Safety
Keep children and bystanders away while operating
•
a power tool. Distractions can cause you to lose
control.
Electrical safety
• Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools.
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 power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk
of electric shock.
• When operating a power tool 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 power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the
risk of electric shock.
Personal safety
• Stay alert, monitor what you are doing and use
common sense when operating a power tool. Do not
use a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment
1259 - 001 - 11.07.2019
9
of inattention while operating power tools 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 a power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
• Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to
a rotating part of the power tool may result in
personal injury.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves 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.
• The vibration emission during actual use of the
power tool can differ from the declared total value
depending on the ways in which the tool is used.
Operators should identify safety measures to protect
themselves that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it is
running idle in addition to the trigger).
Power tool use and care
• Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it
was designed.
• Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be
repaired.
• Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
• Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained
users.
• Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool´s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
Battery tool 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 power tools 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.
Service
• Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is
maintained.
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 power tool by insulated gripping surface
only, because the saw chain may contact hidden
wiring or its own cord. Saw chain contacting a ”live”
wire may make exposed metal parts of the power
tool ” live” and could give the operator an electric
shock.
• Wear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet
10
1259 - 001 - 11.07.2019
is recommended. Adequate protective clothing will
reduce personal injury by flying debris or accidental
contact with the saw chain.
• Do not operate a chain saw in a tree. Operation of
chain saw while up a tree may result in personal
injury.
• Always keep proper footing and operate the chain
saw only when standing on fixed, secure and level
surface. Slippery or unstable surfaces such as
ladders may cause a loss of balance or control of the
chain saw.
• 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 forward 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 instruction for lubricating, chain tensioning
and changing accessories. Improperly tensioned or
lubricated saw chain may either brake or increase
the chance of kickback.
• Keep handles dry, clean and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
• Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain saw for
cutting plastic, masonry or nonwood building
materials. Use of the chain saw for operations
different than intended could result in a hazardous
situation.
• We strongly recommend that first time users practice
sawing logs on a saw horse or cradle.
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 devises 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 a result of tool 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.
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 bars and chains specified by
the manufacturer. Incorrect replacement bars and
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.

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.(Fig. 31)
WARNING:
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.
.
Do not engage in situations
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.(Fig. 35)
Pull the front hand guard rearward to disengage the
chain brake.(Fig. 36)
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. (Fig.
37)
The front hand guard also decreases the risk to touch
the saw chain if your hand lets go of the front handle.
(Fig. 38)
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.(Fig. 39)
Power trigger lockout
The power trigger lockout prevents accidental operation
of the power trigger. If you put your hand around the
handle and press the power trigger lockout (A), it
releases the power trigger (B). If you release the handle,
the power trigger and the power trigger lockout move
back to their initial positions.(Fig. 40)
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

and
Battery safety
(Fig. 32)
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
brake manually. This movement starts a spring-loaded
mechanism that stops the drive sprocket.(Fig. 33)
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.(Fig. 34)

Chain oil
All Husqvarna chainsaws have an automatic chain
lubrication system. On some models the oil flow is also
adjustable.
Think about the following when you select a chain oil:
(Fig. 51)
• The oil tank lasts approximately three battery
charges. This applies only if you use the correct
chain oil. If the chain oil is too thin, it will not last that
long.
• Chain oil must show good adherence to the saw
chain and also keep its flow quality during warm
summer and cold winter weather.
• Use an oil of the right grade (suitable viscosity
range) to agree with the air temperature. In
temperatures below 0°C (32°F) some oils become
too thick. This can cause the oil pump to overload
and result in damage to the oil pump components.
• Use the recommended cutting equipment. A guide
bar that is too long will use more chain oil.
1259 - 001 - 11.07.2019 15
• Turn to your servicing dealer when you select a
chain oil.
WARNING: Do not use waste oil! Waste oil
is dangerous to you and the environment.
Waste oil also causes damage to the oil
pump, the guide bar and the saw chain.
3. Put the battery in the battery holder. (Fig. 55)
4. Press on the lower part of the battery until you hear
a click sound.
CAUTION: If the battery does not move

WARNING: If the lubrication of the cutting
equipment is not sufficient, it can cause the
saw chain to break. This can cause serious
injury or death to the operator.
CAUTION: If you use vegetable based chain
oil, clean the groove in the guide bar and
saw chain before long-term storage.
Otherwise there is a risk of the saw chain
oxidizing, which causes the saw chain to
become stiff and that the bar tip sprocket
gets clogged.

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
and with large force, which throws the product in the
direction of the operator.(Fig. 60)
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.(Fig. 61)
Kickback only occurs if the kickback zone of the guide
bar touches an object. Do not let the kickback zone
touch an object.(Fig. 60)
A kickback can cause serious
16
1259 - 001 - 11.07.2019
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
Maintenance on page 20
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.

