FUEL HANDLING
Mixture
Fuel
NOTE!
• Always mix petrol and oil in a clean container intended for
petrol.
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 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
machine‘s fuel tank.
• Do not mix more than max. one month’s supply of fuel.
• If the machine 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.
!
Petrol
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 90
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.
• 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
• Clean around the fuel
cap. Contamination in
the tank can disrupt
operations.
breakdown.
• When working at
continuous high revs a
higher octane rating is
recommended.
• Ensure that the fuel is
well mixed by shaking
the container before
filling the tank.
Two-stroke oil
• For the best results use
HUSQVARNA two-
stroke oil, which has been
specially produced for

MAINTENANCE
Basic setting
Carburettor
• 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 machine’s first
working hours. Thereafter the carburettor should be finely
adjusted. Fine adjustment should be carried out by a skilled
technician.
Your Husqvarna product has been designed and manufac-
tured to specifications that reduce harmful emissions.
After your unit has been run 8-10 tanks of fuel the engine
has broken in. To ensure that your unit is at peak perform-
ance 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 carburet-
tor for optimum operating conditions.
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.
WARNING!
The complete clutch cover and gear must
be fitted before the machine is started,
otherwise the clutch may come loose and
cause injury.
Recommended idling speed is 2 700 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.
Operation
• The carburettor governs
the engine’s speed via the
throttle. Air/fuel is mixed
in the carburettor. The

• The carburettor is equipped with three adjustment possi-
bilities:
H = High speed needle
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.
L = Low speed needle
T = Idle speed adjuster screw
• 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 anti-clockwise gives a richer
fuel mixture (more fuel). A leaner mixture gives high revs
while a richer mixture give less revs.
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.
• 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.
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.

NOTE!
To maintain as low operat-
ing temperature as possible
the engine is equipped with
a cooling system.
Some mufflers are fitted with catalytic converters. See “Techni-
cal data” to find out if your machine is equipped with a
catalytic converter.
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 directed
towards a dry and inflam-
mable material. Some
mufflers are equipped with a
special spark arrest screen. If
your machine is fitted with
this type of screen it should
be cleaned regularly. This is
done using a wire brush. On
mufflers without a catalytic
converter the screen should
be cleaned weekly, or

mufflers fitted with a
catalytic converter the
screen should be checked
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
resulting in damage to the
cylinder and piston. Also see
under “Maintenance”.
NOTE!
Never use a machine with a

dust and dirt to avoid:
There is a grease plug on the
gearbox (A). Remove the
plug and insert a 4-5 cm
string from the tube of
grease supplied with the
hedge trimmer. This should
be carried out after approxi-
mately every 20 working
hours. Use Husqvarna
special grease,
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel consump-
tion
No 503 98 96-01.
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
The lubricant in the gearbox
does not normally need to
be replaced other than with
repair.

Cleaning the air filter
Dismantle the air filter cover (B) and remove the air filter.
Wash in clean, warm soapy water. Ensure that the filter is dry
before refitting.
Lubrication
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.
Always lubricate the blade
runners with special grease
531 00 60-74 (UL 21)
before use.
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.
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
A
first before taking other
action.
The spark plug is accessed
from under the cylinder
cover, which is removed by
loosening the four bolts (A).
If the spark plug is dirty,
clean it and at the same time
A
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.
0,5 mm
NOTE! Always use the
recommended type of spark
plug. An incorrect spark
plug can damage the
cylinder/piston.
