Gawo lapakati la A wheel
Kupanga kwa ROP wapamwamba pobowola mawonekedwe ozama komanso ovuta, kubowoleza PDC nthawi zonse kumaboola kuchokera pansi mpaka pansi mwachindunji kapena kuthamanga kamodzi, kupulumutsa nthawi yayitali ndi mtengo.
Kusiyanitsa ndi tricone bit, PDC kubowola pang'ono kumayenda ndi WOB yotsika koma RPM Yapamwamba, chifukwa chake imagwira ntchito ndi mota yotsikira kuti ikwaniritse liwiro lozungulira.
Magwiridwe a PDC kubowola pang'ono zimadalira kwambiri pa odulira PDC, timapereka yankho lapadera pazofunikira pamitundu yosiyanasiyana.

Pamene gawo lapakati la Gudumu likuyenda pakhoma la chitsime, kuthamanga kwakanthawi kwa bit kumachepetsedwa kwambiri chifukwa chothandizidwa ndi masipoko.
Kudula kumakhala kosalala, moyo wa odulirawo ndiwotalikirapo, ndipo chimbalangondo chimakhala chokhazikika; odulira pamipando amatha kuwonjezera luso locheka mbali.
Popanda kuwonjezera masamba, liwiro la pobowola mbali pang'ono limatha kuwonjezeka ndikuwonetsetsa kuti liwiro likubowola.
Mkulu-mphamvu aloyi zitsulo ndi okhwima kapangidwe mlandu kuonetsetsa chitetezo ndi kudalirika kwa pobowola pang'ono;
Kutuluka kwachangu komanso kwakuya kwamakina opanga ma hydraulic kumatha kuteteza matope pang'ono.
