Insert the end of the cable into the round cable stripper opening. Close the 2 sides of the crimper with the Vise-Grip pliers.
Hit the crimper with a hammer against a wood block until both sides of the crimper meet. Pull off the cable insulation that has been cut.
Fold the exposed wire strands over the cable insulation.
Insert the terminal over them.
Set the terminal into the hexagonal form on the crimper.
Put the top and hit it hard with the hammer!
The terminal is now hexagonal, you have done it like a “pro”.
