GENERAL SAFETY PRECA UTIONS
8 – English
Thr ottle trigger lockout
The throttle loc kout is designed to prevent accidental
operation of the throttle control. When you press the lock
(A) (i.e. when you grasp the handle) it releases the throttle
control (B). When you release the handle the throttle
control and the throttle lockout both move back to their
original positions. This movement is controlled by two
independent return springs.This arrangement means that
the throttle control is automatically locked at the idle
setting.
Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
Press the throttle lockout and make sure it returns to its
original position when you release it.
Check that the throttle trigger and throttle lockout move
freely and that the return springs work properly.
See instructions under the heading Start. Start the
machine and apply full throttle. Release the throttle and
check that the cutting attachment stops and remains at a
standstill. If the cutting attachment rotates with the throttle
in the idle position then the carburettor idle setting must
be checked. See instructions under the heading
Maintenance.
Stop s witch
Use the stop s witch to switch off the engine.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Cutting attac hment guard
This guard is intended to pre vent 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 chapter on Technical data.
!
WARNING! Never use a cutting
attachment without an approved guard.
See the chapter on Technical data. If an
incorrect or faulty guard is fitted this can
cause serious personal injury.

GENERAL SAFETY PRECAUTIONS
English – 9
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.
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
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
under the heading Adjusting the harness and brush
cutter. Certain harnesses also have a quick release fitted
to the support hook.
Check that the harness straps are correctly positioned.
Once the harness and machine have been adjusted,
check that the harness quick release works correctly.
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.
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.
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.
Never use a machine that has a faulty muffler.
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! 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.

GENERAL SAFETY PRECAUTIONS
10 – English
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
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
should operate the socket spanner when loosening or
tightening the nut.
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
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.
Cutting equipment
Saw blades are intended for cutting fibrous types of wood.
Grass blades and grass knifes are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.
!
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!
!
WARNING! The inside of the muffler
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
IMPORTANT! 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!
IMPORTANT!
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Refer to the instructions for the cutting attachment to
check the correct way to load the cord and the correct
cord diameter.
Keep the teeth of the blade correctly sharpened! Follow
our recommendations. Also refer 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 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
spark plug cap before you start to work
on it.
!
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.

GENERAL SAFETY PRECAUTIONS
English – 11
General rules
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Keep the teeth of the blade correctly sharpened! Follow
our instructions and use the recommended file gauge. An
incorrectly sharpened or damaged blade increases the
risk of accidents.
Keep the correct setting on the saw blade! Follow our
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.
Sharpening grass knifes and grass
blades
• See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and knifes
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 reused. Only use original blades
of the specified type.

GENERAL SAFETY PRECAUTIONS
12 – English
Sharpening the saw blade
• See the cutting attachment packaging for correct
sharpening instructions.
A correctly sharpened blade is essential for working
efficiently and to avoid unnecessary wear to the blade and
brush cutter.
• Make sure that the blade is well supported when you
file it. Use a 5.5 mm round file with a file holder.
• 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.
Adjust the blade setting. This should be 1 mm.
Trimmer head
• 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 before use. This will make
the cord tougher so that it lasts longer.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.

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.
Fuel
CAUTION! The machine is equipped with a two-stroke
engine and must always be 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.
Petrol
CAUTION! 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
two-stroke engine oil, which is specially formulated for
our air-cooled 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.
• A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.
• 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.
!
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
!
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.

FUEL HANDLING
English – 19
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.
Fueling
•If you have spilled fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
• 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.
!
WARNING! The catalytic converter
muffler gets very hot during and after
use. This also applies during idling. Be
aware of the fire hazard, especially when
working near flammable substances and/
or vapours.
!
WARNING! Taking the following
precautions, will lessen the risk of fire:
Mix and pour fuel outdoors, where there
are no sparks or flames.
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 and source before
starting.

STARTING AND STOPPING
20 – English
Check before starting
•Check the blade to ensure that no cracks have formed
at the bottom of the teeth or by the centre hole. The
most common reason 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 captive force.
The nut lock should have a locking force of at least 1.5
Nm.The tightening torque of the locking nut should be
35-50 Nm.
• Check that the blade guard is not damaged or
cracked. Replace the blade guard if it is exposed to
impact or is cracked.
Check that the trimmer head and trimmer guard are not
damaged or cracked. Replace the trimmer head or
trimmer guard if they have been exposed to impact or are
cracked.
• Never use the machine without a guard nor with a
defective guard.
• All covers must be correctly fitted and undamaged
before you start the machine.
Starting and stopping
Cold engine
Ignition: Set the stop switch to the start position.
Choke: Set the choke control (A) in the choke position.
Primer bulb: Press the air purge diaphragm (B)
repeatedly until fuel begins to fill the diaphragm. The
diaphragm need not be completely filled.
!
WARNING! The complete clutch cover
and shaft must be fitted before the
machine is started, otherwise the clutch
can come loose and cause personal
injury.
Always move the machine away from the
refuelling area and source before
starting. Place the machine on a flat
surface. Ensure the cutting attachment
cannot come into contact with any
object.
Make sure no unauthorised persons are
in the working area. Otherwise there is a
risk of serious personal injury.The safety
distance is 15 meters.
