SAFETY INSTRUCTIONS  
due to kickback, you should also apply the chain brake  
manually if there is a risk of the chain accidentally hitting  
anyone or anything close by.  
Chain brake and front hand guard  
Your chain saw is equipped with a chain brake that is  
designed to stop the chain immediately 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.  
•
•
To release the chain brake pull the front hand guard  
backwards, towards the front handle.  
•
The chain brake (A) can either be activated manually (by  
your left hand) or automatically by the inertia release  
mechanism (a pendulum that swings independently of the  
chain saw. On most of our models the front hand guard  
acts as a counterweight in case of kickback).  
The brake is applied when the front hand guard (B) is  
pushed forwards.  
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.  
This movement activates a spring-loaded mechanism that  
tightens the brake band (C) around the engine drive  
system (D) (clutch drum).  
•
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 will be  
activated by the movement of the counterweight (inertia  
activated) in the kickback direction.  
•
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.  
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.  
You can also use the chain brake as a temporary brake  
when you change position or if you put the chain saw  
down for a short time! Apart from the fact that a chain saw  
with a chain brake greatly reduces the risk of accidents  
•
During felling your left hand grasps the front handle in  
such a way that it cannot activate the chain brake. In this  
position, i.e. when your left hand is in such a position that

SAFETY INSTRUCTIONS  
it cannot affect the movement of the front hand guard, the  
chain brake can only be activated by the inertia of the  
counterweight.  
Vibration damping system  
Your machine is equipped with a vibration damping system  
that is designed to minimise vibration and make operation  
easier.  
When you use a chain saw, vibration is generated by the  
uneven contact between the chain and the wood you are  
cutting.  
•
The inertia activated chain brake is a valuable feature but  
there are certain factors to remember (see point above).  
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. See instructions  
under the heading Cutting equipment.  
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 movement is  
controlled by two independent return springs. This  
arrangement means that the throttle control is automatically  
locked at the idle setting.  
The machine′s vibration damping system reduces the transfer  
of vibration between the engine unit/cutting equipment and  
the machine′s handle unit. The body of the chain saw,  
including the cutting equipment, is insulated from the handles  
by vibration damping units.  
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).  
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.The risk  
increases at low temperatures.  
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.  
Stop switch  
Use the stop switch to switch off the engine.

SAFETY INSTRUCTIONS  
Checking the front hand guard  
Muffler  
The muffler is designed to keep noise levels to a minimum and  
to direct exhaust fumes away from the user.  
Make sure the front hand guard is not damaged and that there  
are no visible defects such as cracks.  
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!  
!
Move the front hand guard forwards and back to make sure it  
moves freely and that it is securely anchored to the clutch  
cover.  
In areas with a hot, dry climate there is a high risk of fires.  
These areas are sometimes controlled by legislation and  
requirements that among other things the muffler must be  
equipped with an approved type of spark arrestor mesh.  
For mufflers it is very important that you follow the instructions  
on checking, maintaining and servicing your machine. See  
instructions under the heading Checking, maintaining and  
servicing the machine’s safety equipment.  
Checking the inertia brake release  
WARNING! The muffler gets very hot in use  
and remains so for a short time afterwards.  
Do not touch the muffler if it is hot!  
!
Hold the chain saw over a stump or other firm object. Let go  
of the front handle so that the bar drops towards the stump as  
the chain saw rotates around the rear handle.

The only way to avoid kickback is to make sure that the  
kickback zone of the bar never touches anything.  
Cutting equipment  
By using cutting equipment with ”built-in” kickback reduction  
and keeping the chain sharp and well-maintained you can  
reduce the effects of kickback.  
This section describes how to choose and maintain your  
cutting equipment in order to:  
Bar

•
•
•
Reduce the risk of kickback.  
The smaller the tip radius the smaller the kickback zone and  
the lower the chance of kickback.  
Reduce the risk of the chain breaking or jumping.  
Obtain maximum cutting performance.  
Extend the life of cutting equipment.  
General rules  
•
Only use cutting equipment recommended by us!  
See the Technical data section.  
Chain  
A chain is made up of a number of links, which are available  
in standard and low-kickback versions.  
•
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 raker clearance! Follow our  
instructions and use the recommended raker gauge.  
Too large a clearance increases the risk of kickback.  
Combining these links in different ways gives different  
degrees of kickback reduction. In terms of kickback reduction  
alone, four different types of link are available.  
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.

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 cuttings will be very small.If the chain is very blunt  
it will not produce any cuttings at all. Wood powder would  
be the only result.  
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 cuttings.  
•
Bar groove width (inches/mm).The groove in the bar must  
match the width of the chain drive links.  
•
The cutting part of the chain is called the cutting link and  
this consists of a cutting tooth (A) and the raker lip (B).The  
cutting depth is determined by the difference in height  
between the two.  
•
Chain oil hole and hole for chain tensioner. The bar must  
be matched to the chain saw design.

