• When using a clearing saw, brushcutter or
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.
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.
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.
B

SAFETY INSTRUCTIONS
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 antivibration system reduces
the transfer of vibrations
between the engine unit/
cutting equipment and the
machine’s handle system.
The engine body including
the cutting equipment is
suspended in the handle
system via a vibration
element.
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, “tic kling“, “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.
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!
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.
7. Cutting
equipment
1) Clearing blades are

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.
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).
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.
4)Check the cutting
equipment with regard
to damage and crack
formation. Damaged
cutting equipment
should always be
replaced.
• 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

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
• 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 teeth 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.
WARNING!
Incorrect cutting equipment or an
!
incorrectly sharpened blade increases
the risk of kickback.
Sharpening the
clearing blade
• See the cutting
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.
• 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.
“Technical data“.
Filing 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.
• 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.
