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
CAUTION
feature ensures maximum tensile performance of
the crimp. DO NOT re-adjust the ratchet.
3. INSTALLATION AND REMOVAL OF DIE SET
AND LOCATOR ASSEMBLY (Figure 1)
1. Open the tool handles and remove the two die
retaining screws from the tool jaws.
2. Place the wire anvil and insulation anvil so that
