PUTTING INTO USE

General safety tips for the use of the machine

Tips for manoeuvres with the machine

There is a danger of overturning when you work on slopes.

Driving should be adapted to the terrain and ground conditions.

The tractor vehicle should be equipped in a sufficient form with

weights at the front or at the back in order to guarantee the capacity

to drive and brake (a minimum of 20% of the tare weight of the

vehicle on the forward axle).

Transporting people on the machine is not permitted.

Tips for coupling and uncoupling

There is a risk of injury when you couple the device to the tractor!

While the machine is moving backwards, do not pass between it and

the trailer during the coupling.

It is strictly prohibited to place yourself between the tractor and the

machine if these have not been totally immobilised with a parking

brake and/or blocks on the wheels.

The coupling or uncoupling of the transmission cardan should only be

undertaken when the motor has stopped.

Take care when opening the lid of the blades disc!

For the purposes of maintenance, the lid of the blades disc

must be opened regularly.

After stopping the P.T.O. of the tractor, remove the transmission cardan,

there is risk of injury if the P.T.O. is started up accidentally.

Opening of the blades disc lid

The blades disc lid is equipped with a safety system that prevents it from opening unless the blades disc

has completely stopped. It operates as follows:

Press the green button (2) to unlock the door (1). If the orange light (3) goes on, this means the blades

disc is still in motion (sensor 4 is still detecting motion) and the system is still preventing the lid from

opening. If the green light (5) also goes on, this means the disc is already

stopped; it will blink for 5 seconds until it goes on permanently, indicating the

system is unlocked, and allowing you to open the door (1) by pulling handle (6).

After 15 seconds, the system locks again. If the door (1) is still closed,

press the green button again.

6

While the door (1) is open, or if it is not properly closed, light (7) remains on.

In case of electrical malfunction or in the absence of electric power supply (maintenance/storage) the

system stays locked; to unlock it, use key (8), supplied with the machine, and turn it to UNLOCK.

After repairing the malfunction or after making the electrical connection to the tractor, lock the system

again by turning the key to LOCK; if you forget to do so, the light will stay on, turning off as soon as you

turn the key to LOCK.

Remove the key and keep it together with your tractor's key.

Parking/storing the equipment:

When the equipment is parked, remove the transmission cardan and store it or secure it with a chain.

Only use the machine in accordance with the regulations!

Usage Regulations:

- See "Technical Information" Chapter.

- See "Definition of use of the machine" Chapter.

The load limits of the machine may not be exceeded.

Additionally, comply with the power limits of the tractor to be used.

Travelling on public routes

- Comply with the traffic rules in force.

- Lighting devices should be installed, applied perpendicular to the route.

- Pay attention to the total height of the machine, it must not exceed 4 m from the ground; for this, use

the hydraulic articulation of the discharge pipe (see chapter “how to fold down the pipe”)

FIRST CONNECTION TO THE TRACTOR

HYDRAULIC CONNECTION

VERY IMPORTANT: Before making the hydraulic

connection to the tractor, check the oil condition. If it

is contaminated, change it, otherwise the hydraulic

block and remaining hydraulic components of your

machine could be damaged.

The machine needs 1 double hydraulic circuit, to

activate the hydraulic block, in order to do this:

- Connect the pressure line (1) and the oil return tube (2) (the

tube with the bigger diameter is the oil return tube), the

command lever of the line on the tractor has to be positioned so

that the hose of the greatest diameter is making the return to

the tank.

Note:

If the oil heats up during functioning, and the tractor only has a

constant flow rate pump, then it should be linked to a

simple effect line (see image).

- Connect the pressure hose (1) to the single action control unit.

Connect the oil return hose (2) (with the bigger diameter) to a

direct connection to the oil deposit.

If the tractor allows it, reduce the oil flow rate

REGULATION OF THE HYDRAULIC BLOCK:

Pos. "H±10 mm" to closed hydraulic system

Tractor with variable flow rate pump

Before making the connection, the LS screw on the hydraulic

block should be adjusted to the quota of ±10 mm (totally fasten

LS)

Pos. "H±17 mm" to open hydraulic system

Tractor with constant flow rate pump

The position of the LS screw on the hydraulic block should be

adjusted to a quota of ± 17 mm. (totally unfasten LS)- (factory

configuration).

Warning!

If this is not done, the overload valve on the hydraulic system of

the tractor is continuously in use and an excessive heating of the

oil will take place.

If the tractor has a closed hydraulic system and the hydraulic block

is in the position "A=17" then the hydraulic oil will heat up

(especially due to the constant pumping of the maximum quantity

of oil).

Solution: Place the tuner LS on pos. “A=10 mm”

Coupling the machine to the tractor

- Before coupling the machine, check whether the tractor has counterweights at the front or at the back

(in accordance with the machine application at the back or at the front, respectively), required to balance

the weight of the machine (2150 Kg).

- Couple the machine to the 3 points of the tractor, so that it is parallel to the ground; in order to do this,

adjust the bar (1) and, if necessary, the coupling (2)

- The distance between the tractor's PTO end and the machine's PTO should be approximately 800 mm

(min.); if the arms of the tractor do not allow it, you will have to use an extension (3) and choose the

required distance, which can be of 125; 160 or 195.

If necessary, shorten the cardan, but you are only allowed to do it in the ridged side

Check that there is no interference of the sliding zones by lowering and raising the machine; should it

occur, it could damage the transmission box of the machine.

Attention!

- The admissible angle (35º) of the transmission cardan should not be exceeded, when raising the

machine to carry out manoeuvres, disconnect the PTO of the tractor.

- The minimum quota of overlapping of the transmission cardan sliding zones should be 150 mm (see

chapter on the P.T.O. transmission cardan).

- Couple the machine to the tractor only when all of the safety shields are in place.

- When you couple trailers or accessories to the tractor you should take special care!

Lateral adjustment of the machine in relation to the tractor.

The machine may work centrally aligned with the tractor or displaced about 300 mm to the right (if the

width of the tractor is over 2.3 m); for each of the positions, the front transmission box will have to be

positioned differently, so that the cardan angle does not exceed what is recommended.

The position change is carried out by the hydraulic cylinder (5), activated in the command.

-Hang the machine on the tractor arms

-Remove the latch (3)

-Activate the cylinder (5)

-The tubular stay (2) holding the machine, slides in the support cat. II or III.