SAFETY INSTRUCTIONS  
When you sharpen a cutting tooth there are five important  
factors to remember.  
Sharpening cutting teeth  
1
Filing angle  
To sharpen cutting teeth you will need a round file and a file  
gauge. See the Technical data section for information on the  
size of file and gauge that are recommended for the chain  
fitted to your chain saw.  
2
3
Cutting angle  
File position  
•
•
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 over and file the teeth on the  
other side.  
4
5
Round file diameter  
File depth  
•
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.  
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.  
General advice on setting raker clearance  
•
When you sharpen the cutting teeth you reduce the raker  
clearance (=cutting depth). To maintain optimal cutting  
performance you must file back the raker lip to the  
recommended height.  
See the Technical data section for information about  
sharpening your chain.  
See the Technical data section to find the raker clearance  
for your particular chain.  
WARNING! The following faults will increase  
the risk of kickback considerably:  
!
File angle too large  
Cutting angle too small  
File diameter too small  
•
On a low-kickback cutting link the front edge of the raker  
lip is rounded. It is very important that you maintain this  
radius or bevel when you adjust the raker clearance.  
12 – English  
Download from Www.Somanuals.com. All Manuals Search And Download.  
SAFETY INSTRUCTIONS  
•
We recommend that you use our raker gauge to achieve  
the correct clearance and bevel on the raker lip.  
Tension the chain as tightly as possible, but not so tight that  
you cannot pull it round freely by hand.  
WARNING! The risk of kickback is increased  
if the raker clearance is too large!  
!
Setting the raker clearance  
•
Undo 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.  
•
•
Before setting the raker clearance the cutting teeth should  
be newly sharpened. We recommend that you adjust the  
raker clearance every third time you sharpen the chain.  
NOTE! This recommendation assumes that the length of  
the cutting teeth is not reduced excessively.  
•
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.  
To adjust the raker clearance you will need a flat file and a  
raker gauge.  
•
•
Place the gauge over the raker lip.  
•
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.  
Place the file over the part of the lip that protrudes through  
the gauge and file off the excess.The clearance is correct  
when you no longer feel any resistance as you draw the  
file over the gauge.  
Lubricating cutting equipment  
WARNING! Poor lubrication of cutting  
equipment may cause the chain to snap,  
which could lead to serious, even fatal  
injuries.  
Tensioning the chain  
!
Chain oil  
WARNING! A slack chain may jump off and  
cause serious or even fatal injury.  
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.  
!
The more you use a chain the longer it becomes. It is  
therefore important to adjust the chain regularly to take up the  
slack.  
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.  
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.  
In areas where oil specifically for lubrication of saw chains is  
unavailable, ordinary EP 90 transmission oil may be used.  
The position of the chain tensioning screw on our chain saws  
varies from model to model. See the What is what? section to  
find out where it is on your model.  
Never use waste oil! This is dangerous for yourself, the  
machine and the environment.

SAFETY INSTRUCTIONS  
•
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.  
Filling with chain oil  
•
All our chain saws have an automatic chain lubrication  
system. On some models the oil flow is also adjustable.  
•
The sizes of the chain oil tank and fuel tank have been  
chosen so that the engine will run out of fuel before  
running out of oil. This means that you should never run  
with a dry chain.  
If the chain lubrication system is still not working after carrying  
out the above checks and associated measures you should  
contact your service agent.  
Lubricating the bar tip sprocket  
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 carburettor as recommended  
(a weak 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).  
The above conditions also apply to chain saw models with  
an adjustable oil pump.  
Lubricate the bar tip sprocket each time you refuel. Use the  
special grease gun and a good quality bearing grease.  
Checking chain lubrication  
•
Check the chain lubrication each time you refuel.  
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.  
Needle bearing lubrication  
The clutch drum is fitted with one of the following drive  
sprockets:  
A Spur sprocket (the chain sprocket is welded on the drum)  
B Rim sprocket (replaceable)  
If the chain lubrication is not working:  
•
Check that the oil channel in the bar is not obstructed.  
Clean if necessary.  
Both versions have a needle bearing on the drive shaft, which  
has to be greased regularly (once a week). CAUTION! Use  
only high quality bearing grease or engine oil.  
Checking wear on cutting equipment  
•
Check that the groove in the edge of the bar is clean.  
Clean if necessary.  
Check the chain daily for:  
•
•
•
Visible cracks in rivets and links.  
Whether the chain is stiff.  
Whether rivets and links are badly worn.

What is kickback?  
The word kickback is used to describe the sudden reaction  
that causes the chain saw and bar to jump off an object when  
the upper quadrant of the tip of the bar, known as the kickback  
zone, touches an object.  
•
•
Whether the groove in the bar has become badly worn.  
Replace the bar if necessary.  
Whether the tip of the bar is uneven or badly worn. If a  
hollow forms on the underside of the bar tip this is due to  
running with a slack chain.  
Kickback always occurs in the cutting plane of the bar.  
Normally the chain saw and bar are thrown backwards and  
upwards towards the user. However, the chain saw may move  
in a different direction depending on the way it was being used  
when the kickback zone of the bar touched the object.  
•
To prolong the life of the bar you should turn it over daily.

