GENERAL SAFETY PRECAUTIONS
8 – English
Important
Always use common sense
It is not possible to cover every conceivable situation you
can face when using a chain saw. Always exercise care
and use your common sense. Avoid all situations which
you consider to be beyond your capability. If you still feel
uncertain about operating procedures after reading these
instructions, you should consult an expert before
continuing. Do not hesitate to contact your dealer or us if
you have any questions about the use of the chain saw.
We will willingly be of service and provide you with advice
as well as help you to use your chain saw both efficiently
and safely. Attend a training course in chain saw usage if
possible. Your dealer, forestry school or your library can
provide information about which training materials and
courses are available.
Work is constantly in progress to improve the design and
technology - improvements that increase your safety and
efficiency. Visit your dealer regularly to see whether you
can benefit from new features that have been introduced.
Personal protective equipment
Approved protective helmet
Hearing protection
Protective goggles or a visor
Gloves with saw protection
Trousers with saw protection
Use appropriate protections for arm.
Boots with saw protection, steel toe-cap and non-slip
sole
Always have a first aid kit nearby.
IMPORTANT!
This chain saw for tree service is designed for pruning
and dismantling standing tree crowns.
You should only use the saw with the bar and chain
combinations we recommend in the chapter Technical
data.
Never use the machine if you are fatigued, while under
the influence of alcohol or drugs, medication or anything
that could affect your vision, alertness, coordination or
judgement.
Wear personal protective equipment. See instructions
under the heading ”Personal protective equipment”.
Do not modify this product or use it if it appears to have
been modified by others.
Never use a machine that is faulty. Carry out the checks,
maintenance and service instructions described in this
manual. Some maintenance and service measures
must be carried out by trained and qualified specialists.
See instructions under the heading Maintenance.
Never use any accessories other than those
recommended in this manual. See instructions under
the headings Cutting equipment and Technical data.
CAUTION! Always wear protective glasses or a face
visor to reduce the risk of injury from thrown objects. A
chain saw is capable of throwing objects, such as wood
chips, small pieces of wood, etc, at great force. This can
result in serious injury, especially to the eyes.
!
WARNING! Running an engine in a
confined or badly ventilated area can
result in death due to asphyxiation or
carbon monoxide poisoning.
!
WARNING! Faulty cutting equipment or
the wrong combination of bar and saw
chain increases the risk of kickback!
Only use the bar/saw chain combinations
we recommend, and follow the filing
instructions. See instructions under the
heading Technical data.
!
WARNING! Most chain saw accidents
happen when the chain touches the
operator. You must use approved
personal protective equipment whenever
you use the machine. Personal protective
equipment cannot eliminate the risk of
injury but it will reduce the degree of
injury if an accident does happen. Ask
your dealer for help in choosing the right
equipment.
CAUTION! Never use a chain saw by holding it with one
hand. A chain saw is not safely controlled with one
hand; you can cut yourself. Always have a secure, firm
grip around the handles with both hands.
GENERAL SAFETY PRECAUTIONS
English

Fire Extinguisher and Shovel
Generally clothes should be close-fitting without
restricting your freedom of movement.
This top handle chainsaw is designed specifically for tree
surgery and maintenance in the tree. Due to the special
compact handle design (closely spaced handles), there is
an increased risk of losing control. For this reason these
special chainsaws should be used only for work in a tree
by persons who are trained in special cutting and working
techniques and who are properly secured (lift bucket,
ropes, safety harness). Regular chainsaws (with wider
spaced handles) are recommended for all other cutting
work at ground level.
Machine
′′
s safety equipment
In this section the machine’s safety features and their
function are explained. For inspection and maintenance
see instructions under the heading Checking, maintaining
and servicing chain saw safety equipment. See
instructions under the heading, What is what?, to find
where these parts are located on your machine.
The life span of the machine can be reduced and the risk
of accidents can increase if machine maintenance is not
carried out correctly and if service and/or repairs are not
carried out professionally. If you need further information
please contact your nearest servicing dealer.
Chain brake and front hand guard
Your chain saw is equipped with a chain brake that is
designed to stop the chain if you get a kickback. The chain
brake reduces the risk of accidents, but only you can
prevent them.
