Please read these carefully also a5 they will help you to avoid most of the “sewing troubles’ you are likely to encount Happy Sewing, DO'S & DON'TS Most Sewing & Sewing Machine problems’ occur by not always carrying out the correct procedures ist of items that, if followed, should help to avoid the most common faults Instruction Book. Below you will find a 1, Read your Instruction Book carefully before you commence sewing, particularly if it involves a new operation. Practice on a piece of waste material before sewing the actual garment. 2, ALWAYS turn the Balance Wheel anti-clockwise TOWARDS YOU. Never commence sewing without fabric under the Presser Foot. 3, ALWAYS ensure that your Needle is in the fabric before applying pressure to the Foot Control, this can be achieved by means of the Balance Wh 4. NEVER pull the fabric away from you while sewing, Allow it to move at the Machine's normal sewing speed. 5. NEVER change position of any of the Machine's Controls with the Needle in the fabric while the Machine is stationary. Otherwise you may break the Needle. 6. On completion of sewing, ALWAYS turn the Needle to its highest point before removing the fabric, which should ALWAYS be drawn away from you towards the back of the Machine. down in the 7. NEVER allow the Machine to continue sewing beyond the end of your fabric as the build up of thread may become entangled in the Raceway underneath the Machine and cause it to jam (see Page 35). 8. Keep your Machine oiled regularly (see Page 34. but NEVER overcoil. Use a good quality Machine Oil, 9 Ensure that the area around the Feed-Teeth is kept clean and free from lint, dust and cotton threads {see Page 34) 10. In the event of the Machine becomming jammed, it will almost certainly be due to incorrect use by allowing excess thread to become entangled in the Raceway (see 7 above). Any obstruction can, how: ever, be easily cleared by following the instructions on page 35. Familiarise yourself with this procedure as I is quite easy and requires no tools. 11, Engure your Tensions are correctly balanced (see Page 14). Try a little sewing on some waste fabric first before sewing the actual garment.

In the centre is 4a smaller Wheel called the Inner Clutch Whee! (1). This is fitted to enable ‘you to disconnect the stitching mechanism of your machine when winding a bobbin, or at any other time when you wish to stop the needle operating, To do this, hold the Balance Wheel still with your left hand and turn the Inner Clutch whee! (1) towards you (as indicated by the arrow) (Fig. 4). To gage for normal sewing turn the Inner Clutch Wheel in the opposite direction. When winding Bobbins, it is always advisable to remove thread from Needle eye before disconnecting Inner Clutch Wheel, Note: When sewing, winding bobbins or changing needles, ALWAYS turn Fia.4 the Balance Wheel towards you i.e, ANTI TO FIT OR CHANGE NEEDLE Lift Presser Foot Lever, and raise Needle Bar (B) to its highest point, by turning Balance Wheel towards you, Loosen Needle Clamp Screw (A) and remove old Needle, Place new Needle Lup into groove of Needle Holder (C) as far it will go, FLAT SIDE AWAY FROM YOU. ‘The re-tighten Needle Clamp Screw (A) firmly with Screwdriver (Fig. 5 ENSURE NEEDLE IS FULLY INSERTED WITH THE HEAD FIRMLY AGAINST THE TOP OF THE NEEDLE HOLDER HOLE.

LOCKWISE (Jo necdte bar VY @= needle Fig. 5 WINDING A BOBBIN REMOVE THREAD FROM EYE OF NEEDLE IN MACHINE. Holding Balance Wheel (2) still with your left hand, loosen the Inner Clutch Wheel (1) by turning towards, you (Fig 4 Page 7). Place spool of thread on Spool Pin (3) and pass thread ‘around the Bobbin Winder Guide (4). Wind some of the thread onto a spare Bobbin (6) and place this onto the Spindle (6) protruding at the end of the Top Plate, ensuring ‘that the small slot on the Bobbin fits onto the small spring at the top of the Spindle, Now push the Lever (7) over and into the Bobbin. ‘Turn the Balance Wheel towards you by hand a few times to wind a little thread onto the Bobbin, You can now operate the Machine but do so rather slowly to maintain even winding. It will shut off automatically when the Bobbin is about 90% full ‘Take off the wound Bobbin and cut off thread RE-TIGHTEN INNER CLUTCH WHEEL READY FOR SEWING a) Fia.6 ADJUSTING BOBBIN WINDER In order that the Thread wound onto the Bobbin runs smoothly whilst sewing, itis most important that it is wound evenly. If correctly carried out it should look like the Bobbin illustrated in Fig, 8 If your Bobbin winds as Figs. 9 or 10 it can be corrected by a simple adjustment to the Rear Thread Guide illustrated as F in Fig, 11 In the case of Fig. 9 release the Screw E, Fig. 11 and slightly LOWER the Guide. In the case of Fig. 10 proceed in the same manner but this time slightly RAISE the Guide. Remember to re-tighten the Serow E, Fig. 11, before resuming sewing, REMOVING & INSERTING BOBBIN CASE To remove Bobbin Case from Machine, raise Needle to its hhighest point by turning Balance Whee! towards you by hand, Ensuring that the Flat-Bed Extension Plate has been removed, open the Raceway Front Cover by simply pulling downwards towards you. Hold the Bobbin Case by the Latch (A) and slide off the Shuttle Centre Spindle (B) as shown (Fig. 12) To replace the Bobbin Case, hold by the Latch (A) and insert onto the Centre Spindle (B), ensuring that the ‘Finger’ (C) engages snugly into the Notch (D). Then release ‘your hold on the Latch. Whenever the Bobbin Case has a Bobbin inside, holding the latch will lock the Bobbin