Protecting the spraying equipment against frost

IMPORTANT
Risk of machine damage due to frost
Observe the following instructions.
  1. Unfold the boom, Unfolding the boom.
  2. Perform an intensive cleaning, .
  3. Empty the flushing water tank.
  4. Run the spray liquid pump.
  5. Couple the suction hose on the suction connection. Place the other end of the suction hose in a container with antifreeze.
  1. Select the function on the TwinTerminal and confirm.
  1. Set pressure valve chest DA to the position.
  1. Fill at least 100l of propylene glycol based antifreeze into the flushing water tank.
  2. Select the function on the TwinTerminal and confirm.
  3. Set pressure valve chest DA to the position.

The antifreeze will be pumped into the spray liquid tank.

  1. Select the function on the TwinTerminal and confirm.

The antifreeze will be pumped into the liquid circuit.

  1. Set pressure valve chest DA to the position. Wait for 30 seconds.
  2. Set pressure valve chest DA to the position. Spray antifreeze into the induction bowl for 30 seconds using the spray lance of the external wash-down device.
  3. Set pressure valve chest DA to the position.
  1. Set switch tap IJ to the position.
  2. Set switch tap QU to the position.

  1. To ensure that antifreeze is distributed into all of the lines:

    On the induction bowl, move switch taps EA and EB into every position consecutively and activate each of the corresponding functions for 10 seconds.
  1. Set pressure valve chest DA to the position. Briefly run the agitator at maximum intensity and then switch it off.
  2. Select the function on the TwinTerminal.

High-pressure cleaning of the spray liquid tank will be activated.

  1. If the machine is equipped with HighFlow+:

    Set the HighFlow+ switch tap to the position.
  2. Select the function on the TwinTerminal and confirm.
  3. Start the spraying procedure on the ISOBUS control terminal and wait until antifreeze emerges from the nozzles.
  4. Switch the part-width section control on and off several times

or

With AmaSelect: switch through all nozzle positions.

  1. Switch the boundary nozzles and edge nozzles.
  2. Place a collection bucket under the emptying connection and collect some of the liquid.
  3. Check liquid in the collection bucket for adequate water to antifreeze ratio.

  4. If there is not enough antifreeze:

    Add more antifreeze and repeat the procedure.
  1. Activate the vent valve of the suction filter 1 for 20 seconds.

The suction filter will be suctioned empty.

  1. Set stop tap DE to the position.

The pressure filter will be drained.

  1. When spray liquid no longer flows out:

    Close stop tap DE.

  1. If the machine is equipped with line filters:

    Drain all line filters with the stop tap 1.
  2. Close the stop taps for the line filters.

If the machine is equipped with HighFlow+, the HighFlow+ pressure filter 2 must also be cleaned.

  1. Place a collection bucket under the drain hose in front of the right rear wheel.
  2. Set the HighFlow+ switch tap 1 to the position.
  3. Drain the liquid until the HighFlow+ pressure filter is drained.
  4. Unscrew the HighFlow+ pressure filter, clean it and screw it back in.
  5. Place the HighFlow+ switch tap back in its initial position.

If the machine is equipped with the pressure connection with automatic fill stop, the filling device must be drained.

  1. Take the sealing cap off of the pressure connection.
  2. Start the pressure filling of the spray liquid tank on the TwinTerminal.
  3. Wait until no more water emerges from the pressure connection.
  4. Stop the pressure filling on the TwinTerminal. Relieve the pressure.
  5. Start the pressure filling of the flushing water tank on the TwinTerminal.
  6. Wait until no more water emerges from the pressure connection.
  7. Stop the pressure filling on the TwinTerminal. Relieve the pressure.
  8. Put the sealing cap on the pressure connection.
  1. Remove the adapter from the pressure sensor on the Super-L boom.
  2. Drain the pressure sensor.
  3. Install the adapter.
  1. Remove the adapter from the pressure sensor on the right agitator under the cover.
  2. Drain the pressure sensor.
  3. Install the adapter.
  1. Remove the pressure sensor for the flushing water tank underneath the flushing water tank.
  2. Drain the pressure sensor.
  3. Install the pressure sensor.
  1. Reuse the mixture of antifreeze and spray liquid

or

Dispose of the mixture correctly.

  1. Empty the hand wash unit. Leave stop tap HW open.
