T
In countr ies that have a warm and dry climate there is a
significant risk of fire. We therefore fit certain mufflers with a
spark arrestor mesh. Check whether the muffler on your
machine is fitted with this kind of mesh.
For mufflers it is very important that you follow the instructions
on checking, maintaining and servicing your machine.
Never use a machine that has a faulty muffler.
Blades
o ensure good cutting results it is important that the contact
pressure between the blades is correct. The contact pressure
is adjusted by turning the screws on the underside of the bar
clockwise as far as they will go. Then turn the screws
anticlockwise a 1/4 turn. Lock the screws using the locking nut
on the top of the bar. Check that the screws are loose enough
to allow the washers under the screw heads to slide sideways.
When the blades are correctly adjusted the play between the
blades should be 0,2–0,4 mm, measured at the screws.
The edges of the blades are too hard to be filed. Dull blades
should be sharpened using a grinder.
Replace the blades if they are bent or damaged.
Gear
Regularly check that the muffler is securely attached to the
machine.
If the muffler on your machine is fitted with a spark arrestor
mesh this must be cleaned regularly. A blocked mesh will
cause the engine to overheat and may lead to serious
damage.
WARNING! Mufflers fitted with catalytic
converters get very hot during use and
!
remain so for some time after stopping. This
also applies at idle speed. Contact can result
in burns to the skin. Remember the risk of
fire!
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear housing.
–
WARNING! The inside of the muffler contain
chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a
damaged muffler.
WARNING! Bear in mind that:
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!

FUEL HANDLING
Fuel safety
Never start the machine:
1 If you have spilt fuel on it. 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.
Transport and storage
• Store and transport the machine and fuel so that there is
no risk of any leakage or fumes coming into contact with
sparks or naked flames, for example, from electrical
machinery, electric motors, electrical relays/switches or
boilers.
• When storing and transporting fuel always use approved
containers intended for this purpose.
• When storing the machine for long periods the fuel tank
must be emptied. Contact your local petrol station to find
out where to dispose of excess fuel.
• Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
• The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.
• Secure the machine during transport.
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and
!
inhaling fumes.
Fuel
NB! The machine is equipped with a two-stroke engine and
must always been run using a mixture of petrol 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.
WARNING! Fuel and fuel fumes are highly
inflammable and can cause serious injury
!
when inhaled or allowed to come in contact
with the skin. For this reason observe
caution when handling fuel and make sure
there is adequate ventilation.
Petrol
NB! Always use a quality petrol/oil mixture at least 90 octane
(RON). If your machine is equipped with a catalytic converter
(see chapter on Technical data) always use a good quality
unleaded petrol/oil mixture. Leaded petrol will destroy the
catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if it is
available.
• The lowest octane recommended is 90 (RON). If you run
the engine on a lower octane grade than 90 so-called
knocking can occur. This gives rise to a high engine
temperature, which can result in serious engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
Two-stroke oil
• For best results and performance use JONSERED twostroke engine oil, which is specially formulated for our aircooled 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%) with JONSERED two-stroke oil.
1:33 (3%) with oils class JASO FB or ISO EGB formulated
for air-cooled, two-stroke engines.

FUEL HANDLING
Mixing
• Always mix the petrol and oil in a clean container intended
for fuel.
• Always start by filling half the amount of the petrol to be
used. Then add the entire amount of oil. Mix (shake) the
fuel mixture. Add the remaining amount of petrol.
• 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.
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.
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.
• Always use a fuel container with an anti-spill valve.
• Clean the area around the fuel cap. Contamination in the
tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the container
before filling the tank.
12 – English

