Apprentice question
Field check
Standard work. Do it right, keep moving.
Shallow pumping causes the tool's internal hardened steel teeth to grip the rivet mandrel at unequal points, slipping and jamming the pulling core. Open the tool handles completely wide to reset the internal jaw teeth, slide the rivet stem completely home.
["You are fastening an internal structural reinforcing angle bar to a 48 × 24 trunk line. You use a manual pop-rivet gun, but you pump the handles in shallow, half-inch quick squeezes. The steel mandrel stem snaps off off-center, jamming the tool's internal grip jaws solid.", "Shallow pumping causes the tool's internal hardened steel teeth to grip the rivet mandrel at unequal points, slipping and jamming the pulling core. Open the tool handles completely wide to reset the internal jaw teeth, slide the rivet stem completely home. The likely recovery is to check the tool setup, correct the prep or technique if it is within your assignment, and bring the journeyman or foreman clean information before the work creates rework overhead."]
