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.

10 941 - 008 - 24.06.2022

To mix gasoline and two-stroke oil

Gasoline, liter Two-stroke oil,

liter

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,

refer to

Product overview on page 2

.

2. Pull the starter rope until the engine starts.

To stop the product

• Push the stop switch to stop the engine.

Note: The stop switch automatically goes back to its

initial position.

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

• Clean the air intake (A) on the starter and the cooling

fins (B) on the cylinder with a brush.

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.
