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 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 la wn 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
ity. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for
ior

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 activ ate 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

Will my inetria activated chain brake al ways 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 br ake is too sensitiv e
it would activate all the time which would be a nuisance.
Will my chain brake alwa ys 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 loc k (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. Replace it if necessary with an aluminium chain
catcher (is available as spare part). 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.

equipment and the machine

experience symptoms of overexposure to
vibration. Such symptoms include
numbness, loss of feeling, tingling,

normally appear in the fingers, hands or
wrists. These symptoms may be increased
in cold temperatures.

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!
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

bar/saw chain combinations we
recommend, and follow the filing
instructions. See instructions under the
heading Technical data.
The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything.
By using cutting equipment with ”built-in” kickbac k reduction
and keeping the chain sharp and well-maintained you can
reduce the effects of kickback.

The smaller the tip radius the lower the chance of kickback.

A chain is made up of a number of links, which are availab le

IMPORTANT! No saw chain design eliminates the danger
of kickback.
WARNING! Any contact with a rotating saw
chain can cause extremely serious injuries.
!
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.

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 ex ert 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, thic
k chips or sha
vings.
12 – English
GENERAL SAFETY PRECAUTIONS
!
• 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).

WARNING! Departure from the sharpening

risk of kickback.
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!
English – 13
GENERAL SAFETY PRECAUTIONS
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 y
the correct depth gauge setting and bevel for the depth
gauge.
• Place the depth gauge tool over the chain. Detailed
mation regarding the use of the depth gauge tool,
infor
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.
