GENERAL SAFETY PRECAUTIONS
Stop switch
Make sure the engine stops when you push
and hold the stop switch.
Cutting attachment guard
Harness quick release
There is an easily accessible, harness
quick release fitted at the front in case of an
emergency that requires you to free your-
self from the machine and harness.
See instructions under the heading Adjust-
ing the harness.
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.
Check that the guard is undamaged and not
cracked. Replace the guard if it has been
exposed to impact or is cracked.
Always use the recommended guard for the
cutting attachment you are using. See the
"Technical data" section.
I_l ARNING: Never use a cutting
attachment without an approved
guard. See the section on "Technical
data". If an incorrect or faulty guard
is fitted this can cause serious
persona injury.
Use of incorrectly wound trimmer line or an
incorrect cutting attachment increases the
level of vibration.
_ WARNING: Overexposure to
vibration can lead to circulatory
damage or nerve damage in people
who have impaired circulation.
Contact your doctor if you experi-
ence symptoms of overexposure to
vibration. Such symptoms include
numbness, loss of feeling, tingling,
pricking, pain, loss of strength,
changes in skin color or condition.
These symptoms normally appear
in the fingers, hands or wrists. The
risk increases at low temperatures.
Check that the harness straps are correctly
positioned. Once the harness and machine
have been adjusted, check that the harness
quick release works correctIy.
Muffler
The muffier is designed to reduce the noise
level and to direct the exhaust gases away
from the operator.
CAUTION? Muffler is fitted with a catalytic
converter designed to reduce harmful ex-
haust gases.
The muffler on this unit is equipped with a
special spark arrestor mesh. The mesh
should be checked and. if necessary.
cleaned by a servicing dealer. A blocked
mesh will cause the machine to overheat,
which can lead to serious damage. Never
use a muffler with a defective spark arrestor
mesh. See the Maintenance section.
Muffler bolts
_$park arrestor mesh
GENERAL SAFETY PRECAUTIONS
For mufflers, it is very important that you
follow the instructions on checking, main-
taining, and servicing your machine.
Never use a machine that has a faulty
muffler.
0
Regularly check that the muffler is securely
attached to the machine.
_ WARNING: Mufflers fittedwith
catalytic converters get very hot dur-
ing 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!
_ WARNING: The inside of the
muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.
_1 WARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near com-
bustible material!
Locking nut
A locking nut is used to secure some types
of cutting attachment.
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 at-
tachment rotates. (CAUTION! The nut has
a left-hand thread.) Tighten the nut using
the socket spanner.
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 re-
)laced after it has been put on approx. 10
times.
Cutting equipment
This section describes how to choose and
maintain your cutting equipment in order to:
• Reduce the risk of blade thrust.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
IMPORTANT!
Only use cutting attachments with the guards
we recommend! See the section on
"Technical data".
Refer to the instructions for the cutting attach-
ment to check the correct way to load the
trimmer line and the correct line diameter.
Keep the teeth of the blade correctly sharp-
ened! Follow our recommendations. Also re-
fer to the instructions on the blade packaging.
Maintain the correct blade setting! Follow our
instructions and use the recommended file
gauge.
_ WARNING: Always stop the en-
gine 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
lead from the spark plug before
you start to work on it.
_lb WARNING: Using an incorrect
cutting attachment or an incorrect-
ly sharpened blade increases the
risk of kickback.
GENERAL SAFETY PRECAUTIONS
Cutting equipment
Grass blades and grass cutters are in-
tended for cutting coarse grass.
A trimmer head is intended for trimming
grass.
I;t_ :"<h _#
General rules
Only use cutting attachments with the
guards we recommend! See the section on
Technical data.
Keep the teeth of the blade correctly sharp-
ened! Follow our instructions and use the
recommended file gauge. An incorrectly
sharpened or damaged blade increases the
risk of accidents.
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.
• Sharpen all edges equally to maintain the
balance of the blade.
,_ 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 re-
used. Only use original blades of
the specified type.
Trimmer head
IMPORTANT!
Always ensure the trimmer line is wound
tightly and evenly around the drum, other-
wise the machine will generate harmful
vibration.
• Only use the recommended cutting at-
tachments. See the section on "Technical
data".
Check the cutting attachment for damage
or cracks. A damaged cutting attachment
should always be replaced.
