GENERAL SAFETY PRECAUTIONS  
Never use a machine that has a faulty muffler.  
Vibration damping system  
Your machine is equipped with a vibration damping system  
that is designed to reduce vibration and make operation  
easier.  
The machines vibration damping system reduces the transfer  
of vibration between the engine unit/cutting equipment and  
the machines handle unit. The engine body including the  
blades is suspended on the handlebar system via a four  
springs.  
Regularly check that the muffler is securely attached to the  
machine.  
If the muffler on your machine is fitted with a spark arrestor  
screen this must be cleaned regularly. A blocked screen will  
cause the engine to overheat and may lead to serious  
damage.  
Regularly check the vibration damping units for cracks or  
deformation. Check that the vibration damping element is  
undamaged and securely attached.  
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.  
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!  
!
Muffler  
WARNING! The inside of the muffler contain  
chemicals that may be carcinogenic. Avoid  
contact with these elements in the event of a  
damaged muffler.  
!
The muffler is designed to keep noise levels to a minimum  
and to direct exhaust fumes away from the user. A muffler  
fitted with a catalytic converter is also designed to reduce  
harmful exhaust gases.  
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!  
In countries that have a warm and dry climate there is a  
significant risk of fire. We therefore fit certain mufflers with a  
spark arrestor screen. Check whether the muffler on your  
machine is fitted with this kind of screen.  
For mufflers it is very important that you follow the instructions  
on checking, maintaining and servicing your machine.

GENERAL SAFETY PRECAUTIONS  
Blades  
To 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.  
Blade guard  
The blade guard (A) is intended to protect against any part of  
the body coming into contact with the blades (B).  
A
B
Check that the blade guard is not damaged or distorted.  
Replace the blade guard if it is bent or damaged.  
Gear housing  
The gear housing gets hot when the machine has been in  
use. To avoid burning yourself do not touch the gear housing.

If you have spilled fuel on it.Wipe off the spillage and allow  
remaining fuel to evaporate.  
CAUTION! Always use a quality gasoline/oil mixture with an  
octane rating of at least 87 octane ((RON+MON)/2). If your  
machine is equipped with a catalytic converter (see chapter  
on Technical data) always use a good quality unleaded  
gasoline/oil mixture.Leaded gasoline will destroy the catalytic  
converter.  
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.  
Use low-emission gasoline, also known as alkylate gasoline,  
if it is available.  
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.  
This engine is certified to operate on unleaded gasoline.  
The lowest recommended octane grade is 87  
When storing the machine for long periods the fuel tank  
must be emptied.Contact your local gas station to find out  
where to dispose of excess fuel.  
((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.  
Ensure the machine is cleaned and that a complete  
service is carried out before long-term storage.  
When working at continuous high revs a higher octane  
rating is recommended.  
The transport guard must always be fitted to the cutting  
attachment when the machine is being transported or in  
storage.  
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.  
WARNING! Take care when handling fuel.  
Bear in mind the risk of fire, explosion and  
inhaling fumes.  
!
Never use two-stroke oil intended for water-cooled  
engines, sometimes referred to as outboard oil (rated  
TCW).  
Fuel  
Never use oil intended for four-stroke engines.  
Mixing ratio  
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.

MAINTENANCE  
Carburetor  
Muffler  
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.  
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.  
WARNING! The complete clutch cover and  
gear housing must be fitted before the  
machine is started, otherwise the clutch may  
come loose and cause personal injury.  
!
Function  
The carburetor governs the engine’s speed via the throttle  
control. Air and fuel are mixed in the carburetor. The air/  
fuel mixture is adjustable. Correct adjustment is essential  
to get the best performance from the machine.  
Some mufflers are equipped with a special spark arrestor  
screen. If your machine has this type of muffler, you should  
clean the screen at least once a week.This is best done with  
a wire brush.  
The setting of the carburetor means that the engine is  
adapted to local conditions, for example, the climate,  
altitude, fuel and the type of 2-stroke oil.  
On mufflers without a catalytic converter the screen should be  
cleaned weekly, or replaced if necessary. On mufflers fitted  
with a catalytic converter the screen should be checked, and  
if necessary cleaned, monthly. If the screen is damaged it  
should be replaced. If the screen 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 screen will cause the machine to overheat and result  
in damage to the cylinder and piston. See also instructions  
under the heading Maintenance.  
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.  
CAUTION! Never use a machine with a defective muffler.  
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.  
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!  
!
T
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.

MAINTENANCE  
Cooling system  
Air filter  
To keep the working temperature as low as possible the  
machine is equipped with a cooling system.  
The air filter must be regularly cleaned to remove dust and dirt  
in order to avoid:  
Carburettor malfunctions  
Starting problems  
Loss of engine power  
1
Unnecessary wear to engine parts  
Excessive fuel consumption.

3
Fins on the flywheel.  
Cooling fins on the cylinder.  
Cylinder cover (directs cold air over the cylinder).  
Cleaning the air filter  
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.  
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.  
Spark plug  
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.  
The spark plug condition is influenced by:  
Incorrect carburetor adjustment.  
Oiling the air filter  
An incorrect fuel mixture (too much or incorrect type of  
oil).  
A dirty 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.  
These factors cause deposits on the spark plug electrodes,  
which may result in operating problems and starting  
difficulties.  
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.  
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 0.7 mm (0,028"). The spark plug  
should be replaced after about a month in operation or earlier  
if necessary.  
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 housing  
There is a grease nipple and a plug for filling lubricant on the  
gear housing.Use a grease gun to fill with grease.This should  
be done after every 60 working hours. Use Jonsered special  
grease.  
CAUTION! The gear housing must not be filled completely  
with grease. The grease expands as the machine heats up  
during operation. If the gear housing was completely filled  
with grease it could damage the seals and lead to leakage of  
grease.  
The grease in the bevel gear does not normally need to be  
changed except if repairs are carried out.  
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.  
IMPORTANT! Use only JONSERED replacement parts.  
Use of other brands of replacement parts can cause  
damage to your unit or injury to the operator or others.Your  
warranty does not cover damage or liability caused by the  
use of accessories and/or attachments not specifically  
recommended by JONSERED.
