e)
Hold the sequence of buttons for 8 seconds until both the 'bale chamber milling direction' and 'on' LED's
illuminate.
f)
Release buttons and the LED's should flash alternately.
g)
Using the automatic bale chamber speed control button to slow down,
and the manual bale chamber speed control button to speed up,
h)
slow the bale chamber down to the point where it just stops.
i)
Press the 'off' button to save the slow speed.
You have now programmed the electronic controls for the minimum bale chamber rotation speed.
To programme the electronic controls for the maximum speed repeat the same process again BUT Step c should
have the speed dial set to 10 and in Step g you should increase the bale chamber speed to the maximum
desired.
Important, the oil flow for the conveyor motor is prioritised over the oil flow to the motor rotating the bale
chamber. The speed of the conveyor should remain constant if oil flow to the valve is reduced, as the pump
supplying the oil to the valve is driven from the milling rotor driveline it is important the calibration is undertaken at
full working PTO speed.
The speed of the conveyor can be changed using the thumb screw on the valve block.
General Discharging Instructions
The speed of rotation of the bale chamber will control the feed rate of the machine, higher rotational speeds will
result in higher processing speeds and consequently higher power requirements. The speed of the bale chamber
is controlled by setting the speed dial on the control desk.
When milling large rectangular bales maximum throughput is achieved if the bale chamber is kept no less than half
full of material. The best results are achieved if part bales are loaded into the bale chamber.
Large round bales can be placed in the tub on end or on their side. To work out which is the best method for the
material being chopped try bales in each orientation.
Avoid dropping a complete round bale into the bale chamber from a high level to prevent shock loading to the mill
rotor and driveline.
Ease the bale over the edge of the bale chamber and lower into the tub as gently as possible.
The evenness of feed and power consumption will vary with the condition of the bale. In general, damp or caked
straw materials will require a higher power input than dry brittle materials. Bales with a moisture content greater
than 20% will result in higher power requirements and take longer to process & could result in blockages.
The speed of the mill rotor is monitored by the electronics, if the mill rotor requires more power than the tractor
driving the machine is able to deliver then, as the rotor speed drops it will reduce or stop the rotation of the bale
chamber automatically. Once the mill rotor returns to the operating speed then the rotation of the drum will restart
and gradually return to the rotation speed set by the control desk.
The sensitivity of the automatic bale chamber speed control can be altered using the three modes on the control
desk. This allows the power requirement of the machine to be varied according to the power available from the
tractor.
The mode is switched by repeatedly pressing the automatic bale chamber control button.

However the optimum setting will vary depending on material moisture content and density.
As the milled material builds up beneath the conveyor discharge point it may be necessary to stop milling and
reposition the machine if the material can not be moved away by the loading vehicle.