Take care when using your saw and make sure the
kickback zone of the bar never touches any object.
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 your left hand hitting the chain if
you lose grip of the front handle.
IMPORTANT! Sparks can come from the muffler, the bar
and chain or other sources. Always have fire
extinguishing tools available if you should need them.
Help prevent forest fires.
!
WARNING! Working in a tree requires the
use of special cutting and working
techniques which must be observed in
order to reduce the increased risk of
personal injury. Never work in a tree
unless you have received specific,
professional training for such work,
including training in the use of safety
and other climbing equipment, such as
harnesses, ropes, belts, climbing irons,
snap hooks, carabiners, etc.
!
WARNING! Never use a machine with
defective safety components. Safety
equipment must be inspected and
maintained. See instructions under the
heading Checking, maintaining and
servicing chain saw safety equipment. If
your machine does not pass all the
checks, take the saw to a servicing
dealer for repair.

A
GENERAL SAFETY PRECAUTIONS
10 – English
The chain brake must be engaged when the chain
saw is started to prevent the saw chain from rotating.
Use the chain brake as a ”parking brake” when
starting and when moving over short distances, to
reduce the risk of moving chain accidentally hitting
your leg or anyone or anything close by.
To release the chain brake pull the front hand guard
backwards, towards the front handle.
Kickback can be very sudden and violent. Most
kickbacks are minor and do not always activate the
chain brake. If this happens you should hold the chain
saw firmly and not let go.
The way the chain brake is activated, either manually
or automatically by the inertia release mechanism,
depends on the force of the kickback and the position
of the chain saw in relation to the object that the
kickback zone of the bar strikes.
If you get a violent kickback while the kickback zone of
the bar is farthest away from you the chain brake is
designed to be activated by the inertia in the kickback
direction.
If the kickback is less violent or the kickback zone of
the bar is closer to you the chain brake is designed to
be activated manually by the movement of your left
hand.
In the felling position the left hand is in a position that
makes manual activation of the chain brake
impossible. With this type of grip, that is when the left
hand is placed so that it cannot affect the movement
of the front hand guard, the chain brake can only be
activated by the inertia action.
Will my hand always activate the chain
brake during a kickback?
No. It takes a certain force to move the hand guard
forward. If your hand only lightly touches the front guard
or slips over it, the force may not be enough to trigger the
chain brake. You should also maintain a firm grip of the
chain saw handles while working. If you do and
experience a kickback, your hand may never leave the
front handle and will not activate the chain brake, or the
chain brake will only activate after the saw has swung
around a considerable distance. In such instances, the
chain brake might not have enough time to stop the saw
chain before it touches you.
There are also certain positions in which your hand
cannot reach the front hand guard to activate the chain
brake; for example, when the saw chain is held in felling
position.
GENERAL SAFETY PRECAUTIONS
English
11
Will my inertia activated chain brake
always activate during kickback in the
event of a kickback?
No. First your brake must be in working order. Second the
kickback must be strong enough to activate the chain
brake. If the chain brake is too sensitive it would activate
all the time which would be a nuisance.
Will my chain brake always protect me
from injury in the event of a kickback?
No. First, the chain brake must be in working order to
provide the intended protection. Second, it must be
activated during the kickback as described above to stop
the saw chain. Third, the chain brake may be activated but
if the bar is too close to you the brake might not have
enough time to slow down and stop the chain before the
chain saw hits you.
Only you and proper working technique can eliminate
kickback and its danger.
Throttle lockout
The throttle lockout is designed to prevent accidental
operation of the throttle control. When you press the lock
(A) (i.e. when you grasp the handle) it releases the throttle
control (B). When you release the handle the throttle
control and the throttle lockout both move back to their
original positions. This arrangement means that the
throttle control is automatically locked at the idle setting.
Chain catcher
The chain catcher is designed to catch the chain if it snaps
or jumps off. This should not happen if the chain is
properly tensioned (see instructions under the heading
Assembly) and if the bar and chain are properly serviced
and maintained (see instructions under the heading
General working instructions).
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to reduce vibration and make
operation easier.
The machine
s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine
s handle unit. The body of the
chain saw, including the cutting equipment, is insulated
from the handles by vibration damping units.
