specially important parts of the manual.
WARNING: Used if there is a risk of
injury or death for the operator or bystanders
if the instructions in the manual are not
obeyed.
CAUTION: Used if there is a risk of
damage to the product, other materials or
the adjacent area if the instructions in the

General machine safety warnings
WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this machine. Failure to follow
all instructions listed below may result in
electric shock, fire and/or serious injury.
• Save all warnings and instructions for future
reference. The term "machine" in the warnings refers
to your mains-operated (corded) machine or battery-
operated (cordless) machine.
Work area safety
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate machines in explosive atmospheres,
such as in the presence of flammable liquids, gases
or dust.Machines create sparks which may ignite the
dust or fumes.
• Keep children and bystanders away while operating
a machine. Distractions can cause you to lose
control.
Electrical safety
• Machine plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs
with earthed (grounded) machines. Unmodified plugs
and matching outlets will reduce risk of electric
shock.
• Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
•
Do not expose machines to rain or wet conditions.
Water entering a machine will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the machine. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk
of electric shock.
• When operating a machine outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
• If operating a machine in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of a RCD reduces the risk of
electric shock.
Personal safety
• Stay alert, watch what you are doing and use
common sense when operating a machine. Do not
use a machine while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating machines may result in
serious personal injury.
• Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce
personal injuries.
• Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the machine. Carrying machines with your finger
on the switch or energising machines that have the
switch on invites accidents.
• Remove any adjusting key or wrench before turning
the machine on. A wrench or a key left attached to
a rotating part of the machine may result in personal
injury.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the
machine in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair
can be caught in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of
machines allow you to become complacent and
ignore machine safety principles. A careless action
can cause severe injury within a fraction of a second.

Machine use and care
• Do not force the machine. Use the correct machine
for your application. The correct machine will do the
job better and safer at the rate for which it was
designed.
• Do not use the machine if the switch does not turn
it on and off. Any machine that cannot be controlled
with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or
remove the battery pack, if detachable, from the
machine before making any adjustments, changing
accessories, or storing machines. Such preventive
safety measures reduce the risk of starting the
machine accidentally.
• Store idle machines out of the reach of children and
do not allow persons unfamiliar with the machines
or these instructions to operate the machines.
Machines are dangerous in the hands of untrained
users.
• Maintain machines and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may affect
the machines´s operation. If damaged, have the
machine repaired before use. Many accidents are
caused by poorly maintained machines.
• Keep cutting tools sharp and clean. Properly
maintained cutting machines with sharp cutting
edges are less likely to bind and are easier to
control.
• Use the machine, accessories and bits etc. in
accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the machine for operations
different from those intended could result in a
hazardous situation.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the machine in unexpected situations.
Battery machine use and care
• Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another battery pack.
• Use machines only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
• When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause
burns or a fire.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritations or burns.
• Do not use a battery pack or machine that
is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behaviour
resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or machine to
fire or excessive temperature. Exposure to fire or
temperature above 130 °C / 265 °F may cause
explosion.
• Follow all charging instructions and do not charge
the battery pack or machine outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
Service
• Have your machine serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the machine is
maintained.
• Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.
General chain saw safety warnings
• Keep all parts of the body away from the saw chain
when the chain saw is operating. Before you start
the chain saw, make sure the saw chain is not
contacting anything. A moment of inattention while
operating chain saws may cause entanglement of
you clothing or body with the saw chain.
• Always hold the chain saw with your right hand
on the rear handle and your left hand on the front
handle. Holding the chain saw with a reversed hand
configuration increases the risk of personal injury
and should never be done.
• Hold the chain saw by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring. Saw chains contacting a ”live” wire may make
exposed metal parts of the chain saw ”live” and
could give the operator an electric shock.
• Wear eye protection. Further protective equipment
for hearing, head, hands, legs and feet is
recommended. Adequate protective equipment will
reduce personal injury from flying debris or
accidental contact with the saw chain.
• Do not operate a chain saw in a tree, on a ladder,
from a rooftop, or any unstable support. Operation
of a chain saw in this manner could result in serious
personal injury.
1
• Always keep proper footing and operate the chain
saw only when standing on fixed, secure and level
surface. Slippery or unstable surfaces may cause a
loss of balance or control of the chain saw.
1
If you are trained in special cutting and working techniques, and properly secured (lift bucket, ropes, safety
harness), deviations from this safety regulation can be made.
6 2022 - 008 - 23.04.2025
• When cutting a limb that is under tension, be alert
for spring back. When the tension in the wood fibres
is released, the spring loaded limb may strike the
operator and/or throw the chain saw out of control.
• Use extreme caution when cutting brush and
saplings. The slender material may catch the saw
chain and be whipped toward you or pull you off
balance.
• Carry the chain saw by the front handle with the
chain saw switched off and away from your body.
When transporting or storing the chain saw, always
fit the guide bar cover. Proper handling of the chain
saw will reduce the likelihood of accidental contact
with the moving saw chain.
• Follow instructions for lubricating, chain tensioning
and changing the bar and chain. Improperly
tensioned or lubricated chain may either brake or
increase the chance for kickback.
• Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain saw for
cutting metal, plastic, masonry or non-wood building
materials. Use of the chain saw for operations
different than intended could result in a hazardous
situation.
• Do not attempt to fell a tree until you have
an understanding of the risks and how to avoid
them. Serious injury could occur to the operator or
bystanders while felling a tree.
• Follow all instructions when clearing jammed
material, storing or servicing the chain saw. Make
sure the switch is off and the battery pack is
removed. Unexpected actuation of the chain saw
while clearing jammed material or servicing may
result in serious personal injury.
• Do not operate a chain saw in a tree unless you
have been specifically trained to do so. Operation of
a chain saw in a tree without proper training could
increase the risk of serious personal injury.
Causes and operator prevention of kickback
Kickback may occur when the nose or tip of the guide
bar touches an object, or when the wood closes in and
pinches the saw chain in the cut. Tip contact in some
cases may cause a sudden reverse reaction, kicking the
guide bar up and back towards the operator. Pinching
the saw chain along the top of the guide bar may push
the guide bar rapidly back towards the operator. Either
of these reactions may cause you to lose control of the
saw which could result in serious personal injury. Do
not rely exclusively upon the safety devices built into
your saw. As a chain saw user, you should take several
steps to keep your cutting jobs free from accident or
injury. Kickback is the result of chain saw misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. Kickback forces can be
controlled by the operator, if proper precautions are
taken. Do not let go of the chain saw.
• Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact
and enables better control of the chain saw in
unexpected situations.
• Only use replacement guide bars and saw chains
specified by the manufacturer. Incorrect replacement
guide bars and saw chains may cause chain
breakage and/or kickback.
• Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.

