CHECKING THE MACHINE
Before starting work please:
– check that all the screws on the machine and
the cutting device are tightly fastened;
– check that the cutting device is undamaged
and that the 3 or 4-point metal blades (if fitted)
are properly sharpened;
– check that the air filter is clean;
– check that the protection devices are well fas-
tened and working efficiently;
– check the handgrips are well fastened.
PREPARING THE FUEL
This machine is fitted with a two-stroke engine
which requires a mixture of petrol and lubricating
oil.
Using petrol alone will damage the motor and will cause for invalidation of
the warranty.
Only use quality fuels and
oils to maintain high performance and guarantee
the duration of the mechanical parts over time.
• Petrol characteristics
Only use unleaded petrol with a fuel grade of at
least 90 N.O.
Unleaded petrol tends to
create deposits in the container if preserved for
more than 2 months. Always use fresh petrol!
• Oil characteristics
Only use top quality synthetic oil specifically for
two-stroke engines.
Your dealer can provide you with oils which have
been specifically developed for this type of
engine, and which are capable of guaranteeing a
high level of protection.
The use of these oils makes it possible to prepare a 2% mixture, consisting in 1 part oil to 50
parts petrol.
In the event that no specific oil is available, it is
IMPORTANT
IMPORTANT
IMPORTANT
possible to use a mineral lubricating oil for
engines (class FA or FB), where in this case the
mixture must be 4%, i.e. 1 part oil and 25 parts
petrol.
•Preparation and preservation of the fuel
mixture
Petrol and the fuel mixture are highly inflammable!
– Keep the petrol and fuel mixture in homolo-
gated fuel containers, in safe place, away
from any flames or heat sources.
– Never leave the containers within the reach
of children.
– Never smoke whilst preparing the mixture
and avoid inhaling the petrol fumes.
The chart indicates the amount of petrol and oil
to use to prepare the fuel mixture according to
the type of oil used.
To prepare the fuel mixture:
– Place about half the amount of petrol in a
homologated tank.
– Add all the oil, according to the chart.
– Add the rest of the petrol.
– Close the top and shake well.
The fuel mixture tends to
age. Do not prepare excessive amounts of the
fuel mixture to avoid deposits from forming.
Keep the petrol and fuel mixture containers separate and easily identifiable to
avoid the mistake of using one in place of the
other.

USING THE MACHINE 11
To respect people and the environment:
– Try not to cause any disturbance.
– Scrupulously comply with local regulations
and provisions for the disposal of waste
materials after sawing.
– Scrupulously comply with local regulations
and provisions for the disposal of oils,
petrol, damaged parts or any elements
which have a strong impact on the environment.
Prolonged exposure to
vibrations can cause injuries and neurovascular disorders (also called “Renaud’s syndrome” or “white hand”), especially to people
suffering from circulation disorders. The
symptoms can regard the hands, wrists and
fingers and are shown through loss of sensitivity, torpor, itching, pain and discolouring of
or structural changes to the skin. These
effects can be worsened by low ambient temperatures and/or by gripping the handgrips
excessively tightly. If the symptoms occur,
the length of time the machine is used must
be reduced and a doctor consulted.
Always wear suitable
clothing when using the machine. Your dealer can provide you with all the information on
the most suitable accident-prevention
devices to guarantee your safety.
USING THE WEBBING (Fig. 12)
The machine must always
be used connected to the webbing worn correctly. Frequently check the efficiency of the
quick release mechanism used to quickly free
the machine from the belts in case of danger.
The webbing must be put on before connecting
the machine to the special coupling and the
belts must be adjusted to suit the operator’s
height and stature.
If the machine has more than one coupling hole,
use the most favourable point for keeping the
machine balanced when working.
!
WARNING!

WARNING!
!
WARNING!
Always use webbing suited to the weight of the
machine and the cutting device used
– the single or double belt models can be used
for machines weighing less than 7.5 kg fitted with the cutting line head or 3 or 4-point
blades;
– the double belt model must be used for
machines weighing more than 7.5 kg fitted
with the saw blade
(if permitted).
•
Single belt “MONO” models
The belt (1) must go over the left shoulder
towards the right hip.
• Double belt models
The belt (2) must be worn with:
– the padded part and snap-hook coupling on
the right;
– the release in front;
–the belt cross-over on the operator’s back.
The belts must be tensioned so that the load is
evenly distributed on the shoulders.
•
“FLEX” models
Wear the webbing harness like a normal backpack.
Tension the belts so that the load is evenly distributed on the shoulders, fasten the waist belt
and connect the elastic to the plate.
USING THE MACHINE
When working, the
machine must always be firmly held in both
hands, keeping the power unit on the right of
the body and the cutting group below the line
of the belt.
Stop the engine immediately if the blade stops during sawing. Always
beware of a kickback, which could occur if a
blade encounters a solid object (logs, roots,
branches, stones, etc.). Do not touch the

