CRIMPING PROCEDURE
Select the appropriate wire size and terminal for the die assembly. The wire size and insulation diameter must
be within a specified range for the terminal. Strip the wire to the appropriate length shown in Figure 4. Do NOT
cut or nick the wire strands. Then, proceed as follows:
1. Hold tool frame so that the FRONT side is facing you and open crimping dies by squeezing tool frame
handles together until ratchet releases.
2. The locator stop must be adjusted to accommodate the terminal series size, which is marked on the
terminal insulation (.187 or .250). Rotate the blue plastic locator stop until the series size number,
appearing in the uppermost position, matches the terminal series size. Refer to Figure 4.