minutes.
Chain brake and front hand guard
Your product has a chain brake that stops the saw chain
if you get a kickback. The chain brake decreases the
risk of accidents but only you can prevent them.
WARNING: Do not engage in situations
where there is a risk of kickback. Be careful
when you use your product and make sure
that the kickback zone of the guide bar does
not touch an object.
The chain brake engages (A) manually by your left hand
or automatically by the inertia release mechanism. Push
the front hand guard (B) forward to engage the chain
12
2022 - 008 - 23.04.2025
brake manually. This movement starts a spring-loaded
mechanism that stops the drive sprocket.
B
A
How the chain brake is engaged is in relation to the
force of the kickback and position of the product. If
you get an intense kickback while the kickback zone is
farthest away from you, the chain brake engages by the
inertia release. If the kickback is small or the kickback
zone is nearer you, the chain brake engages manually
by your left hand.
Use the chain brake as a parking brake when you
start the product and when you move short distances.
This decreases the risk that you or a person near you
touches the saw chain.
Pull the front hand guard rearward to disengage the
chain brake.
A kickback can be very sudden and intense. Most
kickbacks are small and do not always engage the chain
brake. If a kickback occurs when you use the product,
hold tightly around the handles and do not let go.
The front hand guard also decreases the risk to touch
the saw chain if your hand lets go of the front handle.
In the felling position you cannot engage the chain brake
manually. The chain brake can in this position only be
engaged by the inertia release mechanism.
Power trigger lockout
The power trigger lockout prevents accidental operation
of the power trigger. If you push the power trigger
lockout forward (A) and then push the power trigger
lockout against the handle (B), it releases the power
2022 - 008 - 23.04.2025
13
trigger (C). If you release the handle, the power trigger
and the power trigger lockout move back to their initial
positions.
C
A
B
Chain catcher
The chain catcher catches the saw chain if it breaks or
comes loose. If you have the correct chain tension, the
risk decreases. You also decrease the risk if you do the
correct maintenance on the guide bar and saw chain.
See
Assembly on page 16
and
Maintenance on page
28
for instructions.
Right hand guard
The right hand guard works as a protection for your
hand if the saw chain breaks or comes loose. It also
prevents interference from branches and twigs when
you use the product.

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.
Kickback only occurs if the kickback zone of the guide
bar touches an object. Do not let the kickback zone
touch an object.
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.
2022 - 008 - 23.04.2025
19
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.
• Will the inertia release mechanism always engage
the chain brake during kickback?
No. First, the chain brake must operate correctly.
Refer to
Maintenance and checks of the safety
devices on the product on page 30
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.

