							FUEL HANDLING
12 – English1151471-95   Rev. 1  2009-01-16
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 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.
• 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.
• 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 been run using a mixture of gasoline 
and two-stroke engine 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.
Gasoline
CAUTION!  Always use a quality gasoline/oil mixture with an 
octane rating of at least 87 octane ((RON+MON)/2). If your 
machine is equipped with a catalytic converter (see chapter 
on Technical data) always use a good quality unleaded 
gasoline/oil mixture. Leaded gasoline will destroy the catalytic 
converter.
Use low-emission gasoline, also known as alkylate gasoline, 
if it is available. 
This engine is certified to operate on unleaded gasoline.
•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.
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.
• Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.
!
WARNING! Take care when handling fuel. 
Bear in mind the risk of fire, explosion and 
inhaling fumes.
!
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.

Mixing
•Always mix the gasoline and oil in a clean container 
intended for fuel.
• Always start by filling half the amount of the gasoline to be 
used. Then add the entire amount of oil. Mix (shake) the 
fuel mixture. Add the remaining amount of gasoline.
• 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
•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! 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.
!
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. 
						

							STARTING AND STOPPING
14 – English1151471-95   Rev. 1  2009-01-16
Check before starting
•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.
• 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.
Starting and stopping

General working instructions
Basic safety rules
1Look 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.
5 Keep a good balance and a firm foothold.
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.
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.
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.
!
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.
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. Never swing the machine 
around without first checking behind you to 
make sure no-one is within the safety zone.
!
WARNING! Sometimes branches or grass 
get caught between the guard and cutting 
attachment. Always stop the engine before 
cleaning.

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.
• 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.
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.  
						

							MAINTENANCE
18 – English1151471-95   Rev. 1  2009-01-16
Carburetor
Your Husqvarna product has been designed and 
manufactured to specifications that reduce harmful 
emissions. After the engine has used 8-10 tanks of fuel the 
engine will be run-in. To ensure that it continues to run at peak 
performance and to minimise harmful exhaust emissions 
after the running-in period, ask your dealer/service workshop 
(who will have a rev counter at their disposal) to adjust your 
carburettor.
Function
•The carburetor governs the engine’s speed via the throttle 
control. Air and fuel are mixed in the carburetor. The air/
fuel mixture is adjustable. Correct adjustment is essential 
to get the best performance from the machine.
• The setting of the carburetor means that the engine is 
adapted to local conditions, for example, the climate, 
altitude, fuel and the type of 2-stroke oil.
• The carburetor has three adjustment controls:
L = Low speed jet
H = High speed jet
T = Idle adjustment screw
• The L and H-jets are used to adjust the supply of fuel to 
match the rate that air is admitted, which is controlled with 
the throttle. If they are screwed clockwise the air/fuel ratio 
becomes leaner (less fuel) and if they are turned anti-
clockwise the ratio becomes richer (more fuel). A lean 
mixture gives a higher engine speed and a rich mixture 
gives a lower engine speed.
• The T-screw regulates the throttle setting at idle speed. If 
the T-screw is turned clockwise this gives a higher idle 
speed; turning it anti-clockwise gives a lower idle speed.
Basic setting
•The basic carburetor settings are adjusted during testing 
at the factory. The basic setting is richer than the optimal 
setting and should be maintained for the first few hours the 
machine is in use. The carburettor should then be finely 
adjusted. Fine adjustment should be carried out by a 
skilled technician.
CAUTION!  If the cutting attachment rotates when the engine 
is idling the idle adjustment screw T should be turned anti-
clockwise until the cutting attachment stops.
Rec. idle speed 2700 rpm
Recommended max. speed: See the Technical data section.
Fine adjustment
•When the machine has been ”run-in” the carburetor 
should be finely adjusted. 
The fine adjustment should 
be carried out by a qualified person.
 First adjust the L-
jet, then the idling screw T and then the H-jet.
Conditions
•Before any adjustments are made, make sure that the air 
filter is clean and the air filter cover is fitted. If you adjust 
the carburettor when the air filter is dirty it will result in a 
leaner mixture when the filter is finally cleaned. This can 
lead to serious engine damage.
• Carefully turn both jets, L and H, so that they are midway 
between fully screwed in and fully screwed out.
• Do not attempt to adjust the L and H jets beyond either 
stop as this could cause damage.
• Now start the machine according to the starting 
instructions and let it warm up for 10 minutes.
CAUTION!  If the cutting attachment rotates when the engine 
is idling the idle adjustment screw T should be turned anti-
clockwise until the cutting attachment stops.
Low speed jet L
Try to find the highest idling speed, turning the low speed 
needle L clockwise respectively counter-clockwise. When the 
highest speed has been found, turn the low speed needle L 1/
4 turn counter-clockwise.
CAUTION!  If the cutting attachment rotates when the engine 
is idling the idle adjustment screw T should be turned anti-
clockwise until the cutting attachment stops.
!
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.
!
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.

