Before using the riveting machine and to facilitate the
extraction of self-piercing rivets, it is possible to make
a mark on the rivet with the center punch tool (ref :
048379) to locate the extraction tool in the mark.
If during the extraction, the rivet stay in the matrix
hole, breathe out to get it out before making another
extraction.
