INTRODUCTION
Dear Customer,
Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689,
when the Swedish King Karl XI ordered the construction of a factory on the banks of the Husqvarna River, for production
of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-
powered plant. During the more than 300 years in existence, the Husqvarna factory has produced a lot of different
products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the first
motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working
today.
Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our
highest priority. The business concept is to develop, manufacture and market motor-driven products for forestry and
gardening, as well as for the building and construction industry. Husqvarna′s aim is also to be at the front edge for
ergonomics, usability, security and environmental protection. That is the reason why we have developed many different
features to add to our products within these areas.
We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very
long time to come. The purchase of one of our products gives you access to professional help with repairs and service
whenever this may be necessary. If the retailer who sells your machine is not one of our authorised dealers, ask for the
address of your nearest service workshop.
It is our wish that you will be satisfied with your product and that it will be your companion for a long time. Think of this
operator′s manual as a valuable document. By following its content (usage, service, maintenance, etc), the life span and
the second-hand value of the machine can be extended. If you sell this machine, make sure that the operator′s manual
is passed on to the buyer.
Thank you for using a Husqvarna product.
Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and
appearance of products without prior notice.

GENERAL SAFETY PRECAUTIONS
moment of inattention while operating power tools
may result in serious personal injury.
General power tool safety
warnings
•
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.
WARNING! Read all safety warnings and
all instructions. Failure to follow the
warnings and instructions may result in
electric shock, fire and/or serious injury.
!
•
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 tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
IMPORTANT! Save all warnings and instructions for
future reference. The term ”power tool” in the warnings
refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
•
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.
Work area safety
•
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
•
•
Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
•
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
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.
•
Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control.
•
•
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.
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 the risk of electric shock.
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).
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.
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 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.
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.
•
•
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.
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.
If operating a power tool in a damp location is
unaviodable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
Personal safety
•
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.
•
Stay alert, watch 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

GENERAL SAFETY PRECAUTIONS
•
Maintain power tools. Check for misalignment or
wire may make exposed metal parts of the power tool
” live” and could give the operator an electric shock.
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.
•
•
Do not operate a chain saw in a tree. Operation of
chain saw while up a tree may result in personal injury.
Wear safety glasses and hearing protection.
Further protective equipment for head, hands,
legs and feet is recommended. Adequate protective
clothing will reduce personal injury by flying debris or
accidental contact with the saw chain.
•
•
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.
•
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.
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 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.
•
•
Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
Carry the chain saw by the 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.
When a 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.
•
Follow the instruction for lubricating, chain
tensioning and changing accessories. Improperly
tensioned or lubricated saw chain may either brake or
increase the chance of kickback.
•
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.
•
•
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 intendedcould result in a hazardous
situation.
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.
•
We strongly recommend that first time users practice
sawing logs on a saw horse or cradle.
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.
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
•
•
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”

reduce the risk of moving chain accidentally hitting
your leg or anyone or anything close by.
the bar is closer to you the chain brake will be
activated manually by the movement of your left hand.
•
In the felling position the left hand is in a position that
makes manual activation of the chain brake
impossible. With this type of grip, that is when the left
hand is placed so that it cannot affect the movement
of the front hand guard, the chain brake can only be
activated by the inertia action.
•
To release the chain brake pull the front hand guard
backwards, towards the front handle.
•
Kickback can be very sudden and violent. Most
kickbacks are minor and do not always activate the
chain brake. If this happens you should hold the chain
saw firmly and not let go.
Will my hand always activate the chain
brake during a kickback?
No. It takes a certain force to move the hand guard
forward. If your hand only lightly touches the front guard
or slips over it, the force may not be enough to trigger the
chain brake.You should also maintain a firm grip of the
chain saw handles while working. If you do and
experience a kickback, your hand may never leave the
front handle and will not activate the chain brake, or the
chain brake will only activate after the saw has swung
around a considerable distance. In such instances, the
chain brake might not have enough time to stop the saw
chain before it touches you.
•
The way the chain brake is activated, either manually
or automatically by the inertia release mechanism,
depends on the force of the kickback and the position
of the chain saw in relation to the object that the
kickback zone of the bar strikes.
There are also certain positions in which your hand
cannot reach the front hand guard to activate the chain
brake; for example, when the saw chain is held in felling
position.
If you get a violent kickback while the kickback zone of
the bar is farthest away from you the chain brake is
designed to be activated by the inertia in the kickback
direction.
Will my inertia activated chain brake
always activate during kickback in the
event of a kickback?
No. First your brake must be in working order. Second the
kickback must be strong enough to activate the chain
brake. If the chain brake is too sensitive it would activate
all the time which would be a nuisance.
Will my chain brake always protect me
from injury in the event of a kickback?
No. First, the chain brake must be in working order to
provide the intended protection. Second, it must be
activated during the kickback as described above to stop

