MPORTANT INFORMATION
• A clearing saw, brushcutter or trimmer used
incorrectly or carelessly can become a
dangerous tool, that can cause serious or fatal
injury to the operator or others. It is extremely
important that you read and understand the
content of this manual.
• When using a trimmer, personal 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!
!
GLOVES
Gloves should be worn
when necessary, e.g., when
assembling cutting
equipment.
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.
BOOTS
Use anti-slip and stable
boots.
CLOTHING
Wear clothes made of a
strong fabric and avoid
loose clothing that can
catch on shrubs and
branches. Always wear
heavy, long pants. Do not
wear jewelry, short pants,
sandals or go barefoot.
Secure hair so it is above
shoulder level.
FIRST AID KIT
A first aid kit should be
carried by operators of
clearing saws, brushcutters
or trimmers.
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
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
4. Vibration
damping system
Your machine is equipped
with a vibration damping
system, which is designed
to give as vibration-free
and comfortable use as
possible.
Use of incorrectly wound
cord or incorrect cutting
equipment 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.
5. 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!
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.
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!
WARNING!
Bear in mind that exhaust fumes:
• contain carbon monoxide, which can
cause carbon monoxide poisoning.
Therefore never start or run the machine
indoors.
• are hot and can contain sparks that can
cause fires. Never start the machine
indoors or close to inflammable material.
6. Cutting
equipment
The trimmer head is
intended for trimming
grass.
7. Locking nut
A locking nut is used to
secure some types of cutting
equipment on the output
shaft.

SAFETY INSTRUCTIONS
6. Cutting equipment
The section describes how through correct maintenance and
through using the right type of cutting equipment you can:
• Obtain maximum clearing capacity.
• Increase the service life of the cutting equipment.
Two basic rules:
1)Only use the cutting
and guard equipment
we recommend! See
chapter “Technical
data“.
2)Check the cutting
equipment with regard
to damage and crack
formation. Damaged
cutting equipment
should always be
replaced.
7. Locking nut
Cutting equipment
IMPORTANT INFORMATION
The section describes how through correct
maintenance and through using the right type of
cutting equipment you can 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“.
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“.
• 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).
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.
• 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.
• 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 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.
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.
• 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.
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.
Basic working 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.
WARNING!
!
Grass trimming
using the trimmer
head and plastic
knifes
• Hold the trimmer head
just above the ground at
an angle. It is the end of
the cord that carries out
the work. Let the cord
work at its own pace. Do
not press the cord into the
area to be cut.
• The cord 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 plants by
shortening the cord to 1012 cm and reducing the
engine speed.
Sometimes branches, grass or wood can
get caught between the guard and cutting
equipment. Always stop the engine when
cleaning.
4. The engine should be switched off before moving. When
moving over longer distances and transporting the transport
guard should be used.
5. Never put the machine down with the engine running
unless you have good sight of it.
6. Do not over-reach
7. Keep Cutting attachment below waist level.
