SAFETY INSTRUCTIONS  
Cutting attachment guard  
Quick release  
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.  
There is an easily accessible, quick release fitted at the front  
as a safety precaution in case the engine catches fire, or in  
any other situation that requires you to free yourself from the  
machine and harness. See instructions under the heading  
Adjusting the harness and clearing saw.  
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.  
!
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.  
Vibration damping system  
Your machine is equipped with a vibration damping system  
that is designed to minimize vibration and make operation  
easier.  
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.  
Using incorrectly wound cord or a blunt or incorrect cutting  
attachment (wrong type or incorrectly filed, see instructions  
under the heading Filing the blade) increases the level of  
vibration.  
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.  
The machine′s vibration damping system reduces the transfer  
of vibration between the engine unit/cutting equipment and  
the machine′s handle unit.  
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! Overexposure to vibration can  
lead to circulatory damage or nerve damage  
in people who have impaired circulation.  
!
WARNING! The inside of the muffler contain  
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.  
chemicals that may be carcinogenic. Avoid  
contact with these elements in the event of a  
damaged muffler.

SAFETY INSTRUCTIONS  
•
Make sure that the blade is well supported when you file  
•
Smaller machines generally require small trimmer heads  
it. Use a 5.5 mm round file with a file holder.  
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.  
•
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.  
IMPORTANT! Always ensure the trimmer cord is wound  
tightly and evenly around the drum, otherwise the machine  
will generate harmful vibration.  
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.

sharpening instructions.  
•
•
Sharpen blades and cutters using a single-cut flat file.  
Sharpen all edges equally to maintain the balance of the  
blade.  
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

distributes the load across both shoulders.  
This section describes the basic safety precautions for  
working with clearing saws and trimmers.  
Safety release  
If you encounter a situation where you are uncertain how to  
proceed you should ask an expert. Contact your dealer or  
your service workshop.  
At the front is an easily accessible, quick release. Use this if  
the engine catches fire or in any other emergency situation  
that requires you to free yourself from the machine and  
harness.  
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  
Spreading the load on your shoulders  
A well-adjusted harness and machine makes work much  
easier. Adjust the harness for the best working position.  
Tension the side straps so that the weight is evenly distributed  
across both shoulders.  
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
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.  
Correct height  
Adjust the shoulder strap so that the cutting attachment is  
parallel to the ground.  
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.

SAFETY INSTRUCTIONS  
Correct balance  
WARNING! Avoid cutting with the area of the  
blade between the 12 o’clock and 3 o’clock  
positions. Because of the speed of rotation  
of the blade kickback can occur if you  
attempt to cut thick stems with this area of  
the blade.  
Let the cutting attachment rest lightly on the ground. If you  
use a saw blade it should balance about 10 cm above the  
ground to prevent contact with stones and the like. Adjust the  
position of the support hook to balance the clearing saw  
correctly.  
!
Working methods  
•
•
•
Before you start clearing, check the clearing area, the  
type of terrain, the slope of the ground, whether there are  
stones, hollows etc.  
On sloping ground you should work along the slope. It is  
much easier to work along a slope than it is to work up and  
down it.  
The strip should be planned so that you avoid going over  
ditches or other obstacles on the ground.  
Basic working techniques  
Brush cutting with a saw blade  
•
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.  
•
Cut through thin stems and brush. Work with a sawing  
movement, swinging sideways.  
Terms  
•
•
•
Use a saw blade for cutting woody growth with thin stems.  
Use a grass cutter or grass blade for clearing grass.  
•
Avoid cutting with the area of the blade between the 12  
o’clock and 3 o’clock positions.  
Use a trimmer head or plastic blades for lighter clearing  
work, for example along verges or around trees.  
WARNING! Sometimes branches or grass  
get caught between the guard and cutting  
attachment. Always stop the engine before  
cleaning.  
!
WARNING! If the blade jams in a stem, never  
jerk the machine free. If you do this the  
blade, bevel gear, shaft or handlebar may be  
damaged. Release the handles, grip the  
shaft with both hands and gently pull the  
machine free.  
!
The ABC of clearing  
Always use the correct equipment.  
Make sure the equipment is well adjusted.  
Follow the safety precautions.  
Organise your work carefully.  
Always use full throttle when starting to cut with the blade.  
Always use sharp blades.  
Avoid stones.

