SAFETY INSTRUCTIONS
Personal protective equipment
IMPORTANT INFORMATION
• Incorrect or careless use of a clearing saw,
brushcutter or trimmer can turn it into a dangerous
tool that can cause serious or even fatal injury to
the operator or others. It is extremely important
that you read and understand the content of this
manual.
• When using a clearing saw, brushcutter or trimmer,
protective equipment approved by the appropriate
authorities must be used. Personal protective
equipment does not eliminate the risk of
accidents, however, it can reduce the effects of an
injury in the event of an accident. Ask your dealer
for help when choosing protective equipment.
WARNING!
!
HELMET
A helmet should be worn if
trees to be cleared are higher
than 2 metres.
EAR PROTECTION
Ear protection offering
sufficient dampening effect
should be used.
EYE PROTECTION
Blows from branches or
objects thrown by the
rotating cutting equipment
can damage the eyes.
Remove your hearing protection as soon as
you stop the engine, so that you can hear
any noises or warning signals.
The machine‘s safety equipment
This section describes the machine‘s safety equipment, its
function and how checks and maintenance are carried out to
ensure that it operates correctly. (See the chapter “What is
what“ to locate where this equipment is positioned on your
machine.)
WARNING!
!
Never use a machine with defective safety
equipment. Follow the control,
maintenance and service instructions
described in this section.
1. Throttle trigger
lock
A
The throttle trigger lock is
designed to prevent the
throttle from accidentally
being engaged. When the
trigger lock (A) is pressed
into the handle (= when you
hold the handle) the throttle
(B) is released. When the
grip on the handle is
released the throttle and the
throttle trigger lock return
to their original positions.
This takes place via two
independent return spring
systems. This means that the
throttle is automatically
locked in its “idling“
position.

SAFETY INSTRUCTIONS
2. Stop switch
The stop switch should be
used to stop the engine.
4. Anti-vibration
system
Your machine is equipped
with an anti-vibration system
that has been designed to
give as vibration-free and
comfortable usage as
possible.
The use of incorrectly
wound cord or blunt,
incorrect cutting equipment
(incorrect type or incorrectly
sharpened, see section “Filing
the blade”) increases the level
of vibration.
The machine’s vibration
damping system reduces the
transfer of vibrations
between the engine unit/
cutting equipment and the
machine’s handle unit.
3. Cutting
attachment guard
This guard is intended to
prevent objects from being
thrown towards the operator
and to protect the operator
from unintentionel contact
with the cutting attachment.
WARNING!
Do not attach any blade to the unit without
!
proper installation of all required parts.
Failure to use the proper parts can cause
the blade to fly off and seriously injure the
operator and/or bystanders.
Under no circumstances may the cutting
equipment be used without an approved
guard fitted. See the chapter
data”
. If the wrong guard or a defective
guard is fitted this can cause serious
personal injury.
“Technical
WARNING!
Over exposure to vibrations can result in
!
blood-vessel or nerve injury to persons
suffering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are “numbness“, lack of
feeling, “tickling“, “pricking“, “pain“, lack of
or a reduction in normal strength, changes
in the colour of the skin or its surfaces.
These symptoms normally appear in the
fingers, hands or wrists.
5. Quick-release
There is an easily accessible,
quick-release catch fitted to
the chest as a safety
precaution in the event of a
fire in the engine or for any
other situation that requires
you to free yourself from the
machine and harness. See the
section “Adjusting the harness
and clearing saw“.
English – 5
SAFETY INSTRUCTIONS
6. Muffler
The muffler is designed to
give the lowest possible noise
level and to direct the
engine‘s exhaust fumes away
from the operator. Muffler
fitted with catalytic
converter is also designed to
reduce harmful exhaust
components.
In countries that have a
warm and dry climate the
risk of fire is obvious. We
have therefore fitted certain
mufflers with a spark arrest
screen. Make sure that your
muffler is fitted with this
kind of screen.
It is extremely important
that the instructions for
checking, maintaining and
servicing the muffler are
followed. (See the section
“Control, maintenance and
service of the machine‘s safety
equipment“.)
WARNING!
!
Mufflers fitted with catalytic converters
become extremely hot during use and after
stopping. This also applies at idling speeds.
Contact can result in burns to the skin. Be
observant to the risk of fire!
7. Cutting
equipment
1) Clearing blades are
intended for cutting wood.
2) Grass blades are
intended for brush cutting.
3) The trimmer head is
intended for trimming

