E - STANDARD MACHINE
2.9. AIR PRESSURE REGULATORS ADJUSTMENT
a) Use regulator to adjust the thread blowing pressure - make the adjustment when a new
thread is not blown correctly into the sewing area. Use the flow-controls to avoid thread
returning.
b) Use regulator
to adjust the threading device air pressure so that the threading hook pulls
the thread through the needle smoothly and does not frazzle it.
c) Use regulator
to adjust the thread clamp air pressure. Keep the eye-guard open for this
adjustment! The thread clamp should hold threads softly so that the threading hook can
pull out the thread while threading.
