thread take up lever
’
s highest position). At this time, loosen the set screw (No.9) of the upper feed
lock crank shaft (No.8) and adjust the center line of the bell crank (No.6) to be parallel with the
presser foot bar (No.7).
5) Insert the sewing material (No.10) under the work holder (No.11)and turn the sewing machine pulley
by hand then, stop the presser foot (No.12) at the lowest position.
6) Loosen the presser foot bar set screw (No.14) and move the presser foot bar (No.7) then, adjust the
presser foot (No.12) position to be become the clearance between the bottom surface of the
presser foot (No.12) and the surface of the sewing material 0 to 0.5mm. At the same time, rotate the
presser foot bar (No.7) for the needle (No.15) to come down to the center of the needle hole of the

presser foot become to press the sewing material, the movement of the presser foot
mechanism generates a slight noise. And also, the presser foot stays longer to hold the
sewing material, so the upper thread tension becomes loose or the sewing pattern forming
gets out of shape because the presser foot catches the surface of the sewing material. For
avoiding these troubles, please lower the presser foot as small as possible.
