PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use
and low volume applications. A wide selection of powered application equipment for extended-use, production operations is available.

1. INTRODUCTION
Hand Crimping Tool 90066-7 and Head Assembly
90066-9 (shown in Figure 1) are designed to crimp
Type III+ and Type VI, and commercial MATE-N-LOK*
contacts listed in Figure 2. Read these instructions
thoroughly before crimping any contacts.
All dimensions on this document are in metric units
[with U.S. customary units in brackets]. Figures and
illustrations are for reference only and are not
drawn to scale.
Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.
2. DESCRIPTION
(Figures 1 and 2)
The front of the tool (contact side), into which the
contact is inserted, has the tool number marked on it.
The back of the tool (wire side), into which the wire is
inserted, has the wire size and color-code dots
marked above each crimping chamber.
The tool features two fixed dies (crimpers), two
movable dies (anvils), two crimping chambers, a
contact support, a locator/insulation stop, an ejector,
and ratchet.
The ratchet ensures full crimping of the contact. Once
engaged, the ratchet will not release until the handles
have been FULLY closed.
The dies bottom before the ratchet releases.
This is feature ensures maximum electrical and
tensile performance of the crimp. DO NOT re-
adjust the ratchet.
The locator/insulation stop has two functions. First, it
positions the contact between the crimping dies, and
second, it aids in locating the wire in the contact. In
use, it rests in the locator slot. See Figures 2 and 3.
The contact support prevents the contact from
bending during crimping. The ejector pulls the locator
down and ejects the crimped contact when the tool
handles are FULLY opened.
Type III+ contacts have a color dot located on the
contact spring. Type VI contacts have the
applicable wire size stamped on the underside of
the insulation barrel.
3. CRIMPING PROCEDURE
Refer to Figure 2, and select wire of the specified size
and insulation diameter for the type and part number
of loose piece contact. Strip the wire to the length
indicated. DO NOT cut or nick the wire strands.
On the BACK of the tool, identify the appropriate
crimping chamber (according to the color dot and/or
wire size markings). The markings on the contact must
match the markings on the appropriate crimping
chamber of the tool.
Refer to Figure 3, and proceed as follows:
1. Hold the tool so the BACK (wire side) is facing
you.
2. Make sure the ratchet is released by squeezing
the handles and allowing them to open FULLY.
3. Insert the contact (insulation barrel first) into the
FRONT of appropriate crimping chamber. Position
the contact in the crimpers so that the locator enters
the locator slot of the contact.
