(Instruction Shee

). The die assemblies crimp the Ultra-Fast Fully Insulated FASTON* Terminals

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 the anvil, while the 
90391-3 die assembly has a blue color dot on the crimper and the anvil. The color coding on the die assembly 
corresponds to the color coding on the translucent insulation of the Ultra-Fast FASTON terminal for easier 
identification when crimping. 

 

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. 

 

 

PROPER USE GUIDELINES 

Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use and low 
volume applications. A wide selection of powered application equipment for extended-use, production operations is available.
