2. FOLDING AND UNFOLDING
UNFOLDING
1. Ensure machine is fully raised.
2. Remove the transport strap from the rear wing cylinders.
3. Open the taps on the drawbar cylinders.
4. Ensure that the parking stands are in the fully raised position.
WARNING: FAILURE TO STOW THE PARKING STANDS BEFORE
THE PRESS IS UNFOLDED WILL RESULT IN SERIOUS DAMAGE TO
THE MACHINE.
5. Operate the hydraulics to fully unfold the wings.
6. Check the wing pressure on the gauge. If this is above or below the desired value then
pressurise the wings to fold which will zero the setting. Increase the pressure on the
cylinder side by adjusting the handwheel clockwise. By rotating anticlockwise the
pressure will be reduced (see Adjust The System Pressure for more details). Pressurise to
unfold until the required pressure is achieved.
7. Lower the machine to the ground until the chassis is level front to rear or the drawbar
cylinders touch the depth stops.
FOLDING
1. Raise the machine onto the transport wheels.
2. Operate the hydraulics to fully fold the wings.
3. Fit the transport strap across the pins on the rear wing cylinders for transport safety.
4. Close the taps on the drawbar cylinders.
5. Lower the parking stands if the press is to be unhitched from the tractor in the folded
position.
