Before using a new saw
• Read the instructions carefully.
• Check cutting equipment is correctly fitted and adjusted. See
page 26.
• Refuel and start the saw. Check the carburettor settings.
See pages 27-30.
• Do not use the saw until sufficient chain oil has reached the
chain, see page 14.
IMPORTANT! If the carburettor mixture is too lean it greatly
increases the risk of engine failure.
Poor maintenance of the air filter will cause carbon build-up on
the spark plug and lead to difficult starting.
If the chain is badly adjusted it will cause increased wear or
damage to the bar, drive sprocket and chain.
Under no circumstances should you modify
the original design of the chain saw without
approval from the manufacturer. Always use
genuine spare parts. Unauthorized
modifications or accessories may lead to
serious injury or death.
!
!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 these
instructions.
IMPORTANT INFORMATION

SAFETY INSTRUCTIONS
PERSONAL PROTECTIVE EQUIPMENT
MOST CHAIN SAW ACCIDENTS HAPPEN
WHEN THE CHAIN TOUCHES THE OPERA-
TOR. You must wear approved protective
equipment whenever you use a chain saw.
Personal protective equipment cannot
eliminate the risk of injury but it will reduce
the degree of injury if an accident does
happen. Ask your chain saw dealer for help in
choosing the right equipment.
Long or continuous exposure to high noise
levels may cause permanent hearing
impairment. Always wear approved hearing
protection when operating a chain saw.

English – 5
1 Chain brake and front hand guard
YOUR chain saw is equipped with a chain brake that is desig-
ned 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.
1 The chain brake (A) can
either be activated
manually (by your left
hand) or automatically by
the inertia release
mechanism (a free-
swinging pendulum). 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.
This movement activates
a spring-loaded
mechanism that tightens
the Brake Band (C)
around the engine drive
system (D) (Clutch Drum).
SAFETY INSTRUCTIONS
2 The front hand guard is
notdesigned solely to
activate the chain brake.
Another important safety
feature is that it prevents
the chain from hitting your
left hand if you lose your
grip on the front handle.
3 Always use the chain
brake as a parking brake
when changing position
and when the saw is put
down for a short time. You
should also apply the
chain brake manually if
there is a risk of the chain
accidentally hitting anyone
or anything close by.
4 To release the chain brake
pull the front hand guard
backwards, towards the
front handle.
5 As mentioned in section A,
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.
B

6– English
6 The way the chain brake is triggered, either manually or
automatically, 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).
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.
7 During felling your left
hand grasps the front
handle in such a way that
it cannot activate the front
hand guard. In this
position the chain brake
can only be activated by
the inertia action of the
counterweight.
The inertia activated
chain brake increases
your safety but there are
certain factors to
remember (see point 6
above).
2 Throttle lock
The throttle lock is designed
to prevent accidental opera-
tion of the throttle control.
When you press the lock (A)
(i.e. when you grasp the
handle) it releases the throttle
trigger (B).
When you release the handle
the throttle trigger 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 when you release
the handle.
3 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 section on
”Assembly” ) and if the bar and
chain are properly serviced
and maintained.
(See section on
”General
working instructions”
).

5 Stop switch
Use the stop switch to switch
off the engine.
6 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
forest 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
saw (see the section on
”Inspecting, maintaining and
servicing chain saw safety
equipment”
).
!
4 Vibration damping system
Your chain saw is equipped
with a vibration damping
system that is designed to
minimise vibrations and make
operation easier.
When you use a chain saw
vibrations are generated by
the uneven contact between
the chain and the wood you
are cutting.
Cutting hardwoods (most
broadleaf trees) creates more
vibration than cutting
softwoods (most conifers).
Working with chain that is
blunt or incorrect (wrong type
or incorrectly sharpened, see
page 11-14) will increase the
level of vibration.
The vibration damping system
reduces the vibrations
transmitted from the engine
and chain to the handles of
the chain saw. The body of
the saw, including the cutting
equipment, is insulated from
the handles by vibration
damping units.
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.
These 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.
SAFETY INSTRUCTIONS
!The exhaust fumes from the engine are hot
and may contain sparks which can start a fire.
Never start the saw indoors or near
combustible material!
STOP
!The muffler gets very hot in use and remains
so for a short time afterwards. DO NOT
TOUCH THE MUFFLER IF IT IS HOT!

