Zomangira zomwe sizingatsegulidwe zimatha kukhumudwitsa ngakhale womanga kapena mainjiniya wodziwa bwino ntchito, koma musanaponye khoma mothedwa nzeru, yesani ena mwa malangizowa kuti mumasule bawuti wamakaniwo. Tenganipo pang'onopang'ono ndipo yesani kumvetsetsa kuti vuto ndi chiyani. Kodi chomangira chachita dzimbiri? Zigawo sizikufanana? Kapena chomangiracho chinali chothina kwambiri? Ngati zosowekazo sizikufanana, yesani kuzisuntha mozungulira kuti muwongole. Moyenera, iwo ayenera kukhala mu malo ofanana ndi mzake monga pamene bawuti anaikidwa. Nthawi zambiri ngodya ya zosowekazo inkasinthidwa, kutseka bawuti pamalo ake. Yesani kugwiritsa ntchito wrench yamphamvu. Ma wrenches a ratchet nthawi zambiri amakhala ofooka kuposa omwe sali a ratchet, ndipo ma wrenches okhala ndi nsagwada zazikulu amakhalanso amphamvu. Wrench ya 6-point kapena ma wrench otseguka ndi abwino kwambiri chifukwa amatha kugwira bwino zomangira kuposa mbiri ya 12-point. Gwedezani wrench mmbuyo ndi mtsogolo, kuyesera kuitembenuza molunjika kenako mopingasa. Izi zikhoza kumasula zigawozo, ndipo izi zidzakhala zokwanira kutsegula clasp. Ngati chokokeracho chachita dzimbiri pang'ono, mutha kupeza kuti dontho la mafuta olowera lomwe latsala kuti lilowerere limamasula dzimbiri ndikukulolani kumasula cholumikiziracho. Ngati sichikugwedezekabe, yesani kugwiritsa ntchito bar yosweka. Zophwanyika ndi ndodo zazitali, zokhala ndi zitsulo zomwe zimapereka mphamvu yowonjezera komanso yofulumira kuposa wrench. Ngati, mukatembenuza khwangwala, cholumikiziracho chimayamba kumva ngati chaphokoso komanso "chofewa", ndiye kuti chingwecho chikhoza kusweka. Kugwedeza wrench (monga pamwambapa) ndiyo njira yabwino kwambiri yopewera chomangira kuti chisweke. Mukhozanso kuyesa kugwiritsa ntchito chingwe chowonjezera. Izi ndi ndodo zapadera zomwe zimakwanira kumapeto kwa wrench, kutalikitsa ndodo kotero kuti mphamvu zambiri zimagwiritsidwa ntchito pa chomangira. Sitikulimbikitsidwa kugwiritsa ntchito ma wrench awiri kuti agwirizane wina ndi mzake chifukwa ndizosavuta kuswa. Ngati dzimbiri ndi zochuluka, gwiritsani ntchito burashi yawaya kuchotsa madera oipitsitsa a dzimbiri kuzungulira chomangira. Samalani kuti musawononge pamwamba pa workpiece. Vinyo wosasa kapena mandimu ndi mchere wosiyidwa kwa maola angapo kapena usiku wonse ukhoza kuwononga zinthu zadzimbiri, zomwe zimapangitsa kuti zikhale zosavuta kuchotsa. Pamene choyipitsitsa chapita, gwiritsani ntchito mafuta olowera monga pamwambapa. Kugwiritsa ntchito blowtorch kutenthetsa chomangira ndikuziziritsa kumatha kuwononga dzimbiri kuzungulira zigawo zake chifukwa chitsulocho chimakula ndikumangika. Njirayi imachepetsa kuuma kwa ma bolts ndipo mwachiwonekere sichivomerezeka kuti igwiritsidwe ntchito pafupi ndi zipangizo zoyaka moto. Ngati cholumikizira sichinasunthe, pangani mafuta anu olowera. Kusakaniza kwa theka la automatic transmission fluid ndi theka la acetone kumapanga chisakanizo cholowera kwambiri chomwe mutha kusiya kwa maola angapo musanayesenso ndi wrench kapena breaker. Mukamagwiritsa ntchito njirazi, kumbukirani kuti ndizosavuta kusintha cholumikizira kuposa zomwe zikusowekapo, chifukwa chake ngati mukufuna kuwononga cholumikizira, chitani!
