Activating FILTER BOOST in cab Category 4

When the machine is equipped with a Category 4 cab, the fan speed can be increased with the FILTER BOOST function to help maintain the required cab pressure under unfavourable weather conditions.

In normal operation, the maximum fan speed is 85% of the possible speed. The maximum fan speed with FILTER BOOST is 100% of the possible speed.

  1. Press the button 2.
  2. In the menu, activate the FILTER BOOST function.

The fan sound becomes louder.

The display shows the currently set fan speed 1 in a bar diagram. When the bar diagram is 100% filled, the maximum possible fan speed has been reached.

NOTE

When the machine is switched off, FILTER BOOST is deactivated.
