Product: "Crimpzange 5 interchangeable inserts", ca 17 No instructions included, in some missions there is no previous experience is not possible to know for which Krimpstecker they are. The pressure is often too low, even taking the set screw to maximum. You have to live with some Fehlkrimpen. Committee inevitable. Nothing Krimpen fast for me, because it usually is not attached right away but rausflutscht again at drawing under wobbling. The fifth crimp stops finally.
