Kuri asfalt ivanga ya ecran ya ecran: kora urugendo rumwe nta mutwaro, hanyuma wongere utangire urugendo. Nyuma yo gusimbuza amashanyarazi mashya, amakosa aracyahari. Reba aho uhurira, kurwanya moteri, kurwanya imashanyarazi na voltage, nibindi, kandi ntakibazo cyabonetse; gukuramo umukandara wohereza, tangira ecran ya ecran, ammeter yerekana ibisanzwe, kandi ntakibazo cyo kugenda muminota 30 udakoresheje imitwaro. Ikosa ntabwo riri mubice byamashanyarazi. Nyuma yo kwanga umukandara woherejwe, ecran yinyeganyeza wasangaga yatsinzwe cyane na blok ya eccentric.
Hagarika eccentric block, tangira ecran ya ecran, ammeter yerekana imyaka 15; metero ya magnetiki yashyizwe kuri plaque ya vibrasi ya ecran ya plaque, imirasire ya radiyo igenzurwa no gushiraho ikimenyetso, kandi radiyo ntarengwa ni mm 3,5; intanga ntarengwa ya diameter y'imbere ni 0.32 mm. Simbuza ecran ya ecran yerekana, shyiramo eccentric block, ongera utangire ecran, kandi ammeter yerekana ibisanzwe. Nta rugendo ruzongera.