SAFETY INSTRUCTIONS  
Kickback only occurs if the kickback zone of the bar touches  
5
In order to keep control of your saw, always maintain a firm  
an object.  
foothold. Never work on a ladder, in a tree or on any other  
insecure support.  
General rules  
1
If you understand what kickback is and how it happens  
then you can reduce or eliminate the element of surprise.  
By being prepared you reduce the risk.Kickback is usually  
quite mild, but it can sometimes be very sudden and  
violent.  
6
7
Always use a fast cutting speed, i.e. full throttle.  
Take great care when you cut with the top edge of the bar,  
i.e. when cutting from the underside of the object. This is  
known as cutting on the push stroke. The chain tries to  
push the chain saw back towards the user.  
2
Always hold the chain saw firmly with your right hand on  
the rear handle and your left hand on the front handle.  
Wrap your fingers and thumbs around the handles.You  
should use this grip whether you are right-handed or left-  
handed.This grip minimises the effect of kickback and lets  
you keep the chain saw under control.  
Do not let go of the handles!  
Unless the user resists this pushing force there is a risk  
that the chain saw will move so far backwards that only the  
kickback zone of the bar is in contact with the tree, which  
will lead to a kickback.  
3
Most kickback accidents happen during limbing. Make  
sure you are standing firmly and that there is nothing in  
the way that might make you trip or lose your balance.  
Lack of concentration can lead to kickback if the kickback  
zone of the bar accidentally touches a branch, nearby tree  
or some other object.  
Cutting with the bottom edge of the bar, i.e. from the top of  
the object downwards, is known as cutting on the pull  
stroke. In this case the chain saw pulls itself towards the  
tree and the front edge of the chain saw body rests  
naturally on the trunk when cutting. Cutting on the pull  
stroke gives the operator better control over the chain saw  
and the position of the kickback zone.  
4
Never use the chain saw above shoulder height and try  
not to cut with the tip of the bar.Never use the chain saw  
one-handed!  
8
Follow the instructions on sharpening and maintaining  
your bar and chain. When you replace the bar and chain  
use only combinations that are recommended by us. See  
instructions under the headings Cutting equipment and  
Technical data.  
WARNING! The risk of kickback is increased  
if you use the wrong cutting equipment or a  
chain that is not sharpened correctly.The  
wrong combination of bar and chain can  
increase the risk of kickback!

SAFETY INSTRUCTIONS  
Fuel safety  
General working instructions  
WARNING! This section describes basic  
safety rules for using a chain saw.This  
information is never a substitute for  
professional skills and experience. If you get  
into a situation where you feel unsafe, stop  
and seek expert advice. Contact your chain  
saw dealer, service agent or an experienced  
chain saw user. Do not attempt any task that  
you feel unsure of!  
!
WARNING! Fuel and fuel vapour are highly  
flammable.Take care when handling fuel and  
chain oil. Be aware of the risks of fire,  
explosion and those associated with  
inhalation.  
!
•
•
Never refuel the machine while the engine is running.  
Before using a chain saw you must understand the effects of  
kickback and how to avoid them. See instructions under the  
heading How to avoid kickback.  
Make sure there is plenty of ventilation when refuelling or  
mixing fuel (gasoline and 2-stroke oil).  
•
Move the machine at least 3 m from the refuelling point  
before starting it.  
Before using a chain saw you must understand the difference  
between cutting with the top and bottom edges of the bar.See  
instructions under the heading How to avoid kickback.  
Basic safety rules  
•
Look around you:  
-
To ensure that people, animals or other things cannot  
affect your control of the machine.  
-
To make sure that none of the above might come  
within reach of your saw or be injured by falling trees.  
•
Never start the machine:  
1
If you have spilt fuel or chain oil on the machine.Wipe  
off the spillage and allow remaining fuel to evaporate.  
2
If you have spilt fuel on yourself or your clothes,  
change your clothes. Wash any part of your body that  
has come in contact with fuel. Use soap and water.  
3
If the machine is leaking fuel.Check regularly for leaks  
from the fuel cap and fuel lines.  
Follow the instructions above, but do not use a chain saw in a  
situation where you cannot call for help in case of an accident.  
•
Do not use the machine in bad weather, such as dense  
fog, heavy rain, strong wind, intense cold, etc. Working in  
bad weather is tiring and often brings added risks, such as  
icy ground, unpredictable felling direction, etc.  
Transport and storage  
•
Always store the chain saw and fuel so that there is no risk  
of leakages or fumes coming into contact with sparks or  
naked flames from electrical equipment, electric motors,  
relays/switches, boilers and the like.  
•
Take great care when removing small branches and avoid  
cutting bushes (i.e. cutting many small branches at the  
same time). Small branches can be grabbed by the chain  
and thrown back at you, causing serious injury.  
•
•
Always store fuel in an approved container designed for  
that purpose.  
For longer periods of storage or for transport of the chain  
saw, the fuel and chain oil tanks should be emptied. Ask  
where you can dispose of waste fuel and chain oil at your  
local gas station.  
•
•
Ensure the machine is cleaned and that a complete  
service is carried out before long-term storage.  
•
Make sure you can move and stand safely.Check the area  
around you for possible obstacles (roots, rocks, branches,  
ditches, etc.) in case you have to move suddenly. Take  
great care when working on sloping ground.  
The transport guard must always be fitted to the cutting  
attachment when the machine is being transported or in  
storage.