Vibrations
if the bar is too close to you the brake might not have
enough time to slow down and stop the chain before the
chain saw hits you.
Cutting hardwoods (most broadleaf trees) creates more
vibration than cutting softwoods (most conifers). Cutting
with cutting equipment that is blunt or faulty (wrong type
or badly sharpened) will increase the vibration level.
Only you and proper working technique can eliminate
kickback and its danger.
Throttle lockout
The power trigger lockout is designed to prevent
accidental operation of the power trigger.When you press
the power trigger lockout (A) (i.e when you grasp the
handle) it releases the power trigger (B). When you
release the handle the power trigger and the power trigger
lockout both move back to their original positions.
WARNING! Overexposure to vibration
can lead to circulatory damage or nerve
!
damage in people who have impaired
circulation. Contact your doctor if you
experience symptoms of overexposure
to vibration. Such symptoms include
numbness, loss of feeling, tingling,
pricking, pain, loss of strength, changes
in skin colour or condition.These
symptoms normally appear in the
fingers, hands or wrists.These

symptoms may be increased in cold
temperatures.
The chain catcher is designed to catch the chain if it snaps
or jumps off. This should not happen if the chain is
properly tensioned (see instructions under the heading
Assembly) and if the bar and chain are properly serviced
and maintained (see instructions under the heading
General working instructions).

GENERAL SAFETY PRECAUTIONS
•
•
Keep the chain’s cutting teeth properly
Saw chain
sharpened! Follow our instructions and use the
recommended file gauge. A damaged or badly
sharpened chain increases the risk of accidents.
A chain is made up of a number of links, which are
available in standard and low-kickback versions.
IMPORTANT! No saw chain design eliminates the
danger of kickback.
WARNING! Any contact with a rotating
saw chain can cause extremely serious
injuries.
Maintain the correct depth gauge setting! Follow
our instructions and use the recommended depth
gauge clearance. Too large a clearance increases
the risk of kickback.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment,
you should replace a worn or damaged bar or chain with
a bar and chain combinations recommended by
Husqvarna. See instructions under the heading Technical
Data for a list of replacement bar and chain combinations
we recommend.
•
•
Keep the chain properly tensioned! If the chain is
slack it is more likely to jump off and lead to increased
wear on the bar, chain and drive sprocket.

Keep cutting equipment well lubricated and
properly maintained! A poorly lubricated chain is
more likely to break and lead to increased wear on the
bar, chain and drive sprocket.

Only use the bar/saw chain combinations
we recommend, and follow the filing
instructions. See instructions under the

The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything.
•
Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
By using cutting equipment with ”built-in” kickback
reduction and keeping the chain sharp and well-
maintained you can reduce the effects of kickback.

