GENERAL SAFETY PRECAUTIONS

Before 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
Lubricating cutting equipment.
Long-term exposure to noise can result in permanent
hearing impairment. So always use approved hearing
protection.

Important

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
!
WARNING! 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 non-authorized accessories or
replacement parts.
!
WARNING! 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.
!
WARNING! The inside of the muffler contain
chemicals that may be carcinogenic. Avoid
contact with these elements in the event of a
damaged muffler.
!
WARNING! Long term inhalation of the
engine’s exhaust fumes, chain oil mist and
dust from sawdust can represent a health
risk.
IMPORTANT!
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.

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.

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.
Take care when using your saw and make sure the kickback
zone of the bar never touches any object.
!
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.
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.
!
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.
8 – English
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.
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 the chain hitting your left hand 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.
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.
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.
English – 9
GENERAL SAFETY PRECAUTIONS
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.
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 to 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. 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.
10 – English
GENERAL SAFETY PRECAUTIONS

Vibration damping system

Your machine is equipped with a vibration damping system
that is designed to reduce vibration and make operation
easier.
The machines vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machines handle unit. The body of the 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.

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.
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 mesh.

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.
!
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.
!
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!
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.

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.
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.
Cutting equipment designed to reduce
kickback
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 well-maintained 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.
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.
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.
!
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.
IMPORTANT! No saw chain design eliminates the danger of
kickback.
!
WARNING! Any contact with a rotating saw
chain can cause extremely serious injuries.

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
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.
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.
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.
!
WARNING! Departure from the sharpening
instructions considerably increases the risk
of kickback.
English – 13
GENERAL SAFETY PRECAUTIONS
File all the teeth to the same length. When the length of
the cutting teeth is reduced to 4 mm (0.16") the chain is
worn out and should be replaced.
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.
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.
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

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.
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.
!
WARNING! The risk of kickback is increased
if the depth gauge setting is too large!
!
WARNING! A slack chain may jump off the
bar and cause serious or even fatal injury.

GENERAL SAFETY PRECAUTIONS

Lubricating cutting equipment

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.
Filling with chain oil
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also adjustable.
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).
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.
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.
!
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
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.
