Operation:
The fan is designed to be driven at 1000 rpm via the PTO shaft of the tractor. The upper alarm
limit of the control box has been preset at a fan speed of 4800 rpm, which is reached at 1100 rpm
on the PTO. The maximum allowable fan speed is 6000 rpm.
Depress the button 18 until the fan speed is displayed on the control box.
The fan alarm of the control box has been factory preset to a minimum speed of 3800 rpm and a
maximum speed of 4800 rpm. The alarm limits can be adjusted in the control box. For more in-
formation, see ”3.16.3 Programming the Type III Control Box” on page 54.
NOTE!
During operation, the oil temperature may become very high (above 80
o
C)!
Before starting:
! Check that no cables or bolts are loose.
! Check that the oil level is in the upper half of the inspection window.
! Check that the pump is securely mounted and that the pump mount is secure.
! Check that all hoses are free from damage and properly suspended.
Normal start-up:
Always start the pump with the tractor at idle and let it run for a while to allow all hoses, the pump
and motor to warm up. Do not start the fan while the tractor is at operating speed. In this case cold,
viscous oil and pressure peaks will shorten the service life of the system.
