING TECHNIQUES

English – 23

1154807-49 rev.no 1 2015-06-15

• If the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.

• Try to work rhythmically. Stand ﬁrmly with your feet apart. Move forward after the return stroke and stand ﬁrmly again.

• Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.

• Reduce the risk of material wrapping around the blade by following these instructions:

1Always work at full throttle. 2Avoid the previously cut material during the return

stroke.

• Stop the engine, unclip the harness and place the machine on the ground before you start to collect the cut material.

Grass trimming with a trimmer head

Trimming

• Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.

• The cord can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts.

• Reduce the risk of damaging plants by shortening the cord to 10-12 cm and reducing the engine speed.

Clearing

• The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord.

• The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.

• When trimming and clearing you should use less than full throttle (80%) so that the cord lasts longer and to reduce the wear on the trimmer head.

Cutting

• The trimmer is ideal for cutting grass that is difﬁcult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.

• Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

Sweeping

• The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool side to side.

• When cutting and sweeping you should use full throttle to obtain the best results.

IMPORTANT! To avoid unbalance and vibrations in handles trimmer

head cover need to be cleaned every time cord is reﬁlled. In addition, check other part of the head if needed to be cleaned.

MAINTENANCE

1154807-49 rev.no 1 2015-06-15

Carburetor

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

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 counter clockwise 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.

Recommended idle speed: See the Technical data section.

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

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.

CAUTION! Never use a machine with a defective mufﬂer.

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.

MAINTENANCE

1154807-49 rev.no 1 2015-06-15

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 Fins on the ﬂywheel. 3 Cooling ﬁns on the cylinder. 4 Cylinder cover (directs cold air over the cylinder). 5 Mufﬂer cover 6 Mufﬂer plate 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.

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 0,026 inch

(0,65 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

Close the choke control by setting the choke into a choke position.

Remove the air ﬁlter cover and take out the ﬁlter. Wash it clean in warm, soapy water. Clean also the inside of the ﬁlter cover by using air or a brush. Ensure that the ﬁlter is dry before reﬁtting it.

MAINTENANCE

26 – English

1154807-49 rev.no 1 2015-06-15

Remove the Felt ﬁlter from the ﬁlter holder and gently brush debris from the ﬁlter. Check the rubber sealing surface. Change the ﬁlter on the rubber seal if damaged.

An air ﬁlter that has been in use for a long time cannot be cleaned completely. The ﬁlter must therefore be replaced with a new one at regular intervals.

A damaged air ﬁlter

must always be replaced.

Damaged, very dirty, or fuel-

soaked air ﬁlter must always be replaced.

Bevel gear

The bevel gear is ﬁlled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is ﬁlled three-quarters full with grease. Use HUSQVARNA special grease.

The grease in the bevel gear does not normally need to be changed except if repairs are carried out.

Two-piece shaft (525RK)

The drive shaft end in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive shaft ends (splined coupling) on models with two-piece shafts will seize if they are not lubricated regularly.

CAUTION! 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.
