Suction or Pressure Gate. If the Pallets are rubbing on the surface of the gates it will result in damage to the Pallets and
either the Suction or Pressure Gate. This damage will result in possible metal contamination of the product and will reduce
the life of the parts.
Inspect the Gates and Drive Hubs for burrs, remove burrs if any are found.
This Rear Drive Hub adjustment must be performed daily. The following factors is why this adjustment will vary daily.

Check the gap (See the detail above) The gap should be between 1 and 1.5 mm
-
If the gap is below 1mm the knife will not cut correctly
-
If the gap is greater than 1.5mm the knife will be too tight and the knife will heat up and cause the edges to chip off.
This will result in metal contamination of the product -
Make the adjustment by removing or adding additional White Plastic Spacers. Spacers are available in 1, 2 and 3mm
