Stop the engine before assembling or dismantling
accessories or other parts.
General working instructions
•
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.
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.
•
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.
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.
•
•
•
•
Use a rake or a brush to release rubbish stuck to the
ground.
•
•
Never put the machine down with the engine running
unless you have it in clear sight.
Hold the opening of the blower as close to the ground
as possible.
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.
Observe your surroundings. Direct the blower away
from people, animals, play areas, and cars etc.
•
The blower must not be used while on a ladder or
scaffolding.
Clean up afterwards. Make sure that you have not
blown rubbish into someone’s garden.

SAFETY INSTRUCTIONS
Basic working techniques
WARNING! Watch out for thrown objects.
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 15 m. Stop the machine
immediately if anyone approaches.
WARNING! Always stop the engine
before cleaning.
!
•
The speed of the air jet is regulated by means of the
throttle. Select the speed best suited for respective
tasks.You can set the throttle position using the ”stop
switch” and by doing so not need to hold your finger
on the throttle all the time you are using the blower.
Full throttle is obtained when the control is held back
fully.
•
Check that the air intake is not blocked, for example,
by leaves or rubbish. A clogged air intake reduces the
machine’s blowing capacity and increases the
engine’s working temperature, which can result in
engine failure. Stop the engine and remove the object.
•
•
•
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.
When work is finished the machine should be stored
vertically.

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 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).
•
•
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.
•
•
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.
When working at continuous high revs a higher octane
rating is recommended.
Two-stroke oil
•
For best results and performance use HUSQVARNA
two-stroke oil, which is specially formulated for our
two-stroke engines. Mixture 1:50 (2%).
•
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%).
•
•
Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard
oil.
Never use oil intended for four-stroke engines.

MAINTENANCE
Adjustment of the idle speed
Carburettor
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
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.
Adjust the idle speed screew T clockwise respectively
anti-clockwise until an idle speed of 2300 rpm is reached.
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.
Muffler
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.
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 carburettor has three adjustment controls:
•
•
•
L = Low speed jet
H = High speed jet
T = Idle adjustment screw
T
L
H
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 muffler is equipped with a special spark arrestor
mesh. The spark arrestor mesh should be cleaned once
a month. This is best done with a wire brush.
To remove the spark arrestor mesh proceed as follows:
Remove the screws to the capillary tube and exhaust
pipe.
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
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.

MAINTENANCE
Loosen the muffler’s 2 screws and remove the muffler.

Emergency cooling nozzle
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.Check that the nozzles
are not blocked.
Spark plug
Pull out the spark arrestor mesh and clean using a wire
brush. Replace the spark arrestor mesh if it is defective.
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 any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0.5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary.
CAUTION! Never use a machine with a defective muffler.
WARNING! The muffler gets 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.
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder.

conditions are exceptionally dusty.
Ensure that the filter is soaked in oil before refitting it.
Avoid contact with hot surfaces on muffler, cylinder etc.
Contact can result in burns to the skin.
Cleaning the air filter
Dismantle the outer cover with the help of the four
fasteners holding the outer cover.
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.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 60-76.
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.
Loosen the two fasteners holding the air filter cowling and
remove the filter. Wash the filter clean in warm, soapy
water.

Note 1: Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/
EC. Reported sound power level for the machine has been measured with the original cutting attachment that gives the
highest level.The difference between guaranteed and measured sound power is that the guaranteed sound power also
includes dispersion in the measurement result and the variations between different machines of the same model
according to Directive 2000/14/EC.
Note 2: The equivalent sound pressure level value is calculated with a work cycle of a duration of 1/7 for idling and 6/7
for racing. Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion
(standard deviation) of 1 dB(A).
Note 3:The equivalent vibration level value is calculated with a work cycle of a duration of 1/7 for idling and 6/7 for racing.
Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s2.
