This is a cutting knife of the machine. In the official JUKI parts list it appears for T series machines.\u003c\/p\u003e\n\u003cp\u003eKnives cut the thread, trim the fabric edge on overlock and similar machines, or cut the slit of a buttonhole. They work as a pair: a moving knife against a fixed (counter) knife, an upper knife against a lower knife on an overlock machine, or a buttonhole knife against its cutting block. The cut is clean only when both edges are sharp and meet with light pressure, so knives are regular wear items.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eJUKI part number: \u003cstrong\u003e70000081\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePart name in the JUKI catalog: Flat Cutter Assembly\u003c\/li\u003e\n\u003cli\u003eType: Knives\u003c\/li\u003e\n\u003cli\u003eListed in 1 model group of the official JUKI parts list\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFits these JUKI machines\u003c\/h3\u003e\n\u003cp\u003ePart 70000081 is used on: JUKI T053.\u003c\/p\u003e\n\u003cp\u003eThe list follows the official JUKI WebPartsList.

If its edge is chipped, rounded or burred, replace both. Set the knife pressure and timing as the JUKI Engineer's Manual for your model describes. Knife edges are very sharp, so handle them with care. Switch the machine off and unplug it before you start, and turn the handwheel by hand through a full stitch before the first run.\u003c\/p\u003e\n\u003ch3\u003eChoosing the right part\u003c\/h3\u003e\n\u003cp\u003eKnives are specific to the machine and its trimmer or overlock mechanism, and many are handed (left or right, upper or lower). On buttonhole machines the size in the name, for example 5\/8, is the buttonhole length the knife cuts.\u003c\/p\u003e\n\u003ch3\u003eQuestions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace both knives at once?\u003c\/strong\u003e\u003cbr\u003eOften, yes. The moving (upper) knife usually wears first, but a new knife against a chipped or rounded partner cuts poorly and wears faster. If the partner's edge is still clean and sharp, replacing one knife is fine.\u003c\/p\u003e","brand":"PRIZZI SEWING MACHINE CO.","offers":[{"title":"Default Title","offer_id":50679730176165,"sku":"JUK-70000081","price":263.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/7593\/5397\/files\/knife_v2.png?v=1792234173","url":"https:\/\/prizzisewing.com\/es\/products\/juki-70000081-flat-cutter-assembly","provider":"PRIZZI SEWING MACHINE CO.","version":"1.0","type":"link"}
