6. CONTROLS AND ADJUSTMENTS
A) FORWARD CLUTCH CONTROL LEVER
This lever only has two positions: engage and disengage. Lowering the lever
engages the clutch and releasing it disengages the clutch. The service brake is
connected to this lever. The brake operates automatically when the clutch is
disengaged.
B) ACCELERATOR CONTROL LEVER
This is used to adjust the number of engine revolutions according to the opera-
tions to be carried out. Hence at switch on the lever will be positioned on the
minimum setting whilst during work operations it will be positioned as required by
use.
C) EMERGENCY BRAKE LEVER
This engages the machine's emergency brake should the automatic brake con-
nected to the forward clutch lever (Fig 1 Ref. A) fail.
WARNING: make sure that the emergency brake lever ( Fig.1 Ref C) is not en-
gaged when operating the forward clutch lever (Fig. 1 Ref . A).
D) FLAIL ROTOR CLUTCH CONTROL LEVER
This is used to engage and disengage rotary movement of the flail holder rotor.
Lowering the lever engages the clutch and releasing it disengages the clutch. The
flail brake is connected to this lever, so the brake operates automatically when the
lever is released and the rotor stops within a few seconds.
WARNING
The flail rotor rotates at high speed if the engine is running and the flail clutch is
engaged, regardless of the position of the forward clutch.
E and E1) RIGHT AND LEFT WHEEL RELEASE LEVERS
These make directional gear changes easier during forward movement or ma-
noeuvring of the machine.
WARNING: never use the release levers instead of the forward clutch control
lever since release of the two wheel release levers at the same time auto-
matically disengages the service brake, thus overriding its safety function.
This precaution must be observed particularly when working on steep
banks.
G) FRONT WHEELS
These are the front support for the machine and they are involved in cutting height
adjustment.

12
H) FRONT GUARD
The front guard ( Fig. 1, ref. H) opens or closes automatically according to the
amount of grass to be cut. Use of the machine with the guard left open is strictly
prohibited. This may cause the outward projection of objects.
The guard may only be set in the open position during flail replacement operations
with the machine switched off.
I) CUTTING HEIGHT ADJUSTMENT LEVER
This lever serves to adjust the cutting height. Warning: if the cutting height is set
too low the following undesirable consequences may occur:
•foreign objects such as stones, etc., may be thrown outwards
•dirt and mud may accumulate inside the rotor guard, thus impeding regular
discharge of cut grass.
•premature flail wear and possible breakage of the same.
L) HANDLEBAR ADJUSTMENT LEVER
The handlebars can be adjusted both vertically and laterally to suit the user and
the working conditions. Set the handlebars at user hip height.
M) ON SWITCH
Two-position switch:
(1)for starting the engine
(0 for switching off the engine
N) SPEED SELECTOR LEVER
This lever is used to select the forward speed of the machine.
The numbered positions indicate the speed settings (1st - 2nd - 3rd) and the letter
N indicates the neutral gear.
WARNING: if the speed selector lever ( Fig. 2 Ref. N) is on the 3rd speed setting
the gear lever (Fig. 2 Ref. O) cannot be set in reverse.
O) GEAR LEVER
This lever is used to select the advance of the machine (forward, neutral, reverse).
Used together with the speed selector lever (Fig.2 Ref. N) it gives 3 forward gears
and 2 reverse gears.
WARNING: if the gear lever (Fig. 2 Ref. O) is set in reverse the speed selector
lever (Fig. 2 Ref. N) cannot be set in the 3rd speed.
WARNING: before operating the gear lever ( Fig. 2 Ref O) it is advisable to set
the speed selector lever (Fig. 2 Ref N) in neutral ( N The required gear should only
be selected after this operation.
WARNING
Be sure to set the lever positions correctly (Fig. 2 pos N and O), making sure that
the levers are correctly engaged; if they are not engage the forward clutch mo-
mentarily (Fig. 1 Pos. A) so that the speed setting engages correctly.
The above operation may prove particularly useful during the machine's first
working hours.

