you stop the engine, so that you can hear any
noises or warning signals.

The machine’s safety equipment

This section describes the machine’s safety equipment, its func­tion 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.)

WARNING!
Never use a machine with defective safety

!

1. Throttle trigger
lock

The throttle trigger lock is
designed to prevent the throttle
from accidentally being en­gaged. 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 independ­ent return spring systems.
This means that the throttle
is automatically locked in the
“idling” position.

equipment. Follow the control, maintenance
and service instructions described in this
section.

EYE PROTECTION
Blows from branches or
objects thrown by the rotating
cutting equipment can damage
the eyes.

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 heavy­duty long pants. Do not wear
jewellery, shorts, sandals or go
barefoot. Secure hair so it is
above shoulder level.

SAFETY INSTRUCTIONS

4. Vibration damping
system

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.

The machine’s vibration damp­ing system reduces the trans­fer of vibrations between the
engine unit/cutting equipment
and the machine’s handle unit.

WARNING!
Over exposure to vibrations can result in

!

blood-vessel or nerve injury to persons suf­fering 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 fi ngers,
hands or wrists.

5. Muffl er

The muffl er is designed to
give the lowest possible noise
level and to direct the engine’s
exhaust fumes away from the
operator. Muffl ers equipped
with a catalytic converter are
also designed to reduce the
hazardous substances in the
exhaust fumes.

In countries that have a warm
and dry climate the risk of fi re
is obvious. We have therefore
fi tted certain muffl ers with a
spark arrest screen. Make sure
that your muffl er is fi tted with
this kind of screen.

It is extremely important that
the instructions for checking,
maintaining and servicing the
muffl er are followed. (See the
section “Control, maintenance

and service of the machine's
safety equipment”).

WARNING!
The exhaust fumes from the engine are hot

!

and may contain sparks which can start a
fi re. Never start the machine indoors or near
combustible material!

WARNING!
Muffl ers fi tted 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 fi re!

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.

SAFETY INSTRUCTIONS

General working instructions

IMPORTANT INFORMATION

• This section takes up the basic safety precautions for
working with the edger.

• 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.

Basic safety precautions

1. Observe your surroundings:

• To ensure that people, animals or other things cannot affect
your control of the machine.

• 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.

Basic working techniques

Safety instructions while working

• Always ensure you have a
safe and fi rm foothold.

• Always hold the machine with
both hands. Hold the ma­chine of the right-hand side
your the body.

• Make sure your hands and
feet do not come into con­tact with the blade when the
engine is running.

• When the engine is switched
off, keep your hands and feet
away from the blade until it
has stopped.

• NOTE! Never use a machine without the possibility of calling

for help in the event of an accident.

2. Avoid usage in unfavour­able weather conditions.
For example, thick fog,
heavy rain, strong winds
or extreme cold, etc.
To work in bad weather
conditions is tiring and can
create dangerous cir­cumstances, e.g. slippery
surfaces.

3. Make sure you can walk
and stand safely. Look
out for any obstacles with
unexpected movement

FUEL HANDLING

Fuel mixture

NOTE!
The edger is fi tted with two-stroke engines and must always
be run on a mixture of gasoline 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 has a great bearing on
the proportions of the fuel mixture.

WARNING!
Always provide good ventilation when han-

!

Gasoline

NOTE!

Always use high grade
unleaded oil mixed gasoline
(minimum 87 RON). Leaded
fuel will destroy the catalytic
converter and it will no longer
serve its purpose.

• This engine is certifi ed to
operate on unleaded gaso­line.

dling fuel.

Mixture

• Always mix gasoline and oil in a clean container intended for
fuel.

• Always start by fi lling half the quantity of gasoline required.
Then add the entire oil quantity. Mix (shake) the fuel mixture.
Fill the remaining quantity of gasoline.

• Mix (shake) the fuel mixture carefully before fi lling in the
machine‘s fuel tank.

• Do not mix more than max. one month’s supply of fuel.