Cutting hardwoods (most broadleaf trees) creates more
vibration than cutting softwoods (most conifers). Cutting
with cutting equipment that is blunt or faulty (wrong type
or badly sharpened) will increase the vibration level.
Stop switch
Use the stop switch to switch off the engine.
A
B
!
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.
GENERAL SAFETY PRECAUTIONS
12 – English
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
In areas with a hot, dry climate there is a high risk of fires.
These areas are sometimes subject to government rules
requiring among other things the muffler must be
equipped with an approved type of spark arrestor 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.
General rules
Only use cutting equipment recommended by us!
See instructions under the heading Technical data.
Keep the chain’s cutting teeth properly
sharpened! Follow our instructions and use the
recommended file gauge.
A damaged or badly
sharpened chain increases the risk of accidents.
Maintain the correct depth gauge setting! Follow
our instructions and use the recommended depth
gauge clearance.
Too large a clearance increases
the risk of kickback.
Keep the chain properly tensioned!
If the chain is
slack it is more likely to jump off and lead to increased
wear on the bar, chain and drive sprocket.
Keep cutting equipment well lubricated and
properly maintained!
A poorly lubricated chain is
more likely to break and lead to increased wear on the
bar, chain and drive sprocket.
Cutting equipment designed to reduce
kickback
The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything.
By using cutting equipment with ”built-in” kickback
reduction and keeping the chain sharp and well-
maintained you can reduce the effects of kickback.
Guide bar
The smaller the tip radius the lower the chance of
kickback.
Saw chain
A chain is made up of a number of links, which are
available in standard and low-kickback versions.
!
WARNING! The exhaust fumes from the
engine are hot and may contain sparks
which can start a fire. Never start the
machine indoors or near combustible
material!
CAUTION! The muffler gets very hot during and after
use. This also applies during idling. Be aware of the fire
hazard, especially when working near flammable
substances and/or vapours.
!
WARNING! Never use a saw without a
muffler, or with a damaged muffler. A
damaged muffler may substantially
increase the noise level and the fire
hazard. Keep fire fighting equipment
handy. If a spark arrestor screen is
required in your area, never use the saw
without or with a broken spark arrestor
screen.
!
WARNING! Faulty cutting equipment or
the wrong combination of bar and saw
chain increases the risk of kickback!
Only use the bar/saw chain combinations
we recommend, and follow the filing
instructions. See instructions under the
heading Technical data.
IMPORTANT! No saw chain design eliminates the
danger of kickback.
GENERAL SAFETY PRECAUTIONS
English 13
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.
Guide bar
Length (inches/cm)
Number of teeth on bar tip sprocket (T).
Chain pitch (inches). The spacing between the drive
links of the chain must match the spacing of the teeth
on the bar tip sprocket and drive sprocket.
Number of drive links. The number of drive links is
determined by the length of the bar, the chain pitch
and the number of teeth on the bar tip sprocket.
Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
Chain oil hole and hole for chain tensioner. The bar
must be matched to the chain saw design.

Sharpening your chain and adjusting
depth gauge setting
General information on sharpening cutting teeth
Never use a blunt chain. When the chain is blunt you
have to exert more pressure to force the bar through
the wood and the chips will be very small. If the chain
is very blunt it will produce wood powder and no chips
or shavings.
A sharp chain eats its way through the wood and
produces long, thick chips or shavings.
The cutting part of the chain is called the cutter and
consists of a cutting tooth (A) and the depth gauge
(B). The cutters cutting depth is determined by the
difference in height between the two (depth gauge
setting).
When you sharpen a cutting tooth there are four important
factors to remember.
!
WARNING! Any contact with a rotating
saw chain can cause extremely serious
injuries.
GENERAL SAFETY PRECAUTIONS
14 – English
1 Filing angle
2 Cutting angle
3 File position
4 Round file diameter
It is very difficult to sharpen a chain correctly without the
right equipment. We recommend that you use our file
gauge. This will help you obtain the maximum kickback
reduction and cutting performance from your chain.
See instructions under the heading Technical data for
information about sharpening your chain.
Sharpening cutting teeth
To sharpen cutting teeth you will need a round file and a
file gauge. See instructions under the heading Technical
data for information on the size of file and gauge that are
recommended for the chain fitted to your chain saw.
