SAFETY INSTRUCTIONS
Personal protective equipment
The machineʼs safety equipment
This section describes the machineʼs safety equipment, its func-
tion and how checks and maintenance are carried out to ensure
that it operates correctly. (See the chapter “What is what” to
locate where this equipment is positioned on your machine.)
IMPORTANT INFORMATION
• An edger used incorrectly or carelessly can become a
dangerous tool, that can cause serious or fatal injury
to the operator or others. It is extremely important that
you read and understand the content of this manual.
WARNING!
Never use a machine with defective safety
equipment. Follow the control, maintenance
and service instructions described in this
section.
• When using an edger, personal protective equipment
approved by the appropriate authorities must be used.
Personal protective equipment does not eliminate the
risk of accidents, however, it can reduce the effects of
an injury in the event of an accident. Ask your dealer
for help when choosing protective equipment.
!
WARNING!
Remove your hearing protection as soon as
you stop the engine, so that you can hear any
noises or warning signals.
1. Throttle trigger
lock
!
GLOVES
Gloves should be worn when
necessary, e.g., when assem-
bling cutting equipment.
The throttle trigger lock is
designed to prevent the throttle
from accidentally being en-
gaged. When the trigger lock
(A) is pressed into the handle
(= when you hold the handle)
the throttle (B) is released.
When the grip on the handle
is released the throttle and
the throttle trigger lock return
to their original positions. This
takes place via two independ-
ent return spring systems.
This means that the throttle
is automatically locked in the
“idling” position.
EAR PROTECTION
Ear protection offering suffi-
cient dampening effect should
be used.
EYE PROTECTION
Blows from branches or
objects thrown by the rotating
cutting equipment can damage
the eyes.
2. Stop switch
The stop switch should be
used to stop the engine.
BOOTS
Use anti-slip and stable boots.
"
CLOTHING
Wear clothes made of a strong
fabric and avoid loose clothing
that can catch on shrubs and
branches. Always wear heavy-
duty long pants. Do not wear
jewellery, shorts, sandals or go
barefoot. Secure hair so it is
above shoulder level.
3. Cutting attachment
guard
This guard is intended to pre-
vent objects from being thrown
towards the operator and
to protect the operator from
unintentionel contact with the
cutting attachment.
FIRST AID KIT
A first aid kit should be carried
by operators of the edger.

SAFETY INSTRUCTIONS
4. Vibration damping
system
5. Muffler
The muffler is designed to
give the lowest possible noise
level and to direct the engineʼs
exhaust fumes away from the
operator. Mufflers equipped
with a catalytic converter are
also designed to reduce the
hazardous substances in the
exhaust fumes.
Your machine is equipped with
a vibration damping system,
which is designed to give as
vibration-free and comfortable
use as possible.
The use of incorrect cutting
equipment increases the level
of vibration.
In countries that have a warm
and dry climate the risk of fire
is obvious. We have therefore
fitted certain mufflers with a
spark arrest screen. Make sure
that your muffler is fitted with
this kind of screen.
The machineʼs vibration damp-
ing system reduces the trans-
fer of vibrations between the
engine unit/cutting equipment
and the machineʼs handle unit.
It is extremely important that
the instructions for checking,
maintaining and servicing the
muffler are followed. (See the
section “Control, maintenance
and service of the machine's
safety equipment”).
WARNING!
Over exposure to vibrations can result in
blood-vessel or nerve injury to persons suf-
!
fering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are “numbness”, lack of
feeling, “tickling”, “pricking”, “pain”, lack of
or a reduction in normal strength, changes in
the colour of the skin or its surfaces. These
symptoms normally appear in the fingers,
hands or wrists.
WARNING!
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!
!
!
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and after
stopping. This also applies at idling speeds.
Contact can result in burns to the skin. Be
observant to the risk of fire!
6. Cutting equipment
The blade is designed and
processed to withstand loads
that edging of a lawn involves.
7. Locking nut
The locking nut secures
the cutting equipment on
the output shaft.

