SAFETY INSTRUCTIONS
Cutting attachment guard
Muffler
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.
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.
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.
!
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
For mufflers it is very important that you follow the instructions
on checking, maintaining and servicing your machine. See
instructions under the heading Checking, maintaining and
servicing the machine’s safety equipment.
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!
!
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration.
The machine′s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine′s handle unit.
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:
!
WARNING! Overexposure to vibration can
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Engine exhaust fumes contain carbon
monoxide, which can cause carbon
monoxide poisoning. For this reason you
should not start or run the machine indoors,
or anywhere that is poorly ventilated.
!
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.
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!

Smaller machines generally require small trimmer heads
Starting
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.
WARNING! When the engine is started with
the choke in either the choke or start throttle
positions the cutting attachment will start to
rotate immediately.
!
•
•
Make sure that the cutter on the trimmer guard is intact.
This is used to cut the cord to the correct length.
•
The complete clutch cover and shaft must be fitted before
the machine is started, otherwise the clutch can come
loose and cause personal injury.
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.
•
•
Never start the machine indoors. Exhaust fumes can be
dangerous if inhaled.
IMPORTANT! Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the machine
will generate harmful vibration.

IMPORTANT!
Grass trimming using a trimmer head and
plastic blades
This section describes the basic safety precautions for
working with clearing saws and trimmers.
If you encounter a situation where you are uncertain how to
proceed you should ask an expert. Contact your dealer or
your service workshop.
Trimming
Avoid all usage which you consider to be beyond your
capability.
•
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.
You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.
Basic safety rules
1
•
Look around you:
•
•
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.
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.
Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
•
CAUTION! Do not use the machine unless you are able to
call for help in the event of an accident.
2
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.

SAFETY INSTRUCTIONS
Clearing
Sweeping
•
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.
•
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.
WARNING! Neither the operator of the
machine nor anyone else may attempt to
remove the cut material while the engine is
!
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.
running or the blade is rotating, as this can
result in serious injury. Stop the engine and
blade 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.
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.
WARNING! Watch out for thrown objects.
Always wear eye protection. Never lean over
the cutting attachment guard. Stones,
rubbish, etc. can be thrown up into the eyes
causing blindness or serious injury.
!
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be kept outside the safety zone of 15
m. Stop the machine immediately if anyone
approaches.
•
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.

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!
!
Adjusting the carburettor involves adapting the engine to
suit local conditions, e.g. climate, altitude and the petrol.
Basic setting
Cooling system
The basic carburettor settings are adjusted during testing at
the factory.
The carburettor should be adjusted to prevent damaging the
engine when the machine is always used at altitudes over
1500 metres above seal level.
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
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.
!
Muffler
The cooling system consists of:
1
2
3
4
Air intake on the starter.
Fins on the flywheel.
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.
Cooling fins on the cylinder.
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.
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.
Spark plug
The spark plug condition is influenced by:
•
•
Incorrect carburettor adjustment.
A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.

MAINTENANCE
If the machine is low on power, difficult to start or runs poorly
Cleaning the air filter
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.
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.
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.
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.
Two-piece shaft
Oiling the air filter
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.
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.
Air filter
The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:
•
•
•
•
•
Carburettor malfunctions
Starting problems
Bevel gear
Loss of engine power
Unnecessary wear to engine parts.
Excessive fuel consumption.
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.
Clean the filter every 25 hours, or more regularly if conditions
are exceptionally dusty.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