SAFETY INSTRUCTIONS  
Grass clearing using a grass blade  
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.  
!
•
Grass blades and grass cutters must not be used on  
woody stems.  
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  
•
•
A grass blade is used for all types of tall or coarse grass.  
The grass is cut down with a sideways, swinging  
movement, where the movement from right-to-left is the  
clearing stroke and the movement from left-to-right is the  
return stroke. Let the left-hand side of the blade (between  
8 and 12 o’clock) do the cutting.  
around without first checking behind you to  
make sure no-one is within the safety zone.  
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.  
•
•
If the blade is angled to the left when clearing grass, the  
grass will collect in a line, which makes it easier to collect,  
e.g. by raking.  
Try to work rhythmically. Stand firmly with your feet apart.  
Move forward after the return stroke and stand firmly  
again.  
•
•
Let the support cup rest lightly against the ground. It is  
used to protect the blade from hitting the ground.  
•
•
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 material wrapping around the blade by  
following these instructions:  
1
2
Always work at full throttle.  
Reduce the risk of damaging plants by shortening the  
cord to 10-12 cm and reducing the engine speed.  
Avoid the previously cut material during the return  
stroke.  
Clearing  
•
Stop the engine, unclip the harness and place the  
machine on the ground before you start to collect the cut  
material.  
•
The clearing technique removes all unwanted vegetation.  
WARNING! Neither the operator of the  
machine nor anyone else may attempt to  
remove the cut material while the engine is  
running or the blade is rotating, as this can  
result in serious injury.  
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.  
!
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.  
•
•
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

SAFETY INSTRUCTIONS  
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.  
WARNING! Neither the operator of the  
machine nor anyone else may attempt to  
remove the cut material while the engine is  
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.  
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.

use a saw blade it should balance about 10 cm above the  
ground to prevent contact with stones and the like. Adjust the  
position of the support hook to balance the clearing saw  
correctly.  
WARNING! When using a clearing saw it  
must always be hooked securely to the  
harness. Otherwise you will be unable to  
control the clearing saw safely and this can  
result in injury to yourself or others. Never  
use a harness with a defective quick release.  
!
Standard harness  
Quick release  
At the front is an easily accessible, quick release. Use this if  
the engine catches fire or in any other emergency situation  
that requires you to free yourself from the machine and  
harness.

FUEL HANDLING  
When the oil level is low, top up using engine oil to the edge  
of the oil refill hole.  
Fuel  
CAUTION! The machine is equipped with a four-stroke  
engine. Make sure that there is always sufficient oil in the oil  
tank.  
WARNING! Always ensure there is adequate  
ventilation when handling fuel.  
!
Only use recommended engine oil.  
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.  
Fuelling  
WARNING!Taking the following precautions,  
will lessen the risk of fire:  
Gasoline  
!
•
•
Use high-grade unleaded petrol of at least 86 octane.  
If the machine is not used for some time the fuel tank  
should be emptied and cleaned.  
Do not smoke or place hot objects near fuel.  
Always shut off the engine before refuelling.  
When refuelling, open the fuel cap slowly so  
that any excess pressure is released gently.  
Engine oil  
Check the oil level before starting the machine. A too low oil  
level can cause serious damage to the engine.  
Tighten the fuel cap carefully after refuelling.  
Always move the machine away from the  
refuelling area before starting.  
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.  
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.  
•
When HUSQVARNA engine oil is not available another  
high grade engine oil can be used. Contact your dealer  
when selecting oil. Mineral oil or semisynthetic oil should  
be used. In general SAE 10W-40 is recommended.  
Always move the machine about 3 metres from the refuelling  
position before starting.  
•
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.

