Instructions for Use
1. Check the pipe size and SDR in order to select the correct Mandrel.
2. Unscrew the shaft thumbscrew by turning anticlockwise. It is not
necessary to fully remove this from the tool.
3. Use the shaft locator to locate the shaft at the correct position for
the pipe being used by lining up the line on the side of the shaft
locator with the size markings on the body of the tool then tighten
the shaft thumbscrew clockwise.
4. Ensure the arm spring clip is keeping the arm of the tool in its
uppermost position. If it is not, press on the rear of the arm with the
thumb and move the clip to keep the arm in its uppermost position.
5. Insert the mandrel shaft into the selected mandrel.
6. Insert the mandrel fully into the pipe to be scraped.
7. Turn the whole tool clockwise until the cutting tip is over the edge
of the pipe. Ensure it is on the edge to ensure there are no areas of
un-scraped pipe.
8. Push down on the rear of the arm and release the spring clip to
allow the cutting tip to rest on the pipe.
