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 Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During the more than 300 years of beeing, 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 building and construction industry. Husqvarna ergonomics, usability, security and environmental protection. That is the reason why we have developed many different features to provide our products within these areas.

GENERAL SAFETY PRECA UTIONS

Stop switch

Use the stop switch to switch off the engine.

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

Vibration damping system

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

The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine

′s handle unit.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A mufﬂer ﬁtted with a catalytic converter is also designed to reduce harmful exhaust gases.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. We therefore ﬁt certain mufﬂers with a spark arrestor mesh. Check whether the mufﬂer on your machine is ﬁtted with this kind of mesh.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine.

Never use a machine that has a faulty mufﬂer.

Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.

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.

– English

Regularly check that the mufﬂer is securely attached to the machine.

If the mufﬂer on your machine is ﬁtted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.

WARNING! Mufﬂers ﬁtted with catalytic converters get 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!

GENERAL SAFETY PRECAUTIONS

WARNING! The inside of the mufﬂer contain chemicals that may be

carcinogenic. Avoid contact with these elements in the event of a damaged mufﬂer.

WARNING! Bear in mind that:

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!

Quick release (Balance Flex harness)

There is an easily accessible, quick release ﬁtted at the front as a safety precaution in case the engine catches ﬁre, or in any other situation that requires you to free yourself from the machine and harness.

Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.

Cutting equipment

• Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended ﬁle gauge.

sharpened chain increases the risk of accidents.

• Maintain the correct raker clearance! Follow our

instructions and use the recommended raker gauge.

Too large a clearance increases the risk of

kickback.

• Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.

• Keep cutting equipment well lubricated and

properly maintained!

more likely to break and lead to increased wear on the bar, chain and drive sprocket.

A damaged or badly

A poorly lubricated chain is

This section describes how you can achieve maximum clearing capacity and extend the life of the cutting attachment through correct maintenance and using the right type of cutting attachment.

• Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.

• Only use cutting equipment recommended by us!

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.

WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.

GENERAL SAFETY PRECAUTIONS

Speciﬁcation of bar and saw chain

When the cutting attachment supplied with your machine has to be replaced, because it is worn out or damaged, you must only ﬁt the types of bar and saw chain recommended by us.

Bar

• Length (inches/cm)

• Number of teeth on bar tip sprocket (T). Small number = small tip radius = low risk of kickback.

• Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.

• Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.

Chain

• Saw chain pitch (inches). (The distance between three drive links, divided by two.)

• Drive link width (mm/inches)

• Number of drive links.

Sharpening your chain and adjusting raker clearance

WARNING! The risk of kickback is increased with a badly sharpened chain!

• Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links.

• Lubrication hole and hole for the chain tensioner.

General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.

• A sharp chain eats its way through the wood and produces long, thick cuttings.

• The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip (B). The cutting depth is determined by the difference in height between the two.

• When you sharpen a cutting tooth there are ﬁve important factors to remember.

- Filing angle

- Cutting angle

- File position

- Round ﬁle diameter

- File depth

gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.

WARNING! The following faults will increase the risk of kickback considerably:

File angle too large

Cutting angle too small

File diameter too small

It is very difﬁcult to sharpen a chain correctly without the right equipment. We recommend that you use our ﬁle

Sharpening cutting teeth

To sharpen cutting teeth you will need a round ﬁle and a ﬁle gauge.

• Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difﬁcult to sharpen correctly.

• Always ﬁle cutting teeth from the inside face outwards. Reduce the pressure on the return stroke. File all the
