4.7. How to use the throat plate for straight stitch

The throat plate is provided with a useful guide for you to determine the sewing position of material.

Standard throat plate

Throat plate for straight stitches

120
	135
60°	7mm	45°
	7mm	7mm
		7mm
120°		135°

● Guide lines

It is possible to sew the material from its edge by sewing the material while aligning its edge with the guide line on the throat plate.

On center needle position basis

5 mm

* Numbers on the guide line show the distance in mm and inches between the center needle position and the guide line.

Numbers, 7, 10 and 20 are millimeter. Numbers, 1/ 4, 5/ 8 and 1 are inches.

● Angle index

The angle index is useful when using it for piecing of patchworks.

If you align the material edge with the angle index which is same of the angle of patchwork (piece) corner , you will know the start and end positions while setting the seam allowance to 7 mm without marking the material.

T-shape screwdriver

●Attaching the needle

Hold the needle with its flat part facing away from you ( ), and insert it fully until it touches the stopper pin . Securely tighten the needle setscrew.

The needle cannot be inserted unless it is correctly positioned.

● Needles to be purchased

When purchasing spare needles, specify HA×1 (130/705H) or HA×1 SP (needle for knits) .

● Checking the needle

Needle size:

The larger the number, the thicker the needle.

	Check the needle for its straightness occasionally.
	Any bent needle would cause skipped stitches, thread breakage or damage
	to materials.
	The flat part of the needle
	Flat object
	Attention: If the needle is not properly installed or a bent
	needle is used, needle breakage can be caused.
	It will cause damage to the machine.

*In general, the same thread is used for both needle and bobbin threads.

*Thin thread and needle will be used for light-weight fabrics and thick thread and needle will be used for heavyweight materials.

*Check that the combination of needle and thread is OK by trial sewing on the material which will be sewn.

*Knit needle is good for stretchy fabrics (such as knits) and synthetic fabrics.

*Use thread No. 30 - 90.

*When it is difficult to go over an overlapped section, guide the fabric by hand.

*When sewing “quilt patterns”, “decorative patterns” or “letters”, better finish will be ensured by using a knit needle.

		regulator moves to right and return to the
		original position.
		Remove the bobbin from the bobbin
		winding shaft and cut the thread by cutter
		.
		* Bobbin winding will automatically stop even
		while winding, when the winding speed is
		reduced due to a load to the bobbin winding
		motor caused by thread tangling.
