Page 293.1 Operation of the blowerThe implement is suited only for the use described. Any other use deferring from theone described in this owner’s manual can damage the machine and be a hazard to theuser.The good performance of the implement depends on its proper use and an adequate maintenance. Itis, therefore, advisable to follow closely the directions contained herein, so as to prevent any inconve-nience which may impair the good performance and the life span of the machine. It is also importantto follow the directions contained in this owner’s manual, because the Manufacturer cannot be heldresponsible for damages caused by negligence or the non-observance of the directions. The hydrau-lic system driving the air-pump must be used, serviced and repaired by personnel having a perfectknowledge of the unit itself and of the hazards it may present. Check the correct plugging of the quickcouplings: unless they are correct, damages may occur to the components of the system. Only dis-connect 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 installhydraulic components inside the tractor cab.3.1.1Hydraulic connection with the tractorCheck 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 (fan speed 4200÷4500 rpm, max 4600 rpm)• 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 tractorhydraulic distributor, through a delivery hose 1⁄2 A.The rotational speed of the hydraulic motor and, as a consequence, ofthe suction unit depends on the flow pressure, which is shown on themanometer.The system is complete with a safety valve which makes it possible forthe device to keep on turning by inertia even after the system has beenshut off or a sudden break down of the system has occurred.For a correct performance it is important to connect the flow dischargehose 3⁄4 G of the hydraulic motor to a free flow discharge plug of thetractor; this free discharge cannot present any counter-pressure excee-ding 3 Bar.This connection is of basic importance above all to protect the hydraulicseals of the motor, which, if damaged, would allow very dangerous oilleaks.A) Quick coupling on the delivery side 1⁄2 B) Three-way electro-valveC) ManometerD) MotorE) Free-flow dischargeF) Safety valveG) Quick coupling on free-flow discharge 3⁄4 H) Flow-adjusting device(option)3.