Control, maintenance and service of
the machineʼs safety equipment
• Ensure that the guard is un-
damaged and is not cracked.
IMPORTANT INFORMATION
• Replace the guard if it has
been exposed to impact or is
cracked.
• All service and repairs to the machine require special
training.
• This applies especially to the machineʼs safety
equipment. If the machine does not meet any of the
controls listed below you should contact your serv-
ice workshop.
• Always use the prescribed
blade and guard combination,
see chapter "Technical data".
• The purchase of one of our products guarantees that
professional repair and servicing will be carried out
on it. If the point of purchase is not one of our serv-
icing dealers, please ask for details of the closest
service workshop.
1. Throttle trigger
lock
4. Vibration damping
system
• Check that the throttle is
locked in the “idling position”
when the throttle trigger lock
is in its original position.
• Check the vibration damping
element regularly for material
cracks and distortion.
• Check that the vibration
damping element is undam-
aged and securely attached.
• Press in the throttle trigger
lock and make sure it returns
to its original position when
released.
• Ensure that the throttle and
throttle trigger lock move eas-
ily and that their return spring
systems function.
5. Muffler
• See section "Start". Start
the machine and apply full
throttle. Release the throttle
and check that the cutting
equipment stops and remains
at a standstill. If the cutting
equipment rotates with the
throttle in the idling position
then the carburettorʼs idling
setting must be checked. See
chapter “Maintenance”.
1. Never use a machine that
has a defective muffler.
2. Check regularly that the
muffler is secure.
3. If your muffler is fitted
with a spark arrest screen
then it should be cleaned
regularly. A blocked
#
screen leads to the engine
overheating with serious
damage as a result. Never
use a muffler with a detec-
tive spark arrest screen.
2. Stop switch
• Start the engine and make
sure that the engine stops
when the stop switch is
moved to the stop position.

SAFETY INSTRUCTIONS
General working instructions
Basic working techniques
Safety instructions while working
IMPORTANT INFORMATION
• This section takes up the basic safety precautions for
working with the edger.
• Always ensure you have a
safe and firm foothold.
• If you encounter a situation where you are uncertain
how to proceed you should ask an expert. Contact your
dealer or your service workshop.
• Always hold the machine with
both hands. Hold the ma-
chine of the right-hand side
your the body.
• Avoid all usage which you consider to be beyond your
capability.
Basic safety precautions
• Make sure your hands and
feet do not come into con-
tact with the blade when the
engine is running.
1. Observe your surroundings:
• To ensure that people, animals or other things cannot affect
your control of the machine.
• When the engine is switched
off, keep your hands and feet
away from the blade until it
has stopped.
• To ensure that the above mentioned do not come into contact
with the cutting equipment or objects that can be thrown by
the cutting equipment.
• NOTE! Never use a machine without the possibility of calling
for help in the event of an accident.
• Always cut edges at full throt-
tle.
2. Avoid usage in unfavour-
able weather conditions.
For example, thick fog,
heavy rain, strong winds
or extreme cold, etc.
• Always keep the blade close to the ground.
• Always drop to idling speed after each working operation.
Longer periods running at full throttle without loading the
engine (that is without resistance, which the engine feels from
the cutting equipment when trimming) can lead to serious
engine damage.
To work in bad weather
conditions is tiring and can
create dangerous cir-
cumstances, e.g. slippery
surfaces.
• Be especially careful when pulling the edger towards you dur-
ing work.
• If heavy vibrations occur, stop the engine. Remove the spark
plug cable from the spark plug. Check that the machine is not
damaged. Repair any damage.
3. Make sure you can walk
and stand safely. Look
out for any obstacles with
unexpected movement
(roots, stones, branches,
pits, ditches, etc.). Take
great care when working
on sloping ground.
WARNING!
Sometimes grass and stones can collect in
!
the blade guard and blade. Always stop the
engine when cleaning.
WARNING!
Beware of thrown objects. Always wear eye
protection. Never lean over the blade guard.
Stones rubbish etc. can be thrown up into the
eyes resulting in blindness or other serious
injury.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be outside the safety zone of 15 me-
ters (50 feet). Stop the machine immediately if
anyone approaches.
!
4. The engine should be switched off before moving.
5. Never put the machine down with the engine running un-
less you have good sight of it.

