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

CAUTION: Do not use gasoline with an

octane number less than 90 RON (87 AKI).

This can cause damage to the product.

CAUTION: Do not use gasoline with more

than 10% ethanol concentration (E10). This

can cause damage to the product.

CAUTION: Do not use leaded gasoline. This

can cause damage to the product.

• Always use new unleaded gasoline with a minimum

octane number of 90 RON (87 AKI) and with less

than 10% ethanol concentration (E10).

• Use gasoline with a higher octane number if you

frequently use the product at continuously high

engine speed.

• Always use a good quality unleaded gasoline/oil

mixture.

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.

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

1. Clean the area around the fuel tank cap.

2. Shake the container and make sure that the fuel is

fully mixed. Use a fuel container with an anti-spill

valve.

3. Fill the fuel tank.

4. Tighten the fuel tank cap carefully.

5. Move the product 3 m (10 ft) or more away from the

refueling area and fuel source before starting.

703 - 005 - 20.10.2020

CAUTION: Contamination in the tanks

causes malfunction. Clean the fuel tank and

chain oil tank regularly and replace the fuel

filter one time a year or more.

To do a run-in

• During the first 10 hours of operation, do not apply

full throttle without load for extended periods.

To use the correct chain oil

WARNING: Do not use waste oil, which can

cause injury to you and the environment.

Waste oil also causes damage to the oil

pump, the guide bar and the saw chain.

WARNING: The saw chain can break if the

lubrication of the cutting equipment is not

sufficient. Risk of serious injury or death to

the operator.

WARNING: This product has a function that

lets the fuel run out before the chain oil. Use

the correct chain oil for this safety function to

operate correctly. Speak to your servicing

dealer when you select your chain oil.

Note: This product has an automatic chain lubrication

system. You can also adjust the oil flow. Refer to

adjust chain lubrication on page 23

• Use Husqvarna chain oil for maximum saw chain life

and to minimise environmental damage. If

Husqvarna chain oil is not available, we recommend

you to use a standard chain oil.

• Use a chain oil with good adherence to the saw

chain.

• Use a chain oil with correct viscosity range that

agrees with the air temperature.

CAUTION:

If the oil is too thin, it runs out

before the fuel. In temperatures below

0°C/32°F some chain oils become too

thick, which can cause damage to the oil

pump components.

• Use the recommended cutting equipment. Refer to

Accessories on page 25

To use the product

• Hold the product as close to your body as possible to

get the best balance. Use the harness to support the

weight of the machine and make it easier to handle.

• Make sure that the tip does not touch the ground.

• Do not rush the work, but work steadily until all the

branches have been cut back cleanly.

• Always slow the engine to idle speed after each

working operation. Long periods at full throttle

without any load on the engine can lead to serious

engine damage.

• Always work at full throttle.

• Whenever possible position yourself so that you can

make the cut at right angles to the branch.

• Do not work with the shaft held straight out in front of

you as this increases the apparent weight of the

cutting attachment.

• Cut large branches in sections so that you have

better control over where they fall.

703 - 005 - 20.10.2020

• Never cut through the swelling at the root of the

branch as this will slow down healing and increase

the risk of fungal attack.

• Use the stop at the base of the cutting head to

provide support during cutting. This will help prevent

the cutting attachment from bouncing on the branch.

• Make an initial cut on the underside of the branch

before cutting through the branch. This will prevent

tearing of the bark, which could lead to slow healing

and cause permanent damage to the tree. The cut

should not be deeper than ⅓ of the branch thickness

to prevent jamming. Keep the chain running while

you withdraw the cutting attachment from the branch

to prevent it jamming.

16 703 - 005 - 20.10.2020

The idle speed is correct when the engine operates

smoothly in all positions. The idle speed must be below

the speed when the saw chain starts to turn.

WARNING: If the saw chain does not stop

when you adjust the idle speed, turn to your

nearest servicing dealer. Do not use the

product until it is correctly adjusted or

repaired.

Note: Refer to

Technical data on page 24

for the

recommended idle speed.

To do maintenance on the muffler

The muffler decreases the noise level and directs the

exhaust gases away from the operator.

WARNING: Mufflers that have catalytic

converters get very hot during operation and

will stay hot for some time after you stop the

product. This also applies at idle speed. If

you touch the product it can result in burns

to the skin. Think about of the risk of fire.

1. Stop the product and let it cool down.

2. Remove the cover to the muffler.

3. Remove the screw holding the spark arrestor mesh.

4. Clean the spark arrestor mesh if it is blocked or

replace it if it is damaged.

CAUTION:

The spark arrestor mesh must be

replaced if it is damaged. Do not use a

product if the spark arrestor mesh on the

muffler is missing or defective.

CAUTION: If the spark arrestor mesh is

frequently blocked it can be a sign that

performance of the catalytic converter is

decreased. Turn to your servicing dealer to

examine the muffler. A blocked spark

arrestor mesh will cause overheating and

result in damage to the cylinder and piston.

Cooling system

The product has a cooling system to keep the operation

temperature as low as possible.

