I have been using this now for a couple of cheers to crimp JST pins onto ribbon cables, I love the JST connectors but I really do not like crimping them.
There's a definite "knack" to using this tool, and even having crimped thousands of these, I still find them very fiddly to crimp.
The JST crimps have 2 tab sections, one is used to crimp to the insulator ensuring that the cable is held in place, and the second is the actual terminal itself.
The method that works for me is:
1.) bend the insulator tabs inwards very slightly with needle nosed pliers, if you don't do this, you won't be cable to perform the actual crimp.
2) place the crimp into this tool, I rotate the tool in my hand so the legend is facing away, I need to do this is ensure that I'm only crimping the insulator and not the other tabs, I gently close the tool slightly to grab the crimp, then rotate the tool back so the legend is visible, the back of the connector is now facing me.
3.) As I'm looking at the rear of the crimp, I insert t he cable into the crimp and look at the other side to make sure that I haven't pushed the cable in too far or not enough, it should be positioned so that the cable insulator is touching the outer tab, and the conductor is touching the inner tabs.
4.) very carefully I close the tool to perform the crimp.
At this point, you might get a good crimp, or, you might end up with the crimp rotating in the tool jaws, in which case you have to reset everything and try again, the final problem you may get is that the tabs just didn't fold properly, in which case you need to remove the crimp/cut it off/trim the cable and so on.
If the crimp was OK, then you repeat the process again, and crimp the inner tabs, just make sure that you check that you are not crushing the end of the crimp, if you do the pin won't be usable.
Other issues also include the crimp bending.
It works reasonably well most of the time, but sometimes they can be infuriating, especially when the tabs don't fold properly.
This is a common issue I've read with this tool, but this is one of the best tools for these crimps, so I kind of just live with these issues.
Take your time, and inspect everything before you make the actual crimp.
It's also well worth having a multimeter set to "beep" mode, after crimping you should check that the cable is ok, sometimes the cable may more and the conductor might make no or poor contact.
