INTRODUCTION
Dear customer!
Congratulations 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 Huskvarna 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 over 300 years of continuous operation, 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 chain saws 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. We develop, manufacture and market high quality motor driven products for forestry and gardening as
well as for building and construction industry.
Your purchase 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 (using, service, maintenance etc) the life span and
the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the
borrower or buyer gets the operator′s manual, so they will also know how to properly maintain and use it.
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.

GENERAL SAFETY PRECAUTIONS
GLOVES
Throttle lockout
Gloves should be worn when necessary, e.g., when fitting
cutting attachments.
The throttle lockout 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.
BOOTS
Wear boots with steel toe-caps and non-slip sole.
A
B
CLOTHING
Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
Wear clothes made of a strong fabric and avoid loose
clothing that can catch on twigs and branches. Always
wear heavy, long pants. Do not wear jewellery, shorts
sandals or go barefoot.Secure hair so it is above shoulder
level.
FIRST AID KIT
Always have a first aid kit nearby.
Press the throttle lockout and make sure it returns to its
original position when you release it.
Machine′s safety equipment
This section describes the machine′s safety equipment,
its purpose, and how checks and maintenance should be
carried out to ensure that it operates correctly. See the
”What is what?” section to locate where this equipment is
positioned on your machine.
Check that the throttle control and throttle lockout move
freely and that the return springs work properly.
IMPORTANT! All servicing and repair work on the
machine requires special training.This is especially true
of the machine′s safety equipment. If your machine fails
any of the checks described below you must contact
your service agent. When you buy any of our products

GENERAL SAFETY PRECAUTIONS
be checked. See instructions under the heading
Maintenance.
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to reduce vibration and make
operation easier.
Stop switch
Use the stop switch to switch off the engine.
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.
The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Cutting attachment guard
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.
Regularly check the vibration damping units for cracks or
deformation.
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
535RX, 535RXT
Check that the vibration damping element is undamaged
and securely attached.
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.
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.

a spark arrestor screen. Check whether the muffler on
your machine is fitted with this kind of screen.
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.
Quick release
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 brush
cutter.
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.
Certain harnesses also have a quick release fitted to the
support hook.
Regularly check that the muffler is securely attached to
the machine.
Check that the harness straps are correctly positioned.
Once the harness and machine have been adjusted,
check that the harness quick release works correctly.
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.
In countries that have a warm and dry climate there is a
significant risk of fire.We therefore fit certain mufflers with

muffler.
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! 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!
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.

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.
A locking nut is used to secure some types of cutting
attachment.
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.
!
Cutting equipment
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.
Saw blades are intended for cutting fibrous types of wood.
Grass blades and grass cutters are intended for cutting
coarse grass.
The nylon lining inside the locking nut must not be so worn

GENERAL SAFETY PRECAUTIONS
General rules
•
Sharpen all edges equally to maintain the balance of
the blade.
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
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.
!
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.
Sharpening the saw blade
•
See the cutting attachment packaging for correct
sharpening instructions.
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.
A correctly sharpened blade is essential for working
efficiently and to avoid unnecessary wear to the blade and
brush cutter.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
•
•
Make sure that the blade is well supported when you
file it. Use a 5.5 mm round file with a file holder.
Sharpening grass cutters and grass
blades
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
•
See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and cutters
using a single-cut flat file.

GENERAL SAFETY PRECAUTIONS
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.
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.

2
If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
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.
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.
Use low-emission gasoline, also known as alkylate
gasoline, if it is available.
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.
This engine is certified to operate on unleaded
gasoline.
•
•
When storing and transporting fuel always use
approved containers intended for this purpose.
•
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

Keep a good balance and a firm foothold. Do not
overreach. Keep proper footing and balance at all
times.
Basic safety rules
Always hold the machine with both hands. Hold the
machine on the right side of your body. Keep all parts
of your body away from the hot surfaces. Keep all
parts of your body away from the rotating cutting
attachment.

•
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.

Keep the cutting attachment below waist level.
Switch off the engine before moving to another area.
Fit the transport guard before carrying or transporting
the equipment any distance.
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.

