Stop switch
Use the stop switch to switch off the engine.
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.
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.
Vibration damping system
Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.
Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration.
The machine¢s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine¢s handle unit.
WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Conta...
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 mesh. Check whether the muffler on your machine is fitted with this kind of mesh.
For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment.
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:
Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated.
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!
Cutting equipment
Grass blades and grass cutters are intended for cutting coarse grass.
A trimmer head is intended for trimming grass.

Muffler
. 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 mesh then it should be cleaned regularly. A blocked mesh causes the engine to overheat, which can lead to serious damage. Never use a muffler with a defective spark arrestor mesh.
Cutting equipment
This section describes how to choose and maintain your cutting equipment in order to:
. Reduce the risk of kickback.
. Obtain maximum cutting performance.
. Extend the life of cutting equipment.
General rules
1 Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
2 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.
3 Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
Locking nut
. When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.)
. Tighten the nut using the socket spanner. 35-50 Nm (3.5- 5 kpm).
CAUTION! The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.
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.
Cutting equipment
IMPORTANT!
This section describes how to choose and maintain your cutting equipment in order to:
Reduce the risk of kickback.
Obtain maximum cutting performance.
Extend the life of cutting equipment.
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.
WARNING! Using an incorrect cutting attachment or an incorrectly sharpened blade increases the risk of kickback.
Sharpening grass cutters and grass blades
. See the cutting attachment packaging for correct sharpening instructions.
. Sharpen blades and cutters using a single-cut flat file.
. Sharpen all edges equally to maintain the balance of the blade.
Trimmer head
. Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engi...
. 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. This will make the line tougher so that it lasts longer.
IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttl...
General safety precautions

3 If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
4 Avoid all skin contact with fuel. Fuel is a skin irritant and may even cause skin changes.
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.
. The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage.
WARNING! Take care when handling fuel. Bear in mind the risk of fire, explosion and inhaling fumes.
General working instructions
IMPORTANT!
This section describes the basic safety precautions for working with clearing saws 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.
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 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 can lead to dangerous conditions, e.g. slippery surfaces.
3 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.
4 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance.
5 Never put the machine down with the engine running unless you have it in clear sight.
Basic working techniques
. Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.
Terms
. Use a grass cutter or grass blade for clearing grass.
. Use a trimmer head or plastic blades for lighter clearing work, for example along verges or around trees.
WARNING! Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.
Grass clearing using a grass blade
. 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...
. 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:
1 Always work at full throttle.
2 Avoid 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 using a trimmer head and plastic blades
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 o...
. 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 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 to and fro.
. When cutting and sweeping you should use full throttle to obtain the best results.
WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the blade is rotating, as this can result in serious injury.
Stop the engine and blade 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.
WARNING! Watch out for thrown objects. Always wear 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. Stop the machine immediately if anyone approaches.

Carburettor
Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has ...
WARNING! The complete clutch cover and shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury.
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 setting of the carburetor means that the engine is adepted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil.
. The carburettor has three adjustment controls:
L = Low speed jet
H = High speed jet
T = Idle adjustment screw
. 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 th...
. 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 carburettor settings are adjusted during testing at the factory. The basic setting is richer than the optimal settin...
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.
Rec. idle speed 2700 rpm
Recommended max. 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.
Fine adjustment
. When the machine has been ”run-in” the carburettor should be finely adjusted. The fine adjustment should be carried out by a qualified person. First adjust the L- jet, then the idling screw T and then the H-jet.
Conditions
. Before any adjustments are made, make sure that the air filter is clean and the air filter cover is fitted. If you adjust the ...
. Carefully turn both jets, L and H, so that they are midway between fully screwed in and fully screwed out.
. Do not attempt to adjust the L and H jets beyond either stop as this could cause damage.
. Now start the machine according to the starting instructions and let it warm up for 10 minutes.
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.

IMPORTANT! 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.
High speed jet H
The high speed jet H affects the engine power, speed, temperature and fuel consumption. If the high speed jet H is set too lean ...
Apply full throttle and turn the high speed jet H very slowly clockwise until the engine slows down. Then turn the high speed je...
Note that the engine should not be under load when you adjust the high speed jet H. You should therefore remove the cutting attachment, nut, support flange and drive disc before adjusting the high speed jet H.
The high speed jet H is adjusted correctly when the machine burbles a little. If the machine races then the setting is too lean. If the engine produces a lot of smoke and burbles a lot then the setting is too rich.
CAUTION! For optimum adjustment of the carburettor, contact a qualified dealer/service workshop that has a revolution counter at their disposal.
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine will accelerate without hesitation and burble a little at maximum speed. ...
If the high speed jet H is set too lean it will result in less power, less performance, poor acceleration and/or damage to the engine.
If both the L and H jets are set too rich it will results in acceleration problems or too low a working speed.
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 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.
On mufflers without a catalytic converter the mesh should be cleaned weekly, or replaced if necessary. On mufflers fitted with a...
If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your ...
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:
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).
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 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, 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...
CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.
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. Ensure that the filter is dry before refitting it.
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.
If the machine is used in dusty conditions the air filter should be soaked in oil. See instructions under the heading Oiling the air filter.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess...
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.
CAUTION! Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury ...
Maintenance schedule
Below you will find some general maintenance instructions. If you need further information please contact your service workshop.
Daily maintenance
. Check throttle trigger and throttle trigger lockout function.
. Check that the stop switch works correctly.
. Check that the blades do not move when the engine is idling.
. Clean the outside of the machine.
. Check that the harness is not damaged.
. Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked.
. 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.
. A non-balanced blade/trimmer head induces heavy vibrations that may damage the machine.
. Check that the blade nut is sufficiently tightened.
. Check that nuts and screws are tight.
. Check that the screws that hold the bevel gear are tight.
. Check that there are no fuel leaks from the engine, tank or fuel lines.
Weekly maintenance
. Check the starter and starter cord.
. Clean the carburettor area.
. Clean the outside of the spark plug. Remove it and check the electrode gap. Adjust the gap to 0.5 mm (.20”), or replace the spark plug. Check that the spark plug is fitted with a suppressor.
. Clean the cooling fins on the cylinder and check that the air intake near the starter is not blocked.
. Check that the bevel gear is filled with grease up to 3/4. Use special grease.
. Clean the air filter.
Monthly maintenance
. Clean the fuel tank.
. Clean the outside of the carburettor and the space around it.
. Clean the fan and the area around it.
. Check fuel hose for cracks or other damage. Change if necessary.
. Change the fuel filter in fuel tank.
. Check the clutch, clutch springs and the clutch drum for wear. Replace if necessary.
. Check electrical wires and connections.
. Replace the spark plug. Check that the spark plug is fitted with a suppressor.
