2. DESCRIPTION

The tool frame features two jaws, a handle, ratchet

adjustment wheel, and an emergency ratchet release.

The die set consists of an indenter (upper die) and an

anvil (lower die). The tool frame holds a die assembly

with two crimping chambers. See Figure 1. Die

retaining pins and die retaining screws are used to

position and secure the dies in the tool frame.

The tool features a ratchet and an adjustment wheel

with a range of settings. The ratchet ensures that the

tool has completed the cycle and will not release until

the handles have been FULLY closed, unless the

emergency ratchet release is rotated to manually

release the ratchet. The adjustment wheel controls

the amount of handle pressure exerted on the dies

during the crimping procedure.

The dies bottom before the ratchet releases. This

feature ensures maximum tensile performance of

the crimp. DO NOT re--adjust the ratchet.

3. INSTALLATION AND REMOVAL OF DIE SET

1. Open the tool handles and remove the two die

retaining screws from the tool jaws.
