Do not discard any packing materials without prior scrutiny as to contents. Clean from machine all greases, dirt or dust. Pay particular attention to area around the looper mechanism and looper. 2. Setting-up Machine Assemble knee lifter lever to machine and place on sewing table so that lever is 13m/m distant from front edge of the table. Line up belt groove in belt pulley of handwheel with belt groove of drive mechanism (motor or clutch). Mark three screw hokes for fastening machine to sewing table and place felt pad under machine bed before machine is tightened down. 8. Handwheel Rotation and Speed Turn handwheel only in direction away from operator for clockwise rotation. Be sure motor drive is wired up to obtain the same clockwise rotation. The recommended operating speed of a brand new machine is 1,800 to 2,000 stitches per minute. After a breaking-in period of several weeks and after the operator has become skilled in the operation of the machine, the speed can be increased up to 2,500 stitches per minute. 4 Oilling and Maintenance It is important not to operate the machine before oil of good quality has been filled in each and every oil hole along the top of the machine. When breaking-in a new machine oiling should be done sparingly several times a day. Thereafter, one oiling daily will be sufficient. After oiling, wipe machine carefully to avoid soiling of the material. 1 - 1 Do not operate without material under the presser foot unless the knee lever is depressed. This will prevent damage to the needle and the feed dog as well as the feed plattens. 5. Replacing Needle Turn handwheel away from operator (clockwise) until needle reaches the end of its return stroke (extreme left hand position). Adjust penetration dial to least amount of penetration (turn clockwise towards 1). Remove old or defective needle by loosening needle clamp screw. Insert new needle into seat in needle clamp as far as it will go. Tighten needle clamp screw. Turn handwheel slowly away from operator and observe movement of needle. The curved portion of the needle should bear slightly on the needle guide groove in the left hand part of the presser foot. 1 - 2 Always replace bent or blunt needles. They affect the satisfactory operation of the machine, (see Fig. 1) See par. 10 concerning needle sysetm to be used in Blindstitch Machines. 6. Threading Machine Turn handwheel of machine in clockwise direction away from operator until needle carrier reaches its furthest left hand position. And proceed as follows: Draw thread from spool on thread stand and pass it through thread guide (A) which is located on rear side of thread nipper. Place thread between tension discs of thread nipper and thread tension and lead it forward through thread guide (B) and pass it through thread guide (C) at the top of the arm near its front. From there pass thread through hole in needle clamp and then through the eye of needle from below upward. Pull about 5 cm of thread through the eye of needle, (see Fig 2) 1 - 3 7. Inserting the Work and Starting to Sew Depress knee lifter. This causes the feed plate to swing downward and creates a gap between the presserfoot and the feed plate. Insert the work in the gap just opened in such a manner that the folded or sewn edge of the material is alongside the edge guide of the presser foot, (see Fig. 1) When the material is in proper position, completely release the knee lifter. Get the machine started slowly and watch the material pass edge guide rather than to observe the action of the needle. 8. Adjustment of Needle Penetration The type of material to be blindstitched governs the degree of needle penetration which is required. It is, therefore, recommended to stitch a few centimeters as a test and make adjustments for penetration depending on the appearance of the trial stitching. Turn regulator clockwise for less penetration and counter-clockwise for more penetration. (Fig. 3) Fig. 3 1 - 4 9. Stitch Length Regulation Stitch length adjustment can be easily effected by adjusting needle driving eccentric in arm. Go about it as follows: Turn handwheel by hand pushing plunger until same is felt to drop into a recess within the mechanism inside the arm of the machine. With the plunger remaining depressed into this recess continue turning the handwheel either forward or in reverse until the desired number of stitches per inch is visible on indivator. (see Fig. 4) 10. Needle Recommendation The recommended needle is system LW x 6T. Size Material 3 (11) Cottons. Silks. Acetates, Orion, Dacron and similar type of light weight fabrics. 31/2 (14) Medium weight materials. Woolens and Others. 4 (16) Thick materials for coats, house furnishings. 1 - 5 11. Skip Stitch Device The position of grip at the right side of the machine controls the skip stitch device, (see Fig. 5) When this grip points towards NO SKIP, the needle catches the material at each stitch. Pointing towards SKIP, th...
