Using the socket/pivot pin and the flare tool, trim the damaged thread. The correct milling depth has been reached when the shoulder of the tool (B) rests on the base material. It must be ensured that the milling tool does not jam in the hole.

Place the tapping tool on a socket with a turning pin and cut the thread. Blow out chips and completely degrease newly cut thread.

Screw the socket screw of the socket set tool firmly into place with the angle screwdriver of the hexagon socket and screw the socket onto the big-INSERT sockets of the set tool. In the process, the sealing compound (G) must be applied in the upper area around the liner shoulder. The liner screwed onto the setting tool (D) and provided with sealing compound must be screwed into the precut thread with the hexagon socket. Release the socket set tool by turning the angle screwdriver with an Allen key to the left. Then screw the setting tool out of the liner with the corresponding socket.

Place the turning tool on the socket/turning pin. Screw the screw-in tool into the liner. Pressing in is completed when the screw-in tool can suddenly be turned further more easily – the screw-in tool can be turned back. The repair is ended.