• If the clearing saw is not used for a long period of time, the
fuel tank should be emptied and cleaned.

• This engine is certifi ed to operate on unleaded gasoline.

WARNING!

!

The catalytic converter muffl er gets very hot
during and after use. This also applies during
idling. Be aware of the fi re hazard, especially
when handling the saw near fl ammable sub-
stances or vapours.

Fuelling

• The lowest recommended
octane rating is 87. If you run
the engine on lower octane
rating than 87 so-called
“knocking“ can occur. This
leads to an increased engine
temperature, which can result
in a serious engine break­down.

• When working at continuous
high revs a higher octane rat­ing is recommended.

Two-stroke oil

• For the best results use
HUSQVARNA two-stroke
oil, which has been specially
developed for two-stroke
engines.

Mixing ratio 1:50 (2%).

• Never use two-stroke oil
intended for water cooled
outboard motors, so-called
outboard motor oil.

WARNING!

!

• Clean around the fuel
cap. Contamination in the
tank can disrupt opera­tions.

• Ensure that the fuel is
well mixed by shaking the
container before fi lling the
tank.

The following precautions reduce the risk of
fi re:
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.
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 place
before starting.

• Never use oil intended of
four-stroke engines.

14 – English

• The carburetor governs
the engine‘s speed via the
throttle. Air/fuel is mixed in
the carburetor. The air/fuel
mixture is adjustable. To take
advantage of the engine‘s
optimal output the adjustment
must be correct.

• The setting of the carbure­tor means that the engine is
adapted to local conditions,
for example, the climate, alti­tude, gasoline and the type of
2-stroke oil.

• The carburetor is equipped
with three adjustment pos­sibilities:

L = Low speed needle
H = High speed needle
T = Idle speed adjuster

screw

• The fuel quantity in relation to
the air fl ow 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 anti-clockwise 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 anti-clockwise gives a lower idling
speed.

The complete clutch cover with shaft must
be fi tted before the machine is started, oth-
erwise the clutch can become loose and
cause personal injury.

Basic setting

• The carburetor is set to its basic setting when test run at the
factory. The basic setting should be kept during the machine‘s
fi rst working hours. Thereafter the carburetor should be fi nely
adjusted. Fine adjustment should be carried out by a skilled
technician.

NOTE! If the cutting attachment rotates/moves while the engine
is idling the T-screw should be turned anti-clockwise until the
cutting attachment stops.

Rec. idling speed: 2700 rpm.

Recommended 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.

Fine adjustment

• When the machine has been ”run-in” the carburetor should
be fi nely adjusted. The fi ne adjustment should be carried
out by qualifi ed person. First adjust the L-jet, then the idling
screw T and then the H-jet.

Conditions

• Before any adjustments are made the airfi lter should be clean
and the airfi lter cover fi tted. Adjusting the carburetor while a
dirty airfi lter is in use will result in a leaner mixture when the
fi lter is fi nally cleaned. This can give rise to serious engine
damage.

• Carefully turn the L and H needle to the mid point between
fully turned in and fully turned out.

• Do not attempt to adjust the needles beyond the stops as

damage can occur.

• Now start the machine according to the starting instructions
and run it warm for 10 minutes.

NOTE! If the cutting attachment rotates/moves the T screw
should be turned anti-clockwise until the cutting attachment
stops.

Low speed needle L

Try to fi nd 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.
NOTE! If the cutting attach­ment rotates/moves in the
idling position, turn the idling
speed screw T counter-clock­wise until the cutting attach­ment stops.

MAINTENANCE

Final setting of the idling speed T

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.

Correctly adjusted carburetor

A correctly adjusted carburetor 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 diffi culties 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.

High speed needle H

The high speed needle H
infl uences 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 counter­clockwise 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.

H

NOTE! For optimum setting of the carburetor, contact a
qualifi ed servicing dealer who has a revolution counter at
his disposal.

MAINTENANCE

Muffl er with catalytic converter

A muffl er fi tted 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.