SAFETY INSTRUCTIONS
3 Checking the brake trigger
Place the chain saw on a
stable surface and then
start it. Make sure that the
chain cannot come into
contact with the ground or
other object.
Grasp the saw firmly,
wrapping your fingers and
thumbs around the
handles.
Apply full throttle and
activate the chain brake
by tilting your wrist
forward onto the front
hand guard. Do not let go
of the front handle.
The chain should stop
immediately.
Inspecting, maintaining and servicing
chain saw safety equipment
SPECIAL TRAINING IS REQUIRED to service
and repair chain saws. This is especially true
of chain saw safety equipment. If your chain
saw fails any of the checks described below
take it to your SERVICE AGENT.
When you buy any of our products we
guarantee the availability of professional
repairs and service. If the retailer who sells
your saw is not a SERVICING DEALER, ask
him for the address of your nearest SERVICE
AGENT.
1 Chain brake and front hand guard
1 Checking brake band wear
Brush off any sawdust,
resin and dirt from the
chain brake and clutch
drum. Dirt and wear can
impair operation of the
brake.
Regularly check that the
brake band is at least 0.6
mm thick at its thinnest
point.
2 Checking the front hand guard
A) Make sure the
FRONT HAND GUARD
is not damaged and
that there are no visible
defects such as
cracks.
B) Move the front hand
guard forwards and
back to make sure it
runs freely and that it is
securely anchored to
the clutch cover.
Warning!
Never start the saw without first activating the
chain brake!

attached to the body of
the saw.
4 Vibration damping system
Regularly check the
vibration damping units
for cracks or deformation
Make sure the vibration
damping units are
securely attached to the
engine unit and handles.
5 Stop switch
Start the engine and
make sure the engine
stops when you move the
stop switch to the stop
setting.
2 Throttle lock
1 Make sure the throttle
control is locked at the
idle setting when you
release the throttle lock.
2 Press the throttle lock and
make sure it returns to its
original position when you
release it.
3 Check that the throttle
control and throttle lock
move freely and that the
return springs work
properly.
SAFETY INSTRUCTIONS
Warning!
Never start the saw without first activating the
chain brake!
!
4 Start the saw and apply
full throttle. Release the
throttle control and check
that the chain stops and
remains stationary. If the
chain rotates when the
throttle is on idle setting
you should check the
carburettor idle
adjustment. See the
section on
”Maintenance” .

6 Muffler
Never use a chain saw
that has a faulty muffler.
Regularly check that the
muffler is securely
attached to the chain saw.
If the muffler is equipped
with a spark arrestor
mesh, this must be
cleaned regularly. A
blocked mesh will cause
the engine to overheat
and may lead to serious
engine damage.
Never use a muffler that
has a defective 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 chain breaking or jumping.
•Obtain maximum cutting performance.
•Extend the life of cutting equipment.
The 5 basic rules
1Only use cutting
equipment
recommended by us!
See the
”Technical data”
section.
2Keep the chain cutting
teeth properly
sharpened! Follow our
instructions and use the
recommended file
gauge. A damaged or
badly sharpened chain
increases the risk of
accidents.
3Maintain the correct
raker clearance! Follow
our instructions and
use the recommended
raker gauge. Too large a
clearance increases the
risk of kickback.
4Keep the chain properly
tesioned! If the chain is
slack it is more likely to
jump off and lead to
increased wear on the
bar, chain and drive
sprocket.
5Keep 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.
SAFETY INSTRUCTIONS
!NEVER USE A CHAIN SAW WITH FAULTY
SAFETY EQUIPMENT. CARRY OUT THE
CHECKS AND MAINTENANCE MEASURES
DESCRIBED IN THIS SECTION. IF YOUR
CHAIN SAW FAILS ANY OF THESE CHECKS
CONTACT YOUR SERVICE AGENT TO GET IT
REPAIRED.

