be checked. See instructions under the heading
Vibration damping system
Maintenance.
Your machine is equipped with a vibration damping
system that is designed to reduce vibration and make
operation easier.
Stop switch
Use the stop switch to switch off the engine.
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration. See
instructions under the heading Cutting equipment.
The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Cutting attachment guard
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
This guard is intended to prevent loose objects from being
thrown towards the operator. The guard also protects the
operator from accidental contact with the cutting
attachment.
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.
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
Quick release
There is an easily accessible, quick release fitted at the
front as a safety precaution in case the engine catches
fire, or in any other situation that requires you to free
yourself from the machine and harness. See instructions

Remember the risk of fire!
WARNING! The inside of the muffler
contain chemicals that may be
!
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
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.
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!
Locking nut
A locking nut is used to secure some types of cutting
attachment.
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine.
When fitting, tighten the nut in the opposite direction to the
direction of rotation of the cutting attachment. To remove
it, undo the nut in the same direction as the cutting
attachment rotates. (CAUTION! The nut has a left-hand
thread.) When loosening and tightening the saw blade
nut, there is a risk of injury from the teeth of the saw blade.
You should therefore always ensure that your hand is
shielded by the blade guard when doing this. Always use
a socket spanner with a shaft that is long enough to allow
this. The arrow in the diagram shows the area where you

Sharpening grass cutters and grass
blades
•
•
See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and cutters
using a single-cut flat file.
•
•
Make sure that the blade is well supported when you
file it. Use a 5.5 mm round file with a file holder.
Sharpen all edges equally to maintain the balance of
the blade.
The filing angle is 15°. File alternate teeth to the right
and those in between to the left. If the blade has been
heavily pitted by stones it may be necessary to dress
the top edges of the teeth with a flat file, in exceptional
cases. If so, this should be done before filing with a
round file. The top edges must be filed down by the
same amount for all the teeth.
WARNING! Always discard a blade that is
bent, twisted, cracked, broken or
!
damaged in any other way. Never attempt
to straighten a twisted blade so that it
can be reused. Only use original blades
of the specified type.
Sharpening the saw blade

GENERAL SAFETY PRECAUTIONS
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.
•
Only use the recommended trimmer heads and
trimmer cords. These have been tested by the
manufacturer to suit a particular engine size. This is
especially important when a fully automatic trimmer
head is used. Only use the recommended cutting
attachment. See the chapter on Technical data.
•
•
Smaller machines generally require small trimmer
heads and vice versa. This is because when clearing
using a cord the engine must throw out the cord
radially from the trimmer head and overcome the
resistance of the grass being cleared.
The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of
the same diameter.
•
•
Make sure that the cutter on the trimmer guard is
intact.This is used to cut the cord to the correct length.
To increase the life of the cord it can be soaked in
water for a couple of days. This will make the line
tougher so that it lasts longer.

FUEL HANDLING
Gasoline
Fuel safety
Never start the machine:
1
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.
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.
Use low-emission gasoline, also known as alkylate
Transport and storage
gasoline, if it is available.
•
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 gas station
to find out where to dispose of excess fuel.
This engine is certified to operate on unleaded
gasoline.
•
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.
•
•
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.

our air-cooled two stroke-engines.
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
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.

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.
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.

•
•
•
Always use the correct equipment.
WARNING! Machines fitted with saw
blades or grass blades can be thrown
violently to the side when the blade
comes into contact with a fixed object.
This is called blade thrust. A blade thrust
can be violent enough to cause the
machine and/or operator to be propelled
in any direction, and possibly lose
control of the machine. Blade thrust can
occur without warning if the machine
snags, stalls or binds. Blade thrust is
more likely to occur in areas where it is
difficult to see the material being cut.
Make sure the equipment is well adjusted.
Follow the safety precautions.
!
Organise your work carefully.
Always use full throttle when starting to cut with the
blade.

•
•
Start at whichever end of the area is easiest, and clear
an open space from which to work.
Work systematically to and fro across the area,
clearing a width of around 4-5 m on each pass. This
exploits the full reach of the machine in both directions
and gives the operator a convenient and varied
working area to work in.
WARNING! Watch out for thrown objects.

To fell a tree forwards, the bottom of the tree should be
pulled backwards. Pull the blade backwards with a
quick, firm movement.
Forestry clearing using a saw blade
•
The risk of blade thrust increases with increasing
stem size.You should therefore avoid cutting with the
area of the blade between 12 o’clock and 3 o’clock.
Large stems must be cut from two sides. First
determine which direction the stem will fall. Make the
first cut on the felling side.Then finish cutting the stem
from the other side. Adjust the cutting pressure to
match the size of the stem and the hardness of the
wood.Small stems require more pressure, while large
stems require less pressure.
•
To fell to the left, the bottom of the tree should be
pushed to the right. Tilt the blade and bring it
diagonally down to the right, exerting firm pressure.At
the same time push the stem using the blade guard.
Cut with the area of the blade between 3 o’clock and
5 o’clock. Apply full throttle before advancing the
blade.
•
•
If the stems are tightly packed, adapt your walking
pace to suit.
If the blade jams in a stem, never jerk the machine
free. If you do this the blade, bevel gear, shaft or
handlebar may be damaged. Release the handles,
grip the shaft with both hands and gently pull the
machine free.

Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the ground.
•
Thin stems and brush are mown down. Work with a
sawing movement, swinging sideways.
Try to cut several stems in a single sawing movement.
With groups of hardwood stems, first clear around the
group. Start by cutting the stems high up around the
outside of the group to avoid jamming. Then cut the
stems to the required height. Now try to reach in with
the blade and cut from the centre of the group. If it is
still difficult to gain access, cut the stems high up and
let them fall. This will reduce the risk of jamming.
Reduce the risk of material wrapping around the blade
by following these instructions:
•
•
1 Always work at full throttle.
2 Avoid the previously cut material during the return
stroke.
•
Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the
cut material.
Grass trimming with a trimmer head
Trimming
•
Hold the trimmer head just above the ground at an
angle. It is the end of the cord that does the work. Let
the cord work at its own pace. Never press the cord
into the area to be cut.
Grass clearing using a grass blade
•
•
The cord can easily remove grass and weeds up
against walls, fences, trees and borders, however it
can also damage sensitive bark on trees and bushes,
and damage fence posts.

vegetation. Keep the trimmer head just above the
ground and tilt it. Let the end of the cord strike the
ground around trees, posts, statues and the like.
CAUTION! This technique increases the wear on the
cord.
•
•
The cord wears quicker and must be fed forward more
often when working against stones, brick, concrete,
metal fences, etc., than when coming into contact with
trees and wooden fences.
When trimming and clearing you should use less than
full throttle so that the cord lasts longer and to reduce
the wear on the trimmer head.
•
If the blade is angled to the left when clearing grass,
the grass will collect in a line, which makes it easier to
collect, e.g. by raking.
English – 25
WORKING TECHNIQUES
Cutting
•
The trimmer is ideal for cutting grass that is difficult to
reach using a normal lawn mower. Keep the cord
parallel to the ground when cutting.Avoid pressing the
trimmer head against the ground as this can ruin the
lawn and damage the tool.
•
Do not allow the trimmer head to constantly come into
contact with the ground during normal cutting.
Constant contact of this type can cause damage and
wear to the trimmer head.
Sweeping
•
The fan effect of the rotating cord can be used for
quick and easy clearing up. Hold the cord parallel to
and above the area to be swept and move the tool to
and fro.
•
When cutting and sweeping you should use full
throttle to obtain the best results.

The basic carburetor settings are adjusted during
testing at the factory. The basic setting is richer than

workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
•
•
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.
The carburetor has three adjustment controls:
L = Low speed jet
Fine adjustment
•
When the machine has been ”run-in” the carburetor
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.
H = High speed jet
T = Idle adjustment screw
Conditions
•
Before any adjustments are made, make sure that the
air filter is clean and the air filter cover is fitted. If you
adjust the carburettor when the air filter is dirty it will
result in a leaner mixture when the filter is finally
cleaned. This can lead to serious engine damage.
•
Carefully turn both jets, L and H, so that they are
midway between fully screwed in and fully screwed
out.
•
•
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 cutting attachment rotates when the
engine is idling the idle adjustment screw T should be
turned anti-clockwise until the cutting attachment
stops.
•
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.

be too high and cause engine damage. Do not let the
engine run at full speed for more than 10 seconds.

Fine adjustment of the idle speed T
Note that the engine should not be under load when you
adjust the high speed jet H.You should therefore remove
the cutting attachment, nut, support flange and drive disc
before adjusting the high speed jet H.
Apply full throttle and turn the high speed jet H very slowly
clockwise until the engine slows down.Then turn the high
speed jet H very slowly anticlockwise until the engine
starts to run unevenly. Now turn the high speed jet H
slowly clockwise a little way until the engine runs
smoothly.
Adjust the idle speed using the idle adjustment screw T, if
it is necessary to readjust. First turn the idle adjustment
screw T clockwise until the cutting attachment starts to
rotate.Then turn the screw anticlockwise until the cutting
attachment stops. The idle speed is correctly adjusted
when the engine will run smoothly in every position. The
idle speed should also be well below the speed at which
the cutting attachment starts to rotate.

stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
When the carburetor is correctly adjusted the machine will
accelerate without hesitation and burble a little at
maximum speed. It is also important that the cutting
attachment does not rotate at idle. If the low speed jet L is
set too lean it may cause starting difficulties and poor
acceleration.
If the high speed jet H is set too lean it will result in less
power, less performance, poor acceleration and/or
damage to the engine.
If both the L and H jets are set too rich it will results in
acceleration problems or too low a working speed.

MAINTENANCE
Oiling the air filter
Bevel gear
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.
The bevel gear is filled with the right amount of grease at
the factory. However, before using the machine you
should check that the bevel gear is filled 3/4 full with
grease. Use JONSERED special grease.
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.
Air filter
Spark plug
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
The spark plug condition is influenced by:
•
•
Incorrect carburetor adjustment.
•
•
•
•
•
Carburettor malfunctions
Starting problems
Loss of engine power
Unnecessary wear to engine parts
Excessive fuel consumption.
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 0.020 inch (0.5
mm). The spark plug should be replaced after about a
month in operation or earlier if necessary.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
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.
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.
Note: 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.
