Operation
Introduction
WARNING: Before you operate the
product, you must read and understand the
safety chapter.
Fuel
This product has a two-stroke engine.
CAUTION: Incorrect type of fuel can
result in engine damage. Use a mixture of
gasoline and two-stroke oil.
Premixed fuel
• Use Husqvarna premixed alkylate fuel for best
performance and extension of the engine life. This
fuel contains less harmful chemicals compared
to regular fuel, which decreases harmful exhaust
fumes. The quantity of remains after combustion is
lower with this fuel, which keeps the components of
the engine more clean.
To mix fuel
Gasoline
• Use good quality unleaded gasoline with a maximum
of 10% ethanol contents.
CAUTION: Do not use gasoline with
an octane grade less than 90 RON/87
AKI. Use of a lower octane grade can
cause engine knocking, which causes
engine damages.
Two-stroke oil
• For best results and performance use Husqvarna
two-stroke oil.
• If Husqvarna two-stroke oil is not available, use a
two-stroke oil of good quality for air-cooled engines.
Speak to your servicing dealer to select the correct
oil.
CAUTION: Do not use two-stroke
oil for water-cooled outboard engines,
also referred to as outboard oil. Do not
use oil for four-stroke engines.

2% (50:1)
5 0.10
10 0.20
15 0.30
20 0.40
CAUTION: Small errors can influence
the ratio of the mixture drastically when you
mix small quantities of fuel. Measure the
quantity of oil carefully and make sure that
you get the correct mixture.
1. Fill half the quantity of gasoline in a clean container
for fuel.
2. Add the full quantity of oil.
3. Shake the fuel mixture.
4. Add the remaining quantity of gasoline to the
container.
5. Carefully shake the fuel mixture.
CAUTION: Do not mix fuel for more
than 1 month at a time.
To fill the fuel tank
WARNING: Obey the procedure that
follows for your safety.
1. Stop the engine and let the engine become cool.
2. Clean the area around the fuel tank cap.
3. Shake the container and make sure that the fuel is
fully mixed.
4. Remove the fuel tank cap slowly to release the
pressure.
5. Fill the fuel tank.
CAUTION: Make sure that there is
not too much fuel in the fuel tank. The
fuel expands when it becomes hot.
6. Tighten the fuel tank cap carefully.
7. Clean fuel spillage on and around the product.
8. Move the product 3 m/10 ft or more away from the
refueling area and fuel source before you start the
engine.
Note: To see where the fuel tank is on your product,

To trim the grass
1. Hold the trimmer head immediately above the
ground at an angle. Do not push the trimmer line
into the grass.
2. Decrease the length of the trimmer line by 10-12
cm / 4-4.75 in.
3. Decrease the engine speed to decrease the risk of
damage to plants.
4. Use 80 % throttle when you cut grass near objects.
To clear grass with a grass blade
1. Grass blades and grass cutters must not be used on
woody stems.
2. A grass blade is used for all types of tall or coarse
grass.
3. The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left
is the clearing stoke and the movement from left-to-
right is the return stoke. Let the left-hand side of the
blade (between 8 and 12 o'clock) do the cutting.
12 941 - 008 - 24.06.2022
4. if the blade is angled to the left when clearing grass,
the grass will collect in a line, which makes it easier
to collect, e.g. by raking.
5. Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stoke and stand
firmly again.
6. Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the ground.
7. Reduce the risk of material wrapping around the
blade by always work at full throttle and avoid the
previously cut material during the return stoke.
8. Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the
cut material.
To cut the grass
1. Make sure that the trimmer line is parallel to the
ground when you cut the grass.
2. Do not push the trimmer head to the ground. This
can cause damage to the product.
3. Move the product from side to side when you cut
grass. Use full speed.
To sweep the grass
The airflow from the rotating trimmer line can be used to
remove cut grass from an area.
1. Hold the trimmer head and the trimmer line parallel
to the ground and above the ground.
2. Apply full throttle.
3. Move the trimmer head from side to side and sweep
the grass.
WARNING: Clean the trimmer head
cover each time you assemble new trimmer
line to prevent unbalance and vibrations in
the handles. Also do a check of the other
parts of the trimmer head and clean it if
necessary.
Grass trimmer head
• Make sure that you wind the grass trimmer line
tightly and equally around the drum to decrease the
vibration.
• Use only the approved grass trimmer heads and
grass trimmer lines. Refer to
Accessories on page
19
.
• Use a correct length of the grass trimmer line. A long
grass trimmer line uses more engine power than a
short grass trimmer line.
• Make sure that the cutter on the cutting attachment
guard is not damaged.
• Soak the grass trimmer line in water for 2 days
before you attach the grass trimmer line to the
product. This increases the life of the grass trimmer
line.
• Refer to the instructions for the cutting attachment to
use the correct procedure to load the cord and the
correct cord diameter.

To adjust the idle speed
Make sure that the air filter is clean and the air filter
cover is attached before you adjust the idle speed.
1. Turn the idle speed screw T, which is identified with
a "T" mark, clockwise until the cutting attachment
starts to rotate.

2. Turn the idle speed screw T, which is identified
with a "T" mark, counterclockwise until the cutting
attachment stops.
3. The idle speed must be below the speed when the
cutting attachment starts to rotate. The idle speed
is correct when the engine operates smoothly in all
positions.
To do maintenance on the spark
arrester screen
• Use a wire brush to clean the spark arrester screen.
To clean the cooling system

1Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/
EC. Reported sound power level for the product has been measured with the original cutting attachment
that gives the highest level. The difference between guaranteed and measured sound power is that the
guaranteed sound power also includes dispersion in the measurement result and the variations between
different products of the same model according to Directive 2000/14/EC.
2Reported data for equivalent sound pressure level for the product has a typical statistical dispersion (standard
deviation) of 1 dB (A).
3Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s2.
