Niba urushinge rwa valve na valve yumubiri winjiza lisansi bidafunze neza, bifatanyirijwe hamwe cyangwa ibitonyanga byamavuta bibaye, inshinge ya lisansi igomba kubanza gukurwaho hanyuma umubiri wa inshinge numubiri wa valve bigomba gusukurwa namavuta meza ya mazutu. Niba kashe ya kashe iri hagati yinshinge numubiri wa valve Iyo hari ibyobo bito nibyobo, bigomba kuba hasi kubikoresho bidasanzwe cyangwa pliers (menya ko paste yo gusya itagomba kwinjira hejuru yinyerera hagati ya inshinge numubiri wa valve) , hanyuma ugasya hamwe namavuta kugeza urushinge rwumubiri hamwe numubiri wa valve Iyo ibyobo nibyobo hejuru yikimenyetso cya cone byashize bikabura bigahinduka umukara numucyo, kubitera inshinge zometse hagati ya inshinge numubiri wa valve, banza ufate gusohora valve y'urushinge hamwe na pisitori, hanyuma ukayishyira mumavuta ya mazutu asukuye kugirango usukure Isuku, hanyuma ukoreshe ibuye ryamavuta meza cyangwa umusenyi kugirango ugabanye neza (menya ko ibindi bice bitagomba kwambara), kugirango urushinge rushobora kunyerera mu mubiri wa valve, hanyuma ugakoresha gusya hamwe namavuta ya moteri kugirango ushire hejuru ya cone. Gusya kubisabwa haruguru. Niba hari ibyobo byinshi hamwe nibyobo hejuru yubuso bwa kashe hagati yikibiriti cyurushinge numubiri wa valve kandi ntibishobora gusanwa, simbuza inshinge nundi mushya hanyuma uhindure igitutu cyo gutera lisansi hamwe nubwiza bwa atomisiyonike ku ntebe yikizamini cyangwa ibinyabiziga kugirango ukore sure Kugira ngo wuzuze ibisabwa byo gukoresha
