❗ 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.
- 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.
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.
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! 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.
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.
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
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.
⚠️ WARNING! Always ensure there is adequate ventilation when handling fuel.
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 ratio: 50:1 (2%) with HUSQVARNA two-stroke oil.
| Gasoline, litre | Two-stroke oil, litre 2% (50:1) | US gallon | US fl. oz. |
|---|---|---|---|
| 5 | 0.10 | 1 | 2 1/2 |
| 10 | 0.20 | 2 1/2 | 6 1/2 |
| 15 | 0.30 | 4 | 12 7/8 |
| 20 | 0.40 | 5 | - |
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.

- 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.
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
Starting and Stopping (570, 580 - BTS, BFS)
⚠️ 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.).

560, 570, 580 - BFS: The engine is stopped by switching the ignition off using the stop switch.
Maintenance
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.
⚠️ 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!
Check that the spark arrester and the exhaust duct are screwed in place correctly (5). Tighten to 2-3 Nm.
To remove the spark arrestor screen proceed as follows:
- Remove the exhaust duct (4, 5).
- Remove the spark arrestor (3).
- 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. (1), (2) Tighten the screws. 8-12 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.
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.
0.6-0.7
? 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. Allow the filter to dry. Replace if necessary.
- Replace the paper filter with new one in case it has been contaminated.
? NOTE! The air filter must not be cleaned or blown clean with compressed air. This will damage the filter. Do not oil the filters.
Do not use oleaginous solvent to clean the pre filter.
Do not clean a paper filter by striking it with or against another object. The filter may be damaged and resultant dust contamination can diminish engine performance.
Cleaning the air 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.
- Remove the clamp from the strap.
- Run the end of the strap through the hanger.
- 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.
