Dear customer!

Cong

ratulations 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.

Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and

Vibration damping system

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.

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 screen 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

Stop switch

• 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 1157956-49 Rev. 2 2016-11-09

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 screen; this must be cleaned regularly. See

the heading Mufﬂer in the Maintenance chapter. A

blocked screen will cause the engine to overheat and

may lead to serious damage. Never use a mufﬂer with

a defective spark arrestor screen.

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. 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.

• 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.

• 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.

!

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

1157956-49 Rev. 2 2016-11-09

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.

• 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.

• 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 operator’s manual should warn that work from

ladders or high places (such as roofs) is prohibited

and 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.

SAFETY INSTRUCTIONS

12 – English 1157956-49 Rev. 2 2016-11-09

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.

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.

• 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! Don’t operate the blower if

the exhaust gas outlet on the engine

cover is covered by a wall and/or some

other obstacles, the machine could get

damage. Make sure that the distance is

50 cm or more from the obstacles during

operation.

!

WARNING! Always stop the engine

before cleaning.

FUEL HANDLING

14 – English 1157956-49 Rev. 2 2016-11-09

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).

•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.

• When working at continuous high revs a higher octane

rating is recommended. Use good quality unleaded

gasoline.

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.

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.

!

WARNING! Taking the following

precautions, will lessen the risk of ﬁre:

Refuel in a well ventilated area. Never

fuel the machine indoors.

Starting and stopping

Cold engine

Ignition: Set the stop switch to the start position.

Set the throttle adjuster to the start position, about one

third open.

1 Full throttle

2 About one third open.

3 Idle speed

4 Stop switch

Choke: Set the choke control in the choke position.

Air purge: Press the air purge repeatedly until fuel begins

Warm engine

Use the same starting procedure as for a cold engine but

without setting the choke control in the choke position.

Starting

Hold the body of the machine on the ground using your

left hand (CAUTION! Not with your foot!). Grip the starter

handle, slowly pull out the cord with your right hand until

you feel some resistance (the starter pawls grip), now

quickly and powerfully pull the cord. Never wrap the

starter cord around your hand

Repeat pulling the cord until the engine starts. When the

engine starts, return choke control to run position.

CAUTION! Do not pull the starter cord all the way out and

do not let go of the starter handle when the cord is fully

extended. This can damage the machine.

Air is released as soon as the engine is started, even

when idling. Do not allow anyone to stand close to the

blower or the blower tube.

Allow the engine to warm for a few minutes.

Stopping

The engine is stopped by moving the stop switch to the

stop position.

!

WARNING! Always move the machine

away from the refueling area and source

before starting. Place the machine on a

ﬂat surface.

Make sure no unauthorised persons are

in the working area, otherwise there is a

risk of serious personal injury. The safety

distance is 15 meters (50 ft.).

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.

General

Remove the ignition cable and the spark plug to carry out

inspection and maintenance. Keep all parts of your body

away from hot surfaces.

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.

The factory idle speed setting is: 2200 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

screen. The spark arrestor screen should be cleaned

once a month. This is best done with a wire brush.

To remove the spark arrestor screen proceed as follows:

• Remove the exhaust duct. (3)

• Remove the spark arrester. (2)

• Pull out the spark arrestor screen and clean using a

wire brush. Replace the spark arrestor screen if it is

defective.

• Remove any carbon deposits in the mufﬂer's inlet and

outlet and in the cylinder's exhaust port.

CAUTION! Never use a machine with a defective mufﬂer.

Check regularly that the mufﬂer is complete and secured

correctly. Tighten the screws. 8-12 Nm

Check that the spark arrester and the exhaust duct are

screwed in place correctly. (2) (3) 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.

!

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!

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 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.

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.

Check the airﬁlter and clean it when it´s necessary.

Avoid contact with hot surfaces on mufﬂer, cylinder etc.

Contact can result in burns to the skin.

Cleaning the air ﬁlter

•Remove the air ﬁlter cover and take out the ﬁlter. Wash

it clean in warm, soapy water.

• Reﬁt the air ﬁlter and air ﬁlter cover. Do not forget to

put the air screen back in place. If the grill is missing,

the air cleaner is not properly sealed, and dust can get

into the cylinder.

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.

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.

!

WARNING! Never use the blower if the

screen is not in place. Before use, check

that the screen is in place and

undamaged.

1157956-49 Rev. 2 2016-11-09

Oiling the air ﬁlter

Always use special ﬁlter oil. 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.

Shoulder strap

If the shoulder strap is damaged, it may break while in use

and the machine may fall causing personal injury. Follow

the instructions below to replace the shoulder strap.

1 Remove the clamp from the strap.

2 Run the end of the strap through the hanger.

3 Reﬁt the clamp to the strap.

!

WARNING! Check that the thick round

pin in the clamp is inserted in the strap. If

it is inserted incorrectly it may lead to

personal injury.