WORKING TECHNIQUES
•
Start at whichever end of the area is easiest, and clear
an open space from which to work.
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.
!
•
Work systematically to and fro across the area,
clearing a width of around 4-5 m on each pass. This
exploits the full reach of the machine in both directions
and gives the operator a convenient and varied
working area to work in.
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.
!
•
•
Clear a strip around 75 m long. Move your fuel can as
work progresses.
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.
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.
•
You should plan the strip so that you avoid going over
ditches or other obstacles on the ground.You should
also orient the strip to take advantage of wind
conditions, so that cleared stems fall in the cleared
area of the stand.
WARNING! Sometimes branches or
grass get caught between the guard and
cutting attachment. Always stop the
engine before cleaning.
!
Working methods
WARNING! Machines fitted with saw
blades or grass blades can be thrown
violently to the side when the blade comes
into contact with a fixed object.This is
called blade thrust. A blade thrust can be
violent enough to cause the machine and/
or operator to be propelled in any
!
direction, and possibly lose control of the
machine. Blade thrust can occur without
warning if the machine snags, stalls or
binds. Blade thrust is more likely to occur
in areas where it is difficult to see the
material being cut.
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, blade thrust can
occur if you attempt to cut thick stems
with this area of the blade.
•
Before you start clearing, check the clearing area, the
type of terrain, the slope of the ground, whether there
are stones, hollows etc.

WORKING TECHNIQUES
•
To fell a tree forwards, the bottom of the tree should be
pulled backwards. Pull the blade backwards with a
quick, firm movement.
Forestry clearing using a saw blade
•
The risk of blade thrust increases with increasing
stem size.You should therefore avoid cutting with the
area of the blade between 12 o’clock and 3 o’clock.
•
Large stems must be cut from two sides. First
determine which direction the stem will fall. Make the
first cut on the felling side.Then finish cutting the stem
from the other side. Adjust the cutting pressure to
match the size of the stem and the hardness of the
wood.Small stems require more pressure, while large
stems require less pressure.
•
To fell to the left, the bottom of the tree should be
pushed to the right. Tilt the blade and bring it
diagonally down to the right, exerting firm pressure.At
the same time push the stem using the blade guard.
Cut with the area of the blade between 3 o’clock and
5 o’clock. Apply full throttle before advancing the
blade.
•
To fell to the right, the bottom of the tree should be
pushed to the left.Tilt the blade and bring it diagonally
up to the right. Cut with the area of the blade between
3 o’clock and 5 o’clock so that the direction of rotation
of the blade pushes the bottom of the tree to the left.
•
•
If the stems are tightly packed, adapt your walking
pace to suit.
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.
Brush cutting with a saw blade
•
Thin stems and brush are mown down. Work with a
sawing movement, swinging sideways.
•
•
Try to cut several stems in a single sawing movement.
With groups of hardwood stems, first clear around the
group. Start by cutting the stems high up around the
outside of the group to avoid jamming. Then cut the
stems to the required height. Now try to reach in with
the blade and cut from the centre of the group. If it is

machine on the ground before you start to collect the
cut material.
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.
Grass clearing using a grass blade
•
•
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.
•
•
•
Grass blades and grass cutters must not be used on
woody stems.
Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
A grass blade is used for all types of tall or coarse
grass.
Clearing
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.
•
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.
•
•
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.
•
•
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.
Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stroke and stand
firmly again.
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.
•
•
Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the ground.
Reduce the risk of material wrapping around the blade
by following these instructions:
1Always work at full throttle.
2Avoid the previously cut material during the return
stroke.

WORKING TECHNIQUES
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
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.
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.
Adjustment of the idle speed
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.
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.
T
•
•
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
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 = High speed jet
!
T = Idle adjustment screw
L
H
Adjusting the start throttle speed
The correct start throttle speed is set by means of an
adjuster on the rear of the handle next to the cable. Use
this screw (4 mm Allen screw) to increase or decrease the
start throttle speed.
T
•
•
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.

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.
Press the start throttle lock as described under the
heading Starting and stopping.

Cooling system
Muffler
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
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.
3
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.

3
Air intake on the starter.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
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.
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.
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.

MAINTENANCE
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
Spark plug
Loss of engine power
Unnecessary wear to engine parts
Excessive fuel consumption.
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.
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.
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder.
Oiling the air filter
Note: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.
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
