Setting the tripping force for the central overload safety

REQUIREMENTS

  • The implement is coupled.

  • Blue hydraulic connection is coupled.

WARNING
Risk of accident due to the plough bodies with overload safety falling down
When you depressurise the hydraulic overload safety, the plough bodies fall out of their mount.
Select a preload of at least 100bar for the overload safety.
Always maintain pressure on the overload safety.
  1. Ensure that all hydraulic accumulators on the plough bodies are opened in position 1.
  1. Move the switch tap for the running gear to position 0.
  2. Move the switch tap for the overload safety to position 1.

  3. To set the tripping force of the overload safety simultaneously for all plough bodies:

    Actuate the blue tractor control unit.
  4. Select preload between 100 bar and 200bar.

Default value: 120bar.

  1. Move the switch tap for the overload safety to position 0.
NOTE

To increase operational reliability, the hydraulic accumulator on each coulter body can be closed with the hand lever. Central adjustment of the preload is no longer possible.

By closing individual hydraulic accumulators, the tripping force can be adjusted differently on the coulter bodies.

Preload individual closed hydraulic accumulators with a maximum of 170bar.

The hand lever is in the transport box.