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:
If it is dangerous or not
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.
24
2022 - 008 - 23.04.2025
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
To free a trapped tree
on page 27
.
WARNING: During critical felling
operations, lift your hearing protection
immediately when the sawing is
complete. It is important that you hear
sounds and warning signals.
To clear the trunk and prepare your path of
retreat
Cut off all branches from your shoulder height and
down.
1. Cut on the pull stroke from the top down. Make sure
that the tree is between you and the product.
2. Remove undergrowth from the work area around the
tree. Remove all cut off material from the work area.
3. Do a check of the area for obstacles such as stones,
branches and holes. You must have a clear path
of retreat when the tree starts to fall. Your path of
retreat must be approximately 135 degrees away
from the felling direction.

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.
To make the directional cuts
1. Make the directional cuts. Run the directional cuts
1/4 of the diameter of the tree. Make a 45° angle
between the top cut and bottom cut.
a) Make the top cut first. Align the felling direction
mark (A) of the product with the felling direction
of the tree (B). Stay behind the product and keep
the tree on your right side. Cut with a pull stroke.
2022 - 008 - 23.04.2025
25
b) Make the bottom cut. Make sure that the end of
the bottom cut is at the same point as the end of
the top cut.
A
B
2. Make sure that the directional cut line is perfectly
horizontal and at right angles (90°) to the felling
direction. The directional cut line goes through the
point where the two directional cuts touch.
45º-70º
To use the safe corner method
The felling cut must be made slightly above the
directional cut.
WARNING:
Be careful when you cut
with the guide bar tip. Start to cut with the
lower section of the guide bar tip as you
make a bore cut into the trunk.
1. If the usable cutting length is longer than the tree
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.
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,
to complete the safe corner.
3. Put a wedge in the kerf straight from behind.
26
2022 - 008 - 23.04.2025
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.
The safest procedure is to use one of the following
winches:
• Tractor-mounted
• Portable
To cut trees and branches that are in tension
1. Figure out which side of the tree or branch that is in
tension.
2. Figure out where the point of maximum tension is.
3. Examine which is the safest procedure to release the
tension.
Note: In some situations the only safe procedure
is to use a winch and not your product.
4. Keep a position where the tree or branch can not hit
you when the tension is released.
5. Make one or more cuts of sufficient depth necessary
to decrease the tension. Cut at or near the point of
maximum tension. Make the tree or branch break at
the point of maximum tension.
WARNING: Do not cut straight
through a tree or branch that is in
tension.
WARNING: Be very careful when
you cut a tree that is in tension. There is
a risk that the tree moves quickly before
or after you cut it. Serious injury can
occur if you are in an incorrect position
or if you cut incorrectly.
6. If you must cut across tree/branch, make 2 to 3 cuts,
1 in. apart and with a depth of 2 in.
2022 - 008 - 23.04.2025
27
7. Continue to cut more into the tree until the tree/
branch bends and the tension is released.
8. Cut the tree/branch from the opposite side of the
bend, after the tension is released.

To sharpen the saw chain
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 41
, for a list of replacement bar and chain
combinations that we recommend.
• 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 =
D
D
2
• 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 and it stresses the engine
32
2022 - 008 - 23.04.2025
unnecessarily. With a blunt saw chain you risk to
shorten the lifetime of the chainsaw. If the saw chain
is very blunt, there will be no wood chips but only fine
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.
• Cutting angle.
• File position.
• Round file diameter.
It is not easy to sharpen a saw chain correctly without
the correct equipment. Use a Husqvarna recommended
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 32
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.
Note: Refer to
Accessories on page 41
for information about which file and gauge that
Husqvarna recommends for your saw chain.
2. Apply the file gauge correctly on to the cutter. Refer
to the instruction supplied with the file gauge.
3. Move the file from the inner side of the cutting teeth
and out. Decrease the pressure on the pull stroke.
4. Remove material from one side of all the cutting
teeth.
5. Turn the product around and remove material on the
other side.
6. 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 41
2022 - 008 - 23.04.2025
33
for instructions about how to receive the correct depth
gauge setting for your saw chain.
A
B
C
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
To sharpen the cutters on page
33
, 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.
1. Use a flat file and a depth gauge tool to adjust
the depth gauge setting. Only use a Husqvarna
recommended depth gauge tool to get the correct
depth gauge setting and bevel for the depth gauge.
2. Put the depth gauge tool on the saw chain.
Note:
See the package of the depth gauge tool for
more information about how to use the tool.
3. Use the flat file to remove the part of the depth
gauge that extends through the depth gauge tool.
To adjust the tension of the saw chain
(with bar bolt)
WARNING:
A saw chain with an
incorrect tension can come loose from the
guide bar and cause serious injury or death.
A saw chain becomes longer when you use it. Adjust the
saw chain regularly.
1. Loosen the bar nut that holds the drive sprocket
cover. Use the combination wrench.
2. Lift the front of the guide bar and turn the chain
tensioning screw. Use the combination wrench.
3. Tighten the saw chain until it is tight against the
