Needle Depth

The needle depth should be set after any of the following:

• replacement of any of the needle bars or needlecase assembly four-packs

• disassembly of the needlecase assembly

• when diagnostic tests determine resetting of needle depth is necessary

To set the needle depth, the AMAYA OS must be started and the machine must be turned on.  Refer to the following procedures to set the needle depth.

4. Look directly into the hook assembly and check the location of the needle’s eye compared to the figure above. 0 - 1/4 of the through portion (the portion that you can see through) of the needle eye should be visible in the hook assembly.   If the needle’s eye is in the acceptable range, skip the next few steps and go to Step 7.  If the needle’s eye is not in the acceptable range, continue this procedure with the next step.

5. Loosen the set screw on the needle bar drive stud and move the needle bar up or down until needle depth is correct.  (0-1/4th of the needle eye through portion should be visible)  Repeat step 4 above and repeat this step again if the needle depth is not correct.

6. Click the Head Up button and then the Bottom Center button and check that the needle is at the proper needle depth position.  If it is not, go to step 5 above.

7. Click on Head Up.   Color change to the next color.

8. Repeat steps 3 through 7 until needle depth is set on all 16 needles.

9. Reinstall the bobbin and bobbin case.

10. Run the following AMAYA test designs on the machine:

• AMTBTESTXXX.EXP (Thread Break Test)

• AMRTESTXXX.EXP (Looping Test)
