Stitch Partner: Industrial Sewing Machine Spare Parts Guides

By Aashu, Stitch Partner (garment machinery and spares since 1989). Quick answer: an overlock (serger) parts book lists loopers, needle plates, feed dogs, knives and presser feet with part numbers for one model. Many Indian overlocks follow the Pegasus EX pattern, so the Pegasus book often confirms parts for copies too. Free books: Pegasus parts book PDF and Kansai Special part books . Which book covers which machine? Machine Book to open Pegasus EX5200 / EX3200 Pegasus part books Jack E4 / C4 overlock Jack part books Kansai multi-needle (DFB1404P, DFB1412P) Kansai part books Parts you will look up most Needle plate: check the thread count (3, 4 or 5 thread) and stitch width. Feed dog set: main and differential feed are separate part numbers. Upper and lower looper: matched to the stitch type, never mix. Knives: upper and lower knife are ordered separately. Tip: the quantity chart at the end of Pegasus and Jack overlock books shows which parts change between 3-thread, 4-thread an...

Short answer: a JACK model number is a prefix letter for the machine type, a number for the generation and often a suffix for features. A and F are lockstitch, E and C are overlock, W is flatlock or interlock and K is a heavier interlock. A higher number usually means a newer generation. Always confirm with the plate on your machine, because parts and error codes do not carry across every series. The main JACK families A2, A3, A4, A5: single-needle lockstitch, newer ones with an auto trimmer. Error codes: A4/K4/A5 guide . F4, F5, F6: direct-drive power-saving lockstitch. Error codes: F4/F5/F6 guide . E3, E4 and C3, C4, C7: overlock machines, C for heavier work. Error codes: C4/E4 guide . W4, W5 and K4, K5: flatlock and interlock machines for knits and stretch fabrics. Why it matters Each control box has its own error code list, and parts that look alike may not fit across series. Read the model from the plate on the arm or head, and check the control box label. Order th...

Short answer: a JACK E4 or E4S overlock shows E1 to E7, EA, Eb, EC or Ed. Switch off, turn the hand wheel to look for a looper jam, reseat the motor, Hall sensor and positioner plugs, check the 220 V supply and restart. A code that returns at once means the part behind it has failed. What each code means E1 : motor stuck. On an overlock the top cause is thread wrapped round a looper. E2 : controller abnormal or software over-current from heavy fabric or low oil. E3 : parameter save fault, or a loose panel-to-box connection. Hold reset for 3 seconds. E4 : motor Hall signal. Inspect the 10-core connector and sensor wiring. E5 : needle position signal. Turn the hand wheel and check the positioner plug; a worn JACK wheel sensor is common. E6 : speed governor (pedal). Check the plug and coder wire. E7 : current detection circuit. Clean lint and dust from the board and check the voltage. EA, Eb, EC, Ed : over-current, over-voltage, under-voltage and brake resistor faults. Cut po...

A boiler steam iron gives steady, high-pressure steam for hours, which is why garment finishing units, alteration counters and busy laundries prefer it to a simple travel iron. This guide explains how a boiler iron works, how to size one for your workload and how to keep it running without scale and leaks. How a boiler steam iron works Water is heated in a separate boiler and steam travels through a hose to the iron. Because the boiler holds a reserve of hot water and steam, output does not drop when you press long runs of garments. The 2000W industrial steam iron with 4L boiler is an example built for continuous use. Boiler type versus gravity feed A gravity-feed iron drips water from an overhead tank and suits lower daily volume; see the 4L gravity feed steam iron with water tank . Choose a boiler when you press all day and need consistent steam on cotton, linen and heavier fabrics. Sizing checklist Consider garments per day, boiler capacity, heat-up time, wattage and your wiring. L...

A sewing machine that will not start, hums without turning, or runs far slower than it should is one of the most common problems in a garment unit. In most cases the fault is in the motor or its control board, not in the machine head. This guide helps you find the real cause before you spend money on the wrong part. Step 1: Check the simple things first Before you open anything, confirm the power supply is steady, the plug and socket are tight and the pedal cable is not crushed. Many "dead motor" calls turn out to be a loose connector or a pedal sensor that has shifted. Turn the handwheel by hand: if it is stiff, the problem is mechanical (thread jammed in the hook, or dry parts) and the motor is innocent. Step 2: Motor hums but does not turn A humming motor that will not move usually means the belt or pulley is jammed, or the control circuit is sending power but no proper drive signal. Remove the belt and try the motor alone. If it still only hums, the control board is the l...
