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 water-powered 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.

Machine s safety equipment

This section describes 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.

Check that the throttle control and throttle lock move freely

and that the return springs work properly.

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.

See instructions under the heading Start. Start the machine

and apply full throttle. Release the throttle and check that the

sweeper rollers stops and remains at a standstill. If the

sweeper rollers rotates with the throttle in the idle position

then the carburettor idle setting must be checked. See

instructions under the heading Maintenance.

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.

Throttle lock

The throttle lock 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 lock 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.

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

Make sure the throttle control is locked at the idle setting

when the throttle lock is released.

Your machine is equipped with a vibration damping system

that is designed to reduce vibration and make operation

easier.

English – 7

Download from Www.Somanuals.com. All Manuals Search And Download.

SAFETY INSTRUCTIONS

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 that the mufﬂer is securely attached to the

machine.

If the mufﬂer on your machine is ﬁtted 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.

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.

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!

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.

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.

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.

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!

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.

FUEL HANDLING

Gasoline

Fuel safety

Never start the machine:

If you have spilt fuel on it. Wipe off the spillage and allow

remaining fuel to evaporate.

CAUTION! Always use a quality petrol/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 petrol/

oil mixture. Leaded petrol will destroy the catalytic converter.

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.

If the machine is leaking fuel. Check regularly for leaks

from the fuel cap and fuel lines.

Use low-emission gasoline, also known as alkylate gasoline,

if it is available.

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.

This engine is certiﬁed to operate on unleaded gasoline.

•

When storing and transporting fuel always use approved

containers intended for this purpose.

•

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 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.

•

When working at continuous high revs a higher octane

rating is recommended.

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.

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.

WARNING! Take care when handling fuel.

Bear in mind the risk of ﬁre, explosion and

inhaling fumes.

•

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

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.

FUEL HANDLING

Mixing

Fueling

•

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.

WARNING!Taking the following precautions,

will lessen the risk of ﬁre:

•

Mix (shake) the fuel mixture thoroughly before ﬁlling the

machine’s fuel tank.

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.

•

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

•

Clean the area around the fuel cap. Contamination in the

tank can cause operating problems.

If the machine is not used for some time the fuel tank

should be emptied and cleaned.

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 vapours.

WORKING TECHNIQUES

Basic working techniques

General working instructions

Safety instructions while working

IMPORTANT!

•

Keep a good balance and a ﬁrm foothold.

This section describes the basic safety precautions for

working with the sweeper.

Always hold the machine with both hands. Hold the

machine on the right of your body.

If you encounter a situation where you are uncertain how to

proceed you should ask an expert. Contact your dealer or

your service workshop.

•

Never use other parts of the body to manoeuvre the

machine.

Keep your hands and feet away from the sweeper when

the engine is running.

Avoid all usage which you consider to be beyond your

capability.

When the engine has been switched off, keep your hands

and feet away from the sweeper until it has come to a

complete stop.

Basic safety rules

•

Always use full throttle when using the sweeper.

The sweeper works best when the rubber blades can

quickly slide over or stroke the surface. New or replaced

sweeper rollers tend to stick or drag on hard surfaces, and

should therefor be run in properly before use. The easy

way run them in is to run the machine at full throttle for 3-

5 minutes on loose gravel or a similarly abrasive material.

After running-in, the sweeper can easily clear a wide

variety of materials, from snow and puddles of water, to

heavier objects such as gravel and wood chippings. With

practice you will learn how the sweeper works, but you

must think of safety right from the start!

•

Look around you:

To ensure that people, animals or other things cannot

affect your control of the machine.

•

To prevent the above-mentioned from coming into contact

with the sweeper or being hit by loose objects that are

thrown out.

•

CAUTION! Do not use the machine unless you are able

to call for help in the event of an accident.

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

fog, heavy rain, strong wind, intense cold, etc. To work in

bad weather conditions is tiring and can create dangerous

circumstances, e.g. slippery surfaces.

•

Always drop to idling speed after each working operation.

Longer periods running at full throttle without loading the

engine (that is without resistance, which the engine feels

from the sweeper rollers when sweeping) can lead to

serious engine damage

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.

If heavy vibration occurs, stop the machine. Disconnect

the HT lead from the spark plug. Check that the machine

is not damaged. Repair any damage.

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.

The engine must be switched off before moving.

Never put the machine down with the engine running

unless you have it in clear sight.

The bevel gear can get hot during use and

may remain so for a while afterwards.You

could get burnt if you touch it.

Do not over-reach.

Keep sweeper rollers below waist level.

•

Run the sweeper at full (or almost full) throttle, with the

rubber blades resting on the surface.

When you want to clear narrow areas, such as

pavements, the machine can be used so that it throws the

material straight ahead of you. If you want to cover wider

areas you may need to work at an angle so that long

heaps build up on one side. Long heaps consisting of light

material can be gathered together in a single line or pile

for collecting later, while hard or bulky material may have

English – 13

WORKING TECHNIQUES

to be collected in several long heaps. To clear in corners

you can change the direction of rotation by turning over

the machine.

WARNING! When you turn the machine over,

litter is thrown backwards towards the user.

Use a lower engine speed when you reverse

with the machine and remember that it is

easy to trip over material that is thrown out!

•

Keep your working angle low.

A large working angle could cause you to lose control!

•

CAUTION! It is both tiring and unnecessary to raise the

rubber blades or hold them above the surface while you

are working.

WARNING! Maintain a low working angle

with the surface! If the working angle is high

the sweeper will tend to move towards you

and there is a risk you will lose control over

the machine.