SAFETY INSTRUCTIONS
C Some terms that describe the bar and chain
When the cutting equipment supplied with your saw becomes
worn or damaged you will need to replace it. Use only the type
of bar and chain recommended by us. See the
”Technical data”
section to find out which equipment is recommended for your
saw.
Bar
• LENGTH (inches/cm)
• NUMBER OF TEETH ON
BAR TIP SPROCKET (T).
Small number = small tip
radius = low-kickback
• 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.
• SAW CHAIN OIL HOLE
AND HOLE FOR CHAIN
TENSIONER
The bar must be matched to
the chain saw design.
Saw chain
• SAW CHAIN PITCH
(inches). (Distance between
three drive links, divided by
two).
• DRIVE LINK WIDTH (mm/
inches)
• NUMBER OF DRIVE LINKS
• LEVEL OF KICKBACK
REDUCTION
The level of kickback
reduction offered by a chain
is indicated by its model
number.
See the
”Technical data”
section to find the model
numbers of chains that are
recommended for use with
your saw.
1 Cutting equipment designed to minimise
kickback
Faulty cutting equipment or the wrong
combination of bar and chain increases the
risk of kickback. Use only the bar and chain
combinations recommended in the
”Technical
data”
section.
The only way to avoid kickback is to make sure that the kick-
back zone of the bar never touches anything.
By using cutting equipment with “built-in” kickback protection
and keeping the chain sharp and well-maintained you can
reduce the effects of kickback.
A Bar
The smaller the tip radius the
smaller the kickback zone and
the lower the chance of
kickback.
B Saw chain
A saw chain is made up of a number of links, which are
available in standard and low-kickback versions.
None Standard Low-kickback
CUTTING LINK
DRIVE LINK
SIDE LINK
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.

2 Sharpening your chain and adjusting
raker clearance
The risk of kickback is increased with a badly
sharpened chain!
A 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, just wood powder.
• A sharp chain eats its way
through the wood and
produces long, thick
cuttings.
• 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.
• When you sharpen a cutting tooth there are five important
factors to remember.
FILING ANGLE
CUTTING ANGLE
FILE POSITION
ROUND FILE DIAMETER
FILE DEPTH
See the
”Technical data” section for information about
sharpening your saw chain.
!
It is very difficult to sharpen a
chain correctly without the
right equipment. We
recommend you use a file
gauge. This will help you
obtain the maximum kickback
reduction and cutting
performance from your chain.
The following faults will increase the risk of
kickback considerably.
• FILE ANGLE TOO
LARGE
• CUTTING ANGLE
TOO SMALL
• FILE DIAMETER
TOO SMALL
B Sharpening cutting teeth
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 your saw
chain.
1 Check that the chain is
correctly tensioned. A
slack chain is difficult to
sharpen correctly.
2 Always file cutting teeth
from the inside face,
reducing the pressure on
the return stroke.
File all the teeth on one
side first, then turn the
saw over and file the
teeth on the other side.
3 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.
B
A
min 4 mm
(0,16")

English – 13
!
C General advice on setting raker clearance
• When you sharpen the
cutting teeth you reduce the
RAKER CLEARANCE
(cutting depth). To maintain
cutting performance you
must file back the raker
teeth to the recommended
height.
See the
”Technical data”
section to find the raker
clearance for your saw
chain.
• 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.
• We recommend the use of a
raker gauge to achieve the
correct clearance and bevel
on the raker lip.
The risk of kickback is increased if the raker
clearance is too large!
SAFETY INSTRUCTIONS
D Setting the raker clearance
• 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.
• To adjust the raker
clearance you will need a
FLAT FILE and a RAKER
GAUGE.
• Place the gauge over the
raker lip.
• 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.
STOP