FUEL HANDLING
Fuel mixture
Mixture
NOTE!
The edger is fitted with two-stroke engines and must always
be run on a mixture of petrol and two-stroke oil. To ensure
the correct mixture proportions it is important to measure the
quantity of oil accurately. When mixing small amounts of fuel
small discrepancies in the amount of oil have a great bearing on
the proportions of the fuel mixture.
• Always mix petrol and oil in a clean container intended for
petrol.
• Always start by filling half the quantity of petrol required. Then
add the entire oil quantity. Mix (shake) the fuel mixture. Fill the
remaining quantity of petrol.
• Mix (shake) the fuel mixture carefully before filling in the
machineʼs fuel tank.
WARNING!
Always provide good ventilation when
handling fuel.
• Do not mix fuel for more than max. one month's supply of fuel.
!
• If the edger is not used for a long period of time, the fuel tank
should be emptied and cleaned.
Petrol
• Always use unleaded, oil
mixed, quality petrol! (at least
90 octane). Leaded petrol
will destroy the catalytic
converter and it will no longer
serve its purpose.
WARNING!
The catalytic converter muffler becomes very
hot during and after use. This also applies
during idling. Be aware of the fire hazard,
especially when handling the saw near
flammable substances or vapours.
!
• The lowest recommended
octane rating is 90. If you
run the engine on a petrol
with a lower octane rating
than 90 so-called “knocking”
can occur. This leads
to an increased engine
temperature, which can
result in a serious engine
breakdown.
Fuelling
WARNING!
The following precautions reduce the risk of
fire:
Do not smoke or place any sources of heat in
the vicinity of the fuel.
Never refuel when the engine is running.
Always stop the engine and let it cool for a
few minutes before refuelling.
!
• When working at continuous
high revs a higher octane
rating is recommended.
Open the fuel cap slowly when fuelling so that
any over pressure is released slowly.
Tighten the fuel cap carefully after refuelling.
Always move the machine from the fuelling
area before starting.
Two-stroke oil
• For the best results use
HUSQVARNA two stroke oil,
which has been specially
developed for 2-stroke
engines. Mixing ratio 1:50
(2%).
• Clean around the fuel cap.
Contamination in the tank can
disrupt operations.
• Ensure that the fuel is
well mixed by shaking the
container before filling the
tank.
• If HUSQVARNA two stroke
oil is not available you can
use a high quality two-stroke
oil intended for air cooled
engines. Contact your dealer
when selecting an oil. Mixing
ratio: 1:33 (3%).
• Never use two-stroke oil
intended for water cooled
outboard motors, so-called
outboard motor oil.
• Never use oil intended for
four-stroke engines.

START AND STOP
Control before starting
For reasons of safety follow
these recommendations!
CHOKE: Set the choke control
in the choke position.
• 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 that the nut has not
lost its tightening capacity.
The nut lock shall have a
locking torque of at least
l.5 Nm. The nutʼs tightening
torque shall be 35-50 Nm.
• Check that the blade and
blade guard are not damaged
or cracked. Replace the
blade or blade guard if it has
been exposed to impact or if
it is cracked.
WARNING!
When the engine is started with the choke
lever in either the choke- or start throttle
position the cutting equipment starts to rotate
immediately.
!

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
Start and stop
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.
WARNING !
The complete clutch cover with shaft must be
fitted before the machine is started, otherwise
the clutch can become loose and cause
personal injury.
Always move the machine from the filling
position before starting. Place the machine
on a flat surface. Make sure the blade cannot
come into contact with any object. Make
sure that no unauthorised persons are in
the working area, otherwise there is a risk of
serious personal injury. The safety distance is
15 metres.
!
CAUTION! Do not pull the
starter cord all the way out
and do not let go of the