SAFETY INSTRUCTIONS
6. Cutting equipment
This section describes how through correct maintenance and
through using the right type of cutting equipment you can:
• Reduce the machine‘s tendency to kickback
• Obtain maximum cutting capacity.
• Increase the service life of the cutting equipment.
Four basic rules:
1)Only use the cutting
and guard equipment
we recommend! See
chapter “Technical
data“.
2)Keep the blade‘s teeth
well and correctly
sharpened! Follow our
instructions and use the
recommended filing
gauge. An incorrectly
sharpened or damaged
blade increases the risk
of an accident.
3)Keep the correct setting.
Follow our instructions
and use the
recommended setting
tool. An incorrectly set
blade increases the risk
of jamming and
kickback.
7. Quick-release
• Check that the harness
straps are correctly
positioned. When the
harness and machine are
adjusted, check the harness‘
safety release catch to
ensure it works correctly.
8. Locking nut
• Protect your hand from
injury when assembling,
use the blade guard as
protection when tightening
with a socket spanner.
Tighten the nut by turning
against the direction of
rotation. Loosen the nut by
turning in the direction of
rotation. (NOTE! the nut
has a left-hand thread).
• Tighten the nut using a
socket spanner, 35 - 50
Nm (3.5 - 5 kpm).
4)Check the cutting
equipment with regard
to damage and crack
formation. Damaged
cutting equipment
should always be
replaced.
NOTE!
The locking nut‘s nylon lock
must not be so worn that it
can be turned by hand. The
lock shall hold 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 defective safety
!
equipment. The safety equipment should be
maintained as described in this section. If
your machine does not meet any of these
controls you should contact your service
workshop.

SAFETY INSTRUCTIONS
Cutting equipment
IMPORTANT INFORMATION
The section describes how through correct maintenance and through using the right type of cutting
equipment you can reduce the machine‘s tendency to
kickback, obtain maximum clearing capacity and
increase the service life of the cutting equipment.
• Only use the cutting and guard equipment we
recommend! See chapter “Technical data“.
• Refer to the instructions for the cutting
equipment for the correct winding of cord
and for the selection of the right cord diameter.
• Keep the blade’s teeht well and correctly
sharpened! Follow our recommendations. Also
refer to the instructions on the blade packaging.
• Maintain the correct setting. Follow our instructions and use the recommended filing gauge.

equipment’s packaging for
correct filing instructions.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing saw.
incorrectly sharpened blade increases
the risk of kickback.
Sharpening the
grass blade
• See the cutting
equipment’s packaging for
correct filing instructions.
• The blades are sharpened
using a single cut flat file.
• Sharpen all edges equally
to maintain the balance of
the blade.
Trimmer head
• Only use a trimmer head
and trimmer cord that is
recommended. 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
cutting equipment we
recommend! See chapter
“Technical data“.
• Generally smaller machines require a small trimmer head
and vice versa. This is because when clearing using a cord
the engine must throw out the cord radially from the
trimmer head and also meet resistance from the grass being
cleared.
• Make sure that the blade is
well supported when you
use the file. Use a 5,5 mm
round file with a file
holder.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right and
the intermediate tooth to
the left. When the blade
has been heavily pitted by
stones the upper side of
the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
Dressing the top side must
be carried out equally for
all teeth.
• Adjust the setting. This
should be 1 mm.
• 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 the knife positioned 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 few days. This will make the line tougher and it will keep
longer.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly
and evenly around the drum, otherwise harmful
vibrations will occur.
WARNING!
!
Always stop the engine before starting
work on any part of the cutting equipment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting equipment has stopped completely
and remove the cable from the spark plug
before you start to work on it.

SAFETY INSTRUCTIONS
General working instructions
IMPORTANT INFORMATION
• This section takes up the basic safety precautions
for working with the clearing saw and trimmer.
• 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
clearing, brush cutting and grass trimming before
using the machine.
Basic safety precautions
1.Observe your surroundings:
• To ensure that people, animals or other things cannot affect
your control of the machine.
• To ensure that the above mentioned do not come into
contact with the cutting equipment or objects that can be
thrown by the cutting equipment.
4.Take great care when
cutting a tree that is subject
to tension. A tree that is
under tension can spring
back to its original position
both before and after being
cut. Incorrect positioning
on your behalf or when
positioning the cut can
result in the tree hitting you
or the machine so that you
lose control. Both situations
can cause serious personal
injury.
5.The engine should be
switched off before moving.
When moving over longer
distances and transporting
the transport guard should
be used.
6.Never put the machine
down with the engine
running unless you have
good sight of it.
• NOTE! Never use a machine without the possibility of
calling for help in the event of an accident.
2.Avoid usage in
unfavourable weather
conditions. For example,
thick fog, heavy rain,
strong winds or extreme
cold, etc. To work in bad
weather conditions is
tiring and can create
dangerous circumstances,
e.g. slippery surfaces,
affect a tree‘s direction of
fall, etc.
3.Make sure you can walk
and stand safely. Look out
for any obstacles with
unexpected movement
(roots, stones, branches,
pits, ditches, etc.). Take
great care when working
on sloping ground.