SAFETY INSTRUCTIONS
4 Lubricating cutting equipment
Poor lubrication of cutting equipment may
cause the chain to snap and lead to serious,
even fatal injuries.
3 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 saw 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.
!
A slack chain may jump off and cause serious
or even fatal injury.
Prolonged inhalation of exhaust gases from
the engine, chain lubrication oil mist and/or
saw dust can be unhealthy.
!
A Chain oil
• Chainsaw chain oil must demonstrate good adhesion to the
chain and also maintain its flow caracteristics regardless of
whether it is warm summer or cold winter weather.
• As a chainsaw manufacturer we have developed an optimal
chain oil which, with its vegetable oil base, is also
biodegradable. 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.
• In areas where oil specifically for lubrication of saw chains is
unavailable, ordinary EP 90 transmission oil may be used.
•Never use waste oil!
It is damaging to you, the saw and the environment.
B Filling with chain oil
• The saw is equipped with
automatic chain lubrication.
The oil flow is adjustable.
• The sizes of the chain oil
tank and fuel tank have
been chosen so that the
saw will run out of fuel
before running out of oil.
This means that you should
never run with a dry chain.
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). You should also use the
recommended cutting
equipment (a bar that is too
long will use more chain oil).
The above conditions also
apply to models with an
adjustable oil pump.
STOP
1. Use the combination
spanner to loosen the bar
nut that holds the clutch
cover and chain brake.
Then retighten the nut
finger-tight by hand.
2. Raise the tip of the bar
and stretch the chain by
tightening the chain
tensioning screw with the
combination spanner.
Tighten the chain until
there is no slack on the
underside of the bar.
3. Keep the tip of the bar
raised, and use the
combination spanner to
tighten the bar nut. Check
that you can pull the chain
round freely by hand, and
that there is still no slack
under the bar.
The position of the chain tensioning screw varies from
model to model. See the
” What is what” section to find out
where it is on your saw.

English – 15
C Checking chain lubrication
• Check the chain lubrication
each time you refuel.
Aim the tip of the saw at a
light coloured surface about
20 cm 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:
1 Check that the oil channel
in the bar is not
obstructed. Clean if
necessary.
2 Check that the groove in
the edge of the bar is
clean. Clean if necessary.
3 Check that the bar tip
sprocket turns freely and
that the lubricating hole in
the tip is not blocked.
Clean and lubricate if
necessary.
If the chain lubrication
system is still not working
after carrying out the
above measures you
should contact your
service agent.
D Lubricating the bar tip sprocket
• Lubricate the bar tip
sprocket each time you
refuel. Use the special
grease gun and a good
quality bearing grease.
SAFETY INSTRUCTIONS
E Checking wear on cutting equipment
Saw chain
Check the saw chain daily for:
• Visible cracks in rivets and
links.
• Whether the chain is stiff.
• Whether rivets and links are
badly worn.
We recommend you
compare the existing chain
with a new chain to decide
how badly it is worn.
When the length of the
cutting teeth has worn down
to only 4 mm the chain must
be replaced.
F Chain drive sprocket
Regularly check the
degree of wear on the
drive sprocket. Replace if
wear is excessive.
min 4 mm
(0,16")
STOP
STOP
STOP

16– English
G Bar
Check regularly:
• Whether there are burrs on
the edges of the bar.
Remove these with a file if
necessary.
• 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 one side of
the bar tip this is due to a
slack chain.
• To prolong the life of the bar
you should turn it over daily.
MOST CHAIN SAW ACCIDENTS HAPPEN
WHEN THE CHAIN TOUCHES THE OPERA-
TOR.
• WEAR PERSONAL PROTECTIVE EQUIPMENT
(see the section on
”Chain saw safety
equipment”
).
• DO NOT TACKLE ANY JOB YOU ARE UNSURE OF
(see the section on
”Personal protective
equipment” , ”How to avoid kickback”, ” General
working instructions”
and ”Cutting equipment” ).
• AVOID SITUATIONS WHERE THERE IS A RISK OF
KICKBACK (see the section on
”Personal
protective equipment”
).
• USE THE RECOMMENDED PROTECTIVE
EQUIPMENT AND CHECK ITS CONDITION (see
section on
”General working instructions” ).
• CHECK THAT ALL SAFETY FUNCTIONS ARE
WORKING (see section on
”General working
instructions”
and ”General safety precautions” ).
SAFETY INSTRUCTIONS
!
HOWTOAVOIDKICKBACK
Kickback can happen very suddenly and
violently; kicking the saw, bar and chain back
at the user. If this happens when the chain is
moving it can cause very serious, even fatal
injuries. It is vital you understand what causes
kickback and that you can avoid it by taking
care and using the right working technique.
Working one-handed is dangerous and
increases the risk of kickback.
What is kickback?
The word kickback is used to
describe the sudden reaction
that happens when the upper
quadrant of the tip of the bar
(known as the “kickback zone”)
touches an object and the
saw is kicked backwards.
Kickback always occurs in
the cutting plane of the saw.
Normally the saw and bar are
thrown backwards and
upwards towards the user.
However the 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.
Kickback only occurs if the
kickback zone of the bar
touches an object.
!
STOP

