User manual JUKI MO-734DE

[. . . ] Always unplug the machine from the electrical outlet when removing covers, when covers are opened to raise the knife or thread the loopers, when lubricating or when making any other user servicing adjustments mentioned in the instruction manual. Do not operate where aerosol (spray) products are being used or where oxygen is being administered. To disconnect, turn all controls to the off ''O'' position, then remove plug from outlet. Basically, the machine should be disconnected from the electricity supply when not in use. [. . . ] Place the right-hand needle, flat side towards the back, into the hole of the needle inserter and insert the needle as far as possible into the needle clamp. Tighten the setscrew lightly and then insert the left-hand needle in the same way and tighten both setscrews (C). If the needle is too fine, the thread does not fit into the groove and stitches will be skipped. * It is recommended to use JLx2 needle, especially when sewing thick materials, overlapped section, etc, with overlock machine. Sewing and special overlock threads are manufactured in a wide variety of types, weights and combination of fibres. It is worth investing in good quality threads for perfect sewing results. Decorative threads specially made for overlockers (available on cones) are also becoming widely available. We recommend following the basic guidelines when using special threads on your overlocker: - Purchase threads on cones or spools which are produced exclusively for overlocking. The thread must move easily and without resistance through the thread guides and looper eyes. All purpose overlock 70-90 looper threads thread120/2(polyester) Polyester-continuous filaments Woolly nylon Spun Polyester 80-90 Loopers only Loopers only Neatening edges Soft seams in knits, rolled hems. Switch the machine off (Power switch to "0") Disconnect machine from electricity supply. The two feed dogs move independently and the distance each feed dog travels during one complete movement can be adjusted. The differential feed prevents fluting or waving in knitted or stretch fabrics and movements between the layers of fabric. The distance travelled by the front feed dog should be greater than that of the rear feed dog. The front feed dog, therefore, feeds an amount of fabric which the rear feed dog can take up behind the needle without stretching the fabric. The distance travelled by the rear feed dog should be greater than that of the front feed dog. The front feed dog, therefore, holds the fabric back so that the rear feed dog can take it up behind the needle without any puckering. (F) Adjusting the differential feed The differential feed can be adjusted by simply turning the differential feed adjustment dial in the direction desired. The differential feed is infinitely variable and can be adjusted while sewing. Simply turn the dial in the direction desired for fully variable adjustment while sewing. 7 Wave-free seams (G) Wave-free seams (H) Normal feed (I) No puckering (J) Thick wool knits, hand knitted articles, very stretchy fabrics Cotton, silk, synthetic jersey, sweatshirt fabrics and fine knits Woven fabrics Fine nylon jersey, closely woven fabrics, lining fabric satin, poplin Using the differential feed, a single layer of fabric can be gathered before sewing it to the garment. For example, sleeve heads and lower edges, yokes, lace edging or frills. [. . . ] Fit the replacement knife (from accessory bag) in the groove so that the sharp edge is in line with the stitch plate. Using the special bulb holder provided in the accessory bag, press upwards against the bulb, turn to the left and remove the bulb. Insert into the bulb fixation, press upwards and turn to the right until the bulb engages. Caution: If oil gets in eyes, immediately, rinse the oil out with water. [. . . ]
