CONNECTIONS
Connect the fan's small hydraulic
hose line to a pressurised tractor
control unit.
The fan's 1/2'' hydraulic hose line
should be connected to a depres-
surised return tractor control unit.
IN THE RETURN LINE THE PRESSURE MUST BE A MAXIMUM OF 15 BAR. A
HIGHER PRESSURE CAN CAUSE DAMAGE TO THE TRACTOR'S MOTOR.
ADJUSTMENT
The fan's rpm is adjusted by regulating the tractor control unit.
The fan's turning speed must be adjusted to 4200 rpm or to 4500 rpm as
shown in table above.
IF OIL IS OVERHEATED DUE TO AN EXCESSIVE FLOW OR DUE TO LOW OIL
SUPPLY, THEN AN ADDITIONAL OIL TANK WILL BE REQUIRED.
IF THE FLOW OF THE TRACTOR'S HYDRAULIC PUMP IS NOT HIGH ENOUGH
IT WILL NOT BE ABLE TO POWER THE FAN'S MOTOR OR ACTIVATE THE
OTHER ELEMENTS REQUIRED. IN THIS CASE AUXILIARY EQUIPMENT CON-
SISTING OF A HYDRAULIC PUMP FITTED ON THE TRACTOR'S UNIVERSAL
JOINT SHAFT THAT DRIVES THE FAN'S HYDRAULIC MOTOR AS WELL AS A