SAFETY INSTRUCTIONS  
•
Take the utmost care when cutting through branches or  
There are five important factors you should  
consider before making a cut:  
logs that are in tension. A log or branch that is in tension  
can suddenly spring back into its natural position before or  
after you cut it. If you stand on the wrong side or start  
cutting in the wrong place it may strike you or your chain  
saw, so that you lose control. Both situations could cause  
serious injury.  
1
Make sure the cutting equipment will not jam in the cut.  
2
Make sure the object you are cutting will not split.  
3
Make sure the chain will not strike the ground or any other  
object during or after cutting.  
•
Before moving your chain saw switch off the engine and  
lock the chain using the chain brake. Carry the chain saw  
with the bar and chain pointing backwards. Fit a guard to  
the bar before transporting the chain saw or carrying it for  
any distance.  
4
5
Is there a risk of kickback?  
Do the conditions and surrounding terrain affect how  
safely you can stand and move about?  
Two factors decide whether the chain will jam or the object  
that you are cutting will split: the first is how the object is  
supported before and after cutting, and the second is whether  
it is in tension.  
•
Never put a chain saw down while the engine is running  
unless you have it in clear view and the chain brake is on.  
Switch the engine off before leaving your chain saw for  
any length of time.  
In most cases you can avoid these problems by cutting in two  
stages;from the top and from the bottom.You need to support  
the object so that it will not trap the chain or split during  
cutting.  
WARNING! If the chain jams in the cut: stop  
the engine! Don’t try to pull the chain saw  
free. If you do you may be injured by the  
chain when the chain saw suddenly breaks  
free. Use a lever to open up the cut and free  
the chain saw.  
Basic cutting technique  
!
General  
•
•
Always use full throttle when cutting!  
Reduce the speed to idle after every cut (running the  
engine for too long at full throttle without any load, i.e.  
without any resistance from the chain during cutting, can  
lead to serious engine damage).  
The following instructions describe how to handle the  
commonest situations you are likely to encounter when using  
a chain saw.  
•
•
Cutting from above = Cutting on the pull stroke.  
Cutting from below = Cutting on the push stroke.  
Cutting  
Cutting on the push stroke increases the risk of kickback. See  
instructions under the heading How to avoid kickback.  
The log is lying on the ground.There is little risk of the chain  
jamming or the object splitting.However there is a risk that the  
chain will touch the ground when you finish the cut.  
Terms  
Cutting = General term for cutting through wood.  
Limbing = Cutting branches off a felled tree.  
Splitting = When the object you are cutting breaks off before  
the cut is complete.

chain touch the ground as you finish the cut. Maintain full  
throttle but be prepared for what might happen.  
Limbing  
When limbing thick branches you should use the same  
approach as for cutting.  
Cut difficult branches piece by piece.  
2
1
If it is possible (can you turn the log?) stop cutting about 2/3  
of the way through the log.  
3
Tree felling technique  
Turn the log and finish the cut from the opposite side.  
WARNING! It takes a lot of experience to fell  
a tree. Inexperienced users of chain saws  
should not fell trees. Do not attempt any task  
that you feel unsure of!  
!
The log is supported at one end. There is a high risk that it  
will split.  
Safe distance  
The safe distance between a tree that is to be felled and  
anyone else working nearby is at least 21/2 tree lengths.  
Make sure that no-one else is in this ”risk zone” before or  
during felling.  
Start by cutting from below (about 1/3 of the way through).  
Felling direction  
The aim is to fell the tree in a position where you can limb and  
cross-cut the log as easily as possible.You want it to fall on  
ground where you can stand and move about safely.The main  
point to avoid is letting the tree fall onto another tree. See  
instructions under the heading Freeing a tree that has fallen  
badly.  
Finish by cutting from above so that the two cuts meet.  
The log is supported at both ends. There is a high risk that  
the chain will jam.  
Once you have decided which way you want the tree to fall  
you must judge which way the tree would fall naturally.  
Start by cutting from above (about 1/3 of the way through).  
Several factors affect this:  
•
•
•
Lean of the tree  
Bend  
Wind direction