Sharpening your chain and adjusting
depth gauge setting
General information on sharpening cutting teeth
It is very difficult to sharpen a chain correctly without the
right equipment. We recommend that you use our file
gauge. This will help you obtain the maximum kickback
reduction and cutting performance from your chain.
•
Never use a blunt chain. When the chain is blunt you
have to exert more pressure to force the bar through
the wood and the chips will be very small. If the chain
is very blunt it will produce wood powder and no chips
or shavings.
•
A sharp chain eats its way through the wood and
produces long, thick chips or shavings.
See instructions under the heading Technical data for
information about sharpening your chain.
WARNING! Departure from the
sharpening instructions considerably
increases the risk of kickback.
!
•
The cutting part of the chain is called the cutter and
consists of a cutting tooth (A) and the depth gauge
(B). The cutters cutting depth is determined by the

data for information on the size of file and gauge that are
recommended for the chain fitted to your chain saw.
Adjustment of depth gauge setting
Li-ion
•
•
The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. We recommend
that you adjust the depth gauge setting every third
time you sharpen the cutting teeth. NOTE! This
recommendation assumes that the length of the
cutting teeth is not reduced excessively.
•
•
Check that the chain is correctly tensioned. A slack
chain will move sideways, making it more difficult to
sharpen correctly.
You will need a flat file and a depth gauge tool. We
recommend that you use our depth gauge tool to
acheive the correct depth gauge setting and bevel for
the depth gauge.
Always file cutting teeth from the inside face. Reduce
the pressure on the return stroke. File all the teeth on
one side first, then turn the chain saw over and file the
teeth on the other side.
•
Place the depth gauge tool over the chain. Detailed
information regarding the use of the depth gauge tool,
will be found on the package for the depth gauge tool.
Use the flat file to file off the tip of the depth gauge that
protrudes through the depth gauge tool. The depth
gauge setting is correct when you no longer feel
resistance as you draw the file along the depth gauge
tool.
•
File all the teeth to the same length. When the length
of the cutting teeth is reduced to 4 mm (5/32") the
chain is worn out and should be replaced.
General advice on adjusting depth gauge setting
Tensioning the chain
•
When you sharpen the cutting tooth (A) the depth
gauge setting (C) will decrease. To maintain optimal
cutting performance the depth gauge (B) has to be
filed down to achieve the recommended depth gauge
setting. See instructions under the heading Technical
data to find the correct depth gauge setting for your
particular chain.
Li-ion
WARNING! A slack chain may jump off
and cause serious or even fatal injury.
!
!
WARNING! Always remove the battery
before any assembly, maintenance and/
or checking is done on the machine.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
WARNING! The risk of kickback is
increased if the depth gauge setting is
too large!
!
Check the chain tension every time you refill with saw
chain oil. NOTE! A new chain has a running-in period
during which you should check the tension more
frequently.

•
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
IMPORTANT! When using vegetable based saw chain
oil, dismantle and clean the groove in the bar and saw
chain before long-term storage.Otherwise there is a risk
of the saw chain oil oxidizing, which will result in the saw
chain becoming stiff and the bar tip sprocket jamming.
Filling with chain oil
•
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
•
Check that the groove in the edge of the bar is clean.
Clean if necessary.
•
Check that the bar tip sprocket turns freely and that
the lubricating hole in the tip sprocket is not blocked.
Clean and lubricate if necessary.
•
The saw chain oil tank is designed to last aproximately
three battery charges. However, this safety feature
requires that you use the right sort of chain oil (if the
chain oil is to thin it will last shorter time).
•
•
•
Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
It is important to use oil of the right grade (suitable
viscosity range) to suit the air temperature.
In temperatures below 0°C (32°F) some oils become
too viscous.This can overload the oil pump and result
in damage to the oil pump components.
If the chain lubrication system is still not working after
carrying out the above checks and associated measures
you should contact your service agent.

Do not use the machine in bad weather, such as
dense fog, heavy rain, strong wind, intense cold, etc.
Working in bad weather is tiring and often brings
added risks, such as icy ground, lightning,
unpredictable felling direction, etc.
Take great care when removing small branches and
avoid cutting bushes (i.e.cutting many small branches
at the same time). Small branches can be grabbed by
the chain and thrown back at you, causing serious
injury.
Make sure you can move and stand safely. Check the
area around you for possible obstacles (roots, rocks,
branches, ditches, etc.) in case you have to move
suddenly. Take great care when working on sloping
ground.
Note! Using the machine with SavE activated only
reduces the chain speed not the cutting power of the
machine.
Take great care when cutting a tree that is in tension.
A tree that is in tension may spring back to its normal
position before or after being cut. If you position
yourself incorrectly or make the cut in the wrong place
the tree may hit you or the machine and cause you to

lose control. Both situations can cause serious
personal injury.
Have control over the workpiece. If the pieces you
intend to cut are small and light, they can jam in the
saw chain and be thrown towards you. Even if this
does not need to be a danger, you may be surprised
and lose control of the saw. Never saw stacked logs or
branches without first separating them. Only saw one
log or one piece at a time. Remove the cut pieces to
keep your working area safe.