Fine adjustment of the idle speed T
Adjust the idle speed using the idle adjustment screw T, if it is 
necessary to readjust. First turn the idle adjustment screw T 
clockwise until the cutting attachment starts to rotate. Then 
turn the screw anticlockwise until the cutting attachment 
stops. The idle speed is correctly adjusted when the engine 
will run smoothly in every position. The idle speed should also 
be well below the speed at which the cutting attachment starts 
to rotate.
High speed jet H
The high speed jet H affects the engine power, speed, 
temperature and fuel consumption. If the high speed jet H is 
set too lean (screwed in too far) the engine speed will be too 
high and cause engine damage. Do not let the engine run at 
full speed for more than 10 seconds.
Apply full throttle and turn the high speed jet H very slowly 
clockwise until the engine slows down. Then turn the high 
speed jet H very slowly anticlockwise until the engine starts to 
run unevenly. Now turn the high speed jet H slowly clockwise 
a little way until the engine runs smoothly. 
Note that the engine should not be under load when you 
adjust the high speed jet H. You should therefore remove the 
cutting attachment, nut, support flange and drive disc before 
adjusting the high speed jet H.
The high speed jet H is adjusted correctly when the machine 
burbles a little. If the machine races then the setting is too 
lean. If the engine produces a lot of smoke and burbles a lot 
then the setting is too rich.
CAUTION!  For optimum adjustment of the carburettor, 
contact a qualified dealer/service workshop that has a 
revolution counter at their disposal. 
Correctly adjusted carburetor
When the carburetor is correctly adjusted the machine will 
accelerate without hesitation and burble a little at maximum 
speed. It is also important that the cutting attachment does 
not rotate at idle. If the low speed jet L is set too lean it may 
cause starting difficulties and poor acceleration.
If the high speed jet H is set too lean it will result in less power, 
less performance, poor acceleration and/or damage to the 
engine.
If both the L and H jets are set too rich it will results in 
acceleration problems or too low a working speed.
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.
Some mufflers are equipped with a special spark arrestor 
screen. If your machine has this type of muffler, you should 
clean the screen at least once a week. This is best done with 
a wire brush. On mufflers without a catalytic converter the 
screen should be cleaned weekly, or replaced if necessary. 
On mufflers fitted with a catalytic converter the screen should 
be checked, and if necessary cleaned, monthly. 
If the screen 
is damaged it should be replaced.
 If the screen is 
frequently blocked, this can be a sign that the performance of 
the catalytic converter is impaired. Contact your dealer to 
inspect the muffler. A blocked screen will cause the machine 
to overheat and result in damage to the cylinder and piston.
CAUTION!  Never use a machine with a defective muffler.
!
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.
H!
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!

20 – English1151471-95   Rev. 1  2009-01-16
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
The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type of 
oil).
• 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 0.020 inch (0.5 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.
Two-piece shaft 
(326LDx)
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.
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.