MAINTENANCE
Basic setting
Carburettor
Your Husqvarna product has been designed and manufactured
to specifications that reduce harmful emissions.
• The carburettor is set to its basic setting when test run at the
factory. The basic setting is richer than the optimal setting
and should be kept during the machineʼs first working hours.
Thereafter the carburettor should be finely adjusted. Fine
adjustment should be carried out by a skilled technician.
After your unit has been run 8-10 tanks of fuel the engine has
broken in. To ensure that your unit is at peak performance and
producing the least amount of harmful emissions after break
in, have your authorized servicing dealer, who has a revolution
counter at his disposal, to adjust your carburettor for optimum
operating conditions.
NOTE! If the blade rotates while the engine is idling the T screw
should be turned anticlockwise until the cutting attachment
stops.
WARNING!
The complete clutch cover with shaft must
be fitted before the machine is started,
otherwise the clutch can become loose and
cause personal injury.
Rec. idling speed: 2 700 rpm.
Rec. max speed: See ”Technical data”.
!
WARNING!
If the idling speed cannot be adjusted so
that the cutting attachment stops, contact
!
your service workshop. Do not use the
machine until it has been correctly adjusted
or repaired.
Operation
• The carburettor governs
the engineʼs speed via the
throttle. Air/fuel is mixed in
the carburettor. The air/fuel
mixture is adjustable. To
take advantage of the
Fine adjustment
• When the machine has been ”run-in” the carburettor should
be finely adjusted. The fine adjustment should be carried
out by qualified person. First adjust the L-jet, then the idling
screw T and then the H-jet.
engineʼs optimal output the
adjustment must be correct.
Conditions
• Before any adjustments are made the air filter should be clean
and the air filter cover fitted. Adjusting the carburettor while a
dirty air filter is in use will result in a leaner mixture when the
filter is finally cleaned. This can give rise to serious engine
damage.
• Turn the L and H needles carefully to the middle point
between fully screwed in and fully screwed out.
• Do not attempt to adjust the needles beyond the stops as
damage can occur.
• The setting of the
carburettor means that the
engine is adapted to local
conditions, for example, the
climate, altitude, petrol and
the type of 2-stroke oil.
• The carburettor is equipped
with three adjustment
possibilities:
• Now start the machine as set out in the start instructions and
run it warm for 10 minutes.

respectively counter-
clockwise. When the highest
speed has been found, turn
the low speed needle L 1/4
turn counter-clockwise.
NOTE! If the cutting
attachment rotates/moves in
the idling position, turn the
idling speed screw T counter-
clockwise until the cutting
attachment stops.
• The fuel quantity in relation to the air flow permitted by the
throttle opening is adjusted using the L and H-needles.
Turning the needles clockwise gives a leaner fuel mixture
(less fuel) and turning them anticlockwise gives a richer fuel
mixture (more fuel). A leaner mixture gives high revs while a
richer mixture give less revs.
• The T-screw regulates the position of the throttle while the
engine is idling. Turning the screw clockwise gives a higher
idling speed while turning it anticlockwise gives a lower idling
speed.

MAINTENANCE
Correctly adjusted carburettor
Final setting of the idling speed T
A correctly adjusted carburettor means that the machine
accelerates without hesitation and the machine 4-cycles a little
at max speed. Furthermore, the cutting attachment must not
rotate/move at idling. A too lean adjusted low speed needle L
may cause starting difficulties and bad acceleration.
A too lean adjusted high speed needle H gives lower power =
less capacity, bad acceleration and/or damage to the engine.
A too rich adjustment of the two speed needles L and H gives
acceleration problems or too low working speed.
Adjust the idling speed with
the screw T, if it is necessary
to readjust. First turn the
idle speed adjusting screw
T clockwise until the cutting
attachment starts to rotate/
move.
Then turn, counter-clockwise
until the cutting attachment
stops. A correctly adjusted idle
speed setting occurs when the
engine runs smoothly in every
position. It should also be
good margin to the rpm when
the cutting attachment starts
to rotate/move.
CAUTION! Contact your servicing dealer, if the idle speed
setting cannot be adjusted so that the cutting attachment
stops. Do not use the machine until it has been properly
adjusted or repaired.
High speed needle H
The high speed needle
H influences the power,
speed, temperature and fuel
consumption of the machine.
A too lean adjusted high
speed needle H (high speed
needle H closed too much)
gives overrevs and damages
the engine. Do not let the
machine run at full speed for
more than 10 seconds.
Turn the high speed needle
very slowly clockwise until
engine speed is reduced.
Thereafter turn the high speed
needle very slowly counter-
clockwise and stop when the
engine begins to run roughly.
Then turn the high speed
needle slowly the minimum
amount clockwise until the
engine runs smoothly.
The high speed needle H
is correctly set when the
machine ”4-cycles” a little. If
the machine ”whistles” the
setting is too lean. If there
is too much smoky exhaust
gas at the same time as the
machine ”4-cycles” much, the
setting is too rich.
NOTE! For optimum setting of the carburettor, contact a
qualified servicing dealer who has a revolution counter at
his disposal.

