Rethreader ndi chida chamanja chotsuka ndi kukonza mabowo okhala ndi ulusi; zofanana ndi screwdriver, koma ndi nsonga yosiyana.
Ma protrusions pa zomangira, mabawuti, ndodo ndi mtedza kapena mabowo ofanana amatchedwa ulusi.
Kuyenda kungakhale mkati kapena kunja ndipo kumasiyana ndi jenda. Ulusi wakunja, monga wa pa zomangira ndi ma bolt, ndi wakunja, pomwe ulusi wamkati, monga wa pa mtedza ndi mabowo, ndi wamkati. Ulusi wakunja umafanana ndi ulusi wamkati. Ngakhale kuti ulusi wamwamuna ndi wamkazi amapangidwa pogwiritsa ntchito zida zosiyanasiyana, kapangidwe kake ndi kofanana (ngati mutembenuza ulusi wamkazi mkati mwake, udzakhala wofanana ndi ulusi wamwamuna, ndi mosemphanitsa).
Pakapita nthawi, ulusi ukhoza kuwonongeka ndipo ungafunike kukonzedwa. Ndikofunika kuti mukhale ndi ulusi wowongoka bwino kuti kuphatikizika kwa ulusi wamwamuna ndi wamkazi ukhale wosalala ndipo kugwirizana kumapangidwira molondola komanso modalirika. Ulusiwo ukawonongeka, kugwiritsidwa ntchito kosalekeza kudzawononga kwambiri mpaka ulusiwo udzakhala wosagwiritsidwa ntchito.
Winder imabwezeretsa ulusi wamkati. Amachita zimenezi mwa kuwongola chingwe chimene chilipo kale m’malo mopanga china chatsopano.
Cholinga china cha ulusi wa singano ndikuchotsa ulusi wamkati wotsekeka komanso wakuda. Pamene ulusi wa winder ndi ulusi wamkati umalumikizana, chipangizo chochekanso chimatulutsa zinyalala. Ndikofunikira kuti ulusiwo ukhale waukhondo kuti ulusi wachimuna umatsekeka bwino akaulowetsa.
Ogulitsa malonda amafunikira kusamalidwa ndi kusamalidwa pang'ono, amatha kusungidwa ndi zida zina zonse, ndipo angafunike kupukuta mwachangu nthawi ndi nthawi, koma nthawi zambiri amasiyidwa momwe alili.
