2. DESCRIPTION
Each die assembly consists of an upper die (crimper)
and a lower die (anvil), a retaining screw (on the upper
die), and a hex wrench for securing the lower die to
the platform of the hand tool frame.
The die assemblies are identified by part numbers,
color dot codes, and applicable wire range
designations. See Figure 1. The 90390-3 die
assembly has a red color dot on both the crimper and
2. Position the upper die in upper die platform of
the tool. Thread the die retaining screw through
the mounting hole in the top of tool and tighten
the screw until it is snug but NOT secured.
3. While guiding the upper die into alignment with
the lower die, slowly close the tool handles until
the dies bottom.
4. Tighten the upper die retaining screw until the
