fatal if inhaled.

Organic material from
grass and shrub can cause discomfort to
sufferers of hay fever and other allergies.
Use an appropriate mask or other
breathing protection.

STARTING THE ENGINE

FUEL MIXTURE: 25 : 1

Use fresh, unleaded petrol (95 RON) and
100 % synthetic oil specially made for
high performance two stroke engines. Mix
it in a ratio of 25 parts of petrol to 1 part of
oil.
Using synthetic oil specially made for two­stroke engines, will reduce the formation
of ashes and carbon deposits in the spark
plug, the piston, the muffler and in the
cylinder as well as reducing emissions of
harmful exhaust gases. Lubrication will be
maximised and the engine’s life extended.

It is important only to use good quality,
fresh petrol and oil. The mixture should
be used within three weeks of being
prepared.

The petrol and oil must be
mixed prior to filling the fuel tank. For
best results, add the oil to the fuel can
after the petrol. This operation must be
carried out in a well ventilated area
away from naked flames, sparks or
lights and with the engine switched off.
Never smoke or use a mobile telephone
when carrying out this operation. Shake
the mixture well in the fuel can and the
engine fuel tank before use.

To fill the fuel tank, unscrew the cap of the
tank and, using a filler, pour the petrol/oil
mixture into the tank. Take care not to spill
any mixture around and/or on your
clothing. In the event of a spillage, wipe
away immediately.

To avoid a fire risk, start the engine at least
three metres away from the area where the
fuel tank had been filled.

Never fill the fuel tank when the engine
is hot.

ENGINE STARTING

To start the engine, proceed as follows:

1. Move the throttle control lever and

push the red button on the right handle
to the “START” position ‘U’ handle
models.

2. Push the “primer” button under the

carburettor, 4 or 5 times, to allow the
petrol to reach the clear plastic pipe by
the fuel tank..

3. Move the choke lever of the carburettor

to the closed position.

4. With your left hand, grip the

brushcutter and hold the transmission

shaft firmly on the ground. With the
right hand, slowly pull the recoil starter
handle until engagement of the pawls
with the flywheel is felt.

5. Pull the recoil starter handle firmly for

4 or 5 times until the engine starts. The
red button will return to its original
position when the throttle lever is
engaged.

6. After starting release the choke lever to

the open position: .

7. To avoid damage to the recoil starter,

never pull the cord to its entire
length.

Should the engine become flooded, turn
the ignition switch off, unscrew the spark
plug, wipe it dry or replace, pull the recoil
starter several times, without the spark
plug in place and choke in the open
position. This will help clean and ventilate
the combustion chamber.

IMPORTANT :
When the engine is at operating
temperature, these operations are not
necessary. Pull the recoil starter until
the engine starts.

When the engine is at idling speed, the
cutting head should not rotate. If it does,
seek the assistance of your dealer who
will carry out the necessary adjustments.

RUNNING IN

During the first ten hours of work, run the
engine at a moderate speed. Do not run the
engine at maximum speed for prolonged
period until all the components have
bedded in. After the engine has been run in,
it will reach its maximum power.

After the two first hours of work, check
that all nuts and screws are securely
fastened and tighten if necessary.

USING THE BRUSHCUTTER

Which setting to use with each
cutting head ?

The safety guard is two coloured the
main part red and the small blade
holder is black.

1. When using the nylon head:

The safety guard must be used with
both parts in position; (main part
red + the small black blade holder).

2. When using the 3 tooth blade.

Remove the small black blade
holder (with a screwdriver) and use
only the main red safety guard.

Only use the cutting tools
supplied by the manufacturer.
All other blades, particularly
SAW BLADES, are
FORBIDDEN.

This brushcutter is only made to cut
grass, bush and light shrub.

* Ensure the machine is perfectly
balanced between the engine and the
cutting head. The cutting head must be
parallel to the ground and should not
require to be held in position.
* Ensure everything in the assembly is
in good working order by operating the
throttle gently for a few times without
reaching maximum engine revolutions.
* Make sure the cutting head is
completely stationary before moving to
the working area. Always carry the
machine with the cutting head below
waist height and as far away from the
body as possible. Make sure there are
no other people, animals or other
objects within a 15 metre radius.

The correct operating stance must have
both feet placed firmly on the ground
and the body well balanced.

Grass cutting

Cut the grass in 1.5 metre widths,
keeping the machine well balanced and
each step firm. When using the 3 tooth
blade for grass or shrub, always cut
from right to left to leave the debris on
the left for collection at a later time.

Try to avoid engaging stones, piles of
earth, small pieces of wood or anything
that could be hidden or difficult to see
in the grass. If a large object is
accidentally struck or if the cutting
head gets blocked or overloaded or
stringy material gets wrapped in the
cutting head: reduce the engine speed
to the idle speed to disengage the
clutch. Make sure that the cutting head
has stopped rotating switch off the
engine.
Put the brushcutter on the ground and
check that the cutting tool has not been
damaged e.g. broken teeth on the blade
or a cracked component. If necessary,
change the cutting head. If the head is
only wrapped by vegetation, remove
by hand and clean the cutting head.
Always wear safety gloves for this

operation and only with the engine
switch off and the head stationary.

When the 2 nylon cords become too
short, accelerate the engine and bump
the nylon head on the ground,
automatically the 2 nylon cords will
feed out and be cut to the correct
length. Repeat the operation if
necessary.

CORRECT USE OF THE 3 TOOTH
BLADE.

All safety systems and parts
of the machine must be in good order
when the brushcutter is in use.

When using the 3 tooth blade, avoid
the risk of serious injury by adopting
good safety practices. Pay attention to
the drawing below.

When cutting woody and fibrous
materials always use the 3 tooth blade in
the circular direction “A” below.

The circular position “B” is
acceptable only if the brushcutter is
gripped very tightly. It is not
recommended.

The circular position “NO” is
forbidden as it can endanger people,

animals and other objects. Never use

this position.

NO!

A

B

All safety devices and
safety equipment must be maintained in
good operational condition at all times.

The engine and cutting head must be at
a complete standstill during assembly,
repair and cleaning operations.
Put the ignition switch to the “STOP”
position.

Brushcutters vibrate during use. Although
equipped with an anti-vibration device, the
vibrations can generate increased fatigue.
For this reason it is recommended that
regular pauses be taken during work.

It is also recommended that, after a few
hours of work, the machine be allowed to
idle at low rpm’s for a few minutes to
allow the engine to cool.
