Page 15: Mounting And Replacement Of Tools
Remember that the grinding tools can be extremely hot if grinding work has recently been carried out. The HTC 500 is equipped with our newly patented and copyright protected EZchange™ tool system. It consists of wings with diamond tools. These wings are folded and pushed into a tool holder where they are locked using a light blow from a non-rebounding rubber hammer.