• Smaller machines generally require small
trimmer heads and vice versa. This is be-
cause when clearing using trimmer line
the engine must throw out the trimmer
line radially from the trimmer head and
overcome the resistance of the grass
being cleared.
• The length of the trimmer line is also im-
portant. A longer trimmer line requires
greater engine power than a shorter
trimmer line of the same diameter.
• Make sure that the cutter on the trimmer
guard is intact. This is used to cut the
trimmer line to the correct length.
• To increase the life of the trimmer line it
can be soaked in water for a couple of
days. This will make the line tougher so
that it lasts longer.

fire, explosion and inhaling fumes.
Fuel
CAUTION! The machine is equipped with a
two-stroke engine and must always be run
using a mixture of gasoline and two-stroke
engine oil. It is important to accurately mea-
sure 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
CAUTION! Always use high quality
unleaded gasoline.
• This engine is certified to operate on
unleaded gasoline.
• The lowest recommended octane rating is
87. If you run the engine on lower octane
rating than 87, "knocking" can occur. This
leads to an increased engine tempera-
ture, which can result in a serious engine
breakdown=
• When working at continuous high revs, a
higher octane rating is recommended.
Two-stroke oil
• For best results and performance, use
JONSERED two-stroke oil, which is
specially formulated for our two-stroke
engines. Mixture 1:50 (2%).
• To maximize the life of your trimmer, you
may choose to use a high quality syn-
thetic oil formulated for two-stroke

STARTING AND STOPPING
Check before starting
• Check the blade to ensure that no cracks
have formed at the bottom of the teeth or
by the centre hoIe. The most common rea-
son why cracks are formed is that sharp
corners have been formed at the bottom of
the teeth while sharpening or that the blade
has been used with dull teeth. Discard a
blade if cracks are found.
• Check that the support flange is not
cracked due to fatigue or due to being
tightened too much. Discard the support
flange if it is cracked.
• Ensure the locking nut has not lost its cap-
tive force. The nut tock should have a
locking force of at least 1.5 Nm. The tight-
ening torque of the locking nut should be
35-50 Nm.
Starting and stopping
WARNING: The complete clutch,
clutch cover, and shaft must be
fitted before the machine is started,
otherwise parts could come loose
and cause personal injury.
Always move the machine away
from the refueling area before
starting. Place the machine on a
flat surface. Ensure the cutting at-
tachment cannot come into contact
with any object.

WORKING TECHNIQUES
General working instructions
IMPORTANT!
This section describes the basic safety pre-
cautions for working with trimmers. If you
encounter a situation where you are uncer-
tain how to proceed you should ask an ex-
pert. Contact your servicing dealer.
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.
Basic safety rules
/ @OO
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 h_to contact with the cut-
ting attachment or loose objects that
are thrown out by the cutting attach-
ment.
• CAUTION! Do not use the machine
unless you are able to call for help in
the event of an accident.
2. Do not use the machine in bad weather,
such as dense fog, heavy rain, strong
wind, intense coid, etc. Working in bad
weather is tiring and often brings added
risks, such as icy ground, unpredictable
felling direction, etc.
3. Make sure you can move and stand safely.
Check the area around you for possible ob-
stacles (roots, rocks, branches, ditches, etc.)
in case you have to move suddenly. Take
great care when working on stoping ground.
The ABC of clearing
• Always use the correct equipment.
• 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.
• Always use sharp blades.
• Avoid stones.
WARNING: Neither the operator
of the machine nor anyone else
may attempt to remove the cut ma-
terial while the engine is running or
the cutting equipment is rotating,
as this can result in serious injury.
Stop the engine and cutting equip=
ment 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
burned if you touch it,
WARNING: Watch out for
thrown objects. Always wear ap=
proved eye protection. Never lean
over the cutting attachment guard.
Stones, rubbish, etc. can be thrown
up into the eyes causing blindness
or serious injury. Keep unautho-
rised persons at a distance. Chil-
dren, animals, onlookers and help-
ers should be kept outside the
safety zone of 50 feet (15 meters).
Stop the machine immediately if
anyone approaches. Never swing
the machine around without first
checking behind you to make sure
noone is within the safety zone.