Check that the chain is correctly tensioned. A slack
chain will move sideways, making it more difficult to
sharpen correctly.
Always file cutting teeth from the inside face. Reduce
the pressure on the return stroke. File all the teeth on
one side first, then turn the chain saw and file the teeth
on the other side.
File all the teeth to the same length. When the length
of the cutting teeth is reduced to 5/32 inch (4 mm) the
chain is worn out and should be replaced.
General advice on adjusting depth gauge setting
When you sharpen the cutting tooth (A) the depth
gauge setting (C) will decrease. To maintain optimal
cutting performance the depth gauge (B) has to be
filed down to achieve the recommended depth gauge
setting. See instructions under the heading Technical
data to find the correct depth gauge setting for your
particular chain.
Adjustment of depth gauge setting
The cutting teeth should be newly sharpened before
adjusting the depth gauge setting. We recommend
that you adjust the depth gauge setting every third
time you sharpen the cutting teeth. NOTE! This
recommendation assumes that the length of the
cutting teeth is not reduced excessively.
You will need a flat file and a depth gauge tool. We
recommend that you use our depth gauge tool to
!
WARNING! Departure from the
sharpening instructions considerably
increases the risk of kickback.
!
WARNING! The risk of kickback is
increased if the depth gauge setting is
too large!
GENERAL SAFETY PRECAUTIONS
English 15
acheive the correct depth gauge setting and bevel for
the depth gauge.
Place the depth gauge tool over the chain. Detailed
information regarding the use of the depth gauge tool,
will be found on the package for the depth gauge tool.
Use the flat file to file off the tip of the depth gauge that
protrudes through the depth gauge tool. The depth
gauge setting is correct when you no longer feel
resistance as you draw the file along the depth gauge
tool.
Tensioning the chain
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
Check the chain tension every time you refuel. NOTE! A
new chain has a running-in period during which you
should check the tension more frequently.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand.
Loosen the bar nuts that hold the clutch cover/chain
brake. Use the combination spanner. Then tighten the
bar nuts by hand as tight as you can.
Raise the tip of the bar and stretch the chain by
tightening the chain tensioning screw using the
combination spanner. Tighten the chain until it does
not sag from the underside of the bar.
Use the combination spanner to tighten the bar nuts
while lifting the tip of the bar at the same time. Check
that you can pull the chain round freely by hand and
that it does not sag from the underside of the bar.
The position of the chain tensioning screw on our chain
saws varies from model to model. See instructions under
the heading What is what? to find out where it is on your
model.
Lubricating cutting equipment
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its flow characteristics regardless of
whether it is warm summer or cold winter weather.
As a chain saw manufacturer we have developed an
optimal chain oil which has a vegetable oil base. We
recommend the use of our own oil for both maximum
chain life and to minimise environmental damage. If our
own chain oil is not available, standard chain oil is
recommended.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
!
WARNING! A slack chain may jump off
and cause serious or even fatal injury.
!
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
IMPORTANT! When using vegetable based saw chain
oil, dismantle and clean the groove in the bar and saw
chain before long-term storage. Otherwise there is a risk
of the saw chain oil oxidizing, which will result in the saw
chain becoming stiff and the bar tip sprocket jamming.
GENERAL SAFETY PRECAUTIONS
16 – English
Filling with chain oil
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburetor as
recommended (a 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.
Checking chain lubrication
Check the chain lubrication each time you refuel. See
instructions under the heading Lubricating the bar tip
sprocket.
Aim the tip of the bar at a light coloured surface about
20 cm (8 inches) away. After 1 minute running at 3/4
throttle you should see a distinct line of oil on the light
surface.
If the chain lubrication is not working:
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
Check that the groove in the edge of the bar is clean.
Clean if necessary.
Check that the bar tip sprocket turns freely and that
the lubricating hole in the tip sprocket is not blocked.
Clean and lubricate if necessary.
If the chain lubrication system is still not working after
carrying out the above checks and associated measures
you should contact your servicing dealer.
Chain drive sprocket
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)
Regularly check the degree of wear on the drive sprocket.
Replace if wear is excessive. Replace the drive sprocket
whenever you replace the chain.