English – 17
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.
2 The saw should always
be held in a firm grip, with
the right hand on the rear
handle and the left hand
on the front handle. Wrap
your fingers and thumb
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 saw under control. One-handed working may be
necessary, but should only be carried by persons who are
trained and have knowledge of tree maintenance work
using a chain saw, both above and on the ground. Do not
let go of the handles!
3 Most kickback accidents
happen during limbing.
Make sure that you are in
a stable position and that
nothing can make you
lose your balance.
Lack of concentration can
mean that the kickback
zone of the bar
accidentally touches a
branch, a nearby tree or
another object, causing
kickback.
4 The chain saw should not
be used above shoulder
height. Avoid cutting with
the guide bar tip.
SAFETY INSTRUCTIONS
Warning!
Working one-handed is dangerous and should
only be carried out by persons who are
trained in this special working method.
When performing tree maintenance work one-
handed, cutting equipment can more easily
slide or bounce on a stem or branch,
increasing the risk of kickback.
Take care to insure that the saw falls under its
own weight when finishing a pruning cut.
Work should therefore always be carried out
with the saw in such a position that the body
is always clear of the cutting equipment.
If it is necessary to cut
branches or similar which
are above shoulder
height, a lift platform or
scaffold tower is
recommended.
5 Always use a fast cutting
speed, i.e. full throttle.
6 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 saw back
towards the user.
Unless the user resists
this pushing force there is
a risk that the saw will
move so far backwards
that only the kickback
zone of the bar is in
contact with the tree. This
will cause kickback.
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 saw pulls
itself towards the tree and
the front edge of the saw
provides a natural rest
when cutting. Cutting on
the pull stroke gives you
better control over the
saw and the position of
the kickback zone.
7 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 the
sections on
”Cutting equipment” and ”Technical data”.
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!

working one-handed can
occur, should only be
carried out by persons
with experience of and
training in:
• tree maintenance
• climbing techniques
• safety instructions for
climbing
• extra safety
equipment, such as
harnesses, loops,
straps, ropes, safety
hooks and other anti-fall
measures
for both the chain saw
and operator.
4 Always wear suitable protective clothing. See the section
on
”Personal protective equipment” .
5 Never use a chain saw that has been modified in any way
from its original specification.
6 Never use a chain saw
that is faulty. Carry out
the regular checks,
maintenance and service
routines described in this
manual. Some
maintenance and service
measures must be carried
out by trained specialists.
See the section on
”Maintenance” .
!Warning!
Never start the saw without first activating
the chain brake!
• Never start a chain saw
unless the bar, chain and
clutch cover are fitted
correctly. (See section on
”Assembly” ).
• Never start a chain saw
indoors. Exhaust fumes can
be dangerous.
• Before starting the saw
make sure there are no
people or animals nearby
who might be put at risk.
• Place the chain saw on the
ground with your right knee
on the rear handle. Activate
the chain brake by pushing
the front hand guard
forward. Grasp the front
handle firmly using your left
hand. Make sure the chain
saw is steady and the chain
is not touching the ground.
Then grasp the starter
handle and pull the starter
cord.
Prolonged inhalation of exhaust gases from
the engine, chain lubrication oil mist and/or
saw dust can be unhealthy.

