THREADING Fig. 6 When a machine is received, note that it has been.threaded correctly. The simplest way to rethread it is to tie the new threads to those already in the machine and pull the new threads through, making sure that the knots will go through the looper eyes. In case the machine requires a complete rethreading, refer to Threading Diagram. REGULATING THREAD TENSION Fig. 6 The amount of tension varies with type of material, size and type of thread, etc. Adjust individual thread tensions as follows. To increase tension Turn nut clockwise To decrease tension Turn nut counter clockwise. Tension on thread should be just enough to secure proper stitch formation. Normally, you should have more tension on the needle threads and less tension on the looper threads.

REGULATING STITCH LENGTH Fig. 14,15 Stitch length is determined by the combination of main and differential feed eccentrics to be used. Outer eccentric actuates differential feed. Inner eccentric O actuates main feed. The number stamped on feed eccentric indicates the number of stitches per inch. However, the stitches made may vary more or less depending upon the material. Selecting eccentric When the stamped number of differential feed eccentric (e.g. #8) is smaller than that of main feed eccentric (e.g. #12), material will tend to shrink in stitching. When the stamped number of differential feed eccentric (e.g. #14) is larger than that of main feed eccentric (e.g. #10), material will tend to stretch in stitching. Changing eccentric Fig. 14,15 1. Remove Nut O and Washer @ from Crankshaft. 2. Screw extractor, furnished with the machine, into screwholeof Differential Feed Eccentric (Spacer for R57L-14S and -19) and take it out. 3.

CHAINING THREAD It is necessary to have a chaining thread approximately 10mm long behind the presser foot when starting to sew. This will avoid "skip-stitches". After replacing needles or thread, check that a continuous, smooth neat chaining thread comes out from under the presser foot. DAILY MAINTENANCE Before morning start * Check oil level is correctly maintained in oil sight gauge. * Check needle is correctly set and not damaged. * Check threading is correct. * Check chaining thread of approximately 10mm long remains behind presser foot. HOW TO CLEAN YOUR MACHINE Cleaning the machine is a simple but important operation. It is not necessary to remove any parts. Merely release the foot and swing it out to the left. Swing out the covers and remove all thecollected lint from around the loopers, feed slots, and under the needle plate. Blow out any loose lint or use a lint brush. Replace covers and return foot to the sewing position. After close of work * Remove dust and lint deposited in the machine specially around needle plate and looper. * If any trouble or irregularity is found, report it to the plant mechanic for adjustment or repair. * Keep record showing number of needle and thread breakage a day. * Dust cover, furnished with machine, should be placed on the machine.
