1. Kumeneka kwumubiri wa valve:
Impamvu: 1. Umubiri wa valve ufite ibisebe cyangwa uduce; 2. Umubiri wa valve wacitse mugihe cyo gusana
Umuti: 1. Polonye ikekwa ko ikomye hanyuma uyishire hamwe na 4% ya acide nitric. Niba habonetse ibice, birashobora guhishurwa; 2. Gucukura no gusana ibice.
2. Igiti cya valve nu mugozi wacyo wumugore wangiritse byangiritse cyangwa umutwe wuruti uravunika cyangwaAGACIRO K'UMUPIRAuruti rwunamye:
Impamvu: 1. Imikorere idakwiye, imbaraga zikabije kuri switch, kunanirwa igikoresho ntarengwa, no kunanirwa kurinda umuriro. ; 2. Urudodo rukwiranye rurekuye cyangwa rufunze cyane; 3. Ibikorwa byinshi cyane nubuzima bwa serivisi ndende
 
Umuti: 1. Kunoza imikorere, imbaraga zitaboneka ni nini cyane; reba igikoresho ntarengwa, reba igikoresho kirinda umuriro; 2. Hitamo ibikoresho bikwiye, kandi kwihanganira inteko byujuje ibisabwa; 3. Simbuza ibice byabigenewe
 
Icya gatatu, bonnet ihuriweho hejuru iratemba
 
Impamvu: 1. Imbaraga zidahagije zo gukomera cyangwa gutandukana; 2. Igipapuro nticyujuje ibisabwa cyangwa igitereko cyangiritse; 3. Ubuso buhuriweho bufite inenge
 
Umuti: 1. Kenyera ibihindu cyangwa ukore icyuho cyumuryango utwikiriye kimwe; 2. Simbuza gasike; 3. Gusenya no gusana hejuru yikimenyetso cyumuryango
Icya kane, valve imbere yimbere:
 
Impamvu: 1. Gufunga ntabwo byoroshye; 2. Ubuso buhuriweho bwangiritse; 3. Ikinyuranyo kiri hagati yimikorere ya valve nigiti kinini ni kinini cyane, bigatuma intandaro ya valve igabanuka cyangwa igahuza nabi; 4. Ibikoresho byo gufunga birakennye cyangwa intoki ya valve irahuzagurika.
 
Umuti: 1. Kunoza imikorere, gufungura cyangwa gufunga; 2. Gusenya valve, ongera usya hejuru yikidodo cyimbere ya valve nintebe ya valve; 3. Guhindura ikinyuranyo hagati yimikorere ya valve nigiti cya valve cyangwa gusimbuza disiki ya valve; 4. Gusenya valve kugirango ukureho jam; 5. Ongera usimbuze cyangwa ugaragaze impeta ya kashe
 
5. Intangiriro ya valve yatandukanijwe nigiti cya valve, bigatuma ihinduka ryananirana:
 
Impamvu: 1. Gusana bidakwiye; 2. Kwangirika ku masangano ya valve yibanze na stem stem; 3. 4. Igikoresho cya valve igenzura gasike irekuye kandi igice cyo guhuza Wambara
 
Umuti: 1. Witondere kugenzura mugihe cyo kubungabunga; 2. Simbuza inkoni yumuryango ibikoresho birwanya ruswa; 3. Ntukingure valve ku gahato, cyangwa ukomeze gukingura valve nyuma yimikorere idafunguye neza; 4. Reba kandi usimbuze ibice byangiritse
 
Gatandatu, hari uduce twibikoresho bya valve hamwe nintebe ya valve:
 
Impamvu: 1. Ubwiza bugaragara bwubuso bwubusabane; 2. Itandukaniro rinini ryubushyuhe hagati yimpande zombi za valve
 
Umuti: gusana ibice, kuvura ubushyuhe, gusiga imodoka, no gusya ukurikije amabwiriza.
 
Birindwi, igiti cya valve ntigikora neza cyangwa switch ntigenda:
 
Impamvu: 1. Ifunze cyane mubihe bikonje, kandi iraguka kugeza apfuye nyuma yo gushyuha cyangwa irakomeye cyane nyuma yo gufungura byuzuye; 2. Gupakira birakomeye; 3. Ikinyuranyo cya valve ni gito cyane kandi kiraguka; 4. Igiti cya valve cyahujwe nimbuto Tight, cyangwa kwangirika kumutwe uhuye; 5. Glande yo gupakira ibogamye; 6. Uruti rw'umuryango rugoramye; 7. Ubushyuhe bwo hagati buri hejuru cyane, amavuta ni mabi, kandi uruti rwa valve rwangirika cyane
 
Umuti: 1. Nyuma yo gushyushya umubiri wa valve, gerageza gukingura buhoro cyangwa gufungura byuzuye kandi bikomeye hanyuma wongere ufunge; 2. Ikizamini gifunguye nyuma yo gupakurura glande; 3. Kongera icyuho cya valve ikwiye; 4. Simbuza igiti cya valve na wire Umugore; 5. Hindura ibipapuro bipakira; 6. Kuringaniza inkoni yumuryango cyangwa kuyisimbuza; 7. Koresha ifu ya grafite isukuye nk'amavuta yo kwisiga
 
Umunani, gupakira ibintu:
 
Impamvu: 1. Ibikoresho byo gupakira ntabwo aribyo; 2. Glande yo gupakira ntabwo ihagarikwa cyangwa ibogamye; 3. Uburyo bwo gushiraho ibipaki ni bibi; 4. Ubuso bwuruti rwa valve bwangiritse
 
Umuti: 1. Hitamo gupakira neza; 2. Kugenzura no guhindura glande yo gupakira kugirango wirinde gutandukana; 3. Shyiramo ipaki ukurikije uburyo bwiza; 4. Gusana cyangwa gusimbuza igiti cya valve
