increase the stroke of the thread
take-up spring, or to the left to
decrease it.
— 5 —
2）To change the tension of the thread take-up spring
Loosen nut“2”and screw“5”.Turn spring shaft“1”counter clockwise to increase the tension
of the spring, or clockwise to decrease it. Fit a screwdriver in the spring shaft and turn it until the
desired tension is provided.
10. Adjusting the stitch length
Turn stitch length dial counter-clockwise
to bring the desired value to the top of the dial so
that the value is aligned with the pin.
Reverse feed stitching
1）The machine performs reverse feed stitching as
long as the lever is held depressed.
2）The moment you release the lever, the machine
resumed the normal stitching mode.
11. Adjusting the pressure of the presser foot
Pressure to fabric can be adjusted by turning the
pressure adjusting screw.
12. Adjusting the presser foot and the walking foot
1）Loosen not 1, and change the position of the cam
rod boss accordingly.
Highest position---The stroke is maximized. “A”
Lowest position--- The stroke is minimized. “B”。
2）Alternate vertical motions of the walking foot and presser foot
The alternate vertical strokes of the walking foot and presser foot
· Loosen screw ② of the top feed crank..
· Bring the thread take-up lever to its highest position, and lower the presser bar lifting lever. Move
top feed crank ③ to left“A”to increase the stroke of the presser foot, or to the right“B”to
increase it.
