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.

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.

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.

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.

Checking, maintaining and servicing the machine's safety equipment

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.

Stop switch

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

SAFETY INSTRUCTIONS

The engine is stopped by switching the ignition off using the stop switch.

Vibration damping system

• Check the vibration damping units regularly for cracks or deformation. Replace them if damaged.

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 arrester 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 arrester screen.

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.

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

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.

• 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.

• 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 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.

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 15m . 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.

• 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.

ASSEMBLY

Assembling the blow pipe and control handle

• Connect the blower and control pipe with the flexible hose. Clamp both ends of the flexible hose in place. Use the accompanying hardware.

1 Flexible hose
2 Control pipe
3 Clamp
4 Clamp

NOTE!

Lubricate the pipes a little to facilitate assembly.

• Fasten the handle holder to the control pipe and tighten the knob on the holder. Please make sure to align the handle holder with the convex of the control pipe.

• Adjust the position and angle to achieve a comfortable working position, and tighten.

• Use the clamp to fasten the cabling to the flexible hose. (BTS)

• Connect the straight pipe and pipe end. Push the pipes together and turn them so they lock.

Accessories

Handlebar

Assemble the intermediate pipe.

• If higher air speed is required, the round blow pipe is replaced by the flat nozzle.

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 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.

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.

Gasoline, litre Two-stroke oil, litre
	2% (1:50)
5 0,10
10 0,43/0,20
15 0,6/0,30
20 0,40
US gallon US fl. oz.
1 2 1/2
2 1/2 6 1/2
5 12 7/8

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

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.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.

Always move the machine away from the refuelling area and source before starting.

• 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.

Starting and stopping

WARNING! Always move the machine away from the refuelling 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 metres.

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.

Cold engine

Ignition: Set the stop switch to the start position. About one third open.

Allow the engine to warm for a few minutes.

1 Full throttle
2 About one third open.
3 Idle speed
4 Stop switch

Stopping

The engine is stopped by moving the stop switch to the stop position.

The engine is stopped by switching the ignition off using the stop switch.

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 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 screen. The spark arrestor screen should be cleaned once a month. This is best done with a wire brush.

To remove the spark arrester screen proceed as follows:

• Remove the exhaust duct (4).
• Remove the spark arrester (3).
• Pull out the spark arrester screen and clean using a wire brush. Replace the spark arrester screen 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.

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!

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.

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

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.

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.

• 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.

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. A damaged air filter 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.

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.

OWNER'S WARRANTY RESPONSIBILITIES

• As the small off-road engine owner, you are responsible for performance of the required maintenance listed in your operator's manual. Husqvarna Forest & Garden recommends that you retain all receipts covering maintenance on your small off-road engine, but Husqvarna Forest & Garden cannot deny warranty solely for the lack of receipts or your failure to ensure the performance of all scheduled maintenance.
