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.

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 fingers,
hands or wrists.
5. Muffler
The muffler is designed to give
the lowest possible noise level
and to direct the engine’s
exhaust fumes away from the
operator. Mufflers 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 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.
It is extremely important that
the instructions for checking,
maintaining and servicing the
muffler are followed. (See the
section
and service of the machine's
safety equipment”
“Control, maintenance
).
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.

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 firm 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

FUEL HANDLING
Fuel mixture
NOTE!
The edger is fitted 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 certified to
operate on unleaded
gasoline.
dling fuel.
Mixture
• Always mix gasoline and oil in a clean container intended for
fuel.
• Always start by filling 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 filling 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 certified to operate on unleaded gasoline.
WARNING!
!
The catalytic converter muffler gets very hot
during and after use. This also applies during
idling. Be aware of the fire hazard, especially
when handling the saw near flammable
substances 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!
The following precautions reduce the risk of
!
• 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.
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.
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.

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
first working hours. Thereafter the carburetor should be finely
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.

.
Fine adjustment
• When the machine has been ”run-in” the carburetor 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.
Conditions
• Before any adjustments are made the airfilter should be clean
and the airfilter cover fitted. Adjusting the carburetor while a
dirty airfilter is in use will result in a leaner mixture when the
filter is finally 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 find the highest idling
speed, turning the low speed
needle L clockwise respectively counter-clockwise. When
the highest speed has been
found, turn the low speed
needle L 1/4 turn counterclockwise.
NOTE! If the cutting attachment rotates/moves in the
idling position, turn the idling
speed screw T counterclockwise until the cutting
attachment stops.

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 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.
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 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.

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

MAINTENANCE
Muffler with catalytic converter
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.
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 muffler 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 fire
if the exhaust fumes are
directed towards a dry or
inflammable material. Some
mufflers are fitted with a
special spark arrest screen. If
your machine is fitted with this
type of muffler then the screen
should be cleaned at least
once a week. This is done
using a wire brush. If the
screen is damaged 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.
NOTE!
Never use a machine with a
defective muffler.
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 fins on the
flywheel.
3. Cooling fins on the
cylinder
4. Cylinder cover (leads cold
air onto the cylinder).
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.
Spark plug
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 filter.

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!
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.
These factors cause
deposits on the spark plug
electrode that may result
in malfunction or starting
difficulties.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
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 filter
The air filter 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 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 “
“.
filter
Oiling the air
Lubricating the flexible drive axle
Inside the edger‘s 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.
Oiling the air filter
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.
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 filled with 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.
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.
