2. DESCRIPTION (Figures 1 and 2)
The tool features a tool frame with a stationary jaw
and handle, a moving jaw, a moving handle, and an
adjustable ratchet that ensures full contact crimping.
The tool frame holds a die assembly with four
crimping sections.
The die assembly features a wire anvil, an insulation
anvil, a wire crimper, and an insulation crimper.
Attached to the outside of the tool frame is a locator
assembly, which contains a locator, a spring retainer,
and a contact support.
Die retaining pins and die retaining screws are used
to position and secure the dies in the tool frame. A
nut is used on the long die retaining screw to hold the
locator assembly in place.
3. INSTALLATION AND REMOVAL OF DIE SET
AND LOCATOR ASSEMBLY (Figure 2)
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
their chamfered sides and their marked surfaces
face outward, when mounted in the moving jaw of
the tool frame.
3. Insert the two die retaining pins.
4. Insert the short die retaining screw through the
jaw and through both anvil dies, and tighten the
screw just enough to hold the dies in place. Do not
tighten the screw completely at this time.
5. Place the wire crimper and insulation crimper so
that their chamfered sides and their marked
surfaces face outward, when mounted in the
stationary jaw of the tool frame.
6. Insert the two die retaining pins.
7. Insert the long die retaining screw through the
jaw and through both crimper dies, and tighten the
screw just enough to hold the dies in place. Do not
tighten the screw completely at this time.
8. Carefully close the tool handles, making sure
that the anvils and crimpers align properly.
Continue closing the tool handles until the ratchet
in the tool frame has engaged sufficiently to hold
the anvils and crimpers in place, then tighten both
die retaining screws.
9. Place the locator assembly over the end of the
long die retaining screw, and position the locator
assembly against the side of the tool jaw.
10. Place the nut onto the end of the long screw
and tighten the nut enough to hold the locator
assembly in place, while still allowing the locator to
slide up and down.
11. To disassemble, close the tool handles until the
ratchet releases, remove the nut, locator assembly,
the two die retaining screws, and the four die
retaining pins, and slide the anvils and crimpers out
of the tool jaws.
