Pachigawo chake ndi chocheperako, chosowa cha matope omwe chimakwanira kukhala pampando wofanana, kulola kusintha kwa zinthu. Malo owiriawiri ndi magazi amakwaniritsidwa kudzera pazinthu ziwiri zopumira komanso zadothi. Kapangidwe kameneka kumathandizira kuti valavu ikhale yolefukiratu ndi kugwetsa zigawo za pa mapaipi (chivundikiro kawiri) ndikumasula kupsinjika kwa zisindikizo pakati pa zisindikizo (zotuluka), kuwonjezera pa chitetezo chowonjezera.

Mfundo yogwira ntchito ya valavu iyi imasokoneza kuwongolera kwenikweni. Chingwe chikasungunuka, chimangachi chimatuluka m'mimba. Kutembenuza dzanja lamanja kumakankhira singanoyo pampando, kuchepetsa malo omwe amayenda ndikuletsa kuyenda kwapakatikati. Mosachedwa, kuzungulira ma handweel courcreacts kumabweza singano, kukulitsa malo owonda ndikulola sing'anga kuti mudutse. Chiwonetsero chawiri ndipo kusintha magazi kumayamba kusewera pakukonzedwa kapena zochitika zadzidzidzi: Kutseka kwa zisindikizo zonse kumapangitsa kuti pabululi ikhaleponso kokha, kupewa kumasulidwa kosayembekezereka .

Malonda a DBB mmodzi mwadothi amapeza ntchito zambiri monga mafuta ndi mpweya, mankhwala osokoneza bongo, omwe amawongolera makina okhazikika komanso okhazikika. Amakhala ofunika kwambiri pantchito zophatikizira kwambiri, poizoni, kapena kuti azithamangitsa, komwe kumata kutaya pang'ono kapena kudzipatula kumatha kuyambitsa zotsatirapo zoyipa. Kaya mu zitsanzo za zitsanzo, mizere yazikulu, kapena njira zowongolera zolaula, mavuvu izi zimaperekanso ntchito yodalirika komanso yodalirika .

Mwa zabwino zawo zazikulu ndi njira yabwino kwambiri yosinthira, kulola kusintha kwa mphindi kuti mukwaniritse njira zina; Malo owirikiza kawiri ndi magazi, omwe amawonjezera chitetezo chogwiritsira ntchito ndikusinthasintha; ndi kapangidwe kake kamodzi, komwe kumatsimikizira kulumikizana ndi kwaulere kwa ma piverlines.
