How to safely intervene on a stuck rivet mandrel.

A stuck mandrel is one of the most frustrating issues when working with blind rivets: it slows down production and, if handled improperly, can damage the tool. The main causes are often incorrect nosepieces, poor maintenance, or improper adjustments. To intervene safely:

•        Avoid forcing the trigger excessively, as this may damage the internal jaws.

•        Follow the manufacturer’s recommended release procedure, disassembling and cleaning the affected parts.

Regular tool maintenance and checking accessories significantly reduce the frequency of jams and help maintain consistent fastening quality.