Before moving your chain saw deactivate it and lock
the saw chain using the chain brake. Carry the chain
saw with the bar and chain pointing backwards. Fit a
guard to the bar before transporting the chain saw or
carrying it for any distance.
When you put the chain saw on the ground, lock the
saw chain using the chain brake and ensure you have
a constant view of the machine. Deactivate the
machine and remove the battery before leaving your
chain saw for any length of time.
WARNING! Sometimes chips get stuck in
the drive system causing the saw chain

to jam. Always deactivate the machine
and remove the battery before any

Never use the chain saw above shoulder height
and try not to cut with the tip of the bar. Never use
the chain saw one-handed!
General rules
1
If you understand what kickback is and how it happens
then you can reduce or eliminate the element of
surprise. By being prepared you reduce the risk.
Kickback is usually quite mild, but it can sometimes be
very sudden and violent.
2
Always hold the chain saw firmly with your right hand
on the rear handle and your left hand on the front
handle. Wrap your fingers and thumbs around the
handles.You should use this grip whether you are
right-handed or left-handed. This grip minimises the
effect of kickback and lets you keep the chain saw
under control. Do not let go of the handles!
5
You must have a steady stance in order to have full
control over the chain saw. Never work standing on a
ladder, in a tree or where you do not have firm ground
to stand on.
3
Most kickback accidents happen during limbing.Make
sure you are standing firmly and that there is nothing
in the way that might make you trip or lose your
balance.
6
7
Always use a fast cutting speed, i.e. full throttle.
Take great care when you cut with the top edge of the
bar, i.e. when cutting from the underside of the object.
This is known as cutting on the push stroke.The chain
tries to push the chain saw back towards the user. If
Lack of concentration can lead to kickback if the
kickback zone of the bar accidentally touches a
branch, nearby tree or some other object.

Terms
Limbing = Cutting branches off a felled tree.
Splitting = When the object you are cutting breaks off
before the cut is complete.
8
Unless the user resists this pushing force there is a
risk that the chain saw will move so far backwards that
only the kickback zone of the bar is in contact with the
tree, which will lead to a kickback.
There are five important factors you should consider
before making a cut:
1
Make sure the cutting equipment will not jam in the
cut.
2
3
Make sure the object you are cutting will not split.
Cutting with the bottom edge of the bar, i.e. from the
top of the object downwards, is known as cutting on
the pull stroke. In this case the chain saw pulls itself
towards the tree and the front edge of the chain saw
body rests naturally on the trunk when cutting. Cutting
on the pull stroke gives the operator better control over
the chain saw and the position of the kickback zone.
Make sure the chain will not strike the ground or any
other object during or after cutting.

Follow the instructions on sharpening and maintaining
your bar and chain. When you replace the bar and
chain use only combinations that are recommended
by us. See instructions under the headings Cutting

Is there a risk of kickback?
Basic cutting technique
WARNING! Never use a chain saw by
holding it with one hand. A chain saw is
not safely controlled with one hand.
Always have a secure, firm grip around
the handles with both hands.
!
Do the conditions and surrounding terrain affect how
safely you can stand and move about?
Two factors decide whether the chain will jam or the object
that you are cutting will split: the first is how the object is
supported before and after cutting, and the second is
whether it is in tension.
General
•
•
Always use full throttle when cutting!
In most cases you can avoid these problems by cutting in
two stages; from the top and from the bottom.You need to
support the object so that it will not trap the chain or split
during cutting.
Let go of the power trigger after every cut (running the
motor for too long at full power without any load, i.e.

