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.
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

Kickback information
WARNING:
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
A kickback can cause serious

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.
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.
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 start the product
To prepare to start with a cold engine
WARNING: The chain brake must be
engaged when the product is started to
decrease the risk of injury.
1. Move the front hand guard forward to engage the
chain brake.
2. Push the air purge bulb approximately 6 times or
until fuel starts to fill the bulb. It is not necessary to
fill the air purge bulb fully.
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.

To keep a safe distance
1. Make sure that persons around you keep a safe
distance at a minimum of 2 1/2 tree lengths.
2. Make sure that no person is in the risk zone before
or during felling.
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:
possible to fell the tree in its natural
direction, fell the tree in a different
direction.
2. 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.
3. Examine if there are obstacles, for example other
trees, power lines, roads and/or buildings around.
4. 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.
5. Make sure the tree has no damaged or dead
branches that can break off and hit you during
felling.
If it is dangerous or not
6. 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

tree. Make a 45°-70° angle between the top
directional cut and bottom directional cut.
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.
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.
2. 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.

diameter, do these steps (a-d).
a) Make a bore cut straight into the trunk to
complete the felling hinge width.
b) Cut on the pull stroke until ⅓ of the trunk is left.
c) Pull the guide bar 5-10 cm/2-4 in rearward.
d) Cut through the remaining of the trunk to
complete a safe corner that is 5-10 cm/2-4 in
wide.
2. If the usable cutting length is shorter than the tree
diameter, do these steps (a-d).
a) Make a bore cut straight into the trunk. The bore
cut must extend 3/5 of the tree diameter.
b) Cut on the pull stroke through the remaining
trunk.
3. Put a wedge in the kerf straight from behind.
4. Cut off the corner to make the tree fall.
Note: If the tree does not fall, hit the wedge until it
does.
5. When the tree starts to fall, use the path of retreat to
move away from the tree. Move a minimum of 5
m/15 ft away from the tree.
To free a trapped tree
WARNING: It is very dangerous to remove a
trapped tree and there is a high accident
risk. Keep out of the risk zone and do not try
to fell a trapped tree.
c) Cut straight into the trunk from the other side of
the tree to complete the felling hinge.
d) Cut on the push stroke, until ⅓ of the trunk is left,

• 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).
• 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.
