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

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.

Min 3m (10ft)

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 To adjust chain lubrication on page 22.

• 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.

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).

A B

When you sharpen the cutter, think about the following:

- Filing angle.

It is not easy to sharpen a saw chain correctly without the correct equipment. Use Husqvarna file gauge. This will help you to keep maximum cutting performance.

Note: Refer to To sharpen the cutters on page 21 for information about sharpening of the saw chain.

To sharpen the cutters

1. Use a round file and a file gauge to sharpen the cutting teeth.

Three technical illustrations of mechanical components: a pipette, a plastic component, and a tool (no text or symbols)

Note: Refer to Filing equipment and filing angles on page 25 for information about which file and gauge that Husqvarna recommends for your saw chain.

1. Apply the file gauge correctly on to the cutter. Refer to the instruction supplied with the file gauge.
2. Move the file from the inner side of the cutting teeth and out. Decrease the pressure on the pull stroke.

1. Remove material from one side of all the cutting teeth.
2. Turn the product around and remove material on the other side.
3. Make sure that all cutting teeth are the same length.

General information about how to adjust the depth gauge setting

The depth gauge setting (C) decreases when you sharpen the cutting tooth (A). To keep maximum cutting performance you must remove filing material from the depth gauge (B) to receive the recommended depth gauge setting. Refer to Technical data on page 24 for instructions about how to receive the correct depth gauge setting for your saw chain.

A B C

To adjust the depth gauge setting

Before you adjust the depth gauge setting or sharpen the cutters, refer to General information about how to sharpen the cutters on page 20, for instructions. We recommend you to adjust the depth gauge setting after each third operation that you sharpen the cutting teeth.

We recommend that you use our depth gauge tool to receive the correct depth gauge setting and bevel for the depth gauge.

Two mechanical tools: a tool with a textured handle and a clamped device (no text or symbols visible)

1. Use a flat file and a depth gauge tool to adjust the depth gauge setting. Only use Husqvarna depth gauge tool to get the correct depth gauge setting and bevel for the depth gauge.
