Instructions For Using SPARTAN SEWING MACHINE 192
Needles and Thread
Use needles 15 x 1, in sizes 11, 14, 16 and 18. You will obtain the best stitching results from your sewing machine if it is fitted with a SINGER needle.
Thread should be selected according to the fabric to be stitched. Needle must be of correct size for thread to pass freely through eye of needle.
To Set the Needle
- Raise needle bar to its highest position.
- Loosen needle clamp thumb screw and insert needle (flat side to the right) up into needle clamp as far as it will go.
- Tighten needle clamp screw.
Diagram Description (Fig. 1): Shows a sewing machine needle with a flat side on the right, inserted into the needle clamp.
To Thread the Needle
- Raise take up lever 5 to highest point.
- Place spool of thread on spool pin.
- Lead thread into thread guide 1,
- Down and from right to left between tension discs 2.
- Into loop of thread take-up spring 3
- Under slack thread regulator 4 (not through eye in thread regulator)
- Up and from right to left through hole in take-up lever 5
- Down through guide 6 on face plate
- Down through lower wire guide 7.
- Thread from left to right through eye of needle 8.
- Draw about two inches of thread through eye of needle with which to begin sewing.
Diagram Description (Fig. 2): Illustrates the path for threading the sewing machine's upper thread, showing numbered components like the take-up lever, tension discs, and needle guides.
To Remove the Bobbin
- Raise needle to its highest point.
- Open slide plate.
- Press bobbin ejector J and lift out bobbin.
Diagram Description (Fig. 3): Shows the process of removing the bobbin from its case, including opening the slide plate and using the bobbin ejector.
To Wind the Bobbin
- Hold hand wheel K with left hand, and with right hand, loosen stop motion screw L.
- Place bobbin 4 on spindle.
- Press bobbin winder 5 down against hand wheel.
- Place spool of thread on spool pin.
- Lead thread through guide 3 on arm of machine.
- Pass thread through lower notch of guide 6 from front to back and through upper notch from back to front.
- Lead thread from right to left through hole in left side of bobbin.
- Hold end of thread and start machine. (End of thread will break off after a few coils have been wound on bobbin.)
Diagram Description (Fig. 4): Depicts the bobbin winding mechanism, showing the spool placement, thread guides, and the hand wheel engagement.
When Bobbin is Full
- Stop machine, lift bobbin winder away from hand wheel and remove bobbin. Tighten stop motion screw L.
If the Bobbin Does not Wind Evenly
- Loosen screw which holds thread guide 6 to bed and move guide to right or left as required. Then tighten screw.
- If pressure of bobbin winder pulley M against hand wheel is insufficient for winding bobbin, loosen screw N, press bobbin winder pulley against hand wheel and tighten screw N.
To Replace the Bobbin and Thread the Bobbin Case
- Hold bobbin so that thread leads off in direction shown. (Diagram Description Fig. 5: Shows bobbin orientation.)
- Place bobbin in case and draw thread into slot 1. (Diagram Description Fig. 6: Illustrates placing the bobbin in the case.)
- Draw thread between case and tension spring until it reaches notch 2.
- Pull about 3 inches of thread across bobbin.
Diagram Description (Fig. 7): Shows thread being pulled through the bobbin case tension spring.
To Prepare for Sewing
- Turn hand wheel over toward you so that needle enters throat plate and brings up the bobbin thread.
- Close slide plate, allowing thread to enter notch in slide plate. (Diagram Description Fig. 8: Shows closing the slide plate.)
Diagram Description (Fig. 9): Demonstrates the final step of drawing the bobbin thread up through the needle plate.
To Regulate Length of Stitch
Numerals on the indicator represent approximate number of stitches per inch.
- Turn thumb nut to left. Set lever at desired stitch setting.
- Turn thumb nut to right until it rests against indicator plate.
To reinforce a seam, raise stitch indicator lever to its highest position. The machine will then stitch in a reverse direction, making it easy to "back tack."
Diagram Description (Fig. 10): Shows the stitch length indicator dial with settings and a lever for back-tacking.
To Regulate Pressure on Presser Foot
- To decrease pressure, turn thumb screw up.
- To increase pressure, turn thumb screw down.
For ordinary sewing, pressure of the presser foot on the material seldom requires changing. Heavy materials require more pressure than light materials. Pressure should be only heavy enough to move the work along evenly.
Diagram Description (Fig. 11): Illustrates the presser foot pressure adjustment screw.
To Regulate Needle Thread Tension
Numerals on indicator V, Fig. 12, denote different degrees of tension. When tension has been correctly set, note number at line U so that this setting may be regained should the tension be altered for special work.
- To increase tension, turn thumb nut W to higher number.
- To decrease tension, turn thumb nut W to lower number.
Diagram Description (Fig. 12): Shows the needle thread tension dial with indicators U, V, and W.
To Regulate Bobbin Thread Tension
Tension on bobbin thread is regulated by screw A, Fig. 13, nearest center of tension spring. Turn screw A to right to increase tension; turn screw to left to decrease tension.
A perfectly formed stitch results when both tensions are balanced so that the needle and bobbin threads are drawn equally into the fabric.
Diagram Description (Fig. 13): Points out the bobbin thread tension adjustment screw (A).
Diagram Description (Fig. 14): Illustrates a perfect stitch.
Diagram Description (Fig. 15): Shows an imperfect stitch due to needle thread tension being too tight or bobbin thread tension being too loose.
Diagram Description (Fig. 16): Shows an imperfect stitch due to bobbin thread tension being too tight or needle thread tension being too loose.
Care and Maintenance of Your SPARTAN 192
When in regular use the machine should be cleaned periodically.
To Remove and Replace Bobbin Case
- Raise needle and presser foot.
- Draw slide plate to left.
- Remove bobbin from case.
- Lift edge of slide plate and draw it to the right until it is disengaged from spring B. (Diagram Description Fig. 17: Shows the slide plate removed.)
- Lift and move latch C to position shown.
- Grasp bobbin case as shown.
- Tilt case to left and raise forked end above bracket G.
- Turn forked end toward you, then lift out bobbin case. (Diagram Description Fig. 18: Details the steps for removing the bobbin case.)
After Cleaning
- Replace bobbin case with its fork straddling bracket G.
- Twist case to the left, then gently press down and back until edge of sewing hook engages groove under rim of bobbin case.
- Return latch C to its original position.
To Oil the Machine
Apply a drop of oil to each of the places indicated in Figs. 19, 20 and 21. Apply a few drops of oil to the felt pad F, Fig. 13.
Diagram Description (Figs. 19, 20, 21): These diagrams show specific points on the sewing machine's internal mechanisms and exterior where oil should be applied.