The sweeper rollers may start turning when

the sweeper is started! Always hold the

machine ﬁrmly when you start it up. Watch

out for objects that could become entangled

in the rotating sweeper rollers or thrown out

by them.

ALWAYS WATCH OUT FOR OBJECTS THAT

ARE THROWN OUT!

Even though the sweeper rollers do not exert

the same force as a lawn mower blade, for

example, you should avoid working with

materials that could cause damage to people

or property if they are thrown out.

MAINTENANCE

Basic setting

Carburetor

•

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.

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.

CAUTION! If the sweeper rollers rotates/moves while the

engine is idling, the T-screw should be turned anti-clockwise

until the sweeper rollers stops.

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.

Rec. idle speed 2700 rpm

Recommended max. speed: See theTechnical data section.

WARNING! If the idling speed cannot be

adjusted so that the sweeper rollers stops,

contact your service workshop. Do not use

the machine until it has been correctly

adjusted or repaired.

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.

Fine adjustment

•

When the machine has been ”run-in” the carburetor

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.

•

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.

Conditions

The carburetor has three adjustment controls:

L = Low speed jet

•

Before any adjustments are made, make sure that the air

ﬁlter is clean and the air ﬁlter cover is ﬁtted. If you adjust

the carburettor when the air ﬁlter is dirty it will result in a

leaner mixture when the ﬁlter is ﬁnally cleaned. This can

lead to serious engine damage.

H = High speed jet

T = Idle adjustment screw

•

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 sweeper rollers rotates/moves while the

engine is idling, the T-screw should be turned anti-

clockwise until the sweeper rollers stops.

•

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.

MAINTENANCE

Low speed jet L

High speed jet H

Try to ﬁnd the highest idling speed, turning the low speed

needle L clockwise respectively counter-clockwise.When the

highest speed has been found, turn the low speed needle L 1/

4 turn counter-clockwise.

The high speed jet H affects the engine power, speed,

temperature and fuel consumption. If the high speed jet H is

set too lean (screwed in too far) the engine speed will be too

high and cause engine damage. Do not let the engine run at

full speed for more than 10 seconds.

+ 1/4

CAUTION! If the sweeper rollers rotates/moves while the

engine is idling, the T-screw should be turned anti-clockwise

until the sweeper rollers stops.

Apply full throttle and turn the high speed jet H very slowly

clockwise until the engine slows down. Then turn the high

speed jet H very slowly anticlockwise until the engine starts to

run unevenly. Now turn the high speed jet H slowly clockwise

a little way until the engine runs smoothly.

Fine adjustment of the idle speed T

Adjust the idling speed with the T-screw, if it is necessary to

readjust. First turn the idle speed adjusting screw T clockwise

until the sweeper rollers starts to rotate/move.Then turn, anti-

clockwise until the sweeper rollers stops. A correctly adjusted

idle speed setting occurs when the engine runs smoothly in

every position. It should also be good margin to the rpm when

the sweeper rollers starts to rotate/move.

Note that the engine should be run unloaded when adjusting

the high speed needle. Therefore dismantle the sweeper

rollers and roller shafts before adjusting the high speed

needle.

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.

WARNING! If the idling speed cannot be

adjusted so that the sweeper rollers stops,

contact your service workshop. Do not use

the machine until it has been correctly

adjusted or repaired.

CAUTION! For optimum adjustment of the carburettor,

contact a qualiﬁed dealer/service workshop that has a

revolution counter at their disposal.

Correctly adjusted carburetor

When the carburetor is correctly adjusted the machine will

accelerate without hesitation and burble a little at maximum

speed. It is also important that the sweeper rollers does not

rotate/move at idle.

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.

MAINTENANCE

Mufﬂer

Cooling system

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.

To keep the working temperature as low as possible the

machine is equipped with a cooling system.

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.

The cooling system consists of:

Air intake on the starter.

Fins on the ﬂywheel.

Cooling ﬁns on the cylinder.

Cylinder cover (directs cold air over the cylinder).

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 catalytic converter the mesh should be

checked, and if necessary cleaned, monthly. If the mesh is

damaged it should be replaced.

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.

Angle gear

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 mufﬂer. A blocked mesh will cause

the machine to overheat and result in damage to the cylinder

and piston.

The angle gear is ﬁlled with a sufﬁcient quantity of grease at

the factory.

Normally, the grease does not need to be changed except

when repairs are carried out.

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!

MAINTENANCE

Air ﬁlter

Spark plug

The air ﬁlter must be regularly cleaned to remove dust and dirt

in order to avoid:

The spark plug condition is inﬂuenced by:

•

Incorrect carburetor adjustment.

•

Carburettor malfunctions

Starting problems

An incorrect fuel mixture (too much or incorrect type of

oil).

Loss of engine power

•

A dirty air ﬁlter.

Unnecessary wear to engine parts

Excessive fuel consumption.

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 0.5 mm (0,020"). The spark plug

should be replaced after about a month in operation or earlier

if necessary.

Clean the ﬁlter every 8 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.

CAUTION! Always use the recommended spark plug type!

Use of the wrong spark plug can damage the piston/cylinder.

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.

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.

IMPORTANT!

The sweeper is often used under dusty conditions. It is

extremely important to maintain the air ﬁlter regularly, often

daily. The air ﬁlter must be oiled in order to work

satisfactorily.

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 oil out of the ﬁlter inside the plastic bag and pour off

the excess before ﬁtting the ﬁlter to the machine. Never use

common engine oil. This would drain through the ﬁlter quite

quickly and collect in the bottom.
