Impamvu zituma urunigi rubona rudashobora gutangira ni:

1. Uburyo butari bwo bwo gukora bwatumye urunigi rwuzura silinderi.Mu magambo make, ntabwo ari amakosa, kandi hariho ibintu byinshi nkibi;

2. Niba igipimo cya lisansi ari cyo;

3. Icyuma gishobora kuba kidafite amashanyarazi;

4. Haba hari igishushanyo kuri piston.

Reba uruziga rw'amavuta n'umuzunguruko kugirango urebe niba akayunguruzo k'amavuta kahagaritswe, niba karburetor ivoma bisanzwe, kandi niba icyuma gishyiramo ingufu.Kuraho hejuru yumucyo wacometse, ubishyire kumyuma, hanyuma ukure imashini kugirango urebe niba icyuma gishyiramo ingufu.Kuraho akayunguruzo ko mu kirere hanyuma urebe niba ifite isuku.Kuraho carburetor, fata amavuta muri silinderi, hanyuma ukoreshe imashini inshuro nyinshi.

Niba atari byo, ugomba gusukura karburetor cyangwa kuyisimbuza, hanyuma ukareba silinderi kumpera.Niba udakoresha imashini igihe kirekire mugihe kizaza, ugomba kuvoma amavuta muri tank.Koresha imashini hanyuma utwike amavuta muri carburetor na silinderi.Niba amavuta asigaye abuza carburetor, mubisanzwe usukure akayunguruzo kandi ukoreshe amavuta meza.Byongeye kandi, kashe ya peteroli yangiritse, magnetiki flawheel na crankshaft, crankcase na balancer nibisanzwe.Iyo ibibazo byavuzwe haruguru atariyo mpamvu, birashobora gusuzumwa.
