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 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 in existence, 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 the building and construction industry. Husqvarna ′ s aim is also to be at the front edge for
ergonomics, usability, security and environmental protection.That is the reason why we have developed many different
features to add to 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 (usage, service, maintenance, etc), the life span and
the second-hand value of the machine can be extended. If you sell this machine, make sure that the operator ′ s manual
is passed on to the buyer.
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.

Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
In countries that have a warm and dry climate there is a
significant risk of fire. Consequently, we have equipped
the muffler with a spark arrestor mesh mounted inside the
muffler.
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine. See instructions under the heading Checking,
maintaining and servicing the machine’s safety
equipment.
Checking, maintaining and
servicing the machine ′ s safety
equipment

• Start the engine and make sure the engine stops
when you move the stop switch to the stop setting.
!
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!
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.
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!
!
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! 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.

SAFETY INSTRUCTIONS
10 – English
Vibration damping system
• Check the vibration damping units regularly for cracks
or deformation. Replace them if damaged.
• Check that the vibration damping element is
undamaged and securely attached.
Muffler
• Never use a machine that has a faulty muffler.
• Regularly check that the muffler is securely attached
to the machine.
• The muffler on your machine is equipped with a spark
arrestor mesh; this must be cleaned regularly. See the
heading Muffler in the Maintenance chapter. A
blocked mesh will cause the engine to overheat and
may lead to serious damage.Never use a muffler with
a defective spark arrestor mesh.
Air filter
Never use the leaf blower without an air filter or with a
damaged or deformed filter element as unfiltered, dusty
air can quickly destroy the engine.
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. Reduce the
noise levels by limiting the number of equipment units
used simultaneously. 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. Dispose of
debris in trash receptacles.
• Use the machine during normal working hours to
avoid unnecessary noise. Avoid working early in the
morning or late at night.

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.
• 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.
• Reduce water consumption by using blowers instead
of water hoses for different applications around the
lawn and garden, such as lattices, screens, grills,
porches, etc
• 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, or in high places (such as roofs).Their
work could result in severe injury.
• 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.
!
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.

SAFETY INSTRUCTIONS
12 – English
• 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.

FUEL HANDLING
14 – English
Fuel
CAUTION! The machine is equipped with a two-stroke
engine and must always be 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.
Ethanol blended fuel, E10 may be used (max 10%
ethanol blend). Using ethanol blends higher than E10 will
create lean running condition which can cause engine
damage.
Two-stroke oil
• For the best results and performance use
JONSERED two-stroke oil, which is specially
formulated for our two-stroke engines. Mixture 1:50
(2%).
• If JONSERED 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.
!
WARNING! Always ensure there is
adequate ventilation when handling fuel.

Fueling
• 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.
• Check the fuel level before each use and leave space
for the fuel to expand, because the heat from the
engine and the sun may otherwise cause the fuel to
expand and overflow.
!
WARNING! Taking the following
precautions, will lessen the risk of fire:
Refuel in a well ventilated area. Never
fuel the machine indoors.
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.

• 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
• Unscrew 2 knobs bolts and remove the air cleaner
cover.
• Remove the pre-filter and paper filter from the air filter
unit.
1 Air filter cover and knob bolt
2 Prefilter
3 Paper filter
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.
• Refit the air filter and air filter cover.
!
WARNING! Never use the blower if the
screen is not in place. Before use, check
that the screen is in place and
undamaged.
