Chechina, iyo valve yemukati inodonha:
 
Zvikonzero: 1. Kuvhara hakuna kusimba; 2. Nzvimbo yekubatana yakakuvadzwa; 3. Mukaha uri pakati pepakati pevharuvhu uye hunde yevharuvhu yakakura zvakanyanya, zvichiita kuti tsinga yevharuvhu inyunguduke kana kubata zvisina kunaka; 4. Iyo yekuisa chisimbiso haina kunaka kana iyo yevhavha core yakajairirwa.
 
Kurapa: 1. Kuvandudza kushanda, kuzarura kana kuvhara; 2. Bvisa vharafu, dzokororazve chisimbiso chevhavha yepakati uye chigaro chevhavha; 3. Gadzirisa mukaha pakati pepakati pevharuvhu uye hunde yevharuvhu kana kutsiva dhisiki yevharuvhu; 4. Disassemble valve kubvisa jamu; 5. Dzorerazve kana kuisa chisimbiso mhete
 
5. Mutsindo wevharuvhu wakapatsanurwa kubva pahunde yevharuvhu, zvichiita kuti switch ikundikane:
 
Zvikonzero: 1. Kugadzirisa kusina kunaka; 2. Kuora panosangana simbi yevharuvhu netsinde revharuvhu; 3. Yakawandisa chinja simba, zvichikonzera kukanganisa kunosangana pakati pevharuvhu core uye valve stem; 4. The valve core check gasket yakasununguka uye chikamu chekubatanidza Wear
 
Kurapa: 1. Ngwarira kuongorora panguva yekugadzirisa; 2. Tsiva mudonzvo wegonhi rezvinhu zvisingaite ngura; 3. Usazarura valve nesimba, kana kuti ramba uchivhura valve mushure mokunge oparesheni isati yazarurwa zvakakwana; 4. Tarisa uye shandura zvikamu zvakakanganisika
 
Nhanhatu, kune makatsemuka mupakati pevhavha uye chigaro chevharuvhu:
 
Zvikonzero: 1. Kushata kwepamusoro kwehutano hwekubatana kwepamusoro; 2. Kusiyana kukuru kwekushisa pakati pemativi maviri evhavha
 
Kurapa: gadzirisa makatsemuka, kupisa kupisa, kupukuta mota, uye kukuya zvinoenderana nemirairo.
 
Zvinomwe, tsinde yevharuvhu haishande zvakanaka kana switch haifambi:
 
Zvikonzero: 1. Inovharwa zvakanyanya mumhepo inotonhora, uye inowedzera kusvika pakufa mushure mekupisa kana kuti yakanyanya kusimba mushure mekunyatsovhurwa; 2. Kurongedza kwakanyanyisa; 3. Ivhavha hunde gap idiki uye inowedzera; 4. Dzinde revharuvhu rakafananidzwa nenati Tight, kana kukuvadzwa kweshinda inofananidzwa; 5. Gland yekurongedza inorerekera; 6. Hunde yegonhi yakakombama; 7. Tembiricha yepakati yakanyanyisa, mafuta haana kunaka, uye hunde yevharuvhu yakasvibiswa zvakanyanya.
 
Kurapa: 1. Mushure mekupisa muviri wevhavha, edza kuzarura zvishoma nezvishoma kana kuzarura zvakakwana uye zvakasimba uye wozovhara zvakare; 2. Muedzo wakavhurika mushure mekusunungura gland rekurongedza; 3. Wedzera gap revhavha yehunde zvakakodzera; 4. Tsiva hunde yevharuvhu newaya Mukadzi; 5. Rongedza mabhaudhi egland ekurongedza; 6. Rongedza tsvimbo yegonhi kana kuitsiva; 7. Shandisa pure graphite powder semafuta emudonzvo wegonhi
 
Eight, kurongedza kuvuza:
 
Zvikonzero: 1. Iyo yekurongedza zvinhu haina kururama; 2. Gland yekurongedza haina kumanikidzwa kana kusarura; 3. Nzira yekuisa kurongedza yakashata; 4. Kumusoro kwechitsiko chevhavha chakakuvadzwa
 
Kurapa: 1. Sarudza kurongedza nemazvo; 2. Tarisa uye gadzirisa ganda rekutakura kuti udzivise kudzvinyirira kutsauka; 3. Isa kurongedza maererano nenzira yakarurama; 4. Gadzirisa kana kutsiva hunde yevharuvhu