WORKING TECHNIQUES
The log is supported at one end. There is a high risk
that it will split.
WARNING! If the saw chain jams in the
cut: deactivate the machine! Do not try to
pull the machine free. If you do you may
be injured by the saw chain when the
machine suddenly brakes free. Use a
lever to open up the cut and free the
machine.
!
Start by cutting from below (about 1/3 of the way through).
Finish by cutting from above so that the two cuts meet.
The following instructions describe how to handle the
commonest situations you are likely to encounter when
using a chain saw.
Cutting
WARNING! Never attempt to cut logs
while they are in a pile or when a couple

!
of logs are lying together. Such
procedures drastically increase the risk
of kickback which can result in a serious
or fatal injury.
If you have a pile of logs, each log you attempt to cut
should be removed from the pile, placed on a saw horse
or runners and cut individually.
Start by cutting from above (about 1/3 of the way through).
Finish by cutting from below so that the two cuts meet.
Remove the cut pieces from the cutting area. By leaving
them in the cutting area, you increase the risk for
inadvertently getting a kickback, as well as increasing the
risk of losing your balance while working.
Tree felling technique
IMPORTANT! It takes a lot of experience to fell a tree.
Inexperienced users of chain saws should not fell trees.
Do not attempt any task that you feel unsure of!
Safe distance
The log is lying on the ground. There is little risk of the
chain jamming or the object splitting. However there is a
risk that the chain will touch the ground when you finish
the cut.
The safe distance between a tree that is to be felled and
anyone else working nearby is at least 2 1/2 tree lengths.
Make sure that no-one else is in this ”risk zone” before or
during felling.
Cut all the way through the log from above. Avoid letting
the chain touch the ground as you finish the cut. Maintain
full throttle but be prepared for what might happen.
Felling direction
The aim is to fell the tree in a position where you can limb
and cross-cut the log as easily as possible.You want it to
fall in a location where you can stand and move about
safely.
If it is possible (can you turn the log?) stop cutting about
2/3 of the way through the log.
Once you have decided which way you want the tree to fall
you must judge which way the tree would fall naturally.
Turn the log and finish the cut from the opposite side.
Several factors affect this:
•
•
Lean of the tree
Bend

Felling
Obstacles within the reach of the tree: for example,
other trees, power lines, roads and buildings.
WARNING! Unless you have special
training we advise you not to fell trees
with a diameter larger than the bar length
of your saw!
•
Look for signs of damage and rot in the stem, this
makes it more probably that the tree will break and
start to fall before you expect it to.
You may find you are forced to let the tree fall in its natural
direction because it is impossible or dangerous to try to
make it fall in the direction you first intended.
Felling is done using three cuts. First you make the
directional cuts, which consist of the top cut and the
bottom cut, then you finish with the felling cut. By placing
these cuts correctly you can control the felling direction
very accurately.
Another very important factor, which does not affect the
felling direction but does affect your safety, is to make sure
the tree has no damaged or dead branches that might
break off and hit you during felling.
Directional cuts
To make the directional cut you begin with the top cut.Aim
using to the saw’s felling direction mark (1) toward a goal
further forward in the terrain, where you would like the tree
to fall (2). Stand on the right-hand side of the tree, behind
the saw, and cut with a pull stroke.
The main point to avoid is letting the tree fall onto another
tree. It is very dangerous to remove a trapped tree and
there is high accident risk. See instructions under the
heading Freeing a tree that has fallen badly.
Next make the bottom cut so that it finishes exactly at the
end of the top cut.
IMPORTANT! During critical felling operations, hearing
protectors should be lifted immediately when sawing is
completed so that sounds and warning signals can be
heard.
Clearing the trunk and preparing your retreat
1
Delimb the stem up to shoulder height. It is safer to work
from the top down and to have the tree between you and
the saw.
2
The directional cuts should run 1/4 of the diameter
through the trunk and the angle between the top cut and
bottom cut should be 45°.
The line where the two cuts meet is called the directional
cut line. This line should be perfectly horizontal and at
right angles (90°) to the chosen felling direction.
Remove any undergrowth from the base of the tree and
check the area for obstacles (stones, branches, holes,
etc.) so that you have a clear path of retreat when the tree
starts to fall.Your path of retreat should be roughly 135
degrees away from the intended felling direction.
Felling cut
The felling cut is made from the opposite side of the tree
and it must be perfectly horizontal. Stand on the left side
of the tree and cut on the pull stroke.

