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.
BOOTS
Wear sturdy, non-slip boots.
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.
FIRST AID KIT
Always have a first aid kit nearby.
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.

s vibration damping system reduces the transfer
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.
These 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.
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
Grass blades and grass cutters are intended for cutting
coarse grass.
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.
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.
A trimmer head is intended for trimming grass.
Locking nut
A locking nut is used to secure some types of cutting
attachment.

SAFETY INSTRUCTIONS
• 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.
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.
General rules
1 Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
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.
2 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.

SAFETY INSTRUCTIONS
Cutting equipment
IMPORTANT!
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.
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! Using an incorrect cutting
attachment or an incorrectly sharpened
!
blade increases the risk of kickback.
Sharpening grass cutters and grass blades
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.
• 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.
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.

change your clothes. Wash any part of your body that
has come in contact with fuel. Use soap and water.
3 If the machine is leaking fuel. Check regularly for leaks
from the fuel cap and fuel lines.
4 Avoid all skin contact with fuel. Fuel is a skin irritant
and may even cause skin changes.
WARNING! When the engine is started with
the choke in either the choke or start throttle
!
positions the cutting attachment will start to
rotate immediately.
• The complete clutch cover and shaft must be fitted before
the machine is started, otherwise the clutch can come

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
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 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.
Grass clearing using a grass blade
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 can lead to dangerous
conditions, e.g. slippery surfaces.
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.
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.
• 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.
