s safety equipment
s
ARNING! 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.
Check that the throttle control and throttle lockout move freely
and that the return springs work properly.
See instructions under the heading Start. Start the machine
and apply full throttle. Release the throttle and check that the
cutting attachment stops and remains at a standstill. If the
cutting attachment rotates with the throttle in the idle position
then the carburettor idle setting must be checked. See
instructions under the heading Maintenance.
Stop s witch
Use the stop s witch to switch off the engine.
Thr ottle lockout
The throttle loc kout is designed to prevent accidental
operation of the throttle control. When you press the lock (A)
(i.e. when you grasp the handle) it releases the throttle control
(B). When you release the handle the throttle control and the
throttle lockout both move back to their original positions. This
movement is controlled by two independent return springs.
This arrangement means that the throttle control is
automatically locked at the idle setting.
Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
Press the throttle lockout and make sure it returns to its
original position when you release it.
Start the engine and make sure the engine stops when you
move the stop switch to the stop setting.
Cutting attac hment guard
This guard is intended to pre vent 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.
ARNING! Never use a cutting attachment

Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to reduce vibration and make operation
easier.
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′s handle unit.
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.
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.
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!
WARNING! The inside of the muffler contain
chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a
damaged muffler.
–
English
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!
GENERAL SAFETY PRECAUTIONS
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.
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
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.
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.

FUEL HANDLING
Fuel handling
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 naked 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 gas station to find out
where to dispose of excess fuel.
• The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.
• Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and
!
inhaling fumes.
Fuel
Gasoline
Always use an unleaded quality petrol of at least 90 octane
(RON).
Use low-emission gasoline, also known as alkylate gasoline,
if it is available.
• The lowest recommended octane grade is 87
((RON+MON)/2). If you run the engine on a lower octane
grade than 87 so-called knocking can occur. This gives
rise to a high engine temperature and increased bearing
load, which can result in serious engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Engine oil
Check the oil level before starting the machine. A too low oil
level can cause serious damage to the engine.
When the machine is new the engine oil should be changed
after the first month or after 10 hours of operation.
• For the best result and function use HUSQVARNA engin
oil.
• When HUSQVARNA engine oil is not available another
high grade engine oil can be used. Contact your dealer
when selecting oil. Engine oil for four-stroke petrol
engines must be used. Quality class at least API SG. In
general viscosity class SAE 10W-40 is recommended.
• Never use oil intended for two-stroke engines.
Oil level
The machine must be switched off and placed on a flat
surface when you check the oil level.
Unscrew the oil cap, clean the dipstick located on the cap and
insert the cap again without screwing it down. Check the oil
level on the dipstick.
CAUTION! The machine is equipped with a four-stroke
engine. Make sure that there is always sufficient oil in the oil
tank.
WARNING! Fuel and fuel fumes are highly
inflammable 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.
WARNING! The catalytic converter muffler
gets very hot during and after use. This also
!
applies during idling. Be aware of the fire
hazard, especially when working near
flammable substances and/or vapours.
12 – English
When the oil level is low, top up using engine oil to the edge
of the oil refill hole.
Only use recommended engine oil.
FUEL HANDLING
Fueling
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 before starting.
Clean around the fuel cap. Clean the fuel and oil tank
regularly. The fuel filter should be changed at least once a
year. Contamination in the tanks causes malfunction.
Always move the machine about 3 metres from the refuelling
position before starting.
English – 13
STARTING AND STOPPING
Check before starting
• 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 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

WORKING TECHNIQUES
General working instructions
IMPORTANT!
This section takes up the basic safety precautions for
working with a trimmer.
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.
You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.
Basic safety rules
1 Look around you:
• To ensure that people, animals or other things cannot
affect your control of the machine.
• To ensure that people, animals, etc., do not come into
contact with the cutting attachment or loose objects that
are thrown out by the cutting attachment.
• CAUTION! Do not use the machine unless you are able to
call for help in the event of an accident.
2 Inspect the working area. Remove all loose objects, such
as stones, broken glass, nails, steel wire, string, etc. that
could be thrown out or become wrapped around the
cutting attachment.
3 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 often brings added risks, such as
icy ground, unpredictable felling direction, etc.
4 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.
6 Always hold the machine with both hands. Hold the
machine on the right side of your body.
7 Keep the cutting attachment below waist level.
8 The engine must be switched off before moving.
9 Never put the machine down with the engine running
unless you have it in clear sight.
WARNING! Neither the operator of the
machine nor anyone else may attempt to
!
remove the cut material while the engine is
running or the cutting equipment is rotating,
as this can result in serious injury.
Stop the engine and cutting equipment
before you remove material that has wound
around the blade shaft as otherwise there is
a risk of injury. The bevel gear can get hot
during use and may remain so for a while
afterwards. You could get burnt if you touch
it.
WARNING! Watch out for thrown objects.
Always wear approved eye protection. Never
!
lean over the cutting attachment guard.
Stones, rubbish, etc. can be thrown up into
the eyes causing blindness or serious injury.