!The guard in front of the flails ( Fig. 1, ref. H) must always be closed while the
machine is in use.
!When switching on the engine check the position of the various control levers
(see the section on “Controls and adjustments”).

15
!Supervise the clothing of personnel operating the machine: a long-sleeved
jacket with close-fitting cuffs, long, close-fitting trousers, heavy-duty footwear,
and a protective cap or helmet should be worn. Avoid wearing loose-tailed
clothing, unbuttoned jackets or torn, undone or partially zipped up items to pre-
vent them from being caught up in the moving parts.
!Safety goggles and ear protection devices must be worn. Safety gloves must
also be worn during machine operation and maintenance.
!Do not switch on and operate the flail mower in enclosed areas since the en-
gine gives off carbon monoxide fumes which are colourless, odourless, taste-
less and extremely dangerous.
!Take care when handling fuel. Fuel is highly flammable and its vapours explo-
sive :
- Only use an approved container
- Take care not to remove fuel caps or top up the tank with the engine running.
- Allow the engine to cool before proceeding with fuel-filling operations.
- Do not smoke during this operation.
- Never fill the machine with fuel in an indoor ambient
- It is advisable to use a wide funnel to prevent spillage of fuel on the engine
and on other surfaces of the flail mower
- If any fuel is spilled do not attempt to switch on the engine; simply move the
machine away from the area of spillage before switching on.
-After filling up with fuel reposition and screw the fuel tank cap right down.
• Do not rest the flail mower or the fuel container in indoor environments with na-
ked flames
d)WORKING USE
!When working keep everyone at a minimum distance of 10 metres from the
machine.
!Keep the engine well ventilated and clog-free (materials and other residue) to
prevent damage to the engine and risk of fire. Clean the cooling fan and fins
regularly. Clean the air filter at the same time as well.
!Drive smoothly, avoiding brusque starts, braking and turns.
!Take care not to touch the silencer when hot.
!When reversing make sure there are no children or animals around. Take care
not to get caught up in the moving parts of the machine.
!If a slipping belt causes abnormal noise, smells or overheating, switch off the
engine immediately and check the machine to prevent the outbreak of fire and
damage to the transmission.
!The rotating flails are extremely dangerous. Keep away from the rotor guard
when the flails are in motion. Do not help the grass into the housing using
hands or feet and do not allow anyone to stand either in front of the machine or
in its direction of travel.

16
WARNING. During work operations the grass is shredded and expelled by the
machine. However, if the grass is damp it tends to build up inside the flail housing,
thus leading to the incorrect feeding of the grass to be cut. The result is that even
on short grass the engine may tend to cut out. Remove the build-up of grass in-
side the housing (with the engine switched off) using a stick of wood, or wait until
the grass dries out before resuming cutting. If during work operations the engine
tends to stop due to overloading, either a slower gear must be used or the cutting
height must be increased, or else only part of the machine working width must be
used.
!When working in a stony or obstacle-riddled area try to remove as many ob-
jects as possible before commencing cutting. Then work at a greater cutting
height than usual.
WARNING
Stones and other objects may be thrown outwards in direction of the opera-
tor or of other persons in the vicinity.
Keep at a safe distance from persons, animals and objects.
!If the cutting mechanism accidentally comes into contact with an object (stump
or stone), switch off the engine and carry out the following operations:
-Inspect the damage
-Do not attempt to repair it if unskilled to do so
-Check that no parts have come loose
!Do not use the machine if it does not work properly or is broken: seek author-
ized service.
!It is strictly prohibited to leave the flail mower running whilst unsupervised.
!It is strictly prohibited to transport the machine with the engine running. When
loading the machine onto a vehicle, the inclination of the ramps must not ex-
ceed 15°.
WARNING!
EXERCISE CAUTION WITH GRADIENTS . Danger of machine overturning.
!Given its outdoor use, it is advisable not to use the flail mower when it is rain-
ing.
!The area next to the engine exhaust may reach a high temperature.
WARNING!
Danger of burns.
!Do not go near water fountains or precipices and do not cross narrow bridges
during work operations to prevent the risk of falling.
!Do not work on steep banks with gradients in excess of 10°.
!Take special care on steep banks; avoid working upstream of the machine so
as not to run the risk of slipping under it, particularly when the ground is wet.
!Avoid working on the shoulder, between flat ground and a steep bank. The
machine may skid or slip.
!In the instance of difficulty or emergency stop simply release the forward clutch
control and flail rotor levers.
!Work on flat ground for the utmost safety.

