INTRODUCTION
1157401-38 Rev.1 2014-11-18
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 Husqvarna 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 the more than 300 years of beeing, 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. The business concept is to develop, manufacture and market motor driven products for forestry and
gardening as well as for building and construction industry. Husqvarna′s aim is also to be in the front edge according to
ergonomics, usability, security and environmental protection.That is the reason why we have developed many different
features to provide our products within these areas.
We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very
long time to come. The purchase of one of our products 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 authorised dealers, ask for the
address of your nearest service workshop.
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 will sell this machine, make sure that the buyer will get
the operator′s manual.
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.

General working instructions
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.
• Hold the opening of the blower as close to the ground
as possible. Utilise the entire length of the blow pipe
to keep the air current close to the ground.
• Clean up afterwards. Make sure that you have not
blown rubbish into someone’s garden.
Basic safety rules
• No unauthorised persons or animals may be present
in the working area, which is 15 metres.
• Allow the engine to cool before refuelling.
• Keep all parts of your body away from hot surfaces.
• If the machine catches fire or other emergency occurs
which forces you to release yourself from the
machine, open the harness straps and let the
machine fall backwards.

!
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.
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.
!
WARNING! Be aware of 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, open
windows and cars etc.

SAFETY INSTRUCTIONS
English – 11
1157401-38 Rev.1 2014-11-18
• The powerful currents of air can move objects at such
a speed that they can bounce back and cause serious
eye injuries.
• Do not direct the air jet towards people or animals.
• 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.
• Minimise the blowing time by lightly wetting dusty
areas or using spray equipment.
• 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.
• 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.
Basic working techniques
• This blower is a backpack type, and is carried using a
shoulder harness while operating. It is operated and
controlled with the handle on the tube using the right
hand.
• 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.
• Keep a good balance and a firm foothold.
• When work is finished the machine should be stored
vertically.
!
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.

FUEL HANDLING
English – 13
1157401-38 Rev.1 2014-11-18
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.
Petrol
CAUTION! Always use a good quality petrol/oil mixture (at
least 90 octane).
• 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. Use good quality unleaded petrol.
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.
Mixing
• Always mix the petrol and oil in a clean container
intended for fuel.
• 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.
• 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
• Move the machine at least 3 m from the refuelling
point before starting it.
• 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 filling the tank.

MAINTENANCE
English – 15
1157401-38 Rev.1 2014-11-18
General
Keep all parts of your body away from the hot surfaces.
The ignition lead should always be removed from the
spark plug before repair, cleaning or maintenance work.
Carburettor
Adjustment of the idle speed
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
The factory idle speed setting is 2,000 rpm. Use the
adjustment screw at the upper edge of the carburettor if
the idle speed has to be adjusted.
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.
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 exhaust duct.
• Remove the spark arrester.
Pull out the spark arrestor mesh and clean using a wire
brush. Replace the spark arrestor mesh if it is defective.
CAUTION! Never use a machine with a defective muffler.
Check regularly that the muffler is complete and secured
correctly. (1,2). Tighten the screws, 8-10Nm.
Check that the spark arrester and the exhaust duct are
screwed in place correctly (5).Tighten to 2-3 Nm.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
• Cooling fins on the cylinder.
• Air intake screen
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.
Air intake screen
Check that the air intake is not blocked on all sides
including the underside, 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.

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.
Clean the outside of the spark plug. Remove it and check
the electrode gap. Adjust the gap to 0,6-0,7 mm or
replace the spark plug. Check that the spark plug is fitted
with a suppressor.
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 40 hours, or more regularly if
conditions are exceptionally dusty.
Avoid contact with hot surfaces on muffler, cylinder etc.
Contact can result in burns to the skin.
Cleaning the air filter
• Loosen the four quick-action clips and lift off the cover
and remove the filter.Wash the prefilter in warm soapy
water.
• Tap the paper filter against a hard surface to shake off
the dust. If the paper filter is still dirty it should be
replaced with a new one.
NOTE!
Do not oil the filter.
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.

TECHNICAL DATA
1157401-38 Rev.1 2014-11-18
Technical data
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.
