The Model 747 is a dry process disc repair machine, meaning it does not use a liquid (like water) to cool or lubricate. Instead it uses a specially formulated polishing compound in combination with Low Friction Rotation to quickly remove fingerprints to light abrasions from any disc. In the Low Friction Rotation process the polishing pad and the disc rotate in opposite directions (counter-clockwise and clockwise), which creates a lower level of friction compared to the Model 1600. This process is very safe, and perfect for dry-type machines to minimize the heat produced during repairs. Low Friction Rotation is capable of removing light to medium scratches quickly and efficiently.

Tips & Pointers
If scratches remain on the disc after polishing, verify they are not top side scratches or foil dents. For more information on this subject, please refer to the section “Identifying Scratches”. When repairing black or dark discs such as PlayStation games, light repair marks may be visible on the disc surface after using the Stage 2 head. These marks should be consistent and should be removed by Stage 1 polishing. If there are scratches that still remain, simply repeat the repair process. If there are deep scratches in the disc that seem to be too stubborn to remove, and they are not top side scratches or foil dents, these will need to be repaired with a wet micro-abrasive type machine such as the Azuradisc Model 1600. Using a dirty or regular cotton cloth may re-scratch discs. For the best results use a clean Azuradisc super soft micro-fiber wiping cloth. All polish marks should disappear entirely. However, if there are still hairline scratches from the last polish pattern repeat the process.
