1. Kuvamo umubiri wa valve:
Impamvu: 1. Umubiri wa valve ufite ibisebe cyangwa uduce;2. Umubiri wa valve wacitse mugihe cyo gusana
Umuti: 1. Igipolonye gikekwa ko cyacitse hanyuma ubitere hamwe na 4% ya acide nitric.Niba habonetse ibice, birashobora guhishurwa;2. Gucukura no gusana ibice.
2. Igiti cya valve nu mugozi wacyo wo guhuza byangiritse cyangwa umutwe wuruti wacitse 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 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 utume icyuho cyumuryango utwikiriye kimwe;2. Simbuza gasike;3. Gusenya no gusana hejuru yikimenyetso cyumuryango
Icya kane, valve imbere yimbere:
 
Impamvu: 1. Gufunga ntabwo bikomeye;2. Ubuso bwangiritse bwangiritse;3. Ikinyuranyo kiri hagati yimikorere ya valve nigiti kinini cya valve nini 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 yubuso bwa kashe ya valve hamwe nintebe ya valve;3. Hindura ikinyuranyo hagati yimikorere ya valve nigiti cya valve cyangwa usimbuze disiki ya valve;4. Gusenya valve kugirango ukureho jam;5. Ongera usimbuze cyangwa ugaragaze impeta ya kashe
 
5. Intangiriro ya valve itandukanijwe nigiti cya valve, itera guhinduka kunanirwa:
 
Impamvu: 1. Gusana bidakwiye;2. Kwangirika ku masangano ya valve yibanze na stem stem;3. Imbaraga zo guhinduranya zikabije, zitera kwangirika kwihuza hagati ya valve na stem stem;4. Igikoresho cya valve igenzura gasike irekuye kandi igice cyo guhuza Wambara
 
Umuti: 1. Witondere ubugenzuzi 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 bwuburinganire bwubuso;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. Uruti rwa valve rwahujwe nimbuto Tight, cyangwa kwangirika kumutwe uhuye;5. Glande yo gupakira ibogamye;6. Uruti rw'umuryango rwunamye;7. Ubushyuhe buciriritse 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. Ongera icyuho cya valve gikwiye;4. Simbuza igiti cya valve na wire Umugore;5. Hindura ibipapuro bipakira;6. Kuringaniza inkoni y'umuryango 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
