Draw thread from spool and pass it through guide (1) of the thread stand and then, in order , through guides (2)-(8) (Fig.
10 A B 3. Right needle threading (C) For easy threading, disengage the moveable blade by turning it upwards. Push the upper blade holder screw (A) with the forefinger of your left hand and turn the right end of the holder (B) with your right fingers in the direction of arrow (Fig.
11 2. Raise the presser foot. 3. Set tensions to 0 so that the thread knot can pass through the guides smoothly . Draw out the looper thread until the thread knot comes to about 10 cm (4”) past the presser foot. Reset tensions after you have threaded the loopers.
12 2-3 T est sewing Ensure that the upper blade moves against the lower blade correctly by turning the handwheel slowly towards you. If it is not set correctly , check if there is any fabric or waste thread stuck between the blades. T urn the handwheel towards you while holding all 4 threads and applying slight tension.
13 Beginning and end of sewing 1. Beginning of sewing Place your left hand on the fabric to push it slightly until the edge of the fabric passes the presser foot. 2. End of sewing Make chain stitches at the end of the sewing to prevent the threads from coming undone and to prepare for the next sewing (this is called chaining off).
14 1 2 4 3 Presser foot pr essure adjustment The presser foot pressure is pre-adjusted for fabrics of medium (standard) thickness. Adjustment is necessary only when you work on very thin or ver y thick fabrics. Accordingly , sew thinner fabrics with less pressure and thicker fabrics with more pressure.
15 2. When the upper looper thread is unbalanced and lies under neath the fabric: Tighten the thread tension of the upper looper (Dial 3) or loosen the thread tension of the lower looper (Dial 4).
16 0.7-N N N-2 Differ ential feed adjustment The feed dogs work independently of each other to give per fect results when sewing speciality fabrics. Use differential feed to prevent stretching of knit fabrics and puckering of lightweight fabrics. • “N” indicates the neutral position.
17 Stitch width adjustment Adjust the stitch width from 4.2 mm to 6.2 mm according to the kind of fabric. T ypically , wider stitch widths are used for heavier fabrics. The standard width is 4.5 mm. Open the side cover to adjust the width. • T o increase the stitch width, turn the stitch width adjustment dial to a larger number .
18 Sewing curved seams For inside curves, guide the fabric gently with the trimming line of the fabric under the right front of the presser foot. By applying pressure to the fabric with your left hand, at the same time, apply a little pressure in the opposite direction with your right hand as shown.
19 1. Removing the right needle: Create a wide 3-thread stitch by using only the left needle and the left thread tension (Dial 1). The differential feed is normally set at “N” (see p. 16). 2. Removing the left needle: Create a narrow 3-thread stitch by using only the right needle and the right thread tension (Dial 2).

24 1 2 3-6 Corded overlock Corded overlock can be used to strengthen stitches when joining elastic fabrics such as knits. There are two ways to sew corded overlock. 1. Thread cord through the hole on the front of the foot. Place a slightly wide cord or tape (about 3 mm) under the right needle and start to sew catching cord or tape in stitching.
25 0.5-1 1-1.5 Replacing the lower blade: 1. T urn the moveable blade to the non- operating position (see figure C, p. 10). 2. Loosen the lower blade clamp screw and remove the lower blade.
26 4-3 Oiling Lubrication is not necessary for this machine since the major moving parts are all made of a specially-made oil infused metal. However , periodically one or two drops of oil at the oiling point shown will increase its durability .
