Replacement of tool

Tool is deformed of burrs produced in a long-term use. When a tool tip is worn out, tool is liable to slip.Then, sharpen the tool tip. Grinding the tool tip many times to sharpen the edge, however, it will make a heat-treated hardened surface layer disappear and it will wear out the tool rapidly. In this case, replae with a new tool. If a gap between tool and front cover ring becomes large, piston fails to fit in tool resulting in damage. When the gap is found in over 9mm, replace thrust ring together with the tool.
