Bef ore using a new chain saw
Please read this manual carefully.
• Check that the cutting equipment is correctly fitted and
adjusted. See instructions under the heading
Assembly.
• Refuel and start the chain saw. See the instructions
under the headings Fuel Handling and Starting and
Stopping.
• Do not use the chain saw until sufficient chain oil has
reached the chain. See instructions under the heading
Cutting equipment.
• Long-term exposure to noise can result in permanent
hearing impairment. So always use approved hearing
protection.
ARNING! Under no circumstances may
the design of the machine be modified
!
without the permission of the
manufacturer. Always use genuine
accessories. Non-authorized
modifications and/or accessories can
result in serious personal injury or the
death of the operator or others. Your
warranty may not cover damage or
liability caused by the use of nonauthorized accessories or replacement
parts.
ARNING! A chain saw is a dangerous
tool if used carelessly or incorrectly and
!
can cause serious, even fatal injuries. It
is very important that you read and
understand the contents of this
operator’s manual.
ARNING! The inside of the muffler
contain chemicals that may be
!
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
ARNING! Long term inhalation of the
engine’s exhaust fumes, chain oil mist
!
and dust from sawdust can represent a
health risk.
ARNING! The ignition system of this
machine produces an electromagnetic
!
field during operation. This field may
under some circumstances interfere with
pacemakers. To reduce the risk of
serious or fatal injury, we recommend
persons with pacemakers to consult
their physician and the pacemaker
manufacturer before operating this
machine.
ARNING! Never allow children to use or
be in the vicinity of the machine. As the
machine is equipped with a springloaded stop switch and can be started by
low speed and force on the starter
handle, even small children under some
circumstances can produce the force
necessary to start the machine. This can
mean a risk of serious personal injury.
Therefore remove the spark plug cap
when the machine is not under close
supervision.
Impor tant
IMPOR TANT!
The machine is only designed for cutting wood.
You should only use the saw with the bar and chain
combinations we recommend in the chapter Technical
data.
Never use the machine if you are fatigued, while under
the influence of alcohol or drugs, medication or anything
that could affect your vision, alertness, coordination or
judgement.
Wear personal protective equipment. See instructions
under the heading Personal protective equipment.
Do not modify this product or use it if it appears to have
been modified by others.
Never use a machine that is faulty. Carry out the checks,
maintenance and service instructions described in this

GENERAL SAFETY PRECA UTIONS
!
Always use common sense
It is not possible to cover every conceivable situation you
can face when using a chain saw. Always exercise care and
use your common sense. Avoid all situations which you
consider to be beyond your capability. If you still feel
uncertain about operating procedures after reading these
instructions, you should consult an expert before continuing.
Do not hesitate to contact your dealer or us if you have any
questions about the use of the chain saw. We will willingly be
of service and provide you with advice as well as help you to
use your chain saw both efficiently and safely. Attend a
training course in chain saw usage if possible. Your dealer,
forestry school or your library can provide information about
which training materials and courses are available.
Work is constantly in progress to improve the design and
technology - improvements that increase your safety and
efficiency. Visit your dealer regularly to see whether you
can benefit from new features that have been introduced.
Personal protective equipment
WARNING! Most chain saw accidents
happen when the chain touches the
!
operator. You must use approved
personal protective equipment whenever
you use the machine. Personal protective
equipment cannot eliminate the risk of
injury but it will reduce the degree of
injury if an accident does happen. Ask
your dealer for help in choosing the right
equipment.
• 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
Generally clothes should be close-fitting without
restricting your freedom of movement.
IMPORTANT! Sparks can come from the muffler, the bar
and chain or other sources. Always have fire
extinguishing tools available if you should need them.
Help prevent forest fires.
Machine′′′′s safety equipment
In this section the machine’s safety features and their
function are explained. For inspection and maintenance
see instructions under the heading Checking, maintaining
and servicing chain saw safety equipment. See
instructions under the heading, What is what?, to find
where these parts are located on your machine.
The life span of the machine can be reduced and the risk
of accidents can increase if machine maintenance is not
carried out correctly and if service and/or repairs are not
carried out professionally. If you need further information
please contact your nearest servicing dealer.
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
8 – English
Take care when using your saw and make sure the
kickback zone of the bar never touches any object.
115 11 98-95 Rev.1 2009-01-20
GENERAL SAFETY PRECAUTIONS
• 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.
• The chain brake is released by moving the front hand
guard marked ”PULL BACK TO RESET” back,
towards the front handle.
• 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. Do not leave the chain
saw switched on with the chain brake activated for long
periods. The chain saw can become very hot.
• 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.
115 11 98-95 Rev.1 2009-01-20
• 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
English – 9
GENERAL SAFETY PRECAUTIONS
of the front hand guard, the chain brake can only be
activated by the inertia action.
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 inertia 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.
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.
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.
′s handle unit. The body of the
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.
When fitting the mesh, make sure that the mesh is
inserted in the right position. If necessary, use the
combination spanner to insert or remove the mesh.
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.
Stop switch
Use the stop switch to switch off the engine.
115 11 98-95 Rev.1 2009-01-20
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.

GENERAL SAFETY PRECAUTIONS
General rules
Only use cutting equipment recommended by us!
See instructions under the heading Technical data.
• Keep the chain’s cutting teeth properly
sharpened! Follow our instructions and use the
recommended file gauge. A damaged or badly
sharpened chain increases the risk of accidents.
• 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.
Cutting equipment designed to reduce kickback
WARNING! Faulty cutting equipment or
the wrong combination of bar and saw
chain increases the risk of kickback!
Only use the 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” kickback
reduction and keeping the chain sharp and wellmaintained you can reduce the effects of kickback.
Bar
The smaller the tip radius the lower the chance of
kickback.
Chain
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.
• 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.
12 – English
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
Jonsered. See instructions under the heading Technical
Data for a list of replacement bar and chain combinations
we recommend.
Bar
• Length (inches/cm)
• Number of teeth on bar tip sprocket (T).
• Chain pitch (inches). The spacing between the drive
links of the chain must match the spacing of the teeth
on the bar tip sprocket and drive sprocket.
115 11 98-95 Rev.1 2009-01-20
GENERAL SAFETY PRECAUTIONS
!
• 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.
• A sharp chain eats its way through the wood and
produces long, thick chips or shavings.
• 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.
Chain
• Chain pitch (inches)
• Drive link width (mm/inches)
• Number of drive links.
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.
•
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
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 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.
115 11 98-95 Rev.1 2009-01-20
English – 13
Sharpening cutting teeth
!
GENERAL SAFETY PRECAUTIONS
Adjustment of depth gauge setting
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.
• 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.
• 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.
• 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.
Tensioning the chain
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!
14 – English
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.
