come loose or the ejector elbows are not in the correct
positions.

- Check whether the hydraulic hoses are correctly con-
nected and that the hydraulic connector is pressurized.
- Check the programming of the Control Station.

tractor (130 bars and at least 35 l/min.)? Has the flow
valve of the tractor been correctly set?
- Has the fan speed regulator been correctly set? (Op-
tional; this is used when the tractor does not feature an
inherent flow regulator device.)
