  • Page 32: Sweeping Brush Angle

    AG Duo Operation Manual 4.3.4 SWEEPING BRUSH ANGLE To ensure that the brush sweeps old bedding away from the cubicles, only the front of the brush should be in contact with the cubicle surface. This can be achieved by adjusting the brush head using two adjustments. This adjustment may be necessary if the height setting has been changed.

  • Page 33: Fault Conditions & Recovery

    If, during the dispensing of the bedding product, the auger or conveyor stalls, follow the procedure below: 1. Bring the AG Duo to a stop and isolate the machine, ensuring that the isolator switch is removed (see Section 1.2.5). 2. Apply the parking brake (see Section 1.2.6).
