Ikirangantego cyanyuma cya mixeur murwego rwo kuvanga ibihingwa bya asfalt bifata ubwoko bwa kashe ihuriweho, igizwe nibice byinshi bya kashe nka kashe ya kashe na kashe. Ubwiza bwa kashe bugira ingaruka kumikorere rusange yikimera cyose.

Kubwibyo, ni ngombwa cyane guhitamo kashe nziza. Impamvu yibanze yo gutemba kwa shitingi yimashini ivanga imashini nkuru ni ibyangiritse kashe ireremba. Bitewe no kwangirika kw'impeta ya kashe hamwe na kashe ya peteroli, amavuta adahagije ya sisitemu yo gusiga amavuta atera kwambara ahanyerera hamwe no kuzunguruka; kwambara kwifarashi iterwa no gutemba kwa shitingi hamwe no guterana hamwe no kuvanga urufunguzo nyamukuru bituma ubushyuhe bwanyuma bwa shaft buba hejuru cyane.
Impera ya shitingi yimashini nkuru nigice aho imbaraga ziba zegeranijwe, kandi ubuzima bwa serivisi bwibice bizagabanuka cyane bitewe nigikorwa cyo guhangayika cyane. Niyo mpamvu, birakenewe gusimbuza impeta ya kashe, kashe ya peteroli, kunyerera hamwe no kuzunguruka mu cyuma cyanyuma cyo gufunga igihe; hamwe no kwifata kuruhande rwimashini nyamukuru imashini yameneka ikoresha ibikoresho byumwimerere byo gufunga, kugirango wirinde ubunini butandukanye kandi wambare vuba, nabyo byangiza uruvange. Reba uburyo bwo gusiga amavuta mugihe:
1. Kwambara ku kizunguruka kizunguruka cya pompe yamavuta ya sisitemu yo gusiga
2. Pungeri yumuvuduko wumuvuduko wa pompe yamavuta nyamukuru ya sisitemu yo gusiga ntishobora gukora neza
3. Umuyoboro wa valve wumutekano wogukwirakwiza amavuta agenda atera imbere muri sisitemu yo gusiga arahagaritswe kandi gukwirakwiza amavuta ntibishobora gukorwa
Bitewe no kunanirwa kwa shaft end sisitemu yo gusiga amavuta yatewe nimpamvu zavuzwe haruguru, pompe yamavuta ya sisitemu yo gusiga igomba gusimburwa.
