INTR ODUCTION
Dear customer!
Cong ratulations 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 Huskvarna 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 over 300 years of continuous operation, 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. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for
building and construction industry.
Your purchase 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 authorized dealers, ask for the address of your nearest servicing dealer.
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
value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the

WARNING! Never use a machine with
defective safety components. Safety
equipment must be inspected and
maintained. See instructions under the
heading Checking, maintaining and
servicing chain saw safety equipment. If
your machine does not pass all the checks,
take the saw to a servicing dealer for repair.
Chain brake and front hand guard
Your chain saw is equipped with a chain brake that is
designed to stop the chain if you get a kickback. The chain
brake reduces the risk of accidents, but only you can prevent
them.
Approved protective helmet
• Hearing protection
• Protective goggles or a visor
• Gloves with saw protection
• Trousers with saw protection
• Boots with saw protection, steel toe-cap and non-slip
sole
• Always have a first aid kit nearby.
• Fire Extinguisher and Shovel
– English
Take care when using your saw and make sure the kickback
zone of the bar never touches any object.
• The chain brake (A) can either be activated manually (by
your left hand) or automatically by the inertia release
mechanism.
• The brake is applied when the front hand guard (B) is
pushed forwards.
GENERAL SAFETY PRECAUTIONS
• This movement activates a spring-loaded mechanism
that tightens the brake band (C) around the engine drive
system (D) (clutch drum).
• The front hand guard is not designed solely to activate
the chain brake. Another important feature is that it
reduces the risk of your left hand hitting the chain if you
lose grip of the front handle.
• The chain brake must be engaged when the chain saw is
started to prevent the saw chain from rotating.
• Use the chain brake as a ”parking brake” when starting
and when moving over short distances, to reduce the risk
of moving chain accidentally hitting your leg or anyone or
anything close by.
• 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.
• 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.
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.
If the kickback is less violent or the kickback zone of the
bar is closer to you the chain brake is designed to be
activated manually by the movement of your left hand.
• To release the chain brake pull the front hand guard
backwards, towards the front handle.
• 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.
English – 9
GENERAL SAFETY PRECAUTIONS
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.
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.
Will my inetria activated chain brake always
activate during kickback in the event of a
kickback?
No. First your brake must be in working order. Testing the
brake is simple, see instructions under the heading
Checking, maintaining and servicing chain saw safety
equipment. We recommend you do before you begin each
work session. 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 the saw chain.
Third, the chain brake may be activated but 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.
Only you and proper working technique can eliminate
kickback and its danger.
Throttle lockout
The throttle lockout is designed to prevent accidental
operation of the throttle control. When you press the lock (A)
(i.e. when you grasp the handle) it releases the throttle
control (B). When you release the handle the throttle control
and the throttle lockout both move back to their original
positions. This arrangement means that the throttle control is
automatically locked at the idle setting.
Chain catcher
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).
Right hand guard
Apart from protecting your hand if the chain jumps or snaps,
the right hand guard stops branches and twigs from
interfering with your grip on the rear handle.
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to reduce vibration and make operation
easier.
The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine
chain saw, including the cutting equipment, is insulated from
the handles by vibration damping units.

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.
Stop switch
Use the stop switch to switch off the engine.
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
WARNING! The exhaust fumes from the
engine are hot and may contain sparks
!
which can start a fire. Never start the
machine indoors or near combustible
material!
In areas with a hot, dry climate there is a high risk of fires.
These areas are sometimes subject to government rules
requiring among other things the muffler must be equipped
with an approved type of spark arrestor screen.
CAUTION! The muffler gets very hot during and after use.
This also applies during idling. Be aware of the fire hazard,
especially when working near flammable substances and/
or vapours.
WARNING! Never use a saw without a
muffler, or with a damaged muffler. A
damaged muffler may substantially
increase the noise level and the fire hazard.
Keep fire fighting equipment handy. If a
spark arrestor screen is required in your
area, never use the saw without or with a
broken spark arrestor screen.
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
• Reduce the risk of kickback.
• Reduce the risk of the saw chain breaking or jumping off
the bar.
• Obtain optimal cutting performance.
• Extend the life of cutting equipment.
• Avoid increasing vibration levels.

