• Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-stroke oil).
• Avoid all skin contact with fuel. Fuel is a skin irritant and may even cause skin changes.
• Move the machine at least 3 m from the refuelling point before starting it.
  
• Never start the machine:
  • If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate.
  • If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.
  • If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

Transport and storage

• Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or open flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers.
• When storing and transporting fuel always use approved containers intended for this purpose.
• When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to find out where to dispose of excess fuel. Empty the fuel tank and press the primer until all fuel has been emptied. Remove the spark plug and drop a spoon of 2-stroke oil in the cylinder. Turn over the engine a few times and then put the spark plug back in place.
• Ensure the machine is cleaned and that a complete service is carried out before long-term storage.
• Secure the machine during transport.
• Store the machine in a dry, cool, well-aired and dustfree location. Store the machine out of reach of children.

Take care when handling fuel. Bear in mind the risk of fire, explosion and inhaling fumes.

Adjusting the harness

The harness must always be worn when working with the machine. Failure to do so means you will be unable to manoeuvre safely and this can result in injury to yourself or others.
Make sure that the waist belt and chest belt are buttoned and correctly adjusted.
There is a risk that an unclosed belt can get stuck or sucked into the fan of the machine.

A correctly adjusted harness and machine significantly facilitates the work. Adjust the harness to give the best working position.

Tighten the side straps so that the pressure is evenly distributed across the shoulders.

Place the hip strap over the hip and not too far down on the stomach. Tighten the hip strap so that you feel the weight of the blower resting on your hip. Tighten and adjust the breast belt for the best working position.

SAFETY INSTRUCTIONS

Machine's safety equipment

This section describes the machine's safety equipment, its purpose, and how checks and maintenance should be carried out to ensure that it operates correctly. See the "What is what" section to locate where this equipment is positioned on your machine.

Never use a machine that has faulty safety equipment! Carry out the inspection, maintenance and service routines listed in this section.

Stop switch

Use the stop switch to switch off the engine.
Remove the ignition cable and the spark plug to carry out inspection and maintenance.

Vibration damping system

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

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 mesh 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.

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!

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.
  

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 mesh; this must be cleaned regularly. See the heading Muffler in the Maintenance chapter. A blocked mesh will cause the engine to overheat and may lead to serious damage. Never use a muffler with a defective spark arrestor mesh.

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

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. Reduce the noise levels by limiting the number of equipment units used simultaneously. 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. 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.
• Use the machine during normal working hours to avoid unnecessary noise. Avoid working early in the morning or late at night.

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.
• 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, or in high places (such as roofs). Their work could result in severe injury.
  
• 
  Do not use the machine unless you are able to call for help in the event of an accident.

Basic working techniques

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.

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.

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 pipe 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. Intermediate pipe
  5. Standard nozzle
  6. Control handle
  7. Knob

NOTE! Lubricate the pipes a little to facilitate assembly.

• Remove the knob from the handle holder (1), align the handle holder with the convex of the control pipe. Fasten the handle holder to the control pipe and replace the knob.
  
• Adjust the position and angle to achieve a comfortable working position, and tighten.
• Use the clamp to fasten the cabling to the flexible hose.

Assemble the intermediate pipe.

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

FUEL HANDLING

Fuel

The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol and two-stroke 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.

Always ensure there is adequate ventilation when handling fuel.

Petrol

Always use a good quality petrol/oil mixture (at least 90 octane).

• When working at continuous high revs a higher octane rating is recommended. Use good quality unleaded petrol.
• The lowest recommended octane rating is 90. If you run the engine on a petrol with a lower octane rating than 90 this can cause knocking. This leads to an increased engine temperature, which can result in serious engine damage.

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
  1:50 (2%) with HUSQVARNA two-stroke oil.

Petrol, litre	Two-stroke oil, litre
	2% (1:50)
5	0,10
10	0,20
15	0,30
20	0,40

Mixing

• Always mix the petrol and oil in a clean container intended for fuel.
• Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.
• 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.

Fueling

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 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

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 meters.
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.

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

It is not allowed to set the stop switch in full throttle position.

Choke: Set the choke control in the choke position.
Primer bulb: Press the air purge repeatedly until fuel begins to fill the bulb. The bulb need not be completely filled.

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 twist the starter cord around your hand.

Repeat pulling the cord until the engine starts. When the engine starts, return choke control to run position.

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.

NOTE!
Air is released as soon as the engine is started, even when idling.
When the engine fails to start after several attempts due to overchocking, open the choke and repeat pulling the rope.

Set the required engine speed with the throttle control.

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.

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.

Carburettor

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

To remove the spark arrestor mesh proceed as follows:

• Remove the exhaust duct (4, 5).
• Remove the spark arrester (3).
• Pull out the spark arrestor mesh and clean using a wire brush. Replace the spark arrestor mesh if it is defective.
• Remove any carbon deposits in the muffler's inlet and outlet and in the cylinder's exhaust port.

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

Check that the spark arrester and the exhaust duct are screwed in place correctly (5). Tighten to 2-3 Nm.

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.

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.

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 carburettor 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.

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

• Loosen the four fasteners holding the air filter cover and remove the filter.
  
• Wash the prefilter in warm soapy water. After cleaning, rinse the filter well in clean water. Squeeze out and allow the filter to dry. Replace if necessary.
• Replace the paper filter with new one in case it has been contaminated.
  
  1. Air filter cover
  2. Prefilter
  3. Paper filter
• Refit the air filter and air filter cover.
• NOTE! The air filter must not be cleaned or blown clean with compressed air. This will damage the filter. Do not oil the filters.
• Never 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.

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.

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.
