Operating Instructions
Attachment
On delivery the roller is in transport position. At start-up the roller is attached to the tractor.
Important:
Check that the towing hook height is between
500 and 550 mm.
ontrollér at trækkrogshøjden er mellem 400 og
500 mm.
Raise the support leg and place it in the transport fittings on top of the drawbar. Now fit all the
hydraulic hoses.
The roller requires two double-acting hydraulic outlets.
The hoses for the tip cylinder are provided with red cable straps.
The hoses for the wing cylinder are provided with blue cable straps.
The hoses for the long finger harrow are provided with green straps (extra equipment).
Power plug and control box for weight transfer protection are putted into the cabin (8.2m models)
Unfolding and folding of the machine
1. Check that the male quick couplings mounted from the factory fit the tractor's female quick
couplings.
2. Contact on the control box for weight transfer protection activated (diode lights up)
3. Now pressurise the tip-cylinder (red), so that the side sections are lifted free of the transport
cradle.
4. Then the wing-cylinders are pressured (blue), so that the side sections are folded out as much
as possible, the hydraulic rams being fully closed.
5. Now relieve the pressure of the tip-cylinder (red), and the roller will tip forward, down to
working position. When the bottom has been reached, let go of the hydraulic handle.
6. Contact on the control box for weight transfer protection de-activated (diode off)
7. Now the wing-cylinders are pressured (blue), so that the side sections are pressed down
against the ground and the manometer is showing the hydraulic pressure according to the
schedule on the next page in order to obtain the correct weight transfer between the middle
section and the side sections.
Change-over from working to transport position
8. Contact on the control box for weight transfer protection activated (diode lights up)
9. First the side sections are lifted free of the ground by pressurising the wing-cylinders (blue).
10. The roller is tipped completely backwards and is locked by pressurising the tip-cylinder (red).
11. Now pressurise the wing-cylinders (blue), so that the side sections are turning forwards,
towards the stop on the transport fittings of the drawbar.
12. When both side sections are parallel with the drawbar, they are lowered down into the
transport cradle by relieving the tip-cylinder (red). This is to be performed with care.
13. Contact on the control box for weight transfer protection de-activated (diode off)
Important: You must not pressurise any cylinders in transport position.
14. All hydraulic hoses are relieved, and the machine is ready for transport.
