be checked. See instructions under the heading
Maintenance.
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
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.
Stop switch
Use the stop switch to switch off the engine.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
Cutting attachment guard
WARNING! Overexposure to vibration
can lead to circulatory damage or nerve
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.
!
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.
Quick release
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
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
under the heading Adjusting the harness and brush
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.

GENERAL SAFETY PRECAUTIONS
cutter. Certain harnesses also have a quick release fitted
to the support hook.
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.
Check that the harness straps are correctly positioned.
Once the harness and machine have been adjusted,
check that the harness quick release works correctly.
WARNING! Mufflers fitted with catalytic
converters get very hot during use and

can result in burns to the skin.
Remember the risk of fire!
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! The inside of the muffler
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
!
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!
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 mesh. Check whether the muffler on your
machine is fitted with this kind of mesh.
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. See instructions under the heading Checking,
maintaining and servicing the machine’s safety
equipment.
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.)
Never use a machine that has a faulty muffler.
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

GENERAL SAFETY PRECAUTIONS
operate the socket spanner when loosening or tightening
the nut.
WARNING! Always stop the engine
before doing any work on the cutting
attachment.This continues to rotate even
after the throttle has been released.
Ensure that the cutting attachment has
stopped completely and disconnect the
HT lead from the spark plug before you
start to work on it.
!
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.
!
The nylon lining inside the locking nut must not be so worn
that you can turn it by hand. The lining should offer a
resistance of at least 1.5 Nm.The nut should be replaced
after it has been put on approx. 10 times.
Cutting equipment
Saw blades are intended for cutting fibrous types of wood.
Locking screw
The lock screw must be tightened securely for ball-
bearing-mounted support cups.
Grass blades and grass cutters are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.

instructions and use the recommended setting tool. An
incorrectly set saw blade increases the risk of jamming
and blade thrust, and damage to the saw blade.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
•
•
Make sure that the blade is well supported when you
file it. Use a 5.5 mm round file with a file holder.
Sharpening grass cutters and grass
blades
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.
•
•
See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and cutters
using a single-cut flat file.
Sharpen all edges equally to maintain the balance of
the blade.
WARNING! Always discard a blade that is
bent, twisted, cracked, broken or

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.

2
If you have spilt fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
Use low-emission petrol, also known as alkylate petrol, if
it is available.
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.
•
•
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 storing and transporting fuel always use
approved containers intended for this purpose.
When working at continuous high revs a higher octane
rating is recommended.
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.
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.
•
•
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.
•
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
•
Secure the machine during transport.
•
•
Never use oil intended for four-stroke engines.
A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.
WARNING!Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.

Mixing ratio
1:50 (2%) with JONSERED two-stroke oil.
Fuel
1:33 (3%) with oils class JASO FB or ISO EGB
formulated for air-cooled, two-stroke engines.
CAUTION! 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.

personal injury.
IMPORTANT!
This section describes the basic safety precautions for
working with brush cutters and trimmers.
If you encounter a situation where you are uncertain
how to proceed you should ask an expert. Contact your
dealer or your service workshop.
Avoid all usage which you consider to be beyond your
capability.
You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.

Keep a good balance and a firm foothold.
Always hold the machine with both hands. Hold the
machine on the right side of your body.
Basic safety rules
1
•
Look around you:
To ensure that people, animals or other things cannot
affect your control of the machine.
•
To ensure that people, animals, etc., do not come into
contact with the cutting attachment or loose objects
that are thrown out by the cutting attachment.
•
CAUTION! Do not use the machine unless you are
able to call for help in the event of an accident.
2
Inspect the working area. Remove all loose objects,
such as stones, broken glass, nails, steel wire, string,
etc. that could be thrown out or become wrapped
around the cutting attachment.
8
9
Keep the cutting attachment below waist level.

4
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.
Switch off the engine before moving to another area.
Fit the transport guard before carrying or transporting
the equipment any distance.
10 Never put the machine down with the engine running
unless you have it in clear sight.
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.

