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
uctions on checking, maintaining and servicing your
instr
machine.
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to
the machine
.
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
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

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.
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.

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.

GENERAL SAFETY PRECAUTIONS
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.
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! A faulty cutting attachment
may increase the risk of accidents.
!
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 v

FUEL HANDLING
Fuel handling
Never start the machine:
1 If you have spilled fuel on it. Wipe off the spillage and
allo
w remaining fuel to evaporate.
2 If you have spilled fuel on yourself or your clothes,
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
Transport and storage
• Store and transport the machine and fuel so that there
is no risk of any leakage or fumes coming into contact
with sparks or naked flames, for example, from
electrical machinery, electric motors, electrical relays/
switches or boilers.
• When storing and transporting fuel always use
ved containers intended for this purpose.
appro
• When storing the machine for long periods the fuel
tank must be emptied. Contact your local gas station
to find out where to dispose of excess fuel.
• The transport guard must always be fitted to the
cutting attachment when the machine is being
ansported or in storage.
tr
• Ensure the machine is cleaned and that a complete
ser
vice is carried out before long-term storage.
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion

and inhaling fumes.
Fuel
CAUTION! The machine is equipped with a four-stroke
engine. Make sure that there is always sufficient oil in the
oil tank.
.
Gasoline
Always use an unleaded quality petrol of at least 90
octane (RON).
Use low-emission gasoline, also known as alkylate
gasoline, if it is available.
• The lowest recommended octane grade is 87
((RON+MON)/2). If you run the engine on a lower
octane grade than 87 so-called knocking can occur.
This gives rise to a high engine temperature and
increased bearing load, which can result in serious
engine damage.
• When working at continuous high revs a higher octane
ating is recommended.
r
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Engine oil
Check the oil level before starting the machine. A too low
oil level can cause serious damage to the engine.
When the machine is new the engine oil should be

gently.
Tighten the fuel cap carefully after
refuelling.
Always move the machine away from the
refuelling area before starting.
Clean around the fuel cap. Clean the fuel and oil tank
regularly. The fuel filter should be changed at least once

WARNING! Neither the operator of the
machine nor anyone else may attempt to
remove the cut material while the engine
is running or the cutting equipment is
rotating, as this can result in serious
injury.
Stop the engine and cutting equipment
before you remove material that has
wound around the blade shaft as
otherwise there is a risk of injury. The
bevel gear can get hot during use and
may remain so for a while afterwards. You
could get burnt if you touch it.
WARNING! Watch out for thrown objects.
Always wear approved eye protection.
Never lean over the cutting attachment
guard. Stones, rubbish, etc. can be
thrown up into the eyes causing
blindness or serious injury.
Keep unauthorised persons at a
distance. Children, animals, onlookers
and helpers should be kept outside the
safety zone of 15 m. Stop the machine
immediately if anyone approaches. Never
swing the machine around without first
checking behind you to make sure noone is within the safety zone.

WORKING TECHNIQUES
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.
WARNING! Sometimes branches or
grass get caught between the guard and
!
cutting attachment. Always stop the
engine before cleaning.
Cutting
• The trimmer is ideal for cutting grass that is difficult to
reach using a normal lawn mower. Keep the cord
parallel to the ground when cutting. Avoid pressing the
trimmer head against the ground as this can ruin the
lawn and damage the tool.
Grass trimming with a trimmer head
Trimming
• Hold the trimmer head just above the ground at an
angle. It is the end of the cord that does the work. Let
the cord work at its own pace. Never press the cord

CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a

Adjusting the idle speed (T)
Check that the air filter is clean. When the idle speed is
correct, the cutting attachment should not rotate. If
adjustment is required, close (turn clockwise) the idle
adjustment screw T, with the engine running, until the
cutting attachment starts to rotate. Open (turn
anticlockwise) the screw until the cutting attachment
stops. The idle speed is correctly set when the engine
runs smoothly in all positions, and there is a clear margin
to the speed at which the cutting attachment starts to
rotate.

Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Fins on the flywheel.
3 Cooling fins on the cylinder.
4 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more

• Loss of engine power
• Unnecessary wear to engine parts
• Excessive fuel consumption.