STARTING AND STOPPING  
Check before starting  
Starting and stopping  
•
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.  
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 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 distance  
is 15 metres.  
•
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.  
Cold engine  
Ignition: Set the stop switch to the start position.  
•
•
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.  
Choke: Set the choke control in the choke position.  
Check that the blade guard is not damaged or cracked.  
Replace the blade guard if it is exposed to impact or is  
cracked.  
Primer bulb: Press the primer bulb repeatedly until fuel  
begins to fill the bulb. The bulb need not be completely filled.  
•
Check that the trimmer head and trimmer guard are not  
damaged or cracked. Replace the trimmer head or

STARTING AND STOPPING  
Warm engine  
Starting  
Ignition: Set the stop switch to the start position.  
Choke: Put the choke in working position.  
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.  
!
Hold the body of the machine on the ground using your left  
hand (CAUTION! Not with your foot!). Grip the starter handle,  
slowly pull out the cord with your right hand until you feel  
some resistance (the starter pawls grip), now quickly and  
powerfully pull the cord.Never wrap the starter cord around  
your hand  
Primer bulb: Press the primer bulb repeatedly until fuel  
begins to fill the bulb. The bulb need not be completely filled.  
Repeat pulling the cord until the engine starts. When the  
engine starts. return choke control to run position and apply  
full throttle; the throttle will automatically disengage from the  
start setting.  
CAUTION! Do not pull the starter cord all the way out and do  
not let go of the starter handle when the cord is fully extended.  
This can damage the machine.  
For throttle handles with a start throttle  
lock:  
Set the throttle to the start position by first pressing the throttle  
lock and the throttle trigger, then pressing the start throttle  
button (A). Then release the throttle lock and the throttle  
trigger, followed by the start throttle button. The throttle  
function is now activated. To return the engine to idle, press  
the throttle lock and throttle trigger again.  
Stopping  
Stop the engine by switching off the ignition.  
PART THROTTLE FUNCTION  
It is possible to set the engine for part throttle operation using  
the dial on the side of the throttle handle. Turn the dial up to  
decrease the part throttle rpm.Turn the dial down to increase  
the part throttle rpm.When you have set the part throttle rpm  
you will feel increased resistance when you press the throttle  
trigger.This increased resistance makes it easier to maintain  
a constant part throttle setting.To obtain full throttle, press the  
throttle trigger a little harder so that it goes past the part  
throttle setting. As soon as you release the throttle trigger the  
engine will return to idle. The part throttle function does not  
lock the engine at a given rpm, it is simply a brake that makes  
it easier to maintain the engine at a given rpm.

MAINTENANCE  
The muffler on your machine is equipped with a spark arrestor  
Carburettor  
mesh, this should be cleaned regularly. A blocked mesh will  
cause the engine to overheat and may lead to serious  
damage.  
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  
CAUTION! Never use a machine with a defective muffler.  
•
•
The carburettor governs the engine’s speed via the  
throttle control. Air and fuel are mixed in the carburettor.  
The air/fuel mixture is adjustable. Correct adjustment is  
essential to get the best performance from the machine.  
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!  
!
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  
Oiling 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.  
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.  
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.  
Air filter  
The air filter must be regularly cleaned to remove dust and dirt  
in order to avoid:  
Bevel gear  
•
•
•
•
•
Carburettor malfunctions  
Starting problems  
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.  
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 grease in the bevel gear does not normally need to be  
changed except if repairs are carried out.  
Cleaning the air filter  
CAUTION! 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.  
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.  
Sharpening grass cutters and grass  
blades  
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.  
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.

Sharpening the saw blade  
WARNING! Using an incorrect cutting  
attachment or an incorrectly sharpened  
blade increases the risk of kickback.  
!
•
•
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  
clearing saw.  
•
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.
