recommend! See chapter
“Technical data“.
7. Locking nut
• Protect your hand from
injury when assembling,
use the blade guard as
protection when tightening
with a socket spanner.
Tighten the nut by turning
against the direction of
rotation. Loosen the nut by
turning in the direction of
rotation. (NOTE! the nut
has a left-hand thread).
• Generally smaller machines require a small trimmer head
and vice versa. This is because when clearing using a cord
the engine must throw out the cord radially from the
trimmer head and also meet resistance from 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 the knife positioned on the trimmer guard is
intact. This is used to cut the cord to the correct length.
• Tighten the nut using a
socket spanner, 35 - 50
Nm (3.5 - 5 kpm).
• To increase the life of the cord it can be soaked in water for
a few days. This will make the line tougher and it will keep
longer.
NOTE!
The locking nut‘s nylon lock must not be so worn that it can
be turned by hand. The lock shall hold at least 1.5 Nm. The
nut should be replaced after it has been put on approx. 10
times.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly
and evenly around the drum, otherwise harmful
vibrations will occur.
WARNING!
Never use a machine with defective
safety equipment. The safety equipment
should be maintained as described in this
section. If your machine does not meet
any of these controls you should contact
your service workshop.
!
WARNING!
Always stop the engine before starting
work on any part of the cutting equipment.

precautions for working with the trimmer.
•
If you encounter a situation where you are
uncertain how to proceed you should ask an
expert. Contact your dealer or your service
workshop.
WARNING!
Sometimes branches, grass or wood can
get caught between the guard and cutting
equipment. Always stop the engine when
cleaning.
•
Avoid all usage which you consider to be
!
beyond your capability.
Basic safety precautions
Grass trimming using the trimmer head
1.Observe your surroundings:
• Hold the trimmer head
just above the ground at
an angle. It is the end of
the cord that carries out
the work. Let the cord
work at its own pace. Do
not press the cord into
the area to be cut.
• 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.
• NOTE! Never use a machine without the possibility of
calling for help in the event of an accident.
• 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.
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.
• Reduce the risk of
damaging plants by
shortening the cord to
10-12 cm and reducing
the engine speed.
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.
4.The engine should be switched off before moving.
5.Never put the machine down with the engine running unless
you have good sight of it.

SAFETY INSTRUCTIONS
Clearing
Trimming
• 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. NOTE! This
technique increases the
wear on the cord.
• The trimmer is ideal to
cut 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.
• 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.
• Do not allow the
trimmer head to
constantly come into
contact with the ground
during normal cutting
procedures. Constant
contact can cause damage
and wear to the trimmer
head.
• 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.
Sweeping
• The rotating cord‘s
fanning effect can be
used for quick and easy
cleaning. Hold the cord
parallel to and above the
area to be swept and
move the trimmer from
side to side.
• When cutting and
sweeping you should use
full throttle to obtain the
best results.
WARNING!
Warning for thrown objects. Always wear
protective glasses. Never lean over the
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 (50 feet). Stop the machine
!
immediately if anyone approaches.

FUEL HANDLING
Mixture
Fuel mixture
NOTE!
• Always mix gasoline and oil in a clean container intended
for fuel.
The machine is fitted with a two-stroke engine and must
always be run on a mixture of petrol and two-stroke oil. It is
important to measure the quantity of oil accurately, to ensure
the correct mixture ratio. Small discrepancies in the amount of
oil have a great bearing on the proportions of the fuel mixture
when mixing small amounts of 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.
WARNING!
Always provide good ventilation when
handling fuel.
!
• This engine is certified to operate on unleaded gasoline.
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.
!
NOTE!
Always use an oil-mixed
quality petrol (at least 87
octane). If your machine is
equipped with a catalytic
converter, (see “technical
data”) an unleaded, oil
mixed quality petrol should
always be used. A leaded
petrol will destroy the
catalytic converter.
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. 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.
• This engine is certified to
operate on unleaded
gasoline.
• 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.
• 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.
• When working at
continuous high revs a
higher octane rating is
recommended.

