GENERAL SAFETY PRECAUTIONS

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

Vibration damping system

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 ngers, hands or wrists. The risk increases at low temperatures.

Quick release

There is an easily accessible, quick release tted at the front as a safety precaution in case the engine catches re, or in any other situation that requires you to free yourself from the machine and harness. See instructions under the heading Adjusting the harness and clearing saw.
Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.
Using incorrectly wound cord or a blunt or incorrect cutting attachment (wrong type or incorrectly led, see instructions under the heading Filing the blade) increases the level of vibration.
The machines vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine
Regularly check the vibration damping units for cracks or deformation.
s handle unit.
Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.
Mufer
The mufer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufer tted with a catalytic converter is also designed to reduce harmful exhaust gases.
In countries that have a warm and dry climate there is a signicant risk of re. We therefore fit certain mufflers with a spark arrestor mesh. Check whether the mufer on your machine is tted with this kind of mesh.
For mufers it is very important that you follow the instructions on checking, maintaining and servicing your machine.
English – 9
GENERAL SAFETY PRECAUTIONS
Never use a machine that has a faulty mufer.
Regularly check that the mufer is securely attached to the machine.
If the mufer on your machine is tted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.
WARNING! Mufers tted 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 re!

Locking nut

A locking nut is used to secure some types of cutting attachment.
When tting, 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.
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! The inside of the mufer contain chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a damaged mufer.
WARNING! Bear in mind that:
The exhaust fumes from the engine are hot
!
and may contain sparks which can start a re. Never start the machine indoors or near combustible material!

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.
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.
WARNING! Using an incorrect cutting attachment or an incorrectly sharpened
!
blade increases the risk of kickback.
10 – English
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.
GENERAL SAFETY PRECAUTIONS

Sharpening grass cutters and grass blades

See the cutting attachment packaging for correct sharpening instructions.
Sharpen blades and cutters using a single-cut at le.
Sharpen all edges equally to maintain the balance of the blade.
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 specied type.

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. 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.

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.

Adjusting the harness and clearing saw

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

Standard harness

Quick release

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

Correct balance

Let the cutting attachment rest lightly on the ground. Adjust the position of the support hook to balance the clearing saw correctly.
English – 15
FUEL HANDLING

Fuel safety

Never start the machine:
1 If you have spilt fuel on it. Wipe off the spillage and allow
remaining fuel to evaporate.
2 If you have spilt 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.

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 ames, 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 petrol station to nd 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 tted to the cutting attachment when the machine is being transported or in storage.
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 re, explosion and
!
inhaling fumes.

Fuel

CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of petrol 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 inammable 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.

Petrol

CAUTION! Always use a quality petrol/oil mixture at least 90
octane (RON). If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if it is available.
The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 so-called knocking can occur. This gives rise to a high engine temperature, 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 two­stroke engine oil, which is specially formulated for our air­cooled 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 catalytic converters.
Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.
1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.

FUEL HANDLING

Mixing

Always mix the petrol and oil in a clean container intended for fuel.
Always start by lling 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.
Mix (shake) the fuel mixture thoroughly before lling 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.
WARNING! The catalytic converter mufer gets very hot during and after use. This also
!
applies during idling. Be aware of the re hazard, especially when working near ammable substances and/or vapours.

Fuelling

WARNING! Taking the following precautions, will lessen the risk of re:
!
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
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 before starting.
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 lling the tank.

STARTING AND STOPPING

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 ange is not cracked due to fatigue or due to being tightened too much. Discard the support ange 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.
Starting and stopping
WARNING! The complete clutch cover and shaft must be tted before the machine is
!
started, otherwise the clutch can come loose and cause personal injury.
Always move the machine away from the refuelling area before starting. Place the machine on a at surface. Ensure the cutting attachment cannot come into contact with any object.
Make sure no unauthorised persons are in the working area, otherwise there is a risk of serious personal injury. The safety distance is 15 metres.

Starting

Ignition: Set the stop switch to the start position.
Check that the blade guard is not damaged or cracked. Replace the blade guard if it is 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.
Primer bulb: Press the air purge repeatedly until fuel begins to ll the bulb. The bulb need not be completely lled.
Choke: Set the choke control in the choke position.
-
-
Never use the machine without a guard nor with a defective guard.
All covers must be correctly tted and undamaged before you start the machine.
18 – English
WARNING! When the engine is started with the choke in either the choke or start throttle
!
positions the cutting attachment will start to rotate immediately.
STARTING AND STOPPING
Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!). Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord. Never twist the starter cord around
your hand.
Repeat pulling the cord until the engine starts. When the engine starts. return choke control to run position and apply full throttle; the throttle will automatically disengage from the start setting.
CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.
CAUTION! Do not put any part of your body in marked area. Contact can result in burns to the skin, or electrical shock if the spark plug cap has been damaged. Always use gloves. Do not use a machine with damaged spark plug cap.

