IMPOR TANT!
A clearing saw, brushcutter or trimmer can be dangerous if
used incorrectly or carelessly, and can cause serious or
fatal injury to the operator or others. It is extremely
important that you read and understand the contents of this
operator’s manual.
You must use approved personal protective equipment
whenever you use the machine. Personal protective
equipment cannot eliminate the risk of injury but it will
reduce the degree of injury if an accident does happen. Ask
your dealer for help in choosing the right 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.
HELMET

Cutting attac hment guard
This guard is intended to pre vent loose objects from being
thrown towards the operator. The guard also protects the
operator from accidental contact with the cutting attachment.
Check that the guard is undamaged and not cracked. Replace
the guard if it has been exposed to impact or is cracked.
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.
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.
Check that the vibration damping element is undamaged and
securely attached.
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.
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.
Vibration damping system
our machine is equipped with a vibration damping system
that is designed to reduce vibration and make operation
easier.
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration. See instructions
under the heading Cutting equipment.
The machine ′ s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine ′ s handle unit.
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 screen. Check whether the muffler on your
machine is fitted with this kind of screen.
For mufflers it is very important that you follow the instructions
on checking, maintaining and servicing your machine.
Never use a machine that has a faulty muffler.
Regularly check the vibration damping units for cracks or
deformation.
–
English
Regularly check that the muffler is securely attached to the
machine.
GENERAL SAFETY PRECAUTIONS
If the muffler on your machine is fitted with a spark arrestor
screen this must be cleaned regularly. A blocked screen will
cause the engine to overheat and may lead to serious
damage.
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:
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!
Locking nut
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
• Reduce the risk of blade thrust.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
IMPORTANT!
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! 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.
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
!
blade increases the risk of blade thrust.
A locking nut is used to secure some types of cutting
attachment.
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.) When
loosening and tightening the saw blade nut, there is a risk of
injury from the teeth of the saw blade. You should therefore
always ensure that your hand is shielded by the blade guard
when doing this. Always use a socket spanner with a shaft
that is long enough to allow this. The arrow in the diagram
shows the area where you should operate the socket spanner
when loosening or tightening the nut.
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.
Cutting equipment
Grass blades and grass cutters are intended for cutting
coarse grass.
A trimmer head is intended for trimming grass.

GENERAL SAFETY PRECAUTIONS
General rules
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
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.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
Sharpening grass cutters and grass blades
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly
around the drum, otherwise the machine will generate
harmful vibration.
• 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.
• 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.
WARNING! Always discard a blade that is
bent, twisted, cracked, broken or damaged
!
in any other way. Never attempt to straighten
a twisted blade so that it can be reused. Only
use original blades of the specified type.