MAINTENANCE
Muffler with catalytic converter
Cooling system
To maintain as low an
operating temperature as
possible the engine is
equipped with a cooling
system.
A muffler fitted with a catalytic converter reduces the extent of
the following substances in the exhaust fumes:
•
Hydrocarbons (HC). Some hydrocarbons in gasoline and the
exhaust are carcinogenic.
•
•
Nitric oxides (NO). Irritating for the breathing air-ways.
Aldehydes. The most common formaldehyde, is carcinogenic
and causes hypersensitiveness.
The cooling system consists of:
1. An air intake on the starter
unit.
NOTE! The level of carbon monoxide is not reduced. This is an
odourless and extremely poisonous substance. Therefore avoid
exposure without good air circulation.
2. Cooling fins on the
flywheel.
3. Cooling fins on the cylinder
The muffler is designed to

dampen the noise level and to
direct the exhaust fumes away
from the user. The exhaust
fumes are hot and can contain
sparks, which can result in fire
if the exhaust fumes are di-
rected towards a dry or inflam-
mable material. Some mufflers
are fitted with a special spark
arrest screen. If your machine
is fitted with this type of muf-
fler then the screen should be
cleaned at least once a week.
This is done using a wire
Clean the cooling system using
a brush at least once a week,
in difficult conditions more
often.
A dirty or blocked cooling
system leads to the engine
overheating resulting in
damage to the cylinder and
piston.
brush. If the screen is dam-
aged in anyway it should be re-
placed. If the screen is blocked
this will result in the engine
overheating and damage to the
cylinder and piston,
NOTE!
Never use a machine with a
defective muffler.
Spark plug
The condition of the spark plug
is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel mixture (too
much or faulty oil).
• A dirty air filter.
0,5 mm
These factors cause deposits
on the spark plug electrode
that may result in malfunction
or starting difficulties.
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and after
!
stopping. This also applies at idling speeds.
Contact can result in burns to the skin. Be
observant to the risk of fire!
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first before
taking any other action.
WARNING!
The coating on/in the catalytic element can
be hazardous to health if consumed. Wear
protective gloves when carrying out service
work on the catalytic converter.
If the spark plug is dirty, clean it and at the same time check that
the electrode gap is 0.5 mm. The spark plug should be changed
after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.

MAINTENANCE
Lubricating the flexible drive axle
Air filter
The air filter should be cleaned
regularly removing dust and
dirt to avoid:
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to engine
parts
Inside the edgerʻs drive shaft
is a flexible drive axle. The
flexible drive axle should be
regularly lubricated after 30
hours of operation. Loosen the
two screws on the angle gear
and remove it. The flexible
drive axle is easily removed
from the shaft by taking a firm
grip on the axle end. Lubricate
the flexible drive axle over its
entire length and reinsert it in
the shaft. Turn the axle while
inserting it so that it correctly
engages in the clutch. Replace
the angle gear on the drive
axle shaft and tighten the two
screws.
• abnormal fuel consumption
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover and remove the air filter. Wash in
clean, warm soapy water. Ensure that the filter is dry before
refitting. An air filter used for a long period of time can never
be cleaned completely. Therefore it is necessary to replace the
filter from time to time with a new filter. 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 the section on “Oiling the air
filter“.
Oiling the air filter
Adjusting the edger's cutting depth
Always use HUSQVARNA
filter oil, order no. 503 47
73-01. 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 the 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
on the machine. Never use
common engine oil. This
would drain through the filter
quite quickly and collect in the
bottom.
The cutting depth should be
adjusted before starting work.
• Loosen the locking handle
(A) and rotate the guard by
moving the locking knob
forwards or backwards.
If the locking handle is
moved forwards (from the
machine) the cutting depth
is increased. If the locking
handle is moved backwards
(towards the machine) the
cutting depth is reduced.
• Adjust the cutting depth.
• Lock the locking handle.
Angle gear
The angle gear is filled
a sufficient quantity of grease
at the factory. However, before
using the machine you should
check that the angle gear is
filled to 3/4 with grease. Use
HUSQVARNA special grease.
WARNING!
Always bear the machine on the right
side of the body. Always wear protective
glasses, long trousers and heavy-duty shoes
when using the machine. Observe your
surroundings, ensure people and animals
do not come in the immediate vicinity or can
be hit by thrown objects. Apply full throttle
before the blade starts to work on the soil.
!
Normally, the grease does not
need to be changed except
when repairs are carried out.
