DESCRIPTION
The tool frame features two jaws, a handle, a ratchet adjustment wheel, and an emergency ratchet release.
The die set consists of a crimper (upper die) and an anvil (lower die). The tool frame holds a die assembly with
one or more crimping chambers (see Figure 1). Die retaining pins and die retaining screws are used to 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 does 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.
CAUTION
The dies bottom before the ratchet release. This feature ensures maximum tensile performance of the crimp.
Do not
re-adjust
the ratchet unless you have verified that the crimp height is incorrect (see section 7, ADJUSTING THE RATCHET).
