1. INTRODUCTION
Platform Crimping Die Assemblies 90390-3 and
90391-3 are used in Platform Hand Tool Frame
58078-3 (408-6976). The die assemblies crimp the
Ultra-Fast Fully Insulated FASTON* Terminals listed in
Figure 2. Read These instructions before using the
Platform Hand Tool Frame and Platform Crimping

REVISION SUMMARY.
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

crimping.
3. INSTALLATION
Determine the part number of the terminal you are
crimping, then refer to the table in Figure 2 and select
the appropriate die assembly. Install dies as described
below.
3.1. Installing Lower Die Assembly
3.2. Installing Upper Die Assembly
1. Squeeze the tool handlers together until they
bottom. Then allow them to open fully.
2. Hold the hand tool frame so that the back of
the tool is facing you and note the socket head
screw located in the lower die platform. See
Figure 3.
3. Slide the lower die onto the lower platform,
ensuring that the drilled holes on the side of the
lower die line up with the socket head screw.
4. With the lower die in place, turn the socket
head screw (on the die platform) clockwise until
snug. Do NOT overtighten.
1. Remove the die retaining screw from the die
assembly.
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
die is secure.
5. Squeeze the tool handles together until the
ratchet releases. Allow the tool handles to open
fully. The tool is now ready for use.
NOTE
i
If the lower die will not seat on the lower die
platform with the drilled hole aligned with the socket
head screw, use the hex wrench to turn the screw
either in or out until the set screw does not protrude
from either side of the lower tool jaw.