Checking wear on cutting equipment
Check the chain daily for:
Visible cracks in rivets and links.
Whether the chain is stiff.
Whether rivets and links are badly worn.
GENERAL SAFETY PRECAUTIONS
English 17
Replace the saw chain if it exhibits any of the points
above.
We recommend you compare the existing chain with a
new chain to decide how badly the existing chain is worn.
When the length of the cutting teeth has worn down to
only 4 mm (5/32 inch) the chain must be replaced.
Guide 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 the underside of the bar tip this is
due to running with a slack chain.
To prolong the life of the bar you should turn it over
daily.

ASSEMBLY
18 – English
Fitting the bar and chain
Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover (chain
brake). Take off the transportation ring (A).
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.
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.
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar. See instructions under the heading
Tensioning the chain.
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.
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.
!
WARNING! Always wear gloves, when
working with the chain.
FUEL HANDLING
English 19
Fuel
Note! The machine is equipped with a two-stroke engine
and must always be run using a mixture of gasoline and
two-stroke 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.
Gasoline
Use good quality unleaded gasoline.
CAUTION! Engines equipped with catalytic
converters must be run on unleaded fuel
mixtures. Leaded gasoline will destroy the catalytic
converter and it will no longer serve its purpose. The
green fuel cap on saws fitted with catalytic converters
means that only unleaded gasoline can be used.
The lowest recommended octane grade is 87
((RON+MON)/2). If you run the engine on a lower
octane grade than 87 so-called knocking can occur.
This gives rise to a high engine temperature and
increased bearing load, which can result in serious
engine damage.
When working with continuous high revs (e.g. limbing)
a higher octane is recommended.
Environment fuel
JONSERED recommends the use of alkylate fuel or
environment fuel for four-stroke engines blended with two-
stroke oil as set out below. Note that carburetor
adjustment may be necessary when changing the type of
fuel (see instructions under the heading Carburetor).
Running-in
Avoid running at a too high speed for extended periods
during the first 10 hours.
Two-stroke oil
For best results and performance use JONSERED
two-stroke engine oil, which is specially formulated for
our air-cooled two stroke-engines.
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
Never use oil intended for four-stroke engines.
Mixing ratio
1:50 (2%) for all engines.
Mixing
Always mix the gasoline and oil in a clean container
intended for fuel.
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.
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.
Chain oil
We recommend the use of special oil (chain oil) with
good adhesion characteristics.
Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
It is important to use oil of the right grade (suitable
viscosity range) to suit the air temperature.
!
WARNING! Always ensure there is
adequate ventilation when handling fuel.

FUEL HANDLING
20 – English
In temperatures below 0°C (32°F) some oils become
too viscous. This can overload the oil pump and result
in damage to the oil pump components.
Contact your service agent when choosing chain oil.
Fueling
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.
Fuel safety
Never refuel the machine while the engine is running.
Make sure there is plenty of ventilation when refuelling
or mixing fuel (petrol and 2-stroke oil).
Move the machine at least 3 m from the refuelling
point before starting it.
Never start the machine:
1 If you have spilled fuel or chain oil on the machine.
Wipe off the spillage and allow remaining fuel to
evaporate.
2 If you have spilled 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.
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.
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 petrol station.
The bar guard must always be fitted to the cutting
attachment when the machine is being transported or
in storage, in order to prevent accident contact with
the sharp chain. Even a non-moving chain can cause
serious cuts to yourself or persons you bump into with
an exposed chain.
Secure the machine during transport.
Long-term storage
Empty the fuel/oil tanks in a well ventilated area. Store the
fuel in approved cans in a safe place. Fit the bar guard.
Clean the machine. See instructions under the heading
Maintenance schedule.
Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
!
WARNING! Taking the following
precautions, will lessen the risk of fire:
Do not smoke and do not place any hot
objects in the vicinity of fuel.
Always stop the engine and let it cool for
a few minutes 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.
!
WARNING! Fuel and fuel vapor are highly
flammable. Take care when handling fuel
and chain oil. Be aware of the risks of
fire, explosion and those associated with
inhalation.
!
WARNING! Never use a machine with
visible damage to the spark plug guard
and ignition cable. A risk of sparking
arises, which can cause a fire.
