Review on 🎁 Enhance Efficiency with Amjoy Handles Labor Saving Mandrels - Perfect for Gifting! by Jared Winebrenner

See photo. Caliber is in millimeters. It will show you the progress of the tool as you close the handles. The breaking zone of the supplied nuts is 5-6 mm. You measure the mm of metal you are installing the nuts in and subtract that from the 5-6mm break zone. Let's assume there are 3 mm left. You then loosen the round thumb ring that holds the nose in place and adjust the nose up or down until you have 3-4mm of travel. No longer. The movement is determined by the maximally extended handles. Throw away the instructions, NO element of this tool needs to be reinserted. Especially the mandrel, which is impossible anyway because it has to fit into a spring-loaded retaining ring. Now after assembly install the rivet nuts but please if you feel a pinch zone and you do it and it then tightens again don't insist on closing the handles to the end but check first if it's stuck and you're happy, go no further. Set the tool back to a slightly smaller stroke, check again and if everything is fine at full stroke you can do 100 an hour.