SAFETY INSTRUCTIONS  
•
•
Arrangement of branches  
Weight of snow  
Next make the bottom cut so that it finishes exactly at the end  
of the top cut.  
The directional cuts should run 1/4 of the diameter through  
the trunk and the angle between the top cut and bottom cut  
should be 45°.  
You may find you are forced to let the tree fall in its natural  
direction because it is impossible or dangerous to try to make  
it fall in the direction you first intended.  
Another very important factor, which does not affect the felling  
direction but does affect your safety, is to make sure the tree  
has no damaged or dead branches that might break off and  
hit you during felling.  
The line where the two cuts meet is called the directional cut  
line. This line should be perfectly horizontal and at right  
angles (90°) to the chosen felling direction.  
WARNING! During critical felling operations,  
hearing protectors should be lifted  
immediately when sawing is completed so  
that sounds and warning signals can be  
heard.  
!
Felling cut  
The felling cut is made from the opposite side of the tree and  
it must be perfectly horizontal. Stand on the left side of the  
tree and cut on the pull stroke.  
Clearing the trunk and preparing your retreat  
Remove any branches that are in the way.To do this it is best  
to work from the top down and keep the trunk between you  
and the chain saw. Never limb above shoulder height.  
Make the felling cut about 3-5 cm (1.5-2 inches) above the  
bottom directional cut.  
Use full throttle and bring the bar and chain slowly into the  
tree.Make sure the tree does not start to move in the opposite  
direction to your intended felling direction. Drive a wedge or  
breaking bar into the cut as soon as it is deep enough.  
Remove any undergrowth from the base of the tree and check  
the area for obstacles (stones, branches, holes, etc.) so that  
you have a clear path of retreat when the tree starts to fall.  
Your path of retreat should be roughly 135 degrees away from  
the intended felling direction.  
Finish the felling cut parallel with the directional cut line so that  
the distance between them is at least 1/10 of the trunk  
diameter. The uncut section of the trunk is called the felling  
hinge.  
Felling  
Felling is done using three cuts. First you make the directional  
cuts, which consist of the top cut and the bottom cut, then you  
finish with the felling cut. By placing these cuts correctly you  
can control the felling direction very accurately.  
Directional cuts  
To make the directional cuts you begin with the top cut. Stand  
The felling hinge controls the direction that the tree falls in.  
to the right of the tree and cut on the pull stroke.  
English – 21  
Download from Www.Somanuals.com. All Manuals Search And Download.  
SAFETY INSTRUCTIONS  
All control over the felling direction is lost if the felling hinge is  
too narrow or non-existent, or if the directional cuts and felling  
cut are badly placed.  
Keep the trunk between you and the chain saw as you move  
along the trunk.  
Cutting the trunk into logs  
See instructions under the heading Basic cutting technique.  
Freeing a tree that has fallen badly  
When the felling cut and directional cut are complete the tree  
should start to fall by itself or with the aid of a felling wedge or  
breaking bar.  
Freeing a ”trapped tree”  
It is very dangerous to remove a trapped tree and there is high  
accident risk.  
The safest method is to use a winch.  
•
•
Tractor-mounted  
We recommend that you use a bar that is longer than the  
diameter of the tree, so that you can make the felling cut and  
directional cuts with single cutting strokes. See the Technical  
data section to find out which lengths of bar are  
recommended for your saw.  
Portable  
Cutting trees and branches that are in tension  
There are methods for felling trees with a diameter larger than  
the bar length. However these methods involve a much  
greater risk that the kickback zone of the bar will come into  
contact with the tree.  
Preparations:  
Work out which side is in tension and where the point of  
maximum tension is (i.e. where it would break if it was bent  
even more).  
WARNING! Unless you have special training  
we advise you not to fell trees with a  
diameter larger than the bar length of your  
saw!  
Decide which is the safest way to release the tension and  
whether you are able to do it safely. In complicated situations  
the only safe method is to put aside your chain saw and use  
a winch.  
!
Limbing  
General advice:  
Position yourself so that you will be clear of the tree or branch  
when the tension is released.  
WARNING! Most kickback accidents happen  
during limbing! Pay close attention to the  
position of the kickback zone of the bar  
when you are limbing branches that are in  
tension!  
!
Make sure that you can stand and move about safely.Work on  
the left side of the trunk. Work as close as possible to the  
chain saw for maximum control. If possible, let the weight of  
the chain saw rest on the trunk.  
Make one or more cuts at or near the point of maximum  
tension. Make as many cuts of sufficient depth as necessary  
to reduce the tension and make the tree or branch break at  
the point of maximum tension.  
Never cut straight through a tree or branch that is in  
tension!

ASSEMBLY  
Tension the chain by turning the chain tensioning screw  
Fitting the bar and chain  
clockwise using the combination spanner. The chain should  
be tensioned until it does not sag from the underside of the  
bar.  
WARNING! Always wear gloves, when  
working with the chain, in order to protect  
your hands from injury.  
!
Check that the chain brake is in disengaged position by  
moving the front hand guard towards the front handle.  
The chain is correctly tensioned when it does not sag from the  
underside of the bar, but can still be turned easily by hand.  
Hold up the bar tip and tighten the bar nuts with the  
combination spanner.  
Remove the bar nuts and remove the clutch cover (chain  
brake). Take off the transportation ring (A).  
When fitting a new chain, the chain tension has to be checked  
frequently until the chain is run-in. Check the chain tension  
regularly. A correctly tensioned chain ensures good cutting  
performance and long life.  
Fit the bar over the bar bolts. Place the bar in its rearmost  
position. Place the chain over the drive sprocket locate it in  
the groove on the bar. Begin on the top edge of the bar.  
NOTE!  
Note: If clutch cover is difficult to remove, replace bar nuts,  
engage brake and rerelease (an audible click will be heard if  
released properly).  
Make sure that the edges of the cutting links are facing  
forward on the top edge of the bar.  
Fit the clutch cover and locate the chain adjuster pin in the  
hole in the bar. Check that the drive links of the chain fit  
correctly over the drive sprocket and that the chain is correctly  
located in the groove in the bar. Tighten the bar nuts finger  
tight.

