The Quality Connection
Preface:
1)
The YRS series hand tools are designed to crimp smaller sized open barrel
terminals that are side fed and attached to a carrier strip.
2)
The tool was designed for small production lots, samples, and repairs.
3)
Each tool includes a specification sheet which includes the tool part number,
the contact to be crimped, the specific wire to be used, the required tensile
strength, and the strip length for the wire.
4)
The upper die has two crimp positions for different wire sizes. The die must be
set for the wire to be crimped.
5)
The conductor and insulation barrel crimp heights are not adjustable.
Therefore, the wire noted on the tool specification must be used.
Precautions:
1)
Make sure the correct combination of wire, terminal, and tool are used.
2)
The tool does not have a release for the ratchet. Once a cycle is started it must
be completed. If the terminal is not positioned properly or there is a foreign
body stuck in the crimp do not force the handles closed. Doing so will likely
break parts on the tool. Instead remove the adjustment pin and the upper die.
After removing the die the process can be complete releasing the ratchet.
3)
Check the following items prior to use:
a)
Make sure the crimping dies are free from damage, rust, and debris.
b)
Make sure the ratchet releases smoothly after the crimp is complete.
c)
Visual inspection of crimped contact and tensile strength are good.
4)
Do not use the tool for purposes other than crimping.
5)
Periodically add oil to the moving parts and pins on the tool. If the tool will not
be used for long period coat it in oil and store is a rust preventative bag.
6)
Consult JST if the tool beaks or needs to be repaired.
