							24PREPARING TO WORKEN
CHECKING THE MACHINE
Before starting work please:
–Check that all the screws on the machine and
the blade are tightly fastened;
–check that the blades are sharp and there are
no signs of any damage;
–check that the air filter is clean;
–check that the protection devices are well fas-
tened and working efficiently;
–check that the handgrips are well fastened
PREPARING THE FUEL 
This machine is fitted with a two-stroke engine
which requires a mix of petrol and lubricating oil.
Using petrol alone will dam-
age 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 (green petrol) with
octane number no less than 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 retailer can provide you with oils which
have been specifically studied for this type of
engine,  which are capable of guaranteeing a
high level of protection.
The use of these oils makes it possible to pre-
pare a 2% mix, consisting in 1 part oil to 50 parts
petrol.
In the event that no specific oil is available, it is
possible to use a mineral lubricating oil for

IMPORTANT
engines (class FA or FB), where in this case the
mix must be 4%, that is 1 part oil and 25 parts
petrol.
•Preparation and preservation of the fuel
mix
Petrol and the fuel mix are highly inflamma-
ble!
–Keep the petrol and fuel mix in homologat-
ed 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 mix and
avoid inhaling the petrol fumes.
The chart indicates the amount of petrol and oil
to use to prepare the fuel mix according to the
type of oil used.
To prepare the fuel mix:
–  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 mix tends to age. Do
not prepare excessive amounts of the fuel mix to
avoid deposits from forming.
Keep the petrol and fuel mix
containers separate and easily identifiable to
avoid the mistake of using one in place of the
other.

engine if the blades block while running or if
they get caught up in the hedge branches
It is recommended to trim the two vertical sides
of the hedge before trimming the top.
•
Vertical trimming  (Fig. 6)
Il taglio deve essere eseguito con un movimento
ad arco dal basso verso l’alto, tenendo la lama il
più distante possibile dal corpo.
•
Horizontal trimming (Fig. 7)
The best results will be obtained with the blade
slightly inclined  (5°- 10°) in the direction you are
cutting, proceed with a curved movement, slow-
ly and without interruptions, especially in the
case of very thick hedges.
LUBRICATING THE BLADES DURING JOBS 
If the trimming device overheats whilst working,
it is necessary to lubricate the internal surfaces
of the blades..
This operation must only
be performed when the blades have stopped
running and the engine is switched off.
END OF OPERATIONS
When you have finished your work:
–Switch off the engine as indicated above
(Chap. 5).
–Wait for the blades to stop and replace the
protection device.

Correct maintenance is essential to maintain the
original efficency and safety of the machine over
time.
During maintenance oper-
ations:
–remove the spark plug cap.
–Wait until the engine is sufficiently cold.
–Use protective gloves when handling the
blades.
–Keep the blade protection devices on,
except when intervening directly on the
blade.
–Never dispose of oils, fuel or other polluting
materials in unauthorised places
CLEANING THE ENGINE AND THE SILENCER
To reduce fire risks, periodically clean the cylin-
der flaps with compressed air and clear the
silencer area from branches, leaves or other
debris.
CLEANING THE AIR FILTER
Cleaning the air filter is
essential to guarantee the efficiency and duration
of the machine.  
It must be cleaned after every 8-10 working
hours.
To clean the filter  (Fig. 8):
–Loosen the screw (1) remove the cover (2) and
the filter element (3).
–Gently tap the filter element (3) to remove the
dirt and, if necessary, clean it with low pres-
sure compressed air.
The filter element (3)must
never be washed and must be replaced if it is too
dirty or damaged
–Replace the filter element (3) and the cover (2)
and tighten the screw (1).
FUEL FILTER
Inside the fuel tank there is a filter which pre-
IMPORTANT
IMPORTANT
!WARNING!
vents impurities from entering the engine.
The filter should be replaced once a year by your
Retailer.
CHECKING THE FUEL TANK CAP (Fig. 9)
If the fuel tank cap exhaust does not function
properly it will prevent the fuel from reaching the
carburettor, which will cause problems during
startup and while the engine is running.
–Check that the exhaust outlet is maintained
clean (1).
–Make sure the pipe (2) and the valve (3) are
correctly fitted as indicated:
a) the valve base (3) must be firmly fastened
to the internal ridge on the cap;
b) the pipe clamp (2) must be attached to the
protrusion at the base of the valve. The pipe
must not be deformed or slack.
CHECKING THE SPARK PLUG
Periodically, remove and clean the spark plug
from any eventual deposits using a metal brush.
Check and reset the correct distance between
the electrodes (Fig. 10).
Replace the spark plug and fasten it firmly using
the supplied key. 
The spark plug must be replaced with one with
the same characteristics in the cases where the
electrodes have burnt or the insulation has worn
out, 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
of use, with a minimum emission of toxic gas in
compliance with current specifications.
In the case of poor performance, first check that
the blades are not partially blocked or deformed,
7. MAINTENANCE AND PRESERVATION  
						

