q Power Switchw Foot Control Pluge Machine Socketr Machine Plugt Power Supply Plugy Wall Outlet

For Your Safety:While in operation, always keep your eyes on thesewing area, and do not touch any moving parts suchas the thread take-up lever, handwheel or needle.Always turn off the power switch and unplug from thepower supply:

- when leaving the machine unattended.- when attaching or removing parts.- when cleaning the machine.

Do not place anything on the foot control, otherwisethe machine will run intermittently.

When the power is turned on, the indicator window willshow a test pattern then will indicate 01.

Controlling Sewing Speed

Speed control slider

You can limit the maximum sewing speed with thespeed control slider according to your sewing needs.

To increase sewing speed, slide it to the right.

To decrease sewing speed, slide it to the left.

Foot control

Pressing on the foot control can vary sewing speed.The harder you press the foot control, the faster themachine runs.

NOTES:The machine runs at the maximum speed set by thespeed control slider when the foot control is fullydepressed.Keep the foot control free from accumulation of lint,dust and loose cloth.Do not place anything on the foot control.

Operating Instructions:Foot controller Model 21371 is for use with sewingmachine model DC3050.

Operating Instructions:The symbol "O" of a switch indicates the "off" position of a switch.For appliances with a polarized plug (one blade wider than the other). To reduce the risk of electric shock, thisplug is intended to fit in a polarized outlet only one way. If it does not fit fully in the outlet, reverse the plug. If itstill does not fit, contact a qualified electrician to install the proper outlet. Do not modify the plug in any way.

Balancing Thread Tension

Auto tensionThis machine features an Auto setting in the tensioncontrol, which covers a wide range of sewingconditions. Set the tension regulating dial at "A" forgeneral sewing, unless specifically indicated in thismanual.

q Tension regulating dialw Setting mark

Balanced tension:The ideal straight stitch has threads locked betweentwo layers of fabric.For an ideal zigzag stitch, the bobbin thread does notshow on the right side of the fabric, and the needlethread shows slightly on the wrong side of the fabric.

e Needle threadr Bobbin threadt Right side of the fabricy Wrong side of the fabric

Manual tension adjustmentManual tension adjustment may be neededdepending on the sewing materials, layers of fabricand other sewing conditions.

Needle thread tension is too tight:-if the bobbin thread appears on the right side of thefabric.Loosen the needle thread tension by moving the dialto a lower number.

Needle thread tension is too loose:-if the needle thread appears on the wrong side of thefabric.Tighten the needle thread tension by moving the dialto a higher number.

Raising and Lowering the Presser Foot

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

This stitch is used to finish a raw edge of syntheticsand other stretch fabrics that tend to pucker.Sew along the fabric edge leaving an adequate seamallowance.

After sewing, trim the seam allowance close to thestitches.

Overcasting stitch

This stitch can be used to simultaneously seam andovercast edges of fabrics.Use this stitch when you do not need to open seams flat.Place the fabric edge next to the guide of the foot andthen sew.

Buttonholes

Variety of buttonholes

#06 Square buttonholeThis square buttonhole is widely used on medium toheavy weight fabrics.The buttonhole size is automatically determined byplacing a button in the rear of the foot.

#07 Round-end buttonholeThis buttonhole is used on fine to medium weightfabrics especially for blouses and children’s clothes.

#08 Keyhole buttonholeThe Keyhole Buttonhole is widely used on medium toheavy weight fabrics. It is also suitable for larger andthicker buttons.

Square buttonhole

NOTES:• The size of a buttonhole is automatically set by

placing a button in the rear of automatic buttonholefoot R.

• The button holder of the foot takes a button size of0.5 cm (3/16 ”) to 2.5 cm (1”) in diameter.

• It is sometimes necessary to change the buttonholesize to match certain heavy or specific fabrics andthreads.

• Make a test buttonhole on an extra piece of thefabric to check your settings.

• The preset width of the buttonhole is suitable forordinary buttons.

• Apply an interfacing to stretch or fine fabrics.
