WARNING! Bear in mind that:
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
!
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!
The machine’s vibration damping system reduces the transfer
of vibrations.
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! Overexposure to vibration can
lead to circulatory damage or nerve damage
in people who have impaired circulation.
!
Checking,maintaining and servicing
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.

General working instructions
IMPORTANT! This section considers basic safety rules
when working with blowers. 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.
Show consideration to persons in your surroundings by
avoiding using the machine at unsuitable times, such as late
in the evening or early in the morning. Read through and
follow the simple directions so that you disturb your
surroundings as little as possible.
•
Use the blower with the lowest possible throttle. It is
seldom necessary to use full throttle, and many work
procedures can be done at half throttle. A lower throttle
means less noise and less dust, and it is also easier to
keep control over the rubbish collected together/moved.

SAFETY INSTRUCTIONS
•
•
•
Use a rake or a brush to release rubbish stuck to the
ground.
Basic working techniques
•
Adjust the harness so that the machine is easy to carry.
Hold the opening of the blower as close to the ground as
possible.
WARNING! Watch out for thrown objects.
Observe your surroundings. If anyone approaches your
work area, set the throttle control to the lowest throttle until
the person is at a safe distance. Direct the blower away
from people, animals, play areas, and cars etc.
Always wear eye protection. 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 10
m. Stop the machine immediately if anyone
approaches.
•
Clean up afterwards. Make sure that you have not blown
rubbish into someone’s garden.
Basic safety rules
WARNING! Always stop the engine before
cleaning.
!
•
•
No unauthorised persons or animals may be present in
the working area, which is 10 metres.
•
The speed of the air jet is controlled with the throttle.
Select the speed that best suits the application. To avoid
holding your finger on the throttle all the time when using
the blower, the required throttle can be set with the throttle
adjuster (D). Full throttle is obtained when the throttle
adjuster is pushed in fully.
The powerful currents of air can move objects at such a
speed that they can bounce back and cause serious eye
injuries.
D
C
•
•
Do not direct the air jet towards people or animals.
•
Make sure that the air intake is not blocked by leaves or
rubbish. This will reduce the machine’s air blowing
capacity and increase the engine’s working temperature,
which can lead to engine failure. Stop the engine and
remove the object.
Stop the engine before assembling or dismantling
accessories or other parts.
•
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.
•
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.
•
•
Never put the machine down with the engine running
unless you have it in clear sight.
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.
•
•
Be aware of the wind direction. Work with the wind to
make your work easier.
Using the blower to move large piles is time consuming
and creates unnecessary noise.
•
The blower must not be used while on a ladder or
scaffolding.
•
CAUTION! Do not use the machine unless you are able to
call for help in the event of an accident.

FUEL HANDLING
Mixing
Fuel
•
Always mix the petrol and oil in a clean container intended
for 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.
•
Always start by filling 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 filling the
machine’s fuel tank.
WARNING! Always ensure there is adequate
ventilation when handling fuel.
!
Petrol
CAUTION!
Always use a good quality petrol/oil mixture (at least 90
octane).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 and it will no longer serve its purpose.
•
•
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.
Fuelling
•
•
The lowest recommended octane rating is 90. If you run
the engine on a petrol with a lower octane rating than 90
this can cause knocking. This leads to an increased
engine temperature, which can result in serious engine
damage.
WARNING!Taking the following precautions,
will lessen the risk of fire:
!
When working at continuous high revs a higher octane
rating is recommended.
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
Two-stroke oil
Always stop the engine and let it cool for a
few minutes before refuelling.
•
For best results and performance use HUSQVARNA two-
stroke oil, which is specially formulated for our two-stroke
engines. Mixture 1:50 (2%).
When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
•
If HUSQVARNA two-stroke oil is not available, you may
use another two-stroke oil of good quality that is intended
for air cooled engines.Contact your dealer when selecting
an oil. Mixing ratio 1:33 (3%).
Tighten the fuel cap carefully after refuelling.
Always move the machine away from the
refuelling area before starting.
•
•
Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard oil.
•
Move the machine at least 3 m from the refuelling point
before starting it.
Never use oil intended for four-stroke engines.

MAINTENANCE
with a catalytic converter the screen should be checked and
Carburettor
cleaned monthly. If the screen is damaged it should be
replaced. If the screen is frequently blocked, this can be a
sign that the function of the catalytic converter is impaired.
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.
WARNING!The machine may only be started
in its complete design. If the machine is

started without all the guards fitted there is a
risk of personal injuries.
Cooling system
Function
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
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.
Fine adjustment of the idle speed T
The cooling system consists of:
Adjust the idle speed using the idle adjustment screw T, if it is
necessary to readjust.

4
Air intake on the starter.
Fins on the flywheel.
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. The idle
speed is correctly adjusted when the engine will run smoothly
in every position.
Cooling fins on the cylinder.
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.
Rec. idle speed See the Technical data section.
Muffler
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 arrest
screen. If your machine is fitted with this type of screen it
should be cleaned regularly. This is done using a wire brush.
On mufflers without a catalytic converter the screen should be
cleaned weekly, or replaced if necessary. On mufflers fitted

MAINTENANCE
Cleaning the air filter
Spark plug
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.
The spark plug condition is influenced by:
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.
•
•
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type of
oil).
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.
•
A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
Oiling the air filter
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 0.5/0,6 mm. The spark plug should
be replaced after about a month in operation or earlier if
necessary.
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.
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.