16 – English
MAINTENANCE
Carburettor
Your Jonsered product has been designed and manufactured
to specifications that reduce harmful exhaust fumes. The
engine will be run in after it has used 8-10 tanks of fuel. To
ensure that the engine runs at peak performance and
produces as little harmful exhaust fumes as possible after the
running-in period, ask your dealer/service workshop (which
has a rev counter for this purpose) to adjust your carburettor.
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.
• Adjusting the carburettor means that the engine is
adapted to local operating conditions, e.g. climate,
altitude, petrol and the type of 2-stroke oil.
Adjusting the idle speed
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.
Before any adjustments are made, make sure that the air filter
is clean and the air filter cover is fitted.
Adjust the idle speed with the idle adjustment screw T, if
adjustment is necessary. First turn the idle adjustment screw
T clockwise until the blades start to move. Then turn the idle
adjustment screw T anticlockwise until the blades stop. The
idle speed is correctly adjusted when the engine runs
smoothly in every position. There should also be a clear
margin to the speed at which the blades start to move. The
blades must also remain stationary when the choke control is
in the start throttle position.
Muffler
CAUTION! Some mufflers are fitted with a catalytic
converter. See chapter on Technical data to see whether your
machine is fitted with a catalytic converter.
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.
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.
On mufflers without a catalytic converter the mesh should be
cleaned weekly, or replaced if necessary. On mufflers fitted
with a catalytic converter the mesh should be checked, and if
necessary cleaned, monthly. If the mesh is damaged it
should be replaced. If the mesh is frequently blocked, this
can be a sign that the performance of the catalytic converter
is impaired. Contact your dealer to inspect the muffler. A
blocked mesh will cause the machine to overheat and result
in damage to the cylinder and piston. See also instructions
under the heading Maintenance.
CAUTION! Never use a machine with a defective muffler.
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
!
stops, contact your dealer/service
workshop. Do not use the machine until it
has been correctly adjusted or repaired.
WARNING! Mufflers fitted with catalytic
converters get very hot during use and
!
remain so for some time after stopping. This
also applies at idle speed. Contact can result
in burns to the skin. Remember the risk of
fire!
English – 17
MAINTENANCE
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
2
1
The cooling system consists of:
1 Cooling fins on the cylinder.
2 Cylinder cover (directs cold air over the cylinder).
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.
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
• Unnecessary wear to engine parts.
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if conditions
are exceptionally dusty.
Spark plug
The spark plug condition is influenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type of
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 0,6-0,7 mm. The spark plug should
be replaced after about a month in operation or earlier if
necessary.
0,6 - 0,7 mm
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry before
refitting it.
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.
If the machine is used in dusty conditions the air filter should
be soaked in oil. See instructions under the heading Oiling the
air filter.
Oiling the air filter
Always use special filter oil. Filter oil contains a solvent to
make it spread evenly through the filter. You should therefore
avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.
Check that the spark plug is fitted with a suppressor.

MAINTENANCE
Gear
There are three grease nipples on the gearbox. Use a grease
gun to top up with grease. This should be carried out after
approximately every 20 working hours. Use Jonsered special
grease.
Cleaning and lubrication
Clean any resin and plant residue from the blades using
cleaning agent before and after using the machine.
Lubricate the blade bars with special grease before long
periods of storage.

Make sure the throttle trigger lock and the throttle function correctly from a
safety point of view.
Check that the stop switch works correctly. X
Check that the blades do not move when the engine is idling or when the
choke is in the start throttle position.
Check that the blades are undamaged and show no signs of cracking or
other damage. Replace the blades if necessary.
Clean the air filter. Replace if necessary. X
Check that nuts and screws are tight. X
Check that there are no fuel leaks from the engine, tank or fuel lines. X
Check the starter and starter cord. X
Clean the outside of the spark plug. Remove it and check the electrode
gap. Adjust the gap to 0,6 mm or replace the spark plug. Check that the
spark plug is fitted with a suppressor.
Clean the machine’s cooling system. X
Clean or replace the spark arrestor mesh on the muffler (only applies to
mufflers without a catalytic converter).
Clean the outside of the carburettor and the space around it. X
Fill the gear housing with grease. This should be carried out approximately
every 20 working hours.
Check that the screws that hold the blades together are correctly
tightened.
Clean the fuel tank. X
Check the fuel filter from contamination and the fuel hose from cracks or
other defects. Replace if necessary.
Check all cables and connections. X
Check the clutch, clutch springs and the clutch drum for wear. Replace if
necessary by an autorized service workshop.
Replace the spark plug. Check that the spark plug is fitted with a
suppressor.
