5. Crimp Height Adjustment
The applicator has two dials that are used to adjust crimp heights. The top dial is marked with letters
A through H and is used to adjust the crimp height of the conductor barrel. The lower dial is marked
with the number 1 through 8 and is used to adjust the crimp height of the insulation barrel.

Insulation Adjustment
CAUTION
1. To avoid damage to the dies from excessive crimping set the dials to H-8 to begin crimp height
adjustment.
2. The proper dial settings may differ depending on the wire. Always measure the crimp height with a
micrometer to be sure the crimp height meets the desired value.
3. If the applicator does not provide the desired by adjusting the dials, replace the wire block of
insulation block. Various sizes are available from JST. Tell JST the numbers on the blocks you are
using and how far out of spec the crimp height is and we will be able to assist with the appropriate
blocks. Do not adjust the shut height of the AP-K2N press to adjust crimp height.

Conductor Crimp Height Adjustment
5-1-1
Turn the power to the press off and be sure the motor has come to a complete stop.
5-1-2
Set the top dial in the H position. This is the highest crimp height and is always the
correct starting position.
5-1-3
Measure the crimp height and check to see if it is within the specification found on the
Die Construction Sheet. If it is not within the specification lower the letter setting on
the dial. The crimp height will decrease approximately .002” (0.05mm) per graduation.
Continue the process until the correct crimp height is achieved.

Insulation Crimp Height Adjustment
5-2-1
Turn the power to the press off and be sure the motor has come to a complete stop.
5-2-2
Set the bottom dial in the 8 position. This is the highest position and is always the
correct starting position.
5-2-3
Crimp a sample. If the desired crimp height is not attained lower the dial number.
Continue the process until the desired crimp height is attained.
