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 Husqvarna 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 the more than 300 years in existence, 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. The business concept is to develop, manufacture and market motor-driven products for forestry and gardening, as well as for the building and construction industry. Husqvarna's aim is also to be at the front edge for ergonomics, usability, security and environmental protection. That is the reason why we have developed many different features to add to our products within these areas.

We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very long time to come. The purchase of one of our products 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 authorised dealers, ask for the address of your nearest service workshop.

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 (usage, service, maintenance, etc), the life span and the second-hand value of the machine can be extended. If you sell this machine, make sure that the operators manual is passed on to the buyer.

Thank you for using a Husqvarna product.

WORKING TECHNIQUES

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. Working with blowers is recommended for leaves or small branches only.

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. Make sure local regulations and ordinances are followed. 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.
• Minimise the blowing time by lightly wetting dusty areas or using spray equipment.
• Be aware of the wind direction. Work with the wind to make your work easier.
• If the machine starts vibrating abnormally, stop the machine and remove the batteries.
  • Using the blower to move large piles is time consuming and creates unnecessary noise.
• Clean up afterwards. Make sure that you have not blown rubbish into someone's garden.
• Walk with the machine, do not run.

Basic safety rules

- 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.

Illustration of a person using a chainsaw to spray or spray near a display board (no text or symbols present)

• 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.

• Do not overreach. Keep proper footing and balance at all times.
• Keep all parts of your body away from hot surfaces.
• Never put the machine down with the product activated unless you have it in clear sight.

WORKING TECHNIQUES

- The blower must not be used while on a ladder or scaffolding.

Line drawing of a worker using a power tool on a ladder, crossed by a diagonal line (no text or symbols)

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

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.

Throttle settings control

The speed of the air jet is regulated by means of the throttle. Select the speed best suited for respective tasks.

• Determine the desired airflow using the throttle.
- Press in the throttle position setting on the keypad.

- Depress the throttle fully to obtain the desired air speed.

The blower retains the latest throttle position setting in memory if the machine is shut down or when the battery is removed from the machine.

Temporary increase of airflow 'Boost'

A temporary increase in airflow, 'Boost', is used only on occasions when leaves and trash is stuck or when the normal airflow is not sufficient. In most cases, normal airflow is sufficient. An increase in airflow is used mainly for brief measures.

Press the Boost button on the keypad to temporarily raise the airflow. Maximum continuous Boost is 5 seconds.

Simple line drawing of a device with three circular icons and a central button (no text or symbols)

If raised airflow, Boost, is used continuously for longer than 5 seconds, the airflow will return to its original level. The activation indicator (LED lamp) for the Boost function will flash until the Boost function is available again.

MAINTENANCE

Inspection and maintenance

WARNING! Always remove the battery before any maintenance on the machine.

IMPORTANT! Never clean the battery or the battery charger with water. Strong cleaning agents can damage the plastic.

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. Only use original spare parts.

Check that the air intake is not blocked on all sides of the machine, 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.

Note 1: Noise emissions in the environment measured as sound power ( L_WA ) in conformity with EC directive 2000/14/EC. The difference between guaranteed and measured sound power is that the guaranteed sound power also includes dispersion in the measurement result and the variations between different machines of the same model according to Directive 2000/14/EC.

Note 2: Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion (standard deviation) of 3 dB (A).

Note 3: Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 2 m/s² .