WARNING: Sometimes branches
or grass get caught between the
guard and cutting attachment,
Always stop the engine before
c eaning.
4. Switch off the engine before moving to
another area. Fit the transport guard before
carrying or transporting the equipment any
distance.
5. Never put the machine down with the engine
running or while the cutting attachment is
rotating.
Basic working techniques
• Always slow the engine to idle speed after
each working operation. Long periods at
full throttle without any load on the engine
can lead to serious engine damage.
Working methods
WARNING: Avoid 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 kickback can occur if
you attempt to cut thick stems with
this area of the blade.

cutting
WORKING TECHNIQUES
• Before you start clearing, check the clear-
ing area, the type of terrain, the slope of
the ground, whether there are stones, hol-
lows etc.
• Start at whichever end of the area is easi-
est, and clear an open space from which
to work.
• Work systematically to and fro across the
area, clearing a width of around 12-15 feet
(4-5 meters) on each pass. This exploits
the full reach of the machine in both direc-
tions and gives the operator a convenient
and varied working area t_work in.
• Clear a strip around 250 feet (75 meters)
long. Move your fuel can as work prog-
resses.
• 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.
• If the blade is angled to the left when clear-
ing 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 re-
turn stroke and stand firmly again.
• Let the support cup rest lightly against the
ground. It is used to protect the blade from
hitting the ground.
• Reduce the risk of material wrapping
around the blade by following these in-
structions:
• Always work at full throttle.
• 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
QOO
_v -4
Grass clearing using a grass blade
• 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 teft-to-right is the return
stroke. Let the left-hand side of the blade
(between 8 and 12 o'clock) do the cutting.
• Hold the trimmer head just above the ground
at an angle, it is the end of the trimmer line
that does the work. Let the trimmer line work
at its own pace. Never press the trimmer
line into the area to be cut.
• The trimmer line 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.
• Reduce the risk of damaging pIants by
shortening the trimmer line to 4-5 inches
(10-12 cm) and reducing the engine speed.
• When trimming you should use tess than
full throttIe so that the trimmer line lasts
longer and to reduce the wear on the
trimmer head.
WORKING TECHNIQUES
Clearing Sweeping
@@0
• The clearing technique removes all un-
wanted vegetation. Keep the trimmer
head just above the ground and tilt it, Let
the end of the trimmer line strike the
ground around trees, posts, statues and
the like. CAUTION! This technique
increases the wear on the trimmer line.
• The trimmer line wears quieker and must
be fed forward mere often when werkh_g
agah_st stones, brick, eencrete, metal
fences, etc. than when coming into con-
tact with trees and wooden fenees.
Cutting
@@0
• The trimmer is ideal for cutting grass that
is difficult to reach using a normal lawn
mower, Keep the trimmer line 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 con-
staefly come into contact with the ground
during normal cutting. Constant contact
of this type can cause damage and wear
to the trimmer head.
@@@
• The fan effect of the rotating line can be
used for quick and easy clearing up.
Ho_d the trimmer line parallel to and
above the area to be swept and move
the tool to and fro.
/
I
\
• When cutting and sweeping you should
use full throttle to obtain the best results.
WARNING: Neither the operator
of the machine nor anyone else may
attempt to remove the cut material
while the engine is running or the
trimmer line is rotating, as this can
result in serious injury. Stop the
engine and trimmer head before you
remove material that has wound
around the drive 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 burned if you touch it.
i_ WARNING: Watch out for thrown
objects. Always wear eye protection.
Never lean over the cutting attach-
ment guard. Stones, rubbish, etc.
can be thrown up into the eyes
causing blindness or serious injury.
Keep unauthorized persons at a dis-
tance. Children, animals, onlookers
and helpers should be kept outside
the safety zone of 50 feet (15 me-
ters). Stop the machine immediately
if anyone approaches.
MAINTENANCE
The owner is responsible for the perfor-
mance of all required maintenance as
defined in the operator's manual.
WARNING:
nance could result in serious engine
[_JL. Improper mainte-
damage or in serious injury.
Carburetor
Your Jonsered product has been designed
and manufactured to specifications that re-
duce harmful emissions. After the engh_e
has used 8-10 tanks of fuet, the engh_e will
be run-in. To ensure that it continues to run
at peak performance and to minimize harm-
ful exhaust emissions after the run-in peri-
od, ask your servicing dealer to adjust your
carburetor.
