ARNING! 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 fr ont hand guard
our 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.

•
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.
•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.
•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.
If the kickback is less violent or the kickback zone of the
bar is closer to you the chain brake will be activated
manually by the movement of your left hand.

GENERAL SAFETY PRECA UTIONS

No
No
No
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 m y hand always activate the chain
brake during a kickback?
. 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.
Throttle lock
The throttle lock 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 lock
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).
Will m y inetria activated chain brake
always activate during kickback in the
event of a kickback?
. 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 m y chain brake always protect me
from injury in the event of a kickback?
. 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.
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 minimize 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′s handle unit.
English
– 9
GENERAL SAFETY PRECAUTIONS
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.
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.
Stop switch
Use the stop switch to switch off the engine.
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.
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.
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!
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.

!
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 well-maintained you can
reduce the effects of kickback.
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.
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.
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.
•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.

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).
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.
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.
•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.
•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.
