[Response to problems occurring at the beginning of sewing]
• In the case needle thread breakage occurs when using a thin thread or fragile thread
• In the case needle thread is not tucked on the wrong side of material
• In the case needle thread breakage occurs when starting sewing from the material end (such as sew-
ing the material with needle thread tucked on the undersurface of material)
In the case any of the aforementioned problems occurs, the assist function which reduces the presser
foot pressure at the beginning sewing can be set by using the active presser lifting device.
* In the case the assist function is not used, adjustment should be carried out to allow the needle
thread placed between the presser foot and the material to smoothly come out from between them
by decreasing the presser foot pressure.
Adjust the presser foot pressure and the sewing speed appropriately to prevent insufficient feed ef -
ficiency due to jumping or other faults of the presser foot. Confirm the adjustment result by actually
sewing the material.
[How to set the active-presser assist
function]
1) Enter the presser foot lift setting time
with "U290".
2) Press ❶ to confirm the entered
value.
Factory-set value : 40
1. The amount of uplift of the presser foot above the throat plate varies according to the
material thickness of the item to be sewn and the presser foot pressure. Be sure to
check the actual condition before starting sewing.
2. If the adjustment value of the operating time of the AK-154 is increased while the press -
er foot pressure is high, the operating noise will become larger. Adjust the adjustment
value of the operating time of the AK-154 and the pressure foot pressure while visually
checking the needle thread.
