1. Never touch the surface of the ITB surface with bare hands.

  2. The PTR unit must be removed before the ITB unit.

    • If the ITB unit is removed with the PTR unit in the drawer, the edge of the ITB unit will scour and ruin the surface of the PTR below when the ITB unit is pulled from the machine. This can permanently damage the PTR.

  3. Pull the ITB unit out of the machine only when it is absolutely necessary.
  4. Always work carefully around the ITB (to avoid dropping tools, screws, etc.) when it is pulled out of the machine.
  5. Before installing a new ITB, clean all the rollers and the inner surface of the ITB unit with a dry cloth to prevent the new belt from slipping.
