5. USER INSTRUCTIONS
5.1. OLEODYNAMIC BLOWER MOVEMENT
The equipment is only suitable for the uses that are indicated. Using the machine for other purposes can
damage it and endanger the machine operator.
Use the equipment correctly and carry out maintenance regularly to keep the machine working correctly. Follow instructions
scrupulously to avoid problems that could prevent good machine operation and duration. Users must follow the instructions given
in this manual because the Manufacturer cannot be held responsible for any damage or injury caused by negligence and non-
observance of such instructions. The oleodynamic movement of the blower must be used, kept and repaired by personnel who
know the machine perfectly and the relative dangers. Make sure that the quick couplings are connected correctly. If they are not,
the system components can become damaged. Disconnect the oleodynamic connections only after depressurising them.
Consult a doctor immediately if pressurised oil leaks come into contact with the skin. This kind of injury can
lead to serious infections. It is totally FORBIDDEN to install oleodynamic components in the tractor cabin.
5.1.1. HYDRAULIC CONNECTION WITH THE TRACTOR
Check in the Owner’s Manual of the tractor its hydraulic features, which must be as follows:
Hydraulic system of the “CLOSED CENTER” (also called LOAD SENSING )type
Pump with variable displacement
Oil delivery exceeding 100 l/min. the hydraulic operation requires 45 l/min.
Working pressure: up to 18 0 Bar
Oil cooling: should the tractor not be equipped with an adequate cooling system it is necessary to install one
The tractor must be suited to receive a free-return flow connector (NO COUNTERPRESSURE)
The oil flow necessary to drive the blower is taken from the tractor
hydraulic distributor, through a
delivery hose ½ A.
The rotation speed of the hydraulic motor, and therefore the blower, is
connected to the oil flow adjustable from the tractor’s controls.
The hydraulic motor has a security system with a safety valve which makes
it possible for the device to keep on turning by inertia even after the system
has been shut off or a sudden break down of the system has occurred.
The pression gauge (0-10 bar) on the hydraulic valve allows to check the
backpressure value.
For a correct performance it is important to connect the flow
discharge
hose ¾ G
of the hydraulic motor to a
free flow discharge plug of the
tractor
; this free discharge
cannot present any counter-pressure
exceeding 2 Bar
.
The manometer C
on the unloading checks these
backpressures.
This connection is of basic importance above all to protect the hydraulic
seals of the motor, which, if damaged, would allow very dangerous oil
leaks.
A) Quick coupling on the
delivery side ½
B) Motor
C) Manometer backpressures on unloading
D) Quick coupling on
free-flow discharge ¾
E) Free-flow discharge