Basic working techniques
Always slow the engine to idle speed after each working
operation. Long periods at full throttle without any load on the
engine can lead to serious engine damage.
WARNING! Sometimes branches or grass
get caught between the guard and cutting
!
attachment. Always stop the engine before
cleaning.
WORKING TECHNIQUES
Grass trimming with a trimmer head
Trimming
• Hold the trimmer head just above the ground at an angle.
It is the end of the cord that does the work. Let the cord
work at its own pace. Never press the cord into the area
to be cut.
• The cord can easily remove grass and weeds up against
walls, fences, trees and borders, however it can also
damage sensitive bark on trees and bushes, and damage
fence posts.
• Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
Clearing
• The clearing technique removes all unwanted vegetation.
Keep the trimmer head just above the ground and tilt it. Let
the end of the cord strike the ground around trees, posts,
statues and the like. CAUTION! This technique increases
the wear on the cord.
Sweeping
• The fan effect of the rotating cord can be used for quick
and easy clearing up. Hold the cord parallel to and above
the area to be swept and move the tool to and fro.
• When cutting and sweeping you should use full throttle to
obtain the best results.
• The cord wears quicker and must be fed forward more
often when working against stones, brick, concrete, metal
fences, etc., than when coming into contact with trees and
wooden fences.
• When trimming and clearing you should use less than full
throttle so that the cord lasts longer and to reduce the
wear on the trimmer head.
Cutting
• The trimmer is ideal for cutting grass that is difficult to
reach using a normal lawn mower. Keep the cord parallel
to the ground when cutting. Avoid pressing the trimmer
head against the ground as this can ruin the lawn and
damage the tool.
• Do not allow the trimmer head to constantly come into
contact with the ground during normal cutting. Constant
contact of this type can cause damage and wear to the
trimmer head.

MAINTENANCE
Carburetor
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.
Function
• The carburetor governs the engine’s speed via the throttle
control. Air and fuel are mixed in the carburetor.
• Setting the carburettor involves adapting the engine to suit
local conditions, e.g. climate, altitude and the petrol.
Basic setting
The basic carburetor settings are adjusted during testing at
the factory.
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
Adjusting the idle speed (T)
Muffler
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether your
machine is fitted with a catalytic converter.
The muffler is designed to reduce the noise level and to direct
the exhaust gases away from the operator. The exhaust
gases are hot and can contain sparks, which may cause fire
if directed against dry and combustible material.
The muffler on your machine is equipped with a spark arrestor
screen, this should be cleaned regularly. A blocked screen will
cause the engine to overheat and may lead to serious
damage.
Check that the air filter is clean. When the idle speed is
correct, the cutting attachment should not rotate. If
adjustment is required, close (turn clockwise) the idle
adjustment screw T, with the engine running, until the cutting
attachment starts to rotate. Open (turn anticlockwise) the
screw until the cutting attachment stops. The idle speed is
correctly set when the engine runs smoothly in all positions,
and there is a clear margin to the speed at which the cutting
attachment starts to rotate.
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
!
stops, contact your dealer/service
workshop. Do not use the machine until it
has been correctly adjusted or repaired.
CAUTION! Never use a machine with a defective muffler.
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!
18 – English
MAINTENANCE
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Fins on the flywheel.
3 Cooling fins on the cylinder.
4 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Spark plug
Two-piece shaft
The drive shaft end in the lower shaft should be lubricated
with grease every 30 hours. There is a risk that the drive shaft
ends (splined coupling) on models with two-piece shafts will
seize if they are not lubricated regularly.
Air filter
The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if conditions
are exceptionally dusty.
The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
If the machine is low on power, difficult to start or runs poorly
at idle speed: always check the spark plug first before taking
any further action. If the spark plug is dirty, clean it and check
that the electrode gap is 0,6-0,7 mm. The spark plug should
be replaced after about a month in operation or earlier if
necessary.
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.
Check that the spark plug is fitted with a suppressor.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry before
refitting it.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced with
a new one at regular intervals. A damaged air filter must
always be replaced.
If the machine is used in dusty conditions the air filter should
be soaked in oil. See instructions under the heading Oiling the
air filter.
English – 19
MAINTENANCE
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The
filter oil contains a solvent to make it spread evenly through
the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.
Bevel gear
The bevel gear is filled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is filled three-quarters full with grease. Use
HUSQVARNA special grease.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
IMPORTANT! Use only HUSQVARNA replacement parts.
Use of other brands of replacement parts can cause
damage to your unit or injury to the operator or others. Your
warranty does not cover damage or liability caused by the
use of accessories and/or attachments not specifically
recommended by HUSQVARNA.
