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.

• We recommend that you use gasoline of a higher octane grade for work with continuously high rpm.

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 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 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 the chain oil flow on page 32.

• Use Husqvarna chain oil for maximum saw chain life and to prevent negative effects on the environment. 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 36.
• Remove the cap to the chain oil tank.
• Fill the chain oil tank with chain oil.
• Attach the cap carefully.

Kickback information

WARNING: A kickback can cause serious injury or death to the operator or others. To decrease the risk you must know the causes of kickback and how to prevent them.

A kickback occurs when the kickback zone of the guide bar touches an object. A kickback can occur suddenly and with large force, which throws the product in the direction of the operator.

Kickback always occurs in the cutting plane of the guide bar. Usually, the product is thrown against the operator but can also move in a different direction. It is how you use the product when the kickback occurs that causes the direction of the movement.

Illustration of a person in protective gear using a tool to lift a cylindrical object with an arrow indicating motion (no text or symbols)

A smaller bar tip radius decreases the force of the kickback.

Use a low kickback saw chain to decrease the effects of kickback. Do not let the kickback zone touch an object.

WARNING: No saw chain fully prevents kickback. Always obey the instructions.

Common questions about kickback

- Will the hand always engage the chain brake during a kickback?

No. It is necessary to use some force to push the front hand guard forward. If you do not use the force necessary, the chain brake will not be engaged. You must also hold the handles of the product stable with two hands during work. If a kickback occurs, it is possible that the chain brake does not stop the saw chain before it touches you. There are also some positions in which your hand can not touch the front hand guard to engage the chain brake. An example of this is in the felling position.

- Will the inertia release mechanism always engage the chain brake during kickback?

No. First, the chain brake must operate correctly. Refer to To do a check of the chain brake on page 23 for instructions about how to do a check of the chain brake. We recommend you to do this each time before you use the product. Second, the force of the kickback must be large to engage the chain brake. If the chain brake is too sensitive, it can engage during rough operation.

- Will the chain brake always protect me from injury during a kickback?

No. The chain brake must operate correctly to give protection. The chain brake must also be engaged during a kickback to stop the saw chain. If you are near the guide bar, it is possible that the chain brake does not have time to stop the saw chain before it hits you.

WARNING: Only you and the correct working technique can prevent kickbacks.

To calculate the felling direction

1. Examine in which direction it is necessary for the tree to fall. The goal is to fell it in a position where you can limb and cut the trunk easily. It is also important that you are stable on your feet and can move about safely.

WARNING: If it is dangerous or not possible to fell the tree in its natural direction, fell the tree in a different direction.

1. Examine the natural fall direction of the tree. For example the tilt and bend of the tree, wind direction, the location of the branches and weight of snow.

2. Examine if there are obstacles, for example other trees, power lines, roads and/or buildings around.

3. Look for signs of damage and rot in the stem.

WARNING: Rot in the stem can mean a risk that the tree falls before you complete the cutting.

1. Make sure the tree has no damaged or dead branches that can break off and hit you during felling.

2. Do not let the tree fall onto a different standing tree. It is dangerous to remove a caught tree and there is a high accident risk. Refer to To free a trapped tree on page 19.

To fell a tree

Husqvarna recommends you to make the directional cuts and then use the safe corner method when you fell a tree. The safe corner method helps you to make a correct felling hinge and control the felling direction.

WARNING: Do not fell trees with a diameter that is more than two times larger than the guide bar length. For this, you must have special training.

The felling hinge

The most important procedure during tree felling is to make the correct felling hinge. With a correct felling hinge, you control the felling direction and make sure that the felling procedure is safe.

The thickness of the felling hinge must be equal and a minimum of 10% of the tree diameter.

WARNING: If the felling hinge is incorrect or too thin, you have no control of the felling direction.

Diagram of concentric circular layers with a vertical bar and directional arrows, no text or symbols present

To make the directional cuts

1. Make the directional cuts 14 of the diameter of the tree. Make a 45^-70^ angle between the top directional cut and bottom directional cut.

a) Make the top directional cut. Align the felling direction mark (1) of the product with the felling direction of the tree (2). Stay behind the product and keep the tree on your left side. Cut with a pull stroke. b) Make the bottom directional cut. Make sure that the end of the bottom directional cut is at the same point as the end of the top directional cut.

1. Make sure that the bottom directional cut is horizontal and at a 90^ angle to the felling direction.

To use the safe corner method

The felling cut must be made slightly above the directional cut.

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.

- Round file diameter.

Simple line drawing of a dropper with a small symbol (no text or labels)

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 and the kickback risk at a minimum.

WARNING: The force of the kickback increases a lot if you do not follow the sharpening instructions.

Note: Refer to To sharpen the saw chain on page 27 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.

Line drawings of three mechanical components: a dropper, a bracket, and a clip (no text or symbols)

Note: Refer to Accessories on page 36 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. See Accessories on page 36 for instructions about how to receive the correct depth gauge setting for your saw chain.

WARNING: The risk of kickback increases if the depth gauge setting is too large!

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 28, 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.
