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 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 chainsaws 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 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 (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 operator
′ s manual
is passed on to the buyer.
Thank you for using a Husqvarna product.
Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and
appearance of products without prior notice.

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.) Tighten the nut using the socket spanner.
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.
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.
Cutting equipment
Saw blades are intended for cutting fibrous types of wood.
Grass blades and grass knifes are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.
General rules
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Keep the teeth of the blade correctly sharpened! Follow
our instructions and use the recommended file gauge. An
incorrectly sharpened or damaged blade increases the
risk of accidents.
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.
Keep the teeth of the blade correctly sharpened! Follow
our recommendations. Also refer to the instructions on
the blade packaging.
Maintain the correct blade setting! Follow our
instructions and use the recommended file gauge.
!
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
spark plug cap before you start to work
on it.
!
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.
H1158943-26,143RII,GB.fm Page 10 Monday, May 22, 2017 11:20 AM

GENERAL SAFETY PRECAUTIONS
English – 11
Keep the correct setting on the saw blade! Follow our
instructions and use the recommended setting tool. An
incorrectly set saw blade increases the risk of jamming
and blade thrust, and damage to the saw blade.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
Sharpening grass knifes and grass
blades
•See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and knifes
using a single-cut flat file.
• Sharpen all edges equally to maintain the balance of
the blade.
Sharpening the saw blade
•See the cutting attachment packaging for correct
sharpening instructions.
A correctly sharpened blade is essential for working
efficiently and to avoid unnecessary wear to the blade and
brush cutter.
• Make sure that the blade is well supported when you
file it. Use a 5.5 mm round file with a file holder.
• The filing angle is 15°. File alternate teeth to the right
and those in between to the left. If the blade has been
heavily pitted by stones it may be necessary to dress
the top edges of the teeth with a flat file, in exceptional
cases. If so, this should be done before filing with a
round file. The top edges must be filed down by the
same amount for all the teeth.
Adjust the blade setting. This should be 1 mm.
!
WARNING! Always discard a blade that is
bent, twisted, cracked, broken or
damaged in any other way. Never attempt
to straighten a twisted blade so that it
can be reused. Only use original blades
of the specified type.

Trimmer head
•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 before use. This will make
the cord tougher so that it lasts longer.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.

can result in injury to yourself or others.
Never use a harness with a defective
quick release.

FUEL HANDLING
18 – English
Fuel safety
Never start the machine:
1 If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 If you have spilled fuel on yourself or your clothes,
change your clothes.Wash any part of your body that
has come in contact with fuel. Use soap and water.
3 If the machine is leaking fuel. Check regularly for
leaks from the fuel cap and fuel lines.
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 open 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 petrol
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.
• The transport guard must always be fitted to the
cutting attachment when the machine is being
transported or in storage.
• Secure the machine during transport.
• In order to prevent unintentional starting of the engine,
the spark plug cap must always be removed during
long-term storage, if the machine is not under close
supervision and when performing all service
measures.
Fuel
CAUTION! The machine is equipped with a two-stroke
engine and must always be run using a mixture of petrol
and two-stroke 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.
Petrol
CAUTION! Always use a quality petrol/oil mixture at least
90 octane (RON). If your machine is equipped with a
catalytic converter (see chapter on Technical data) always
use a good quality unleaded petrol/oil mixture. Leaded
petrol will destroy the catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if
it is available.
• The lowest octane recommended is 90 (RON). If you
run the engine on a lower octane grade than 90 so-
called knocking can occur. This gives rise to a high
engine temperature, which can result in serious
engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
!
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
!
WARNING! Fuel and fuel fumes are
highly flammable and can cause serious
injury when inhaled or allowed to come
in contact with the skin. For this reason
observe caution when handling fuel and
make sure there is adequate ventilation.

Two-stroke oil
•For best results and performance use HUSQVARNA
two-stroke engine oil, which is specially formulated for
our air-cooled two-stroke engines.
• Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
• Never use oil intended for four-stroke engines.
• A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.
• Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.
1:33 (3%) with oils class JASO FB or ISO EGB
formulated for air-cooled, two-stroke engines.
Mixing
•Always mix the petrol and oil in a clean container
intended for fuel.
• Always start by filling half the amount of the petrol to
be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture. Add the remaining amount of
petrol.
• Mix (shake) the fuel mixture thoroughly before filling
the machine’s fuel tank.
• 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.
Fueling
•Always use a fuel container with an anti-spill valve.
• Clean the area around the fuel cap. Contamination in
the tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the
container before filling the tank.

WARNING! Taking the following
precautions, will lessen the risk of fire:
Do not smoke or place hot objects near
fuel.
Always shut off the engine before
refuelling.
Always stop the engine and let it cool for
a few minutes before refuelling.
When refuelling, open the fuel cap slowly
so that any excess pressure is released
gently.
Tighten the fuel cap carefully after
refuelling.
Always move the machine away from the
refuelling area and source before
starting.

STARTING AND STOPPING
20 – English
Check before starting
•Never use the machine without a guard nor with a
defective guard.
• All covers must be correctly fitted and undamaged
before you start the machine.
• Check the blade to ensure that no cracks have formed
at the bottom of the teeth or by the centre hole. The
most common reason why cracks are formed is that
sharp corners have been formed at the bottom of the
teeth while sharpening or that the blade has been
used with dull teeth. Discard a blade if cracks are
found.
• Check that the support flange is not cracked due to
fatigue or due to being tightened too much. Discard
the support flange if it is cracked.
• Ensure the locking nut has not lost its captive force.
The nut lock should have a locking force of at least 1.5
Nm.The tightening torque of the locking nut should be
35-50 Nm.
• Check that the blade guard is not damaged or
cracked. Replace the blade guard if it is exposed to
impact or is cracked.
• Check that the trimmer head and trimmer guard are
not damaged or cracked. Replace the trimmer head or
trimmer guard if they have been exposed to impact or
are cracked.
Starting and stopping
!
WARNING! The complete clutch cover
and shaft must be fitted before the
machine is started, otherwise the clutch
can come loose and cause personal
injury.
Always move the machine away from the
refuelling area and source before
starting. Place the machine on a flat
surface. Ensure the cutting attachment
cannot come into contact with any
object.
Make sure no unauthorised persons are
in the working area. Otherwise there is a
risk of serious personal injury.The safety
