Trouble
From the previous page
Presser foot pressure
Differential feed ratio
Thread amount
Case (1)
The presser foot pressure is not high
enough, providing poor ironing effect.
The differential feed ratio has been set for
gathering.
The looper thread amount is not enough,
causing excessively tensed stitches.
Case (2) Check and Corrective measures
Increase the presser foot pressure.
Set it for stretching. When stretching light-weight
materials, be careful not to cause the presser
foot to contact unevenly with the materials.
Bring the thread cam thread guide fully to the
front to increase the amount of looper thread.
