Kuphatikiza pa kukhala ndi zida zina zamakina, magwiridwe antchito osalowa madzi ndi gawo lofunikira kwambiri la mtedza wosalowa madzi. Mtedza wosalowa madzi uyenera kuyesedwa mwamphamvu kuti madzi asalowe m'madzi kuti atsimikizire kuti amatha kuletsa madzi kulowa m'malo olumikizirana, monga kuthamanga kwa madzi ndi nthawi yomiza. Ntchito zosiyanasiyana zimafuna mavoti osiyanasiyana oletsa madzi a mtedza wosalowa madzi. Mwachitsanzo, m'malo olumikizira magetsi akunja, kutsekereza madzi kwa IPX4 (splash resistance) kungakhale kokwanira, pomwe zida zapansi pamadzi zingafunike IPX8 kuti madzi asatseke (kumiza kwanthawi yayitali). Kuphatikiza apo, ndikuwonetsetsa chisindikizo, mtedza wosalowa madzi uyeneranso kukhala wokhazikika pamatenthedwe osiyanasiyana, kuwonetsetsa kuti zida zosindikizira monga ma gaskets a mphira sizitaya mphamvu chifukwa cha kusinthasintha kwa kutentha, potero zimasokoneza madzi.
Pankhani yogwiritsira ntchito, mtedza wamba uli ndi ntchito zosiyanasiyana, zomwe zimaphimba pafupifupi madera onse omwe amafunikira kulumikizidwa ndi makina. Pomanga, mtedza wamba umagwiritsidwa ntchito poteteza zitsulo ndi scaffolding; popanga magalimoto, amalumikiza zinthu monga injini ndi chassis; ndi kupanga zida zamagetsi, amateteza matabwa ozungulira ndi ma casings. Malingana ngati chilengedwe chimakhala chouma komanso zofunikira zoletsa madzi sizili zolimba, mtedza wamba ukhoza kuchita bwino.
Mtedza wosalowa madzi umagwiritsidwa ntchito makamaka ngati kuletsa madzi ndikofunikira kwambiri. Mtedza wopanda madzi umagwiritsidwa ntchito pazida zamagetsi zakunja, monga magetsi a mumsewu ndi mabokosi ogawa, kuti asalowetse madzi amvula ndikuteteza zida zamagetsi zamkati ku kuwonongeka kwa chinyezi. Ndiwofunika kwambiri pakupanga zombo ndi uinjiniya wapamadzi, kulumikiza zombo zapamadzi, ma bulkheads, ndi zida zapansi pamadzi kuti zitsimikizire kulumikizana kodalirika komanso kopanda mpweya m'malo amadzi am'nyanja. Kuphatikiza apo, mtedza wosalowa madzi umagwiritsidwa ntchito m'mabafa, zida zosambira, ndi malo ena omwe nthawi zambiri amakhala ndi madzi kuti awonetsetse kuti amagwira ntchito moyenera komanso amakhala ndi moyo wautali.
Pankhani ya kukhazikitsa ndi kukonza, mtedza wamba ndi wosavuta kukhazikitsa ndipo ukhoza kumangirizidwa ku torque yomwe yatchulidwa pogwiritsa ntchito zida wamba monga ma wrenches. Ngati mtedza umakhala wotayirira kapena wowonongeka panthawi yokonza, ndizosavuta kusintha chifukwa cha mawonekedwe ake onse komanso mawonekedwe ake.