17
E)AFTER USE.
!Before moving away from the machine, place the gear lever in neutral (see fig-
ure 2, ref.N) and switch off the engine by moving the switch (Fig.2,ref.M) to
the 0 position.

of the machine.
The inclination of the ramps must not exceed 15°.
Recommended length : at least 31/2times the vehicle bed's height from the
ground.
Recommended width : to be chosen according to the tyre width of the machine
!Proceed with the loading of the machine, manoeuvring it carefully. Set the ac-
celerator lever at minimum (Fig. 1, ref. B) and the speed lever ( fig. 2, ref. N) to
the 1st gear setting
!Using the lever as shown in figure 2, ref. O, engage the forward gear for load-
ing, or the reverse gear for unloading.
!During loading/unloading operations on the ramps avoid operating the flail
clutch (Fig. 1, ref. D), the gear lever (Fig. 2, ref. O) and the right and left wheel
release levers (fig. 1, ref. E and E1) because such actions may prove ex-
tremely dangerous.
!Line the front wheels up with the centre of the loading ramps.
!Take care when the machine passes from the loading ramps to the vehicle
bed, because a shift in balance occurs.
!Once loaded, turn off the engine using the relative switch (Fig. 2, ref.M), make

10. DESCRIPTION OF THE SAFETY AND GUARD SYSTEMS
WARNING
The safety devices must never be tampered with. It is necessary to understand how they
work and safeguard their efficiency and correct operation. In the instance of doubt, prob-
lems or malfunction contact your dealer.
FORWARD CONTROL AND FLAIL MOVEMENT LEVERS
When released both of these levers instantly disengage the transmission con-
nected to them, thus automatically engaging their respective brakes, hence the
machine service brake in the first case and flail rotor rotation in the second.
In this way they act as safety devices.
In the instance of difficulty or sudden emergency, the quick release of these levers
will return them to their standard position (raised).
FRONT GUARD
The front guard (Fig. 1, ref. H) opens or closes automatically according to the
amount of grass to be cut. Use of the machine with the guard left open is strictly
prohibited. This may cause the outward projection of objects.
The guard may only be set in the open position during flail replacement operations
with the machine switched off.
11. OPERATIONS TO BE CARRIED OUT BEFORE SWITCHING ON
Position the flail mower outdoors on sufficiently firm, flat soil. Read the instructions
provided by the engine manufacturer in the relative manual and follow them care-
fully to prevent situations arising which may endanger either persons or the ma-
chine.
Then check:
- the state of the flails by inspecting them;
- that all the screws are tightened, particularly those securing the flails;
- that the guards and safety devices are securely tightened.
- Before switching on the flail mower make sure that there are no persons in the
vicinity.
During operation do not allow persons near the machine, especially children. The
operator is responsible for any harm done persons in the working area of the ma-
chine.
Oil recommendations
Before switching on the engine check the oil level and top up, if necessary,
while keeping it in a horizontal position. Do not overfill.
Use of a high-grade detergent oil is recommended (refer to the enclosed engine
manual).
Fuel recommendations
Use of fresh, clean lead-free petrol is advised.
WARNING. IT IS ADVISABLE TO CONSULT THE ENGINE MANUAL BEFORE
SWITCHING ON THE MACHINE.
