2. DESCRIPTION
The FRONT of the tool, into which the contact is
inserted, can be identified by the tool part number on
the link. The tool features a stationary die (6.35 [.250]
wide F crimp nest), rotatable anvil die with three
settings, hold–down device, and contact locator. The
anvil must be set to the wire size being used. The
applicable wire size is stamped on the base of the
anvil die. When closed, the dies form one crimping
chamber.
The hold–down device and contact locator are
mounted on a metal strip. The metal strip must be
adjusted to accommodate the contact position during
the crimping process.
3. CRIMPING PROCEDURE
Refer to Figure 2, and strip the wire to within the
dimensions shown.
DO NOT use wires with missing or nicked
conductor strands.

Proceed as follows:
1. Open the tool head. Make sure that the anvil die
is locked in position and that the locator pin is
visible as shown in Figure 1. It is not necessary at
this time to set the anvil die to a specific wire size.
2. Place a sample contact in the nest of the
stationary die as shown in Figure 3. The open end
of the wire barrel must be aligned in the nest.
3. Loosen the two screws securing the hold–down
device and contact locator, and position the contact
locator over the contact tongue as shown in Figure
3. Do not re–tighten the screws at this time.
The hold-down device and contact locator must
be properly adjusted so that the contact will
remain aligned during the crimping process.
