Please read the following before operating the tool.
1. Introduction
Thank you for choosing our Hand Crimp Tool.
This document is prepared so that the tool is properly used.
Please take the time to read this manual, making sure you understand the operating
procedures described herein before attempting to operate the tool.
2. Dangerous operations
1) Don’t insert a part of your body or other foreign materials in the hand crimp tool
(hereinafter referred to as the “tool”) while you’re operating the handle of a tool, as injury
my result.
2) Beware of a handle when it is opened. Releasing a ratchet may cause the handle to open
abruptly, resulting in injury.
3) Only users who have received adequate training on usage and safety from their manager,
and have appropriate knowledge and skills must use the tool. Use by unfamiliar users may
cause injury.
<Caution>
1) Unauthorized reproduction of this document in part or in whole is prohibited.

misuse of this document.
A–2
<Safety Precautions>
Please read the following before operating the tool.
3. Careful handling
1) Always check the tool number, applicable terminal and wire size, etc. before using the tool
in the crimping process.
2) Check the tool for any damage, and repair prior to use. Defective crimping may result in
fire.
3) Clean the tool regularly if used frequently.
4) Avoid storing the tool in extremes of temperature, or high-humidity environment.
5) Keep the tool in a place out of reach of children in order to prevent accidents.
4. Must not be carried out
1) Use the tool only for the intended purpose. Don’t use it in place of a hammer, pliers, or other
tools. Don’t remodel the tool. Parts damage may result in accident or injury.
2) Don’t use the tool for unspecified terminals. Don’t crimp unspecified wires. Both may cause
parts damage.
3) The ratchet mechanism of the tool is designed based on operation by the grip of the hand.
Note that improper handling such as inserting it into other devices and opening the handle
forcibly may decrease its capabilities and lifespan.

3. Operation Method
1) Hold the tool handle, and squeeze it until the ratchet is released. Then, unclench your hand.
The handle will be opened by the return spring.
2) Insert a “terminal (1)” into the “crimp section (3)” from the “molex logo mark side (2).” Insert
a “terminal (1)” so that the “molex logo mark side (2)” faces the “contact”, and the “terminal
number engraving side (4)” faces the “barrel (5).”
3) Close the handle lightly until the “barrel (5)” of a “terminal (1)” is held by the “insulation
punch (6)” and “anvil (7).” At this time, the tip of a “locator (8)” is placed between the
“conductor barrel (9)” and the “insulation barrel (10)” so that the “terminal (1)” does not
come off.
* Don’t tighten the handle excessively, as doing so may cause deformation of the crimp part
of a terminal and prevent insertion of a wire.

3. Operation Method (continued)
4) Insert the stripped “wire (12)” from the “terminal number engraving side (4)” until the
“insulation end face (12)” contacts the “locator (8).”
5) Squeeze the tool handle firmly until the ratchet is released (clicks), while holding the wire in
the same position as in below figure.
6) When the ratchet clicks and is released, the handle is automatically opened by the return
spring, and the terminal is crimped.
7) Holding and pulling the “wire (11)” toward the handle gently removes the crimped terminal.
“Note” Don’t tighten the handle excessively after the ratchet is released, as doing so may
over-crimp the terminal and cause wire breakage of parts damage.

4. Daily Maintenance
4.1. Machinery Inspection and Adjustment
1) Check to confirm that the handle moves smoothly (as heeded).
2) After using the tool, always apply machine oil or commercial anti-corrosive oil to the crimp
section, the link, the ratchet, and other moving parts prior to storage (as needed).
3) Loosen the fixing nut for ratchet adjustment screw (eccentric shaft) shown in below figure
by attached “exclusive tool”, and rotate the ratchet adjustment screw to change the position
at which the ratchet is released.
Always adjust the position when the crimp section cannot be fully closed due to parts wear
or the like. Be sure to retighten the fixing nut after completion of adjustment.

4.2. Crimp Terminal Inspection
1) Crimp height of conductor wire (Crimp height)
(1) Always check the crimp height of a conductor wire at the beginning and end of daily
operation, and also check it regularly during operation.
(2) Refer to the specification table provided with the tool for crimp height.
(3) When the crimp height of a conductor wire is not in accordance with the specification, the
tool has damaged or reached the end of its lifespan. Please consult our service personnel.
(4) As this tool crimps wires of various sizes using one set teeth, the insulation crimp height is
for reference only.
“Note” We recommend to measure the crimp height of a conductor
wire by using the “crimp height micrometer” (J5830-001) of
Molex.

4.2. Crimp Terminal Inspection (continued)
2) Wire pullout strength
(1) Be sure to check the wire pullout strength regularly.
(2) Create a test sample like one the below figure and place it in a pullout force tester or a pull
gauge. Then apply the standard pullout force of 25 mm/min. to it, and measure the value at
the point where the wire is pulled out or fractured.
(3) Remember that the insulation section should not be crimped.
3) Crack or deform of terminal
Always check to confirm that the crimped terminal is not cracked or deformed.
Do not crimp the insulation section. Pull out by the speed of 25 mm/min.
