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.

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. These
symptoms may be increased in cold
temperatures. In order to reduce the risk
of whitefinger disease, the following
precautions are strongly recommended.
Wear thick anti-vibration gloves.
Take more than 5 minutes of break in
warm place frequently.
Maintain a firm grip at all times, but do
not squeeze the handles with constant,
excessive pressure.
If you feel discomfort, redness and
swelling of your fingers or any other part

Vibration damper
Your machine is equipped with a vibration damping
system that is designed to reduce 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.
A muffler fitted with a catalytic converter is also designed
to reduce harmful exhaust gases.
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 screen. Check whether the muffler on
your machine is fitted with this kind of screen.
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.
Regularly check that the muffler is securely attached to
the machine.
!
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.
SAFETY INSTRUCTIONS
10 – English
If the muffler on your machine is fitted with a spark
arrestor screen this must be cleaned regularly. A blocked
screen will cause the engine to overheat and may lead to
serious damage.
NOTE!
Make sure that the spark arrestor is screwed in place
correctly.
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.
!
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!
!
WARNING! The inside of the muffler
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.

FUEL HANDLING
12 – English
Fuel
CAUTION! The machine is equipped with a two-stroke
engine and must always be 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.
Gasoline
CAUTION! Always use high grade oil mixed gasoline
(minimum 87 RON).
When working at continuous high revs a higher octane
rating is recommended. Use good quality unleaded
gasoline.
This engine is certified to operate on unleaded
gasoline.
The lowest recommended octane rating is 87. If you
run the engine on lower octane rating than 87 so-
called “knocking“ can occur. This leads to an
increased engine temperature, which can result in a
serious engine breakdown.
Husqvarna alkylate fuel
Husqvarna recommends the use of Husqvarna alkylate
fuel for best performance. Husqvarna alkylate fuel is not
available in all markets.
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 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.
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 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.
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.
This engine is certified to operate on unleaded
gasoline.
!
WARNING! Always ensure there is
adequate ventilation when handling fuel.

Fueling
Move the machine at least 10 ft (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.
Keep the handle dry and free from oil and fuel.
Always store fuel in an approved container designed
for that purpose.
!
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
refueling.
Always stop the engine and let it cool for
a few minutes before refueling.
When refuelling, open the fuel cap slowly
so that any excess pressure is released
gently.
Tighten the fuel cap carefully after
refueling.
If you have spilled fuel on it. Wipe off the
spillage and allow remaining fuel to
evaporate.
Always move the machine away from the
refueling area and source before
starting.

WORKING TECHNIQUES
16 – English
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. To reduce
sound levels, limit the number of pieces of equipment
used at any one time. Read through and follow the simple
directions so that you disturb your surroundings as little as
possible.
This blower is a hand held type. The blower is held
using the handle by hand. It is operated and controlled
by the handle while operating. 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.
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.
Operate power equipment only at reasonable hours,
not early in the morning or late at night when people
might be disturbed. Comply with times listed in local
ordinances.
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 refueling.
Keep all parts of your body away from hot surfaces.
Never touch the spark plug or ignition cable while the
engine is running. Touching the spark plug or plug
may result in being subjected to an electrical shock.
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.
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.
D
!
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.
WORKING TECHNIQUES
English 17
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.
Conserve water by using power blowers instead of
hoses for many lawn and garden applications,
including areas such as gutters, screens, patios, grills,
porches and gardens.
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
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 throttle position
settings 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.
Use the full blower nozzle extension so the air stream
can work close to the ground.
Always check to be sure that no debris has been
blown onto someone else’s property.
Never point a blower tube toward an open flame to
avoid the possibility of igniting the unit, causing injury
to yourself or damage to surroundings.
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.
MAINTENANCE
18 – English
Carburetor
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. Adjust the idle
speed using the idle adjustment screw T, if it is necessary
to readjust.
Recommended idle speed: See the Technical data
section.
Muffler
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.
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 arrestor
screen. If your machine has this type of muffler, you
should clean the screen at least once a week. This is best
done with a wire brush. On mufflers without a catalytic
converter the screen should be cleaned weekly, or
replaced if necessary. On mufflers fitted with a catalytic
converter the screen should be checked, and if necessary
cleaned, monthly. If the screen is damaged it should be
replaced. If the screen 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 screen will cause the machine to overheat and
result in damage to the cylinder and piston.
CAUTION! Never use a machine with a defective muffler.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
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.
Spark plug
The spark plug condition is influenced by:
Incorrect carburetor 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,

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!

clean it and check that the electrode gap is 0,026 inch
(0,65 mm). The spark plug should be replaced after about
a month in operation or earlier if necessary.
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.
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.
1 Foam plastic filter (urethan filter)
2 Felt filter
3 Screen
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Close the choke control by setting the choke into a choke
position.
Remove the air filter cover and take out the filter. Wash
it clean in warm, soapy water. Clean also the inside of
the filter cover by using air or a brush. Ensure that the
filter is dry before refitting it.
Remove the Felt filter from the filter holder and gently
brush debris from the filter.
Install screen and Felt filter to the air filter holder.
Install the foam filter in the air filter cover.
Install the air filter 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. Damaged, very dirty, or fuel-
soaked air filter must always be replaced.
Air intake screen
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.
Fuel filter
Check the fuel filter for contamination and the fuel hose
for cracks or other defects. Replace if necessary.

screen is not in place. Before use, check
that the screen is in place and
undamaged.
