SAFETY INSTRUCTIONS
Personal 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.
WARNING! Listen out for warning signals or
shouts when you are wearing hearing
!
protection. Always remove your hearing
protection as soon as the engine stops.
HELMET
A helmet should be worn if the trees being cleared are taller
than 2 m.
HEARING PROTECTION
Wear hearing protection that provides adequate noise
reduction.
FIRST AID KIT
Always have a first aid kit nearby.

s safety equipment
WARNING! Never use a machine that has
faulty safety equipment! Carry out the
inspection, maintenance and service
routines listed in this section.
Throttle lock
The throttle lock 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.
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.
GLOVES
Gloves should be worn when necessary, e.g., when fitting
cutting attachments.
BOOTS
Wear sturdy, non-slip boots.
Stop switch
Use the stop switch to switch off the engine.
Cutting attachment guard
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.
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.

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.
SAFETY INSTRUCTIONS
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
Using incorrectly wound cord or a blunt or incorrect cutting
attachment (wrong type or incorrectly filed, see instructions
under the heading Filing the blade) 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.
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.
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 clearing saw.
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.
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.
WARNING! 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.
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
Saw blades are intended for cutting fibrous types of wood.
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.
Grass blades and grass cutters are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.

risk of accidents.
• 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 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.
3 Maintain the correct blade setting! Follow our instructions
and use the recommended blade setting tool. An
incorrectly set blade increases the risk of jamming and
kickback.
4 Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.

SAFETY INSTRUCTIONS
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.
Filing the saw blade
• See the cutting attachment packaging for correct
sharpening instructions.
• A correctly filed blade is essential for working efficiently
and to avoid unnecessary wear to the blade and clearing
saw.
• 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.
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.
Maintain the correct blade setting! Follow our instructions
and use the recommended file gauge.
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
!
blade increases the risk of kickback.
• Adjust the blade setting. This should be 1 mm.
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.

SAFETY INSTRUCTIONS
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. 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.
General safety precautions
IMPORTANT!
The machine is only designed for trimming grass, grass
clearing and/or forestry clearing.

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
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 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 obstacles (roots, rocks, branches,
ditches, etc.) in case you have to move suddenly. Take
great care when working on sloping ground.
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.

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.
SAFETY INSTRUCTIONS
Adjusting the harness and clearing saw
WARNING! When using a clearing saw it
must always be hooked securely to the
!
harness. Otherwise you will be unable to
control the clearing saw safely and this can
result in injury to yourself or others. Never
use a harness with a defective quick release.
Always use a double harness that
distributes the load across both shoulders.
Safety release
At the front is an easily accessible, quick release. Use this if
the engine catches fire or in any other emergency situation
that requires you to free yourself from the machine and
harness.
Correct balance
Let the cutting attachment rest lightly on the ground. If you
use a saw blade it should balance about 10 cm above the
ground to prevent contact with stones and the like. Adjust the
position of the support hook to balance the clearing saw
correctly.
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 saw blade for cutting woody growth with thin stems.
Spreading the load on your shoulders
A well-adjusted harness and machine makes work much
easier. Adjust the harness for the best working position.
Tension the side straps so that the weight is evenly distributed
across both shoulders.
Correct height
Adjust the shoulder strap so that the cutting attachment is
parallel to the ground.
• 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.

SAFETY INSTRUCTIONS
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! 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 kickback can occur if you
attempt to cut thick stems with this area of
the blade.
Working methods
• Before you start clearing, check the clearing area, the type
of terrain, the slope of the ground, whether there are
stones, hollows etc.
• 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.
• The strip should be planned so that you avoid going over
ditches or other obstacles on the ground.
Brush cutting with a saw blade
• Cut through thin stems and brush. Work with a sawing
movement, swinging sideways.
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 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.
• Avoid cutting with the area of the blade between the 12
o’clock and 3 o’clock positions.
WARNING! Neither the operator of the
machine nor anyone else may attempt to
!
remove the cut material while the engine is
running or the blade is rotating, as this can
result in serious injury.
Stop the engine and blade 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 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 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.