in position inside and prevent it {rom falling out. When the Latch is released, the Bobbin can be easily removed, 10 THREADING AND INSERTING THE BOBBIN INTO THE BOBBIN CASE Holding the Bobbin Case in your Left Hand place the wound Bobbin into it and over the Centre Spindle with your Right Hand with the Thread going in the direction shown (A). With the Right Hand guide the Thread into the Slot (B) in the edge of the Bobbin Case. Gently pull the Thread under the Tension Spring (C) and into the delivery eye (D), leaving a few inches of Thread hanging to be taken up by the Needle later. “The threaded Bobbin Case can now be replaced into the Machine (see Page 10), Always hold @ threaded Bobbin Case by the open Latch as by doing so a ‘catch inside the Bobbin Case will hold the Bobbin and prevent it from falling out (E) Fig 13 " UPPER THREADING (THREADING THE NEEDLE) ‘Start with both the Thread Take-up Lever and the Needle set at their highest points, Also raise the Presser Foot, Place a Reel of Thread onto one of the rear mounted Spool Pins — choose a good quality Thread as poor thread will usually result in poor sewing. Ensure that the Thread being used matches in quality and type with that on your Bobbit 1, Pass the Thread through an Guides (A). 2. Now bring the Thread down towards the Tension Unit (B) and in @ Circular motion pass the Thread around the Tension Unit from RIGHT to LEFT ensuring that it passes smoothly between the two Tension Discs. 3. Continue taking the Thread round to the RIGHT but ensuring that it passes UNDER the flat metal Thread Guard (C) on top of the Tension, 4, Now take the Thread back to the LEFT, over the Thread Guard (C) ‘and then downwards and UNDER the fine wire Check Spring (D). ‘5. From here take the Thread UPWARDS, passing it through the ‘curly’ Thread Guide (D') and continue towards the Thread Take-Up Lever (E), passing it behind the cut-away special slot in a Right to Left direction. 6. Next bring the Thread down and pass behind the Lower Thread Guide (F) — you can see this better by opening the Lamp Cover ~ and then through the Wire Guide alongside the Needle Clamp (G). 7. It now remains only to thread the Needle which must always be carried out from FRONT to BACK (H) FOR TWIN-NEEDLE THREADING SEE PAGE 23, /o of both the Rear and Front Thread 12 PULLING UP THE LOWER THREAD Raise the Presser Foot and hold the Upper Thread lightly (Fig. 15). With the threaded Needle at its highest point turn the Balance Wheel towards you until the Needle has completed one downward and one upward move- ‘ment. By now pulling gently at the Upper Thread, the Lower Thread will appear in the form of a loop (Fig. 16). Should loop not appear first time, move Balance Wheel backwards, then forwards slowly just an inch or so, until loop appears. PREPARING TO SEW Pull the loop gently until it becomes one thread, and then pull gently both Upper and Lower Threads a few inches, passing them under the Prosser Foot (Fig. 16). You are now ready to sew. Place the fabric under the Presser Foot, lower the Presser Foot, turn the Balance Wheel towards you until the Needle enters the fabric and com: mence sewing, FINISHING A SEAM If you wish to secure the stitches at the completion of a seam, simply reverse sew approximately 1/2" (see Fig. 27 Page 18). You should then raise the Needle to its highest point, raise the Presser Foot, move the fabric away from you, and cut both threads. A thread cutter is slotted into the Presser Foot Bar. NEVER RUN THE MACHINE WITHOUT MATERIAL UNDER THE PRESSER FOOT. Fin. 16 13 STITCH FORMATION & TENSION ADJUSTMENT To form a perfect Stitch the Upper and Lower Threads must interlock between ‘the plies of fabric being sewn as in A Fig, 17 When the Upper Tension is too tight and/or the Lower Tension is too loose, the Upper Thread will be seen lying on the surface of the fabric as in & Fig. 17. When the Upper Tension is too loose and/or the Lower Tension is too tight, the lower thread will be seen lying flat on the underside of the fabric as in C Fig, 17. The Tension can be adjusted as follows: UPPER TENSION FIG. 18 MAKE ALL ADJUSTMENTS ON THIS UNIT WITH THE PRESSER FOOT DOWN. Simply turn Tension Knob to the Right to increase Tension and to the Left to decrease Tension. Make only slight movements at a time and ‘check your stitching until the setting suits the material being sewn, Adjusting Seren Increase Tension Tension ‘MADE. Fin, 19 4 LOWER TENSION: (Bobbin Case) Fig. 19. The Tension on this unit is Decrease Usually pre-set before delivery, but should adjustment be necessary, using the small screw driver in the accessory kit turn the small screw on the Tension Spring clockwise to tighten and anti-clockwise to loosen (Fig. 19) ONLY THE MINIMUM ADJUSTMENT OF THiS SCREW MUST BE THE PRESSOMATIC CONTROL The Pressure on the Presser Foot is controlled by the Pressomatic (Figs, 20 and 21. When delivered this control is usually fully depressed and as such, should be suitable for most normal sewing over a wide range of fabrics, However for very fine or very heavy materials some adjustment to the pressure may be necessary. This can be very simply carried out as follows: Push down the outer knurled ring (A Fig. 20) which will allow the centre barrel (8 Fig. 21) to spring upwards and release all pressure. Then depress this centre barrel again as shown (Fig. 21) until the desired pressure is obtained. 10p Feed Dial Z Fia.21 THE DROP FEED CONTROL * ===" When delivered your Machine should have the Feed-Teeth fully RAISED .
