To change the pressure, turn the adjustment wheel clockwise with an Allen key to increase the pressure and anti-clockwise to
decrease it.
The working range is between 0 and 40 bar.
Reduce the pressure if conditions are too wet or on loose soil (e.g. on tilled soil before seeding).
- Increase the pressure in dry conditions if the seeding unit has difficulty penetrating the soil and if any irregularity in the depth
of seed placement is noticed.
NOTE
Do not work with excessive depth control pressure. Too much pressure not only accelerates the mechanical
wear of the seeding unit unnecessarily, it can also have a detrimental effect on the quality of the seed (excessive
compaction when closing the furrow).
6.3 Turbine setting
The turbine has a maximum speed of 4,500 rpm; exceeding this can damage the engine.
To switch on the turbine, engage the corresponding hydraulic valve and set it to the continuous pumping position.
Then adjust the hydraulic flow of the valve to adjust the speed of the turbine.
The speed of the turbine must be adjusted depending on the seeds. There is no settings table because the setting will depend
on the type of product and the doses used.
The usual operating range is between 2,500 and 4,000 rpm. To select the correct speed, ensure that there is no grain
accumulation in the two transparent feed pipes of the distributor heads. Smaller seeds require less air to be transported.
NOTE:
Insufficient flow can lead to build-up in the pipes and cause blockages.
Large seeds require more airflow than small ones.
6.4 Debris catcher setting (optional)
1. Connect the 3-pin plug to the air compressor.
2. Adjust the pneumatic switch to reach the desired pressure on the pneumatic box.
NOTE:
Too much pressure on the debris catcher leads to soil overload.