NOTE! The level of carbon monoxide is not reduced. This is an
odourless and extremely poisonous substance. Therefore avoid
exposure without good air circulation.

The muffl er is also 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 fi re
if the exhaust fumes are di­rected towards a dry or infl am-
mable material. Some muffl ers
are fi tted with a special spark
arrest screen. If your machine
is fi tted with this type of muf-
fl er then the screen should be
cleaned at least once a week.
This is done using a wire
brush. If the screen is dam-

aged in any way it should
be replaced. If the screen is

blocked this will result in en­gine overheating and damage
to the cylinder and piston.

Cooling system

To maintain as low operating
temperature as possible the
engine is equipped with a cool­ing system.
The cooling system consists
of:

1. An air intake on the starter
unit.

2. Cooling fi ns on the fl y-
wheel.

3. Cooling fi ns on the cylin-
der

4. Cylinder cover (leads cold
air onto the cylinder).

Clean the cooling system using
a brush at least once a week,
in diffi cult conditions more
often.

A dirty or blocked cooling
system leads to the engine
overheating resulting in
damage to the cylinder and
piston.

Spark plug

NOTE!

Never use a machine with a
defective muffl er.

WARNING!
Muffl ers fi tted 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 fi re!

WARNING!
The coating on/in the catalytic element can
be hazardous to health if consumed. Wear
gloves when carrying out service work on the
catalytic converter.

The condition of the spark
plug is affected by:

• An incorrect carburetor

setting.

• An incorrect fuel mixture

(too much or faulty oil).

• A dirty air fi lter.

These factors cause
deposits on the spark plug
electrode that may result
in malfunction or starting
diffi culties.

If the machine is low on power, diffi cult to start or runs
poorly while idling always check the spark plug fi rst.

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

Air fi lter

The air fi lter should be cleaned
regularly removing dust and
dirt to avoid:

• carburetor malfunction

• starting problems

• reduced engine power

• unnecessary wear to engine
parts

• abnormal fuel consumption

Clean the fi lter after every 25
hours or more regularly if oper­ating conditions are exception­ally dusty.

Cleaning the air fi lter

Dismantle the air fi lter cover and remove the air fi lter. Wash in
clean, warm soapy water. Ensure that the fi lter is dry before
refi tting. An air fi lter used for a long period of time can never
be cleaned completely. Therefore it is necessary to replace the
fi lter from time to time with a new fi lter. A damaged air fi lter must
always be replaced.

If the machine is used in dusty conditions the air fi lter
should be soaked in oil, see the section on “Oiling the air
fi lter“.

Lubricating the fl exible drive axle

Inside the edger‘s drive shaft
is a fl exible drive axle. The
fl exible drive axle should be
regularly lubricated after 30
hours of operation. Loosen
the two screws on the angle
gear and remove it. The
fl exible drive axle is easily
removed from the shaft by
taking a fi rm grip on the axle
end. Lubricate the fl exible
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.

Oiling the air fi lter

Always use HUSQVARNA
fi lter oil, order no. 503 47
73-01. The fi lter oil contains
a solvent to make it spread
evenly through the fi lter.
You should therefore avoid
skin contact. Put the fi lter in
a plastic bag and the pour
the fi lter oil over it. Knead
the plastic bag to distribute
the oil. Squeeze the excess
oil out of the fi lter inside the
plastic bag and pour off the
excess before fi tting the fi lter
on the machine. Never use
common engine oil. This
would drain through the fi lter
quite quickly and collect in the
bottom.

Adjusting the edger‘s cutting depth

The cutting depth should be
adjusted before starting work.

• Loosen the locking handle
(A) and rotate the guard by
moving the locking handle
backwards or forwards. 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.

A

Angle gear

The angle gear is fi lled with a
suffi cient quantity of grease at
the factory. However, before
using the machine you should
check that the angle gear is
fi lled to 3/4 with grease. Use
HUSQVARNA special grease.

Normally, the grease does not
need to be changed except
when repairs are carried out.

!

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.