WORKING TECHNIQUES
Make the felling cut about 3-5 cm (1.5-2 inches) above the
bottom directional cut.
When the felling cut and directional cut are complete the
tree should start to fall by itself or with the aid of a felling
wedge or breaking bar.
Set the spike bumper (if one is fitted) just behind the felling
hinge. Use full throttle and advance the chain/bar slowly
into the tree. Make sure the tree does not start to move in
the opposite direction to your intended felling direction.
Drive a wedge or breaking bar into the cut as soon as it is
deep enough.
We recommend that you use a bar that is longer than the
diameter of the tree, so that you can make the felling cut
and directional cuts with single cutting strokes. See
instructions under the heading Technical data section to
find out which lengths of bar are recommended for your
saw.
There are methods for felling trees with a diameter larger
than the bar length. However these methods involve a
much greater risk that the kickback zone of the bar will
come into contact with the tree.
Finish the felling cut parallel with the directional cut line so
that the distance between them is at least 1/10 of the
trunk diameter.The uncut section of the trunk is called the
felling hinge.
The felling hinge controls the direction that the tree falls in.
Freeing a tree that has fallen badly
Freeing a ”trapped tree”
It is very dangerous to remove a trapped tree and there is
high accident risk.
All control over the felling direction is lost if the felling
hinge is too narrow or non-existent, or if the directional
cuts and felling cut are badly placed.
Never try to fell the tree that is trapped.
Never work in the risk zone of the hanging trapped tree.
The safest method is to use a winch.

Cutting trees and branches that are in tension
How to avoid kickback
Preparations:Work out which side is in tension and where
the point of maximum tension is (i.e. where it would break
if it was bent even more).
WARNING! Kickback can happen very
suddenly and violently; kicking the chain
saw, bar and chain back at the user. If
this happens when the chain is moving it
can cause very serious, even fatal
injuries. It is vital you understand what
causes kickback and that you can avoid
it by taking care and using the right
working technique.
!
Decide which is the safest way to release the tension and
whether you are able to do it safely. In complicated
situations the only safe method is to put aside your chain
saw and use a winch.
General advice:
Position yourself so that you will be clear of the tree or
branch when the tension is released.
What is kickback?
The word kickback is used to describe the sudden
reaction that causes the chain saw and bar to jump off an
object when the upper quadrant of the tip of the bar,
known as the kickback zone, touches an object.
Make one or more cuts at or near the point of maximum
tension. Make as many cuts of sufficient depth as
necessary to reduce the tension and make the tree or
branch break at the point of maximum tension.
Never cut straight through a tree or branch that is in
tension!
Kickback always occurs in the cutting plane of the bar.
Normally the chain saw and bar are thrown backwards
and upwards towards the user. However, the chain saw
may move in a different direction depending on the way it
was being used when the kickback zone of the bar
touched the object.
If you must cut across tree/limb, make two to three cuts,
one inch apart, one to two inches deep.
Continue to cut deeper until tree/limb bends and tension
is released.
Cut tree/limb from outside the bend, after tension has
been released.
Kickback only occurs if the kickback zone of the bar
touches an object.

WORKING TECHNIQUES
Limbing
WARNING! A majority of kickback
accidents occur during limbing. Do not
use the kickback zone of the guide bar.
Be extremely cautious and avoid
contacting the log, other limbs or objects
with the nose of the guide bar. Be
extremely cautious of limbs under
tension.They can spring back toward
you and cause loss of control resulting
in injury.
!
Make sure that you can stand and move about safely.
Work on the left side of the trunk. Work as close as
possible to the chain saw for maximum control.If possible,
let the weight of the chain saw rest on the trunk.
Keep the trunk between you and the chain saw as you
move along the trunk.
Cutting the trunk into logs