8 FUEL SAFETY
(Refuelling, fuel mixture, storage.)
Fuel and fuel vapour are highly inflammable.
Take care when handling fuel and chain oil.
Keep away from naked flames and do not
breathe in fuel vapour.
• Never try to refuel the saw
while it is running.
• Stop the engine and let it
cool for a few minutes
before refuelling.
• Make sure there is plenty of
ventilation when refuelling
or mixing fuel (2-stroke
mixture).
• Move the saw at least 3 m
from the refuelling point
before starting it.
• Never start the chainsaw:
a) If you have spilt fuel or
chain oil on the saw.
Wipe off the spill and
allow remaining fuel to
evaporate.
b) If you spill fuel or chain
oil on yourself or your
clothes. Change your
clothes.
c) If there is a fuel leak.
Check regularly for
leaks from the
FUEL CAP and FUEL
LINES.
• Always store the chain saw and fuel away from any sources
of sparks or naked flames, e.g. machines, electric motors,
relays, switches, boilers, etc.
• Always store fuel in an approved container designed for
that purpose.
• For longer periods of storage or for transport of the saw, the
fuel and chain oil tanks should be emptied. Ask where you
can dispose of waste fuel and chain oil at your local petrol
station.
9 Never use any accessories other than those recommended
in this manual. See the sections on
”Cutting equipment”
and ”Technical data” .
The risk of accident is increased if you use the
wrong cutting equipment or a chain that is not
sharpened correctly. Using the wrong combi-
nation of bar and chain can increase the risk
of accidents!

SAFETY INSTRUCTIONS
GENERAL WORKING INSTRUCTIONS
This section describes basic safety rules for
using a chain saw. This information is no
substitute for professional skills and
experience. If you get into a situation where
you feel unsafe, stop and seek expert advice
(look under FORESTRY SERVICES in the
telephone directory).
DO NOT ATTEMPT ANY TASK THAT YOU
FEEL UNSURE OF!
Important
1 Before using a chain saw you must understand the effects
of kickback and what causes it. (See the section on
”How to
avoid kickback”. )
2 Before using a saw you must understand the difference
between sawing with the top and bottom edges of the bar.
(See the section on
”How to avoid kickback”. )
3 Tree maintenance work with a chainsaw above ground
level, in which working one-handed can occur, should only
be carried out by persons with experience of and training
in:
• tree maintenance
• climbing techniques
• safety instructions for climbing
• extra safety equipment, such as harnesses, loops,
straps, ropes, safety hooks and other anti-fall measures
for both the chain saw and operator.
4 During tree maintenance work above ground level, the
chain saw should be “made safe“. The saw is “made safe“
by attaching a safety line to the fixing loop on the saw.
1 Basic safety rules
1 Look around you:
• To make sure there are no people, animals or other objects
nearby that might affect your work.
• To make sure that none of the above might come within
reach of your saw or be hit by a falling tree or a falling
branch, and be injured.
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.
2 All tree maintenance work above ground level should be
carried out by two or more persons with the appropriate
training (see above, “important“; point 3). At least one
person should be on the ground to carry out rescue
procedures and/or to get help should an emergency arise.
3 During tree maintenance work above ground level, the
working area should always be “secured“ and be marked
out by signs, tape or similar.
The person(s) on the ground should always inform the
person(s) working above before they enter the “secured“
working area.
4 Do not use the saw in bad weather conditions, 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 direction of falling
branches, etc.
5 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.
6 Ensure that you can stand and work safely. Always work
out an free escape route. Look for possible hindrances to
an unexpected move.
7 Take the utmost care
when cutting through
branches or 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.
This could make you lose
control and cause a
serious accident.
8 Before moving your chain
saw switch off the engine
and lock the chain using
the chain brake. Carry the
saw with the bar and
chain pointing backwards.
Fit a guard to the bar
before carrying the saw
any distance.
9 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.