							MAINTENANCE AND PRESERVATION 29EN
on the contrary ask your Retailer to check the
carburettor and the engine.
•
Tuning minimum speed  (Fig. 11)
The minimum speed must
only be tuned if the blades move when the
engine is ticking over.
Reduce the speed by turning the screw (1)
counter-clockwise until the blades come to a
halt and function correctly.
If the engine does not tick over regularly, turn the
screw (1) clockwise to increase the speed.
The blades must not move
when the engine ticks over; contact your
retailer if you are not able to tune it to your
satisfaction.
LUBRICATING THE REDUCTION GEAR (Fig.
12)
Every 20 working hours, top up the level with
special molybdenum bisulphur lubrication,
injecting it into the lubricator (1).
ADJUSTING THE BLADES
The blades are subject to progressive wear,
which is noticed by a decrease in the trimming
performance due to excessive play of the unit.
Switch off the engine and
wait until the blades come to a halt before
performing any adjustments.
Proceed with the adjustment by  (Fig. 13):
–Loosen the nuts   (1).
–Carefully remove any dust or debrit from the
screw (3) slots (2).
–Tighten the screws (3) as far as possible, with-
out over-tightening, and then unscrew them
by  1/4 - 1/2 a turn.
–Then tighten the nuts (1).
–Lubricate the blades.
–Start the engine and let it run at maximum
speed for about 1 minute.
!WARNING!
!WARNING!
!WARNING!
–Switch off the engine and wait for the blades
to come to a halt and then touch them with
your hand; if you can manage to touch them
with your hand without them being too hot,
the blades are adjusted correctly.
–If they have overheated, slightly loosen the
nuts (1) and the screws (3) and repeat the test
until you achieve satisfactory results.
Always check that the nuts
(3) are tightened as far as possible before
starting work.
SHARPENING THE BLADES
It is necessary to sharpen the blades when the
trimming performance decreases and the
branches tend to stick together.
Always replace and never
repair a blade which has blunt cutting edges
We recommend you take
your machine to your Retailer for sharpening as
he has the required tools and suitable experi-
ence.
In order to sharpen the blades, it is recommend-
ed to use a fine grain file and proceed as follows
(Fig. 14):
–Place the file (1) on the blade (2) at a 45°angle,
and proceed with upward strokes towards the
cutting edge.
–Make sure that you put pressure on the file
only when stroking upwards and raise it from
the blade when you move it back towards you.
–Only remove a smallest amount of material.
–Eliminate any burr with a grinding stone.
–Eliminate all grinding traces and lubricate the
blades before reassembling them.
EXTRAORDINARY INTERVENTIONS 
All maintenance operations not foreseen in this
manual must be performed exclusively by your
Retailer.
All and any operations performed in unautho-
rised centres or by unqualified persons will total-
ly invalidate the warranty.
