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 waterpowered 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

s manual as a valuable document. By following its ′ 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

be checked. See instructions under the heading Maintenance.

Vibration damping system

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

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.

Cutting attachment guard

This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment.

Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked.

Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.

WARNING! Never use a cutting attachment without an approved guard.

See the chapter on Technical data. If an incorrect or faulty guard is ﬁtted this can cause serious personal injury.

Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment.

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

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.

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.

– English

1151387-49 Re v .2 2009-06-10

GENERAL SAFETY PRECAUTIONS

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 screen. Check whether the mufﬂer on your machine is ﬁtted with this kind of screen.

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 that the mufﬂer is securely attached to the machine.

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!

Locking nut

A locking nut is used to secure some types of cutting attachment.

When ﬁtting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.)

When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut.

If the mufﬂer on your machine is ﬁtted with a spark arrestor screen this must be cleaned regularly. A blocked screen 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!

1151387-49 Rev.2 2009-06-10

The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.

GENERAL SAFETY PRECAUTIONS

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to:

• Reduce the risk of blade thrust.

• Obtain maximum cutting performance.

• Extend the life of cutting equipment.

IMPORTANT! Only use cutting attachments with the guards we

recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to

check the correct way to load the cord and the correct cord diameter.

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.

WARNING! A faulty cutting attachment may increase the risk of accidents.

Trimmer head

IMPORTANT! Always ensure the trimmer cord is wound tightly and

evenly around the drum, otherwise the machine will generate harmful vibration.

• Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.

• Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared.

• The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

• Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.

Fitting the loop handle

ASSEMBLY

Fitting a trimmer guard and Superauto II 1" trimmer head

• Clip the loop handle onto the shaft. Note that the loop handle must be ﬁtted between the arrows on the shaft.

• Slide the spacer into the slot in the loop handle.

• Fit the nut, washer and screw. Do not overtighten.

• Now adjust the trimmer to give a comfortable working position. Tighten the screw.

Assembling the cutting equipment

WARNING!

When ﬁtting the cutting attachment it is extremely important that the raised section on the drive disc/support ﬂange engages correctly in the centre hole of the cutting attachment. If the cutting attachment is ﬁtted incorrectly it can result in serious and/or fatal personal injury.

• Fit the correct trimmer guard (A) for use with the trimmer head. Hook the guard onto the ﬁtting on the shaft and secure it with the bolt (L).

• Fit the drive disc (B) on the output shaft.

• Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing.

• Insert the locking pin (C) in the hole to lock the shaft.

• To ﬁt the trimmer head, ﬁrst separate the two halves (see diagram). Proceed as follows:

• Insert a ﬁnger into the centre hole of the cover (I) while grasping the cover with your other ﬁngers. Using the index ﬁnger and thumb of your other hand, release the two catches (J) that engage in the cut-outs in the bottom half (K). Pull apart the trimmer head, grasping the cover ﬁrmly.

• Place the cover (I) and the support ﬂange (F) on the output shaft. Ensure that the drive disc’s guide locates correctly in the cover’s centre hole.

• Fit the nut (G). The nut must be tightened to a torque of 35-50 Nm (3.5-5 kpm). Use the socket spanner in the tool kit. Hold the shaft of the spanner as close to the blade guard as possible. To tighten the nut, turn the spanner in the opposite direction to the direction of rotation (Caution! left-hand thread).

WARNING! Never use a cutting attachment without an approved guard.

See the chapter on Technical data. If an incorrect or faulty guard is ﬁtted this can cause serious personal injury.