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.
!
!
Stop the engine and cutting equipment
before you remove material that has
wound around the blade shaft as
otherwise there is a risk of injury.The
bevel gear can get hot during use and may
remain so for a while afterwards.You
could get burnt if you touch it.
WARNING! Watch out for thrown objects.
Always wear approved eye protection.
Never lean over the cutting attachment
guard. Stones, rubbish, etc. can be thrown
up into the eyes causing blindness or
serious injury.
•
•
Clear a strip around 75 m long. Move your fuel can as
work progresses.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be kept outside the safety zone of
15 m. Stop the machine immediately if
anyone approaches. Never swing the
machine around without first checking
behind you to make sure no-one is within
the safety zone.
On sloping ground you should work along the slope. It
is much easier to work along a slope than it is to work
up and down it.
•
You should plan the strip so that you avoid going over
ditches or other obstacles on the ground.You should
also orient the strip to take advantage of wind
conditions, so that cleared stems fall in the cleared
area of the stand.
WARNING! Sometimes branches or
grass get caught between the guard and
cutting attachment. Always stop the
engine before cleaning.
!
Working methods
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.
!
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.
Avoid cutting with the area of the blade
between the 12 o'clock and 3 o'clock
positions. Because of the speed of
rotation of the blade, blade thrust can
occur if you attempt to cut thick stems
with this area of the blade.
•
•
Before you start clearing, check the clearing area, the
type of terrain, the slope of the ground, whether there
are stones, hollows etc.
Start at whichever end of the area is easiest, and clear
an open space from which to work.

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.
•
To fell to the right, the bottom of the tree should be
pushed to the left.Tilt the blade and bring it diagonally
up to the right. Cut with the area of the blade between
3 o’clock and 5 o’clock so that the direction of rotation
of the blade pushes the bottom of the tree to the left.
•
•
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.
Brush cutting with a saw blade
•
Thin stems and brush are mown down. Work with a
sawing movement, swinging sideways.
•
To fell a tree forwards, the bottom of the tree should be
pulled backwards. Pull the blade backwards with a
quick, firm movement.
•
•
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.
•
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

Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
Clearing
•
•
•
Grass blades and grass cutters must not be used on
woody stems.
A grass blade is used for all types of tall or coarse
grass.
The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left is
the clearing stroke and the movement from left-to-
right is the return stroke. Let the left-hand side of the
blade (between 8 and 12 o’clock) do the cutting.
•
The clearing technique removes all unwanted
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.
•
•
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.
Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stroke and stand
firmly again.
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.

stroke.
•
Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the
cut material.

MAINTENANCE
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.
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.
Adjustment of the 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 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.
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.
The carburettor has three adjustment controls:
L = Low speed jet
H = High speed jet
Rec. idle speed: See the Technical data section.
T = Idle adjustment screw
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.
Adjusting the start throttle speed (BC
2145, CC 2145)
•
•
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.
The correct start throttle speed is set by means of an
adjuster on the rear of the handle next to the cable. Use
this screw (5 mm Allen screw) to increase or decrease the
start throttle 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.
Basic setting
•
The basic carburettor settings are adjusted during
testing at the factory. The basic setting is richer than
the optimal setting and should be maintained for the
first few hours the machine is in use. The carburettor
should then be finely adjusted. Fine adjustment
should be carried out by a skilled technician.

Muffler
3
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.

MAINTENANCE
Cleaning the air filter
Bevel gear
Remove the air filter cover and take out the filter. Blow
clean with compressed air.
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.
An oiled foam plastic filter (available as an accessory)
must be used if the machine is operated in extremely
dusty conditions. See instructions under the heading
Oiling the air filter.
Drive shaft
The drive shaft must be greased every three months
during full-time use. Contact your dealer if you are
uncertain about the procedure.
Spark plug
Oiling the air filter
The spark plug condition is influenced by:
•
•
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type of
oil).
Always use special filter oil. Filter oil contains a solvent to
make it spread evenly through the filter.You should
therefore avoid skin contact.
•
A dirty air filter.
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 0.5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary.
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.
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
Winter use
Running problems can occur when using the machine in
the cold and snowy conditions caused by:
•
•
Too low engine temperature.
Icing of the air filter and carburettor.
Special measures are therefore often required:
•
Partly mask the air inlet on the starter to increase the
working temperature of the engine.
•
Preheat the intake air to the carburettor by using the
heat from the cylinder.
°
Temperature 5 C or colder:
The air filter holder is prepared so it can be changed for
use in the cold. Remove the air filter cover and air filter.
Turn the winter cover anticlockwise using a screwdriver so
that the preheated air from the engine can pass inside the
carburettor compartment and prevent, for example, the air
filter from icing up (see figure).
For temperatures below 5°C and/or in snow conditions
there is also:
•
a special cover for the starter housing
These reduce the cooling air and prevent large amounts
of snow from being sucked into the engine.
IMPORTANT! The machine MUST be returned to its
standard design at temperatures warmer than 5°C .
Otherwise there is a risk of overheating resulting in
serious engine damage.
