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.
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.
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.
11. To disassemble, close the tool handles until the
ratchet releases, remove the nut, the locator
assembly, the two die retaining screws, and the
four die retaining pins, and slide the anvils and
crimpers out of the tool jaws.
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.
4. CONTACT SUPPORT ADJUSTMENT (Figure 3)
NOTE
i
The contact support is preset prior to shipment,
but minor adjustment may be necessary.
1. Make a sample crimp and determine if the
contact is straight, bending upward, or bending
downward.
2. If adjustment is required, loosen the screw that
holds the contact support onto the locator
assembly.
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 screw, and position the locator assembly
against the side of the tool jaw.
NOTE
i
The ratchet has detents that create audible clicks
as the tool handles are closed.
3. Place a contact with wire into the proper nest
and close the tool handles until the ratchet reaches
the sixth click, or until the contact support touches
the contact.
