Hand Crimp Tool
for 1.78mm (.070") Tab Female Crimp Terminals
▲Insulation
Crimp Note:
Due to the terminal’s insulation grip design and/or
insulation diameter range, this tool uses “overlap” form
geometry in the insulation punch. This produces an
overlap insulation crimp (A620 – compliant). While the
insulation punch profile may appear “lopsided”, this is
a normal condition for this tool. See figure to the right.
(Some tools with multiple crimp pockets may not have
the “overlap” profile on all pockets).

Tool Qualification Notes:
1. Pull Force should be measured with no influence from the insulation crimp.
2. The above specifications are guidelines to an optimum crimp.
Note:
A crimp height chart is provided with this document as Reference Only. Due to
the wide range of wires, strands, insulation diameters, and durometers
available, actual crimp height measurements may very slightly. An occasional,
destructive, pull force test should be performed to check hand tool crimp. Pull
Force value Must exceed the Minimum pull force specifications listed.

10. On some large O.D. wires, it may not be possible to insert the
wire with the tool partially closed. Those wires should be
inserted with the hand tool in the open position. Insert the wire
above the terminal in the punch and against the wire stop then
close the tool. See Figure 6.

Right or Left Hand Operation
This hand tool has an added feature that can be converted from a right handed application to a left handed
application. It is necessary to reverse the tooling if using the left handed application along with the locator. Follow
the steps below:
1. The locator must be removed before reversing the tooling.
2. Remove the M3 BHCS which is holding the upper tooling.
3. Flip the upper tooling to the opposite side and replace the M3 BHCS. Make sure the small markings on the
front and back of the hand tool frame, match up and are on the outside of the hand tool frame. See Figure 8
and 9.
4. Do the same thing with the lower tooling and tighten the M3 screws. Be
sure the small markings line up.
5. Reinstall the locator by following the Instructions in the locator replacement
section.
Maintenance
It is recommended that each operator of the tool be made aware of, and
responsible for, the following maintenance steps:
1. Remove dust, moisture, and other contaminants with a clean brush, or soft,
lint free cloth.
2. Do not use any abrasive materials that could damage the tool.
3. Make certain all pins; pivot points and bearing surfaces are protected with a
Figure 10
thin coat of high quality machine oil. Do not oil excessively. The tool was
engineered for durability but like any other equipment it needs cleaning and lubrication for a maximum service
life of trouble free crimping. Light oil (such as 30 weight automotive oil) used at the oil points, every 5,000
crimps or 3 months, will significantly enhance the tool life.
4. Wipe excess oil from hand tool, particularly from crimping area. Oil transferred from the crimping area onto
certain terminations may affect the electrical characteristics of an
RATCHET RELEASE
application.
LEVER
5. When tool is not in use, keep the handles closed to prevent objects from
becoming lodged in the crimping dies, and store the tool in a clean, dry
area.

force the handles open or closed.
The tool will open easily by
pressing up on the ratchet release lever in the movable handle. See Figure

How to Adjust Tool Preload
(See Figure 12)
This hand tool is factory preset to 25-45 LBS. preload. It may be necessary over the life of the tool to adjust tool
handle preload force. Listed below are the steps required to adjust the crimping force of the hand tool to obtain
proper crimp conditions:
