ODUCTION

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 waterpowered 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

SAFETY INSTRUCTIONS

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.

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.

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.

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.

General working instructions

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.

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.

12 – English

1155849-49 Rev. 2 2013-03-22

SAFETY INSTRUCTIONS

• 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.

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.

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.

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.

• 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,

1155849-49 Rev. 2 2013-03-22

• CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

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.

• 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.

• 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.

• 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 HANDLING

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always been 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.

WARNING! Always ensure there is adequate ventilation when handling fuel.

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 socalled “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.

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.

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.

MAINTENANCE

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.

WARNING! Never use the blower if the screen is not in place. Before use, check

that the screen is in place and undamaged.

Spark plug

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

570, 580 - BTS, BFS

• Loosen the four fasteners holding the air ﬁlter cover and remove the ﬁlter. Wash the preﬁlter in warm soapy water.

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.

0,6-0,7

1155849-49 Rev. 2 2013-03-22

• 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.

MAINTENANCE

560BTS, BFS

Remove the air ﬁlter cover and take out the ﬁlter. Wash it clean in warm, soapy water.

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.

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.

must always be replaced.

• Reﬁt the air ﬁlter and air ﬁlter cover.

Oiling the air ﬁlter

560BTS, BFS

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.

A damaged air ﬁlter

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.
