1. Kubungabunga neza, gutakaza bike, urusaku ruke, gusohora igice.
2. Ukurikije igishushanyo mbonera cyimiterere idahagaritswe, irekurwa ryimbere ryibicuruzwa mugihe cyo gutwara birabujijwe.
3. Kurwanya ikirere cyiza, nta gucikamo no kugabanuka kurwego mugihe cyakazi.
4. Ntabwo yunvikana n'ubushyuhe n'umukungugu.
5. Ifite ubushobozi bwiza bwo kurwanya uruziga rugufi rutunguranye.
6. Kurinda umuriro, kwirinda umuriro, kutagira uburozi, kuzimya, kutagira umuriro.
7. Munsi yubushyuhe bwinshi numuriro ufunguye, coil-yumye ya transformateur yumye itanga umwotsi hafi.
8. Ntabwo byangiza ibidukikije.Nyuma yubuzima bwa serivisi, irashobora gusenywa byoroshye, kandi ibikoresho bitwara ibintu birashobora gukoreshwa hamwe hamwe nicyuma.
Ubuso bwose buhuriweho nagasanduku bukozwe ukurikije ibisabwa byo kurinda umuriro kandi birashobora kwihanganira umuvuduko wimbere wa 0.8 MPa.
Igifuniko cy'agasanduku gikozwe mu cyuma.Hano hari insinga ebyiri zisohoka kumurongo, kandi hariho gasketi ya reberi hejuru yumuyaga wamaboko.Umugozi unyura mu cyuma cya reberi.Nyuma yo kwizirika ku ntoki, umugozi urashobora guhagarikwa na gaze ya reberi kugirango ushireho kashe.Umuyoboro wa kabili watoranijwe ugomba guhuza cyane na reberi, kandi umugozi ugomba guhagarikwa cyane kandi ugafungwa rwose kugirango ukore neza.
◆ Hano hari ibitsike byimbere hejuru yimbere yimbere, bigasudwa kumutwe wa kase kandi bigomba guhagarara neza.
Ikarita yimodoka irasudwa hanze yagasanduku k'igikonoshwa kugirango itambike.Irashobora kubikwa mu buryo buhagaritse kugirango ibike umwanya mugihe cyo gutwara cyangwa kubika.
-Ibinyampeke, bikoreshwa cyane-bikonje bikonje bya silicon ibyuma byicyuma, ibyuma byinshi bizenguruka, imiterere ya coil yoroheje, B-ibyiciro bya B, ibikoresho byo gucukura ikirere.
Ikoreshwa mu birombe aho usanga gaze ivanze n'umukungugu w'amakara, kandi hari akaga ko guturika.Irakwiriye gucukura amakara, ibirombe bidafite fer na imishinga ya tunnel.