Stopping

Stop the engine by switching off the ignition.

WORKING TECHNIQUES

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 often brings added risks, such as icy ground, unpredictable felling direction, etc.
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.
7 Switch off the engine before moving to another area. Fit
the transport guard before carrying or transporting the equipment any distance.
8 Never put the machine down with the engine running
unless you have it in clear sight.
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.
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. Stop the machine immediately if anyone approaches. Never swing the machine around without rst checking behind you to make sure no-one is within the safety zone.

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.
4 Keep a good balance and a rm foothold.
5 Always hold the machine with both hands. Hold the
machine on the right side of your body.
6 Keep the cutting attachment below waist level.
20 – English
WARNING! Sometimes branches or grass get caught between the guard and cutting
!
attachment. Always stop the engine before cleaning.
WARNING! 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 kickback can occur if you attempt to cut thick stems with this area of the blade.
WORKING TECHNIQUES

Grass clearing using a grass blade

Grass blades and grass cutters 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-to-right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.
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 rmly with your feet apart. Move forward after the return stroke and stand rmly 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.
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 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 difcult 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.

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.
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.

MAINTENANCE

Carburettor

Your Husqvarna product has been designed and manufactured to specications 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.
WARNING! The complete clutch cover and shaft must be tted 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.
Adjusting the carburettor means that the engine is adapted to local operating conditions, e.g. climate, altitude, petrol and the type of 2-stroke oil.

Adjusting the idle speed (T)

Check that the air lter is clean. When the idle speed is correct, the cutting attachment should not rotate. If adjustment is required, close (turn clockwise) the idle adjustment screw T, with the engine running, until the cutting attachment starts to rotate. Open (turn anticlockwise) the screw until the cutting attachment stops. The idle speed is correctly set when the engine runs smoothly in all positions, and there is a clear margin to the speed at which the cutting attachment starts to rotate.
Mufer
CAUTION! Some mufers are tted with a catalytic converter. See chapter on Technical data to see whether your machine is tted with a catalytic converter.
The mufer 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 re if directed against dry and combustible material.
Some mufers are equipped with a special spark arrestor mesh. If your machine has this type of mufer, you should clean the mesh at least once a week. This is best done with a wire brush. On mufers without a catalytic converter the mesh should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the mesh should be checked, and if necessary cleaned, monthly. If the mesh is damaged it should be replaced. If the mesh is frequently blocked, this can be a sign that the performance of the catalytic converter is impaired. Contact your dealer to inspect the mufer. A blocked mesh will cause the machine to overheat and result in damage to the cylinder and piston.
CAUTION! Never use a machine with a defective mufer.
WARNING! Mufers tted 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 re!
+
+
--
Note: The machine should only be run for short periods at its highest speed.
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.
22 – English

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.
4
1
2
The cooling system consists of:
1 Air intake on the starter.
2 Fins on the ywheel.
3 Cooling ns 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.

MAINTENANCE
Air lter
The air lter 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.
142R/143R
132R/ 133R
142R/ 143R
Clean the lter every 25 hours, or more regularly if conditions are exceptionally dusty.
Cleaning the air lter
Remove the air lter cover and take out the lter. Wash it clean in warm, soapy water. Ensure that the lter is dry before retting it.
An air lter that has been in use for a long time cannot be cleaned completely. The lter must therefore be replaced with a new one at regular intervals. A damaged air lter must
always be replaced.
If the machine is used in dusty conditions the air lter should be soaked in oil. See instructions under the heading Oiling the air lter.
Oiling the air lter

Bevel gear

The bevel gear is lled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is lled 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.

Spark plug

The spark plug condition is inuenced by:
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type of oil).
A dirty air lter.
These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difculties.
If the machine is low on power, difcult 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 0,6-0,7 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.
Always use HUSQVARNA lter oil, art. no. 531 00 92-48. The lter oil contains a solvent to make it spread evenly through the lter. You should therefore avoid skin contact.
Put the lter in a plastic bag and pour the lter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the lter inside the plastic bag and pour off the excess before tting the lter to the machine. Never use common engine oil. This would drain through the lter quite quickly and collect in the bottom.
An air lter that has been in use for a long time cannot be cleaned completely. The lter must therefore be replaced with a new one at regular intervals. A damaged air lter must
always be replaced.
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 tted with a suppressor.
