INTR 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 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
′ manual as a valuable document. By following its
′ s
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.

SAFETY INSTRUCTIONS
General working instructions 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 naked 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 gas station to find out where to dispose of excess fuel.
• Ensure the machine is cleaned and that a complete service is carried out before long-term storage.
!
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and inhaling fumes.
Adjusting the harness
!
WARNING! 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.
A correctly adjusted harness and machine significantly facilitates the work. Adjust the harness to give the best working position.
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. 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.
• Observe your surroundings. Direct the blower away from people, animals, play areas, and cars etc.
• Clean up afterwards. Make sure that you have not blown rubbish into someone’s garden.
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.

Basic safety rules
SAFETY INSTRUCTIONS
Basic working techniques
• No unauthorised persons or animals may be present in the working area, which is 15 metres.
• The powerful currents of air can move objects at such a speed that they can bounce back and cause serious eye injuries.
!
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.
• The speed of the air jet is regulated by means of the throttle. Select the speed best suited for respective tasks.
(356 BT
X-SERIES
) 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• When work is finished the machine should be stored vertically.
• CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

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.
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.
!
Gasoline
WARNING! Always ensure there is adequate ventilation when handling fuel.
CAUTION! Always use high grade oil mixed gasoline
(minimum 87 RON).
• 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
•
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.
Two-stroke oil
• For best results and performance use HUSQVARNA twostroke 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.

MAINTENANCE
Carburetor
Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/service workshop
(who will have a rev counter at their disposal) to adjust your carburettor.
Function
The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine.
The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil.
The carburetor has three adjustment controls:
• L = Low speed jet
• H = High speed jet
• T = Idle adjustment screw
L
T
Conditions
• Before any adjustments are made, make sure that the air filter is clean and the air filter cover is fitted. If you adjust the carburettor when the air filter is dirty it will result in a leaner mixture when the filter is finally cleaned. This can lead to serious engine damage.
• Carefully turn both jets, L and H, so that they are midway between fully screwed in and fully screwed out.
• Do not attempt to adjust the L and H jets beyond either stop as this could cause damage.
• Now start the machine according to the starting instructions and let it warm up for 10 minutes.
Low speed jet L
If the engine run unstable on idle, adjest the L jet clockwise respectively anticlockwise until the engine runs smoothly.
Fine adjustment of the idle speed T
Adjust the idle speed screew T clockwise respectively anticlockwise until an idle speed of 2300 rpm is reached.
H
The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anticlockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed.
The T-screw regulates the throttle setting at idle speed. If the
T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.
Basic setting
The basic carburetor settings are adjusted during testing at the factory. The basic setting is richer than the optimal setting and should be maintained for the first few hours the machine is in use. The carburettor should then be finely adjusted. Fine adjustment should be carried out by a skilled technician.
Fine adjustment
When the machine has been ”run-in” the carburetor should be finely adjusted. The fine adjustment should be carried out
by a qualified person. First adjust the L-jet, then the idling screw T and then the H-jet.
High speed jet H
Apply full throttle. Adjust the H jet clockwise respectively anticlockwise until a racing speed of 5800-6000 rpm is reached and the engine runs smoothly.
Correctly adjusted carburetor
When the carburetor is correctly adjusted the machine will accelerate without hesitation and burble a little at maximum speed. If the low speed jet L is set too lean it may cause starting difficulties and poor acceleration.
If the high speed jet H is set too lean it will result in less power, less performance, poor acceleration and/or damage to the engine.
If both the L and H jets are set too rich it will results in acceleration problems or too low a working speed.

MAINTENANCE
Cooling system 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.
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of:
4
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 screws to the capillary tube and exhaust pipe.
Loosen the muffler’s 2 screws and remove the muffler.

3
5
1 Air intake on the underside of the blower.
2 Nozzle for cooling the cylinder
3 Cooling fins on the cylinder.
4 Cooling air conductor (directs cold air over the cylinder).
5 Emergency cooling nozzle
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.
Spark plug
Pull out the spark arrestor screen and clean using a wire brush. Replace the spark arrestor screen if it is defective.
CAUTION! Never use a machine with a defective muffler.
!
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!
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.
If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0.5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.

