5. INSTRUCTIONS FOR USE
5.1. OPERATION OF THE BLOWER
The implement is suited only for the use described. Any other use deferring from the one described in
this owner's manual can damage the machine and be a hazard to the user.
The good performance of the implement depends on its proper use and an adequate maintenance. It is, therefore,
advisable to follow closely the directions contained herein, so as to prevent any inconvenience which may impair the
good performance and the life span of the machine. It is also important to follow the directions contained in this
owner's manual, because the Manufacturer cannot be held responsible for damages caused by negligence or the
non-observance of the directions. The hydraulic system driving the air-pump must be used, serviced and repaired by
personnel having a perfect knowledge of the unit itself and of the hazards it may present. Check the correct plugging
of the quick couplings: unless they are correct, damages may occur to the components of the system. Only
disconnect hydraulic connections after they have been de-pressurized.
The leaking of oil under pressure may cause skin wounds and severe infections. Should this happen,
consult a doctor immediately. It is absolutely forbidden to install hydraulic components inside the
tractor cab.
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 50l/min. the hydraulic operation requires 24 l/min.
•
Working pressure: 100 ÷ 130 Bar Max 150 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 rotational speed of the hydraulic motor and, as a consequence, of
the suction unit depends on the flow pressure, which is shown on the
manometer.
The system is complete 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.
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 3 Bar.
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