WARNING: The complete clutch,
clutch cover, and shaft must be
fitted before the machine is started,
otherwise parts could 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 T-screw regulates the throttle setting
at idle speed. If the T-screw is turned
clockwise this gives a higher idle speed;
turning it counterclockwise gives a lower
idle speed.
Basic setting
• The basic carburetor setth_gs are ad-
justed during testing at the factory. Fine
adjustment should be carried out by a
skilled technician.
Fine adjustment of the idle speed-T
Adjust the idle speed using the idle adjust-
ment 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 counter-
clockwise until the cutting attachment stops.
The idle speed is correctly adjusted when
the engine will run smoothly in every posi-
tion. The idle speed should also be well
below the speed at which the cutting attach-
ment starts to rotate.

attachment stops, contact your ser-
vicing dealer, Do not use the ma-
chine until it has been correctly ad-
justed or repaired,
Unit/Maintenance Safety
Disconnect the spark plug before perform-
ing maintenance, except carburetor adjust-
ments.
Muffler
CAUTION! Muffler is fitted with a catalytic
converter designed to reduce harmful ex-
WARNING: The cutting attach-
ment may be spinning during carbu-
retor adjustments. Wear your protec-
tive equipment and observe all safe-
ty instructions. Be sure the cutting
attachment stops turning when the
engine idles, When the unit is turned
off, make sure the cutting attach-
ments has stopped before the unit is
set down.
CAUTION! if the cutting attachment rotates
when the engine is idling the idle adjustment
screw T should be turned counterclockwise
until the cutting attachment stops.
Rec. idle speed:
See "Technical data" section.
Recommended max. speed:
See "Technical data" section.
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 com-
bustible material
Mufflers are equipped with a special spark
arrestor mesh. The mesh should be
checked and, if necessary, cleaned by a
servicing dealer. If the mesh is damaged,
it should be replaced.
2O
MAINTENANCE
If the mesh is frequently blocked, this can
be a sign that the performance of the cata-
lytic converter is impaired. Contact your
servicing dealer to inspect the muffler. A
blocked mesh wilt cause the machh_e to
overheat and result in damage to the cylin-
der and piston.
Muffler bolts
I_ Spark arrestor mesh
CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.
catalytic converters get very hot
during use and remain so for some
time after stopping, This also ap-
plies at idle speed, Contact can re-
I_ib ARNING: Mufflers fitted with
sult in burns to the skin. Remember
the risk of fire!
_lb WARNING: The inside of the
muffler contain chemicals that may
be carcinogenic, Avoid contact with
these elements in the event of a
damaged muffler,
_lb WARNING: Bear in mind that:
Engine exhaust fumes contain car-
bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any-
where that is poorly ventilated.
The exhaust fumes from the engine
are hot and may contain sparks
which can start a fire. Never start
the machine indoors or near com-
bustible material!
Spark plug
The spark plug condition is h_fluenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or in-
correct type of oil).
• A dirty air filter.
These factors cause deposits on the spark
plug electrodes, which may result in operat-
ing 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 0.024 inch (0.6
mm). The spark plug should be replaced
after about a month in operation or earlier if
necessary. 0.024 inch (0.6 mm)
CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder,
Air filter
The air filter must be regularly cleaned to
remove dust and dirt in order to avoid:
Carburetor malfunctions
Starting problems
Loss of engine power
Unnecessary wear to engine parts
Excessive fuel consumption
I
jfJ
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,
Rinse thoroughly. 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.
21
MAINTENANCE
Bevel gear
The bevel gear is filled with the right quan-
tity of grease at the factory. However, be-
fore using the machine you should check
that the bevel gear is filled three-quarters
full with grease. Use JONSERED special
grease.
The grease in the bevel gear does not nor-
mally need to be changed except if repairs
are carried out.
Sharpening grass cutters and
grass blades
WARNING: Always stop the en-
gine before doing any work on the
cutting attachment. This continues
to rotate even after the throttle has
been released. Ensure that the cut-
ting attachment has stopped com-
pletely and disconnect the HT lead
from the spark plug before you start
to work on it.
• 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
batance of the blade.
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 re-
used. Only use original blades of the
specified type.