SAFETY INSTRUCTIONS
Adjusting the harness and clearing saw
WARNING!
When working with the clearing saw it
!
Quick release
On the front is an easily
accessible, quick release
catch. Use this if the engine
should catch fire or in any
other emergency situation
when you quickly need to
take off the harness and
machine.
Even load on the
shoulders
A well-adjusted harness and
clearing saw significantly
facilitates working. Adjust
the harness for the best
working position. Tension
the side straps so that the
weight is evenly distributed
across the shoulders.
should always be hooked in the harness. If
this is not done, you cannot control the
clearing saw safely and this can result in
injury to yourself or someone else. Never
use a harness with a defective quick
release catch.
Basic clearing techniques
• Always drop to idling speed after each working operation.
Longer periods running at full throttle without loading the
engine (that is without resistance, which the engine feels
from the cutting equipment when trimming) can lead to
serious engine damage.
Designations
• Forestry clearing is a
general term for cutting
small trees where each
stem is cut individually.
A saw blade is used.
• Brush cutting is a general
term for clearing grass.
Grass blades are used for
this purpose.
• Grass trimming is a
general term for light
clearing, e.g. around
edges or around trees. A
trimmer head or plastic
blade is used.
Correct height
1) Forestry clearing
Adjust the carrier strap so
that the suspension hook
comes approximately 10
cm under the hip. The
blade should be angled
forward a little.
2)Grass clearing
The suspension hook
should hang
approximately 20 cm
under the hip so that the
blade is parallel to the
ground.
Correct balance
1)Forestry clearing
Move the suspension eye
forwards or backwards. If
the blade is balanced a 1020 cm above the ground it
is easier to avoid stones.
!
WARNING!
Sometimes branches, grass or wood can
get caught between the guard and cutting
equipment. Always stop the engine when
cleaning.
2)Grass clearing
Let the blade balance at a
comfortable clearing
height, i.e. close to the
ground.
English – 13
SAFETY INSTRUCTIONS
Clearing‘s ABC
A. Always use the correct equipment.
B. Always have well adjusted equipment.
C. Follow the safety instructions.
D. Organise the work well.
E. Always use full throttle when applying the blade.
F. Always use a sharp blade.
G. Avoid stones.
H. Guide the direction of fall (use the wind).
WARNING!
!
Working methods
• Before you start clearing, check the clearing area, its
condition, slopes, if there are stones, pits, etc.
• Thereafter start at the end which is easiest, and make a good
start to the clearing.
Avoid cutting in the cutting region between
12 and 3 o‘clock on the blade. Kickback can
occur due to the blade‘s rotation speed in
this area of the blade when applied on thick
stems.
Forestry clearing
using a saw blade
• When applying the blade
to heavier stems the risk of
kickback increases. You
should therefore avoid
applying the blade on the
cutting area between 12
and 3 o‘clock.
• To fell to the left, the
lower section of the tree
should carry to the right.
Angle the blade and move
it with a resolute
movement diagonally
down to the right. At the
same time press against the
stem using the blade
guard. Apply the blade on
the area between 3-5
o‘clock. Use full throttle
when applying the blade.
• Work systematically to
and from and across the
area. Each stroke should
encompass a working
area of 4-5 metres. This
then utilises the full
working area of the
machine in both
directions and provides
the operator with an easy
and variable working
area to work through.
• The length of the
pathway should be
approx. 75 m. Move the
fuelling station as work
progresses.
• On sloping ground the
pathway should run
parallel to the slope. It is
far easier to work along a
slope then up and down
a slope.
• To fell to the right, the
lower section of the tree
should carry to the left.
Angle the blade and move
it with a resolute
movement diagonally up
to the left. Apply the blade
on the area between 3 and
5 o‘clock so that the
blade‘s direction of
rotation carries the lower
section of the tree to the
left.
• The pathway should be
planned so that you
avoid going over ditches
or other obstacles. Also
adapt the pathway to the
wind conditions so that
the cleared stems fall on
the part of the stand that
has been cleared.
14 – English
• To fell a tree forwards the
lower section of the tree
should be drawn
backwards. Draw the blade
backwards with a quick
and resolute movement.
