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

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

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).