MAINTENANCE
The air filter is fitted in the air filter cowling.
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.
Ensure that the filter is soaked in oil before refitting it.
Avoid contact with hot surfaces on muffler, cylinder etc.
Contact can result in burns to the skin.
Cleaning the air filter
Dismantle the outer cover with the help of the four fasteners holding the outer cover.
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.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 60-76. The 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.
Loosen the two fasteners holding the air filter cowling and remove the filter. Wash the filter clean in warm, soapy water.

FEDERAL AND CALIFORNIA EMISSIONS CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND
OBLIGATIONS
The EPA (U.S. Environmental Protection Agency), CARB
(California Air Resources Board), Environment Canada and
Husqvarna Forest & Garden are pleased to explain the emissions control system’s warranty on your 2009 and later small off-road engine. In U.S. and Canada, new equipment that use small off-road engines must be designed, built, and equipped to meet the applicable Federal or Californian stringent anti-smog standards. Husqvarna Forest & Garden must warrant the emissions control system on your small offroad engine for the period listed below provided there has been no abuse, neglect or improper maintenance of your equipment. Your emissions control system may include parts such as the carburetor, ignition system, catalytic converter, fuel tank, filters and other associated components. Also, included may be hoses, belts, connectors, sensors, and other emission-related assemblies. Where a warrantable condition exists, Husqvarna Forest & Garden will repair your small offroad engine at no cost to you including diagnosis, parts and labor.
MANUFACTURER
′′′′S WARRANTY
COVERAGE
The emissions control system is warranted for two years. If any emissions-related part on your equipment is defective, the part will be repaired or replaced by Husqvarna Forest &
Garden.
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.
• As the small off-road engine owner, you should however be aware that Husqvarna Forest & Garden may deny you warranty coverage if your small off-road engine or a part has failed due to abuse, neglect, or improper maintenance or unapproved modifications.
• You are responsible for presenting your small off-road engine to a Husqvarna Forest & Garden distribution center or service center as soon as the problem exists.
The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have any questions regarding your warranty rights and responsibilities, you should contact your nearest authorized servicing dealer or call Husqvarna Forest &
Garden at 1-800-487-5951 or visit www.usa.husqvarna.com.
WARRANTY COMMENCEMENT DATE
The warranty period begins on the date the engine or equipment is delivered to an ultimate purchaser.
LENGTH OF COVERAGE
Husqvarna Forest & Garden warrants to the ultimate purchaser and each subsequent owner that the engine or equipment is designed, built, and equipped so as to conform with all applicable regulations adopted by EPA and CARB, and is free from defects in materials and workmanship that causes the failure of a warranted part for a period of two years.
WHAT IS COVERED
REPAIR OR REPLACEMENT OF PARTS Repair or replacement of any warranted part under the warranty must be performed at no charge to the owner at a warranty station.
Warranty services or repairs will be provided at all Husqvarna
Forest & Garden distribution centers that are franchised to service the subject engines. Throughout the emissions warranty period of two years, Husqvarna Forest & Garden must maintain a supply of warranted parts sufficient to meet the expected demand for such parts.
WARRANTY PERIOD Any warranted part that is scheduled for replacement as required in the maintenance schedule, is warranted for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first scheduled replacement, the part will be repaired or replaced by Husqvarna Forest & Garden at no cost. Any such part repaired or replaced under warranty is warranted for the remainder of the period prior to the first scheduled replacement point for the part. Any warranted part that is not scheduled for replacement as required in the maintenance schedule, is warranted for two years. If any such part fails during the period of warranty coverage, it will be repaired and replaced by Husqvarna Forest & Garden at no cost. Any such part repaired or replaced under the warranty is warranted for the remaining warranty period. Any warranted part that is scheduled only for regular inspection in the maintenance schedule will be warranted for a period of two years. A statement in such written instructions to the effect of ”repair or replace as necessary” will not reduce the period of warranty coverage. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.
DIAGNOSIS The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective, provided that such diagnostic work is performed at a warranty station.