FUEL HANDLING  
Mixing  
Fuel  
•
Always mix the gasoline and oil in a clean container  
intended for fuel.  
CAUTION!The machine is equipped with a two-stroke engine  
and must always been run using a mixture of gasoline and  
two-stroke engine oil. It is important to accurately measure  
the amount of oil to be mixed to ensure that the correct  
mixture is obtained.When mixing small amounts of fuel, even  
small inaccuracies can drastically affect the ratio of the  
mixture.  
•
Always start by filling half the amount of the gasoline to be  
used. Then add the entire amount of oil. Mix (shake) the  
fuel mixture. Add the remaining amount of gasoline.  
•
Mix (shake) the fuel mixture thoroughly before filling the  
machine’s fuel tank.  
WARNING! Always ensure there is adequate  
ventilation when handling fuel.  
!
Gasoline  
•
This engine is certified to operate on unleaded  
gasoline.  
•
Use good quality unleaded gasoline.  
•
•
Do not mix more than one month’s supply of fuel at a time.  
If the machine is not used for some time the fuel tank  
should be emptied and cleaned.  
•
This engine is certified to operate on unleaded  
gasoline.  
•
•
The lowest octane recommended is 87. If you run the  
engine on a lower octane than 87 it can result in knocking.  
This gives rise to a high engine temperature, which can  
result in serious engine damage.  
Chain oil  
When working with continuous high revs (e.g. limbing) a  
higher octane is recommended.  
•
The chain lubrication system is automatic and we  
recommend the use of special oil (chain oil) with good  
adhesion characteristics.  
Two-stroke oil  
•
For the best results and performance use JONSERED  
two-stroke oil, which is specially formulated for our two-  
stroke engines. Mixture 1:50 (2%).  
•
•
Never use two-stroke oil intended for water-cooled  
outboard engines, sometimes referred to as outboard oil.  
Never use oil intended for four-stroke engines.

FUEL HANDLING  
Fuelling  
WARNING!Taking the following precautions,  
will lessen the risk of fire:  
!
Do not smoke or place hot objects near fuel.  
Always shut off the engine before refuelling.  
When refuelling, open the fuel cap slowly so  
that any excess pressure is released gently.  
Tighten the fuel cap carefully after refuelling.  
Always move the machine away from the  
refuelling area before starting.  
Clean the area around the fuel cap. Clean the fuel and chain  
oil tanks regularly. The fuel filter must be replaced at least  
once a year. Contamination in the tanks causes malfunction.  
Make sure the fuel is well mixed by shaking the container  
before refuelling.The capacities of the chain oil tank and fuel  
tank are carefully matched.You should therefore always fill  
the chain oil tank and fuel tank at the same time.

WARNING! Note the following before  
starting:  
on the ground by placing your right foot through the rear  
handle. Pull the starter handle with your right hand and pull  
out the starter cord slowly until you feel a resistance (as the  
starter pawls engage) then pull firmly and rapidly.Never wrap  
the starter cord around your hand  
!
Never start a chain saw unless the bar, chain  
and all covers are fitted correctly. Otherwise  
the clutch can come loose and cause  
personal injuries.  
Always move the machine away from the  
refuelling area before starting.  
Place the machine on firm ground. Make  
sure you have a secure footing and that the  
chain cannot touch anything.  
Keep people and animals well away from the  
working area.  
As the chain brake is still activated the engine must return to  
idling speed as soon as possible by disengaging the throttel  
latch in order to avoid unnecessery wear on the clutch  
assembly.  
Cold engine  
Starting: The chain brake should be activated when starting  
the chain saw. Activate the chain brake by pushing the front  
hand guard forwards.  
Push in the choke control as soon as the engine fire and make  
repeated starting attempts. Immediately press and release  
the throttle when the engine starts. That will disengage the  
throttle latch.  
Ignition; choke: Set the choke control in the choke position.  
This should automatically set the stop switch to the start  
position.  
CAUTION! Do not pull the starter cord all the way out and do  
not let go of the starter handle when the cord is fully extended.