engine, but do not set the
choke control in the choke
position. The start throttle
position is obtained by
setting the choke control in
the choke position and then
returning it to its original
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.
• Check that the guard is
not damaged or cracked.
Replace the guard if it is
exposed to impact or is
cracked.
Stop
The engine is stopped by
switching off the ignition.
• Check that the trimmer
head and spray guard are
not damaged or cracked.
Replace the trimmer head
or spray guard if they are
exposed to impact or are
cracked.
• Never use the machine
without a guard or spray
guard nor with a defective
guard.

Functioning
• The carburettor governs
the engine speed via the
throttle trigger. In the
carburettor, air/fuel is
mixed. This air/fuel

mixture is adjustable. If
you want to take
advantage of the
maximum output of the
engine, the setting must be
corret.
Conditions
• Before any adjustments are made the airfilter should be clean
and the airfilter cover fitted. Adjusting the carburettor 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.
• The setting of the
carburettor means that the
engine is adjusted to local
conditions, for example
climate, altitude, petrol
and type of two-stroke oil.
• The carburettor has three
adjustment possibilities:
L= Low speed needle
H= High speed
adjustment screw
T= Idle speed adjustment
screw
• The fuel quantity required
in proportion to the
airflow the throttle trigger
level allows is adjusted by
means of the L- and H-
needles. Turning the
needles clockwise gives a
leaner fuel mixture (less
fuel), turning them
counter-clockwise gives a
richer fuel mixture (more
fuel). A lean mixture gives
higher rpms and a rich one
lower rpms.
• The idling speed screw T regulates the position of the
throttle lever in the idling speed position. Turn the idling
speed screw clockwise gives a higher idling speed, turn it
counter-clockwise a lower idling speed.
• 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.

Try to find the highest idling
speed, turning the low speed
needle L clockwise

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.
Correctly adjusted carburettor
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.
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 affects
the machine’s power, speed,
temperature and fuel
consumption. A too lean
adjustment on the high
speed needle H (the high
speed needle H is screwed in
too much) gives a too high
speed resulting in engine
damage. Do not allow the
engine to run at full speed
for more than 10 seconds.
Apply full throttle and turn
the high speed needle H
slowly anticlockwise until
the engine runs unevenly.
The high speed needle H is
then turned slowly clockwise
a little until the engine runs
smoothly.
Note the engine should be
run unloaded when
adjusting the high speed
H
needle. Therefore dismantle
the cutting equipment, nut,
support flange and disc drive
before adjusting the high speed needle. The high speed needle
is adjusted correctly when the machine ‘splatters’ a little . If the
machine smokes heavily at the same time as it ‘splatters’ heavily
the adjustment is too rich.
NOTE! For optimum setting of the carburettor, contact a
qualified servicing dealer who has a revolution counter at his
disposal.

NOTE!
To maintain as low opera-
ting temperature as possible
the engine is equipped with
a cooling system.
Some mufflers are fitted with a catalytic converter. See
“Technical data” to see whether you clearing saw is fitted with a
catalytic converter.
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

and cleaned monthly. If the
screen is damaged it should
be replaced. If the screen is
frequently blocked, this can
be a sign that the function
of the catalytic converter is
impaired. Contact your
dealer to inspect the muffler.
A blocked screen will cause
the engine to overheat
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
• abnormal fuel
consumption
resulting in damage to the
cylinder and piston. Also see
under “Maintenance”.
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
NOTE!
Never use a machine with a
defective muffler.
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.
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!

MAINTENANCE
Spark plug
The condition of the spark
plug is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel
mixture (too much or
faulty oil).
0,5 mm
• A dirty air filter.
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.
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 the angle gear
is repaired.
Two-part shaft
The end of the drive axle in
the lower shaft should be
lubricated with grease every
30 hours. There is a risk
that the drive axle ends
(splined coupling) on two-
part shafts jam if they are
not lubricated regularly.
