SAFETY INSTR UCTIONS
ersonal protective equipment
IMPORTANT! Whenever you use a clearing saw,
brushcutter or trimmer you must wear personal protective
equipment that is approved by the authorities. Personal
protective equipment does not eliminate the risk of
accidents, but it can reduce the effects of an injury in the
event of an accident. Ask your dealer for help when
choosing protective equipment.
ARNING! Listen out for warning signals or
shouts when you are wearing hearing
!
protection. Always remove your hearing
protection as soon as the engine stops.
GLO VES
Gloves should be worn when necessary, e.g., when fitting
cutting attachments.
FIRST AID KIT
Always have a first aid kit nearby.

purpose, and how checks and maintenance should be carried
out to ensure that it operates correctly. See the ”What is
what?” section to locate where this equipment is positioned
on your machine.
The life span of the machine can be reduced and the risk of
accidents can increase if machine maintenance is not carried
out correctly and if service and/or repairs are not carried out
professionally. If you need further information please contact
your nearest service workshop.
!
′′
s safety equipment
ARNING! Never use a machine that has
faulty safety equipment! Carry out the
inspection, maintenance and service
routines listed in this section.
HEARING PROTECTION
Wear hearing protection that provides adequate noise reduction.
EYE PROTECTION
Always wear approved eye protection. If you use a visor then
you must also wear approved protective goggles. Approved
protective goggles must comply with standard ANSI Z87.1 in
the USA or EN 166 in EU countries. Visors must comply with
standard EN 1731.
BOOTS
Wear sturdy, non-slip boots.
Thr ottle lock
The throttle loc k 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 lock
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.
Stop s witch
Use the stop s witch to switch off the engine.
CLOTHING
Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants. Do not wear jewellery, shorts sandals or go barefoot. Secure hair so it is above shoulder level.

ARNING! 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.
Vibration damping system
our 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.
The machine ′ s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine ′ s handle unit.
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.
ARNING! 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!
ARNING! The inside of the muffler contain
chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a
damaged muffler.
ARNING! Bear in mind that:
Engine exhaust fumes contain carbon
!
monoxide, which can cause carbon
monoxide poisoning. For this reason you
should not start or run the machine indoors,
or anywhere that is poorly ventilated.
ARNING! 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.
These 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.
Muffl er
The m uffler 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.
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!
Cutting equipment
ass blades and grass cutters are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.
Loc king nut
A loc king nut is used to secure some types of cutting attachment.
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.

attachment you are using. See chapter on Technical data.
• Check that the throttle control and throttle lock 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.
Vibration damping system
Regularly check the vibration damping units for cracks or
deformation.
• Check that the vibration damping element is undamaged
and securely attached.

Never use a machine that has a faulty muffler.
English
SAFETY INSTRUCTIONS
• Regularly check that the muffler is securely attached to
the machine.
• If the muffler on your machine is fitted with a spark arrestor
mesh then it should be cleaned regularly. A blocked mesh
causes the engine to overheat, which can lead to serious
damage. Never use a muffler with a defective spark
arrestor mesh.
Cutting equipment
This section describes how to choose and maintain your cutting equipment in order to:
• Reduce the risk of kickback.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
General rules
1 Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Locking nut
• 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.)
• Tighten the nut using the socket spanner. 35-50 Nm (3.55 kpm).
CAUTION! 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.
WARNING! Never use a machine with faulty
safety equipment. The machine’s safety
!
equipment must be checked and maintained
as described in this section. If your machine
fails any of these checks contact your
service agent to get it repaired.
2 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.
3 Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.

SAFETY INSTRUCTIONS
Cutting equipment
IMPORTANT!
This section describes how to choose and maintain your cutting equipment in order to:
Reduce the risk of kickback.
Obtain maximum cutting performance.
Extend the life of cutting equipment.
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.
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
!
blade increases the risk of kickback.
• 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.
IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
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.
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.
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.

WARNING! Using an incorrect cutting
attachment or an incorrectly filed blade can
!
increase the risk of accidents.
Starting
• Place the machine on the ground, ensure the cutting
attachment is clear of twigs and stones. Hold the body of
the machine on the ground using your left hand
(CAUTION! Not with your foot). Then grip the starter
handle with your right hand and pull the starter cord.
Fuel safety
• Always use a fuel container with an anti-spill valve.
• Never refuel the machine while the engine is running.
Always stop the engine and let it cool for a few minutes
before refuelling.
• Make sure there is plenty of ventilation when refuelling or
mixing fuel (gasoline and 2-stroke oil).
• Move the machine at least 3 m from the refuelling point
before starting it.
• Never start the machine:
1 If you have spilt fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 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.
4 Avoid all skin contact with fuel. Fuel is a skin irritant
and may even cause skin changes.
WARNING! When the engine is started with
the choke in either the choke or start throttle
!
positions the cutting attachment will start to
rotate immediately.
• The complete clutch cover and shaft must be fitted before
the machine is started, otherwise the clutch can come
loose and cause personal injury.
• Never start the machine indoors. Exhaust fumes can be
dangerous if inhaled.
• Observe your surroundings and make sure that there is no
risk of people or animals coming into contact with the
cutting equipment.
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.
• 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.
English – 9
SAFETY INSTRUCTIONS
• The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and
!
inhaling fumes.
General working instructions
IMPORTANT!
This section describes the basic safety precautions for working with clearing saws 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.
Basic safety rules
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.
Terms
• Use a grass cutter or grass blade for clearing grass.
• Use a trimmer head or plastic blades for lighter clearing
work, for example along verges or around trees.
WARNING! Sometimes branches or grass
get caught between the guard and cutting
!
attachment. Always stop the engine before
cleaning.
Grass clearing using a grass blade
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 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 can lead to dangerous
conditions, e.g. slippery surfaces.
3 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.
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
unless you have it in clear sight.
• 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.
• 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.
• 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 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.