Clean the components of the cooling system with a

brush weekly or more frequently in rougher conditions. A

dirty or blocked cooling system makes the product too

hot which causes damage to the piston and cylinder.

The cooling system has the following components:

1. Air intake on the starter.

2. Fins on the flywheel.

3. Cooling fins on the cylinder.

4. Cylinder cover.

5. Muffler cover.

6. Muffler plate.

To examine the spark plug

CAUTION:

Always use the recommended

spark plug type, refer to

Technical data on

page 24

. Incorrect spark plug type can

cause damage to the product.

• Examine the spark plug if the engine is low on

power, is not easy to start or does not operate

correctly at idle speed.

• To decrease the risk of unwanted material on the

spark plug electrodes, obey these instructions:

a) Make sure that the idle speed is correctly

adjusted.

b) Make sure that the fuel mixture is correct.

c) Make sure that the air filter is clean.

703 - 005 - 20.10.2020

• If the spark plug is dirty, clean it and make sure that

the electrode gap is correct, refer to

Technical data

on page 24

• Replace the spark plug if it is necessary.

Air filter

Remove dust and dirt from the air filter to keep it clean

and prevent these problems:

• Carburetor malfunctions.

• Problems when you start the product.

• Loss of engine power.

• Increased wear to engine parts.

• Too much fuel consumption.

To clean the air filter

CAUTION: A air filter that is damaged, very

dirty or soaked with fuel must always be

replaced.

If you use an air filter for a long time it cannot be fully

cleaned. Replace the air filter with a new one at regular

intervals.

1. Move the choke lever up, to close the choke valve.

2. Remove the air filter cover and remove the air filter.

3. Clean the air filter with warm soap water.

4. Replace the air filter if it is too dirty to fully clean it.

Always replace a damaged air filter.

5. Also clean the inner surface of the filter cover. Use

air or a brush.

6. Do a check of the rubber sealing surface. Replace

the filter on the rubber seal if it is damaged.

7. Make sure that the filter is dry before you assemble

it.

Two piece-shaft

Apply grease to the end of the drive shaft after each 30

hours of operation. There is a risk that the drive shaft

ends (splined coupling) on models with two-piece shafts

will seize if they are not lubricated regularly.

To check the chain drive sprocket

1. Regularly check the degree of wear on the drive

sprocket. Replace if wear is excessive.

703 - 005 - 20.10.2020

To examine the cutting equipment

1. Make sure that there are no cracks in rivets and links

and that no rivets are loose. Replace if it is

necessary.

2. Make sure that the saw chain is easy to bend.

Replace the saw chain if it is rigid.

3. Compare the saw chain with a new saw chain to

examine if the rivets and links are worn.

4. Replace the saw chain when the longest part of the

cutting tooth is less than 4 mm/0.16 in. Also replace

the saw chain if there are cracks on the cutters.

To do a check of the guide bar

1. Make sure that the oil channel is not blocked. Clean

if it is necessary.

2. Examine if there are burrs on the edges of the guide

bar. Remove the burrs using a file.

3. Clean the groove in the guide bar.

4. Examine the groove in the guide bar for wear.

Replace the guide bar if it is necessary.

5. Examine if the guide bar tip is rough or very worn.

6. Make sure that the bar tip sprocket turns freely and

that the lubricating hole in the bar tip sprocket is not

blocked. Clean and lubricate if it is necessary.

7. Turn the guide bar daily to extend its life cycle.

Information about the guide bar and saw chain

WARNING:

Use protective gloves when you

use or do maintenance on the saw chain. A

saw chain that does not move can also

cause injuries.

Replace a worn or damaged guide bar or saw chain with

the guide bar and saw chain combination recommended

by Husqvarna. This is necessary to keep the safety

functions of the product. Refer to

Accessories on page

, for a list of replacement bar and chain

combinations that we recommend.

703 - 005 - 20.10.2020

• Guide bar length, in/cm. Information about the guide

bar length can usually be found on the rear end of

the guide bar.

• Number of teeth on bar tip sprocket (T).

• Chain pitch, in. The distance between the drive links

of the saw chain must align with the distance of the

teeth on the bar tip sprocket and drive sprocket.

PITCH =

• Number of drive links. The number of drive links is

decided by the type of guide bar.

• Bar groove width, in/mm. The groove width in guide

bar must be the same as the chain drive links width.

• Chain oil hole and hole for chain tensioner. The

guide bar must align with product.

• Drive link width, mm/in.

General information about how to sharpen the

cutters

Do not use a blunt saw chain. If the saw chain is blunt,

you must apply more pressure to push the guide bar

through the wood. If the saw chain is very blunt, there

will be no wood chips but sawdust.

A sharp saw chain eats through the wood and the wood

chips becomes long and thick.

The cutting tooth (A) and the depth gauge (B) together

makes the cutting part of the saw chain, the cutter. The

difference in height between the two gives the cutting

depth (depth gauge setting).

When you sharpen the cutter, think about the following:

• Filing angle.
