Detaching and Attaching the Foot Holder

WARNING:

Turn OFF the power switch before detaching or attaching the foot holder.

To detach:

Raise the presser bar and turn the setscrew counterclockwise to remove the foot holder.

q Setscrew w Foot holder

To attach:

Align the hole in the foot holder with the threaded hole in the presser bar and insert the setscrew through the hole. Tighten the setscrew by turning it clockwise.

e Hole r Threaded hole

Raising and Lowering the Presser Foot

The Presser foot lifter raises and lowers the presser foot. You can raise the presser foot about 6 mm (1/4") higher than the normal up position by exerting more pressure when lifting the presser foot lifter. This allows for easy removal of the presser foot and helps you to place thick fabric under the foot.

q Presser foot lifter w Normal up position e Extra lift

Balancing Thread Tension

The thread tension should be adjusted depending on the sewing materials, layers of fabric and sewing method. To adjust the thread tension, turn the tension dial.

q Tension regulating dial w Setting mark

Balanced tension:

The ideal straight stitch has threads locked between two layers of fabric. For an ideal zigzag stitch, the bobbin thread does not show on the right side of the fabric, and the needle thread shows slightly on the wrong side of the fabric.

e Needle thread r Bobbin thread t Right side of the fabric y Wrong side of the fabric

Needle thread tension is too tight:

–if the bobbin thread appears on the right side of the fabric. Loosen the needle thread tension by moving the dial to a lower number.

Needle thread tension is too loose:

–if the needle thread appears on the wrong side of the fabric. Tighten the needle thread tension by moving the dial to a higher number.

Changing Needles

WARNING:

Always make sure to turn the power switch off and disconnect the machine from power supply before changing the needle.

Raise the needle by turning the handwheel and lower the presser foot. Turn off the power switch.

z Loosen the needle clamp screw by turning it

counterclockwise. Remove the needle from the clamp.

q Needle clamp screw

x Insert a new needle into the needle clamp with the

flat side of the needle to the rear. When inserting the needle into the needle clamp, push it up against the stopper pin and tighten the needle clamp screw firmly.

w Stopper pin e Flat side

To check needle straightness, place the flat side of the needle onto something flat (a needle plate, glass etc.) The gap between the needle and the flat surface should be consistent. Never use a blunt needle.
