Performing quick cleaning or intensive cleaning

Perform the cleaning of the spray liquid circuit, the spray lines and the nozzles while driving on the field, since cleaning water is applied intermittently. The machine can be cleaned in the farmyard if a collecting facility is available, e.g. a Biobed.

A distinction is made between quick cleaning and intensive cleaning:

  • Quick cleaning must be performed daily. Duration: approx. 4 to 6 minutes.

  • Intensive cleaning must be performed before a critical agent change or before the machine will be taken out of service for a longer period of time. Duration: approx. 15 minutes.

REQUIREMENTS

  • Flushing water tank is filled.

  • Spray liquid tank is empty.

  1. Run the spray liquid pump on the ISOBUS control terminal.
  2. Select Cleaning > Intensive cleaning in the Field menu on the ISOBUS control terminal

or

Select Cleaning > Quick cleaning in the Field menu on the ISOBUS control terminal.

The ISOBUS control terminal shows the conditions that must be met:

  • Maximum fill level of the spray liquid tank

  • Minimum fill level of the flushing water tank

  • Boom unfolded

  • Speed of the spray liquid pump

  1. Ensure that the conditions shown on the ISOBUS control terminal are met.
  2. Start the cleaning procedure.
  3. Enter the quantity of flushing water required for cleaning.

The agitator will be flushed.

The tank internal cleaning will be switched on.

  1. Confirm and start driving at the same time.

The cleaning water will be sprayed out. The spraying procedure will be started and stopped several times.

During intensive cleaning, cleaning water is sprayed out automatically three times.

NOTE
If the machine is equipped with AmaSelect single-nozzle control, the nozzles are automatically switched during the cleaning procedure. This ensures that all of the nozzles are flushed.
  1. Unscrew the cap 2 with the suction filter 1.
  2. Take out the suction filter.
  3. Clean the suction filter with water.
  4. Grease the O-rings.
  5. Screw in the cap with the suction filter.
  1. Unscrew the cap 2 with the pressure filter 1.
  2. Take out the pressure filter.
  3. Clean the pressure filter with water.
  4. Grease the O-rings.
  5. Screw in the cap with the pressure filter.
  6. Randomly check several nozzle filters on the boom for spray liquid residues.

  7. If there are spray liquid residues in the nozzle filters:

    Take out all of the nozzle filters and flush them with water.
  8. Reinsert the nozzle filters.

If the machine is equipped with line filters, the line filters must also be cleaned.

  1. Drain all line filters with the stop tap 1.
  2. Take off all line filters.
  3. Clean all line filters with water.
  4. Grease the O-rings.
  5. Reinsert all line filters.
  1. Place a collection bucket under the emptying connection.
  2. Switch off the spray liquid pump on the TwinTerminal.
  3. Select on the pressure valve chest DA.
  4. Open the RM stop tap and empty the residual quantity into the collection bucket.

  5. To stop the residual emptying:

    Close the RM stop tap.
  6. Select on the pressure valve chest DA.

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. Select on the HighFlow+ switch tap 1.
  3. Drain the liquid until the HighFlow+ pressure filter is drained.
  4. Unscrew the HighFlow+-pressure filter.
  5. Clean the HighFlow+ pressure filter with water.
  6. Grease the O-rings.
  7. Screw the HighFlow+ pressure filter back in.
  8. Place the switch tap of the HighFlow+ pressure filter back in its previous position.