MAINTENANCE  
Carburettor  
WARNING! Contact your servicing dealer, if  
the idle speed setting cannot be adjusted so  
that the chain stops. Do not use the chain  
saw until it has been properly adjusted or  
repaired.  
Your Jonsered product has been designed and manufactured  
to specifications that reduce harmful emissions.  
!
After your unit has been run 8-10 tanks of fuel the engine has  
broken in.To ensure that your unit is at peak performance and  
producing the least amount of harmful emissions after break  
in, have your authorized servicing dealer, who has a  
revolution counter at his disposal, to adjust your carburetor for  
optimum operating conditions.  
Fine adjustment  
When the machine has been ”run-in” the carburettor should  
be finely adjusted. The fine adjustment should be carried  
out by a qualified person. First adjust the L-jet, then the  
idling screw T and then the H-jet.  
Function, Basic settings, Fine adjustment  
WARNING! Do not start the chain saw unless  
the bar, chain and clutch cover (chain brake)  
are fitted, otherwise the clutch may come  
loose and cause personal injury.  
Conditions  
!
•
Before any adjustments are made the air filter should be  
clean and the cylinder cover fitted. Adjusting the  
carburettor while a dirty air filter is in use will result in a  
leaner mixture next time the filter is cleaned.This can give  
rise to serious engine damage.  
Function  
•
The carburettor governs the engine’s speed via the  
throttle control. Air and fuel are mixed in the carburettor.  
The air/fuel mixture is adjustable. Correct adjustment is  
essential to get the best performance from the machine.  
•
•
Carefully turn the L and H needle to the mid point.  
Do not attempt to adjust the L and H jets beyond  
either stop as this could cause damage.  
•
Now start the machine according to the starting  
instructions and let it warm up for 10 minutes. CAUTION!  
If the chain rotates while idling the T-screw must be  
turned anti-clockwise until the chain stops.  
•
•
The setting of the carburetor means that the engine is  
adepted to local conditions, for example, the climate,  
altitude, fuel and the type of 2-stroke oil.  
The carburettor has three adjustment controls:  
•
Place the machine on a flat surface so that the bar points  
away from you and so that the bar and chain do not come  
into contact with the surface or other objects.  
-
-
-
L = Low speed jet  
H = High speed jet  
T = Idle adjustment screw  
Low speed jet L  
Turn the low speed jet L clockwise until it stops. If the engine  
accelerates poorly or idles unevenly, turn the low speed jet L  
anticlockwise until good acceleration and idling are achieved.  
H
L
CAUTION! If the chain rotates while idling the T-screw  
must be turned anti-clockwise until the chain stops.  
Final setting of the idling speed T  
Adjust the idle speed with the T-screw. If it is necessary to re-  
adjust, turn theT-screw clockwise while the engine is running,  
until the chain starts to rotate. Then turn counter-clockwise  
until the chain stops. A correctly adjusted idle speed setting  
occors when the engine runs smoothly in every position. It  
should also be good margin to the rpm when the chain starts  
to rotate.  
T
•
•
The L and H-jets are used to adjust the supply of fuel to  
match the rate that air is admitted, which is controlled with  
the throttle. If they are screwed clockwise the air/fuel ratio  
becomes leaner (less fuel) and if they are turned anti-  
clockwise the ratio becomes richer (more fuel). A lean  
mixture gives a higher engine speed and a rich mixture  
gives a lower engine speed.  
WARNING! Contact your servicing dealer, if  
the idle speed setting cannot be adjusted so  
that the chain stops. Do not use the chain  
saw until it has been properly adjusted or  
repaired.  
!
The T-screw regulates the throttle setting at idle speed. If  
the T-screw is turned clockwise this gives a higher idle  
speed; turning it anti-clockwise gives a lower idle speed.  
Basic settings and running in  
High speed jet H  
The carburettor is set to its basic setting when test run at the  
factory. The basic setting is richer than the optimum setting  
and should be maintained for the first hours that the machine  
is in use.The carburettor should then be finely adjusted. Fine  
adjustment should be carried out by a suitably trained person.  
The high speed needle H influence the power of the machine.  
A too lean adjusted high speed (high speed needle H turn too  
much clockwise) gives overrevs and damages the engine. Do  
not allow the engine to run at full speed for more than 10  
seconds. Turn the high speed needle H counter-  
clockwiseuntil the stop. If the engine runs roughly, turn the  
high speed needle slowly the minimum amount clockwise  
until the engine runs smoothly. The high speed needle H is  
correctly set when the saw “4-cycles” a little. If the machine

Wind approx. 3 turns of the starter cord onto the pulley.  
Connect the pulley to the recoil spring so that the end of  
the spring engages in the pulley.Fit the screw in the centre  
of the pulley. Insert the starter cord through the hole in the  
starter housing and the starter handle. Make a secure  
knot in the end of the starter cord.  
H
For optimum setting of the carburetor, contact a qualified  
servicing dealer who has a revolution counter at his  
disposal.  
Correctly adjusted carburettor  
When the carburettor is correctly adjusted the machine  
accelerates without hesitation and the machine 4-cycles a  
little at max speed. It is also important that the chain does not  
rotate at idle. If the L-jet is set too lean it may cause starting  
difficulties and poor acceleration.If the H-jet is set too lean the  
machine will have less power, poor acceleration and could  
suffer damage to the engine. If the L and H-jets are set too  
rich it will lead to acceleration problems or too low a working  
speed.  
Tensioning the recoil spring  
•
Hook the starter cord in the notch in the pulley and turn the  
starter pulley about 2 turns clockwise.  
Starter  
WARNING! When the recoil spring is wound  
up in the starter housing it is under tension  
and can, if handled carelessly, pop out and  
cause personal injury. Always be careful  
when changing the recoil spring or the  
starter cord. Always wear protective  
goggles.  
!
CAUTION! Check that the pulley can be turned at least a  
further 1/2 turn when the starter cord is pulled all the way out.  
Changing a broken recoil spring  
Changing a broken or worn starter cord  
•
•
Lift off the pulley. See instructions under heading  
Changing a broken or worn starter cord.  
Remove the recoil spring from inside the pulley by tapping  
the pulley lightly with its inside face downwards against a  
work bench or the like. If the spring pops out during fitting,  
wind it up again, working from the outside in towards  
centre.  
•
Loosen the screws that hold the starter against the  
crankcase and remove the starter.  
•
Lubricate the recoil spring with light oil. Fit the pulley and  
tension the recoil spring.  
•
Pull out the cord approx. 30 cm and hook it into the notch  
in the rim of the pulley. Release the recoil spring by letting  
the pulley rotate slowly backwards.