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.
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
on page 19
. (Fig. 75)
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 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.
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.
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. (Fig. 78)
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. (Fig. 79)
To make the felling cut
Note: The felling cut is made on the opposite side of the
tree from the directional cuts.
1. Make the felling cut approximately 3-5 cm/1.5-2 in
above the bottom directional cuts. The cut must be
perfectly horizontal. (Fig. 80)
2. If you have a spiked bumper, put it behind the felling
hinge.
3. Cut on the pull stroke, use full power and forward the
saw chain/guide bar slowly into the tree. Make sure
that the tree does not fall in an unwanted direction.
4. Operate a wedge or breaking bar into the cut when
the cut has accurate depth. (Fig. 81)
5. Complete the felling cut parallel with the directional
cut line. Make sure that the distance between them
is at a minimum of 1/10 of the trunk diameter. The
section of the trunk that is not cut is the felling hinge.
The felling hinge controls the felling direction. (Fig.
82)
WARNING:

The safest procedure is to use one of the following
winches:
• Tractor-mounted (Fig. 87)
• Portable (Fig. 88)
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.
(Fig. 89)
3. Examine which is the safest procedure to release the
tension.
In some situations the only safe procedure is
Note:
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. (Fig. 90)
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. (Fig. 91)
WARNING:
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. (Fig. 92)
7. Continue to cut more into the tree until the tree/
branch bends and the tension is released. (Fig. 93)

Information about the guide bar and saw chain
WARNING:
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
26
, 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.(Fig. 104)
• Number of teeth on bar tip sprocket (T).(Fig. 105)
• 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.(Fig.
106)
• Number of drive links. The number of drive links is
decided by the type of guide bar.(Fig. 107)
Use protective gloves when you

• Bar groove width, in/mm. The groove width in guide
bar must be the same as the chain drive links width.
(Fig. 108)
• Chain oil hole and hole for chain tensioner. The
guide bar must align with product.(Fig. 109)
• Drive link width, mm/in.(Fig. 110)
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).(Fig. 111)
When you sharpen the cutter, think about the following:
• Filing angle.(Fig. 112)
• Cutting angle.(Fig. 113)
• File position.(Fig. 114)
• Round file diameter.(Fig. 115)
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
information about sharpening of the saw chain.
To sharpen the cutters on page 22
for
To sharpen the cutters
1. Use a round file and a file gauge to sharpen the
cutting teeth. (Fig. 116)
Refer to
Note:
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.
(Fig. 117)
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
instructions about how to receive the correct depth
gauge setting for your saw chain.
(Fig. 118)
Accessories on page 26
WARNING: The risk of kickback increases if
the depth gauge setting is too large!
for
To adjust the depth gauge setting
Before you adjust the depth gauge setting or sharpen
the cutters, refer to
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.
(Fig. 119)
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.
2. Put the depth gauge tool on the saw chain.
See the package of the depth gauge tool for
Note:
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 tighten the saw chain
WARNING:
tension can come loose from the guide bar
and cause serious injury or death.
The more you use a saw chain the longer it becomes. It
is important to adjust the saw chain regularly.
Do a check of the saw chain tension each time you refill
with chain oil.
A new saw chain has a running-in period during
Note:
which you must do a check of the tension more
frequently.
1. Fold the knob out until it opens. (Fig. 121)
2. Turn the knob counterclockwise to loosen the drive
sprocket cover. (Fig. 122)

3. Turn the chain tensioner wheel to adjust the tension
on the saw chain. The saw chain must be tight
against the guide bar. (Fig. 123)
Note: Turn the wheel down (+) for more tension and
up (-) for less tension. The saw chain is tightened
correctly when you can turn is easily by hand but is
tight against the guide bar.
4. Turn the knob clockwise to tighten the bar knob.
(Fig. 124)
5. Fold down the knob to lock the tension. (Fig. 125)
To do a check of the saw chain lubrication
Do a check of the saw chain lubrication each third
battery charge.
1. Start the product and let it run at 3/4 power. Hold the
bar approximately 20 cm (8 inches) above a light
coloured surface.
2. If the saw chain lubrication is correct, you will see a
clear line of oil on the surface after 1 minute. (Fig.
126)
3. If the saw chain lubrication is not correct, do the
following checks.
a) Do a check of the oil channel in the guide bar to
make sure that it is not blocked. Clean if
necessary. (Fig. 127)
b) Do a check of the groove in the edge of the guide
bar to make sure that it is clean. Clean if
necessary. (Fig. 128)
c) Make sure that the bar tip sprocket turns freely
and that the lubricating hole in the guide bar tip
sprocket is not blocked. Clean and lubricate if
necessary. (Fig. 129)
4. If the saw chain lubrication does not work after
following the steps above, speak to your servicing
dealer.
To do the maintenance on the chain drive sprocket
The drive system has a drive sprocket.
(Fig. 130)
Do the following maintenance on the chain drive
sprocket:
1. Regularly do a check of the degree of wear on the
drive sprocket. Replace the chain drive sprocket if
there is too much wear.
2. Replace the drive sprocket when you replace the
saw chain.
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. (Fig. 131)
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. (Fig.
132)
To do a check of the guide bar
1. Make sure that the oil channel is not blocked. Clean
if it is necessary. (Fig. 127)
2. Examine if there are burrs on the edges of the guide
bar. Remove the burrs using a file. (Fig. 133)
3. Clean the groove in the guide bar. (Fig. 128)
4. Examine the groove in the guide bar for wear.
Replace the guide bar if it is necessary. (Fig. 134)
5. Examine if the guide bar tip is rough or very worn.
(Fig. 135)
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. (Fig.
129)
7. Turn the guide bar daily to extend its life cycle. (Fig.
