Clean and/or remove an irregular or broken pipe to create an even surface for the Parana to start the removal of the remaining plastic fitting shoulder.
If the pipe is surrounded by cement to the edge of the pipe, remove the cement to allow the cutting blades to spin free without touching the concrete. One inch of relief is enough space.
Make sure the inside of the pipe is not oval or has glue streaks inside to impede the guides. If the pipe is oval, the Parana will not work. Remove any obstruction before drilling.
Check guide clearance in depth, remove bottom guide if necessary.
Insert tool into pipe, making sure cutter teeth are in contact with the material to be removed.
Start the drilling process with the drill on low speed. Use caution at all times.
Gauge drilling pressure exerted on tool as not to create too much heat.
Periodically stop the operation to let pipe cool, remove shavings, and inspect uniformity of the removal operation. Adjust angle and pressure if necessary.
When the Parana has finished the removal process, the tool will “fall” or “bottom out”.
Clean up shavings and replace Parana in protective case. Pipe will be ready to re-glue or reuse. Collect the money or go fishing with the time saved using the Parana.
