M'nkhaniyi ndikufuna kukudziwitsani za chida chodziwika bwino cha zida zopanda zingwe zotchedwa "drill driver hammer drill". Mitundu yosiyanasiyana ndi yofanana modabwitsa potengera kuwongolera, mawonekedwe ndi magwiridwe antchito, ndiye zomwe mukuphunzira pano zikugwira ntchito pagulu lonse.

Kolala yakuda pa 18 volt iyikubowola nyundo yopanda chingweikuwonetsa "njira" zitatu zomwe chida ichi chingagwire ntchito: kubowola, kubowola, kubowola nyundo. Chidacho chili pakali pano pobowola. Izi zikutanthauza mphamvu zonse zimapita ku kubowola pang'ono, popanda kutsetsereka kwa clutch yamkati.

Ngati mutembenuza kolala yosinthika kuti chithunzi cha "screw" chigwirizane ndi muvi, mumakhala ndi mawonekedwe akuya osinthika. Munjira iyi kubowola kumapereka kulimba kwina kwa screw yomwe mukuyendetsa, koma osatinso. Galimoto imazungulirabe mukagunda choyambitsa, koma chuck sichitembenuka. Zimangotsetsereka kutulutsa phokoso ngati momwe zimachitira. Njira iyi ndi yoyendetsera zomangira mozama nthawi zonse. Kutsika kwa nambala pa mphete yosinthika yosinthika, torque yocheperako imaperekedwa ku chuck. Akamanena za woyendetsa kubowola, akutanthauza kuthekera kopereka ma torque osiyanasiyana monga chonchi.

Kubowola uku tsopano kuli mu nyundo. Chuck imazungulira ndi mphamvu zonse ndipo palibe kutsetsereka, koma chuck imanjenjemera mmbuyo ndi mtsogolo pafupipafupi. Ndi kugwedezeka kumeneku komwe kumapangitsa kubowola kwa nyundo kubowola mabowo mumiyala osachepera 3x mwachangu kuposa kubowola kopanda nyundo.

Njira yachitatu ndi njira yachitatu yobowola iyi. Mukatembenuza mphete kuti chithunzi cha nyundo chigwirizane ndi muvi, zinthu ziwiri zimachitika. Choyamba, chuck ipeza torque yonse ya injini. Sipadzakhala kutsetsereka kolamuliridwa monga zimachitika mumayendedwe oyendetsa. Kuphatikiza pa kuzungulira, palinso mtundu wina wa nyundo yogwedezeka kwambiri yomwe imakhala yothandiza kwambiri pobowola miyala. Popanda nyundo, kubowola uku kumayenda pang'onopang'ono mu zomangamanga. Pogwiritsa ntchito nyundo, kukumba kumapita patsogolo kwambiri, mwachangu kwambiri. Nditha kuthera maola ambiri ndikuyesera kuboola bowo popanda nyundo, pomwe zingatenge mphindi kuti ntchitoyo ichitike.

Masiku ano,zida zamagetsi zopanda chingweonse ali ndi mabatire a lithiamu ion.Sizidzitulutsa zokha pakapita nthawi, ndipo teknoloji ya lithiamu-ion ikhoza kutetezedwa ku zowonongeka zomwe zimadza chifukwa cha kudzaza kapena kulipiritsa batri yomwe ikutentha kwambiri. Lithium-ion ilinso ndi zinthu zina zomwe zimapanga kusiyana. Ambiri ali ndi batani lomwe mungasindikize kuti muwone momwe batire ilili. Ngati mudakumana ndi zokhumudwitsa ndi zida zopanda zingwe m'mbuyomu, dziko latsopano la zida za lithiamu ion lidzakudabwitsani ndikukusangalatsani. Ndi njira yopitira.
