  • Page 8: Changing Abrasives

    DESCO Innovative Solutions 4. Changing Abrasives Changing abrasives is a simple procedure as described below. However, when you change abrasive type, additional setup is often required. For example, if you change from coated abrasives to conditioning discs, you will also need to change the backup pad and shaft extension.
  • Page 9: Abrasive Depth Within Dust Collector

    Figure 5.1 – Abrasive Depth NOTE: If your abrasive depth is not within the acceptable range as identified in Figure 5.1, contact your Desco representative for assistance. Abrasive Depth – Adjusting to Accommodate Variable Thickness Abrasives discs and the backup pads which secure them vary in thickness. As a result, the depth within the dust shroud varies and this affects dust containment.
