Setting The Auto Height Control – Spider Series

1. Activate the Auto Height Control (AHC) function on the boom mower and lower the attachment tool to the ground using the joystick. Then press the button for the AHC-function on the control panel.

2. Always first ensure that the potentiometer on the control panel is turned to the “0” position.

3. With the potentiometer in the “0” position, slowly turn upwards until the attachment tool leaves the ground.

4. Then turn the potentiometer down a little again, until the attachment tool begins to sink slowly.