MAINTENANCE  
Fitting the starter  
Spark plug  
•
To fit the starter, first pull out the starter cord and place the  
starter in position against the crankcase. Then slowly  
release the starter cord so that the pulley engages with  
the pawls.  
The spark plug condition is influenced by:  
•
Fit and tighten the screws that hold the starter.  
•
•
•
Incorrect carburettor adjustment.  
Wrong fuel mixture (too much oil).  
A dirty air filter.  
These factors cause deposits on the spark plug electrodes,  
which may result in operating problems and starting  
difficulties.  
•
If the machine is low on power, difficult to start or runs  
poorly at idle speed: always check the spark plug first  
before taking any further action. If the spark plug is dirty,  
clean it and check that the electrode gap is 0.5 mm  
(0,020").The spark plug should be replaced after about a  
month in operation or earlier if necessary.  
Air filter  
The air filter must be regularly cleaned to remove dust and dirt  
in order to avoid:  
•
•
•
•
•
Carburettor malfunctions  
Starting problems  
Loss of engine power  
CAUTION! Always use the recommended spark plug type!  
Use of the wrong spark plug can damage the piston/cylinder.  
Unnecessary wear to engine parts  
Excessive fuel consumption.  
Clean the air filter daily, or more often in demanding  
conditions.  
Muffler  
•
Remove the air filter after taking off the air filter cover.  
When refitting make sure that the air filter seals tightly  
against the filter holder. Clean the filter by brushing or  
shaking it.  
The muffler is designed to reduce the noise level and to direct  
the exhaust gases away from the operator.The exhaust gases  
are hot and can contain sparks, which may cause fire if  
directed against dry and combustible material.  
•
The filter can be cleaned more thoroughly by washing it in  
water and detergent.  
Some mufflers are equipped with a special spark arrestor  
mesh. If your machine has this type of muffler, you should  
clean the mesh at least once a week.This is best done with a  
wire brush.  
An air filter that has been in use for a long time cannot be  
cleaned completely.The filter must therefore be replaced with  
a new one at regular intervals. A damaged air filter must  
always be replaced.  
CAUTION! The mesh must be replaced if it is damaged. If the  
mesh is blocked the machine will overheat and this will cause  
damage to the cylinder and piston. Never use a machine with  
a muffler that is in poor condition.  
A JONSERED chain saw can be equipped with different types  
of air filter according to working conditions, weather, season,  
etc. Contact your dealer for advice.  
A muffler fitted with a catalytic converter greatly reduces the  
concentration of hydrocarbons (HC), oxides of nitrogen (NO)  
and aldehydes emitted with exhaust gases. However, it does  
not cut down carbon monoxide (CO), which you cannot smell!  
Consequently, never work in an enclosed or badly ventilated  
area.Good air circulation should always prevail when working  
in snowy hollows, ravines or in confined conditions.

The oil pump is adjustable. Adjustments are made by turning  
the screw using a screwdriver or combination spanner. The  
machine is supplied from the factory with the screw set to  
position 2.Turning the screw clockwise will reduce the oil flow  
and turning the screw anti-clockwise will increase the oil flow.  
Clean the cooling system with a brush once a week, more  
often in demanding conditions. A dirty or blocked cooling  
system results in the machine overheating which causes  
damage to the piston and cylinder.

Check that nuts and screws are tight.  
Test the stop switch to be sure it shuts off the engine.  
10 Check the cooling system on chain saws with catalytic  
converters.  
These reduce the flow of cooling air and prevent large  
amounts of snow from being sucked into the carburettor  
space. CAUTION! When the winter plug is fitted the winter  
flap must be open!  
IMPORTANT! If the special winterising kit has been fitted or  
any measures have been taken to increase the temperature  
these changes must be reversed before the machine is  
used in normal temperature conditions. Otherwise there is  
a risk of overheating, resulting in severe damage to the  
engine.  
IMPORTANT! Any maintenance other than that described in  
this manual must be carried out by your servicing dealer

TECHNICAL DATA  
Recommended original and replacement bar and chain combinations  
Following is a list of recommended cutting equipment for the Jonsered chain saw models 2141, 2145 and 2150.The combinations  
of power head, bar and chain have been investigated in accordance with the kickback and vibration requirements of ANSI B 175.1–  
2000.  
The guide bar nose radius is determined by either the maximum number of teeth in the nose sprocket or the corresponding  
maximum nose radius of a solid bar.  
The following list is the chain saw manufacturers recommendations. There may be other combinations available, which will also  
achieve kickback reduction.  
As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius than in our list. For guide  
bars of the same length, all sprocket-nose guide bars of the same pitch and having the same number of sprocket teeth may be  
considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar  
may be considered to have equivalent or less kickback energy than the sprocket-nose bar.  
Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B 175.1 safety requirements  
for gasoline powered chain saws when tested on the representative sample of chain saws below 3.8 cu. in. specified in ANSI 175.1.  
We recommend that you as a replacement use the listed chains or "Low kickback saw chains" which are available at your dealer.