• Number of drive links. The number of drive links is
determined by the length of the bar, the chain pitch and
the number of teeth on the bar tip sprocket.
• Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
• Chain oil hole and hole for chain tensioner. The bar must
be matched to the chain saw design.

GENERAL SAFETY PRECAUTIONS
!
Sharpening your chain and adjusting depth
gauge setting
General information on sharpening cutting teeth
• 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.
• 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 difference
in height between the two (depth gauge setting).
When you sharpen a cutting tooth there are four important
factors to remember.
1 Filing angle
will help you obtain the maximum kickback reduction and
cutting performance from your chain.
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.
Sharpening cutting teeth
To sharpen cutting teeth you will need a round file and a file
gauge. See instructions under the heading Technical data for
information on the size of file and gauge that are
recommended for the chain fitted to your chain saw.
• Check that the chain is correctly tensioned. A slack chain
will move sideways, making it more difficult to sharpen
correctly.
2 Cutting angle
3 File position
4 Round file diameter
It is very difficult to sharpen a chain correctly without the right
equipment. We recommend that you use our file gauge. This
• 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 and file the teeth on the
other side.
• File all the teeth to the same length. When the length of
the cutting teeth is reduced to 0.16 inch (4 mm) the chain
is worn out and should be replaced.
English – 13
GENERAL SAFETY PRECAUTIONS
!
General advice on adjusting depth gauge setting
• 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.
WARNING! The risk of kickback is increased
if the depth gauge setting is too large!
!
Adjustment of depth gauge setting
• 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.
• 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.
Tensioning the chain
WARNING! A slack chain may jump off the
bar and cause serious or even fatal injury.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
Check the chain tension every time you refuel. NOTE! A new
chain has a running-in period during which you should check
the tension more frequently.
Tension the chain as tightly as possible, but not so tight that
you cannot pull it round freely by hand.
• Loosen the bar nuts that hold the clutch cover/chain
brake. Use the combination spanner. Then tighten the
bar nuts by hand as tight as you can.
• Raise the tip of the bar and stretch the chain by
tightening the chain tensioning screw using the
combination spanner. Tighten the chain until it does not
sag from the underside of the bar.
• 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.
14 – English
• Use the combination spanner to tighten the bar nuts
while lifting the tip of the bar at the same time. Check that
you can pull the chain round freely by hand and that it
does not sag from the underside of the bar.
The position of the chain tensioning screw on our chain saws
varies from model to model. See instructions under the
heading What is what? to find out where it is on your model.
GENERAL SAFETY PRECAUTIONS
Lubricating cutting equipment
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
!
which could lead to serious, even fatal
injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain and
also maintain its flow characteristics regardless of whether it
is warm summer or cold winter weather.
As a chain saw manufacturer we have developed an optimal
chain oil which has a vegetable oil base. We recommend the
use of our own oil for both maximum chain life and to
minimise environmental damage. If our own chain oil is not
available, standard chain oil is recommended.
Never use waste oil! Using waste oil can be dangerous to
you and damage the machine and environment.
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.
Checking chain lubrication
• Check the chain lubrication each time you refuel. See
instructions under the heading Lubricating the bar tip
sprocket.
Aim the tip of the bar at a light coloured surface about 20
cm (8 inches) away. After 1 minute running at 3/4 throttle
you should see a distinct line of oil on the light surface.
If the chain lubrication is not working:
• Check that the oil channel in the bar is not obstructed.
Clean if necessary.
• Check that the groove in the edge of the bar is clean.
Clean if necessary.
• The saw chain oil tank and the fuel tank are designed so
that the fuel runs out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburetor as
recommended (a lean mixture may mean that the fuel
lasts longer than the oil) and that you also use the
recommended cutting equipment (a bar that is too long
will use more chain oil).
• 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.
If the chain lubrication system is still not working after
carrying out the above checks and associated measures you
should contact your servicing dealer.