ground with the blade. Kickbacks cause
blade recoils that are difficult to control, so as
to cause loss of control of the machine, compromise operator safety and cause damage
to the machine itself.
Before tackling a mowing job for the first time it
is advisable to gain the necessary familiarity with
the machine and the most suitable cutting techniques, finding out how to wear the webbing correctly, firmly gripping the machine and making
the movements required by the job.
•
Choosing the cutting device
Choose the most suitable cutting device for the
job to be done, according to these general indications:
–
the 3-point blade is suitable for cutting
brushwood and small shrubs up to 2 cm in
diameter;
–
the 4-point blade is suitable for cutting resistant grass over large surfaces;
–
the cutting line head can eliminate tall grass
and non-woody vegetation near fences, walls,
foundations, pavements, around trees, etc. or
to completely clean a particular area of the
garden;
–
the saw blade (if permitted) is suitable for cutting resistant bushes, shrubs and small trees
with a trunk up to 6 cm.
WORKING TECHNIQUES
a) 3-point blade (Fig. 13)
Start cutting above the undergrowth and then
move down with the scything blade so as to cut
the brush into small pieces.
b) 4-point blade (Fig. 14)
Proceed using the machine as a traditional
scythe, with a circular movement of about 6090°, thus moving outside the undergrowth, and
so on.
c) Cutting line head
Use ONLY nylon lines. The
!
WARNING!
use of metal lines, plasticised metal lines
and/or lines not suitable for the head can
cause serious injuries and wounds.
During use it is advisable to stop the engine periodically and remove the weeds wound round the
machine, so as to prevent the drive tube from
overheating due to the grass caught under the
guard.
Remove the caught-up grass with a screwdriver
to allow the rod to be properly cooled.
Do not use the machine
for sweeping, tilting the cutting line head.
The power of the engine could throw objects
and small stones 15 metres or more, causing
damage and injuries to people.
• Cutting in motion (Scything) (Fig. 15)
Proceed at a regular pace, with a circular motion
similar to a traditional scythe, without tilting the
cutting line head during the operation.
First try cutting at the right height in a small area,
so as to then achieve a uniform cutting height
keeping the cutting line head at a constant distance from the ground.
For heavier cutting it can be useful to tilt the cutting line head by about 30°.
Do not work in this way if
there is the possibility of causing objects to
be thrown, which could harm people and animals and cause damage.
• Precision cutting (Trimming)
Keep the machine slightly tilted so that the lower
part of the cutting line head does not touch the
ground and the cutting line is at the required
point, always keeping the cutting device at a distance from the operator.
• Cutting near fences/foundations (Fig.16)
Slowly approach the cutting line head to fences,
posts, rocks, walls, etc. without hitting them
hard.
!
WARNING!
!
WARNING!
If the line strikes a solid object it could break or
become worn; if it gets tangled in a fence it
could break abruptly.
In any case, cutting around pavements, foundations, walls, etc. can cause greater wear than
normal in the line.
• Cutting round trees (Fig.17)
Walk round the tree from left to right, approaching the trunks slowly so as not to strike the tree
with the line and keeping the cutting line head
tilted forward slightly.
Remember that the nylon line could lop or damage small shrubs and that the impact of the
nylon line against the trunk of bushes or trees
with soft bark could seriously damage the plant.
•
Adjusting line length when working (Fig. 18)
This machine is fitted with a “Tap & Go” head.
To r elease more line, tap the cutting line head
against the round with the engine at top speed:
the line will be released automatically and the
knife cut off the excess length.
d) Saw blade (if permitted) (Fig. 19)
Use of the saw blade is
prohibited on machines marked with the specific symbol (see chap. 2 n° 6). When using
the saw blade, where permitted, the specific
guard must always be fitted. The blade must
always be well sharpened to reduce the risk
of kickback.
When felling small trees,
estimate the direction in which the cut tree
will fall, also taking the wind direction into
consideration.
To get a good result when felling small trees, the
cut must be made with a rapid movement
towards the branch or trunk to be cut, with the
engine at maximum revs.
!
WARNING!
!
WARNING!
Do not use the right-hand area of the blade
because there is a high risk of kickback or the
blade seizing up, due to the direction of rotation.
END OF OPERATIONS
When you have finished your work:
– Switch off the engine as indicated above
(Chap. 6).
–Wait for the cutting device to stop and fit the
blade guard (if 3 or 4-point blades of saw
blades are used).

Periodically remove and clean the spark plug
using a metal brush to get rid of any deposits.
Check and reset the correct distance between
the electrodes.
Replace the spark plug and fasten it firmly using
the supplied wrench.
The spark plug must be replaced with one with
the same characteristics whenever the electrodes have burnt or the insulation has worn, and
in any case every 100 working hours.
TUNING THE CARBURETTOR
The carburettor is tuned by the manufacturer to
achieve maximum performance in all situations,
with a minimum emission of toxic gas in compliance with the regulations in force.
In the case of poor performance contact your
Dealer for a check of the carburetion and engine.
•
Tuning minimum speed
The minimum speed must
only be tuned if the cutting device moves
when the engine idles.
Speed is reduced by turning the screw marked
«MIN» anti-clockwise until the cutting device
stops moving. The engine should continue to run
as normal.
If the engine does not idle smoothly, turn the
screw clockwise to increase the speed.
