Hariho kandi impanuka mu bimera bya Ashalt, muri rusange bidatera ibibazo, bityo sinasobanuye neza ibisubizo byayo mbere. Ariko muburyo bufatika, nahuye nubundi buryo bwo gutsindwa. Nakagombye nte?

Kunanirwa kwa valve yo gusubirwamo mu ruganda rwa Asfalt ntabwo bigoye, ni ukuvuga imirongo idahwitse, imiyoboro ya electromagnetic, ibitera byananiranye, nibindi bihuye nibitekerezo birumvikana bitandukanye. Kubintu byahindutse bidatinze valve isubira inyuma, muri rusange biterwa n'amavuta mabi, yatsimbaraye ku masoko, ibibi cyangwa umwanda cyangwa umwanda cyangwa umwanda wa peteroli y'ibikoresho byo gusiga. Nibiba ngombwa, amavuta yo gusiga cyangwa ibindi bice birashobora gusimburwa.
Nyuma yo gukoresha igihe kirekire, valve isubira inyuma yambara imyenda ya valve yibanze, ibyangiritse kuri valve stem nintebe ya valve, bikavamo imirongo ya gaze muri valve. Muri iki gihe, impeta ya kashe, valve stem hamwe nintebe ya valve igomba gusimburwa, cyangwa valve isubira inyuma igomba gusimburwa muburyo butaziguye. Kugirango ugabanye igipimo cyo gutsindwa cya asfalt, kubungabunga bigomba gushimangirwa mubihe bisanzwe.
