The tool frame holds a die assembly that consists of a
wire anvil, insulation anvil, wire crimper, and insulation
crimper. When closed, the dies form two crimping
chambers. Die retaining pins and die retaining screws
are used to position and secure the dies in the tool
frame.
Attached to the outside of the frame is a locator
assembly, which contains a locator and contact retainer.
A nut is used on the upper die retaining screw to hold
the locator assembly in place.
3. INSTALLATION AND REMOVAL OF
DIE ASSEMBLY, LOCATOR ASSEMBLY, AND
LOWER TERMINAL SUPPORT (See 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 in the
moving jaws of the tool frame so that the chamfered
sides and marked surfaces face outward when
mounted.
3. Insert the two long die retaining pins through the
holes in the tool frame.
4. Insert the short die retaining screw through the
jaw and 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 in
the stationary jaw of the tool frame so that the
chamfered sides and marked surfaces face outward
when mounted.
6. Insert the two short die retaining pins through the
holes in the tool frame.
7. Insert the long die retaining screw through the
jaw and 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 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 die
retaining screw, and tighten the nut enough to hold
the locator assembly in place while still allowing the
locator to slide up and down.
11. Place the lower terminal support over the end of
the short die retaining screw, and position the lower
terminal support against the side of the tool jaw.
12. Place the nut onto the end of the short die
retaining screw, and tighten.
13. To disassemble, close the tool handles until the
ratchet releases, remove the nuts, the locator
assembly, the lower terminal support, the two die
retaining screws, and the four die retaining pins;
then, slide the anvils and crimpers out of the tool
jaws.
