(4) Ingaruka insinga ya drill igomba kurindwa neza. Birabujijwe rwose kuyikurura hasi kugirango wirinde kumeneka no gutemwa, kandi ntibyemewe gukurura insinga mumazi yamavuta kugirango wirinde amavuta namazi kwangirika.

. Niba bigaragaye ko imyitozo yingaruka ifite kumeneka, kunyeganyega bidasanzwe, ubushyuhe cyangwa urusaku rudasanzwe mugihe cyo kuyikoresha, igomba guhagarika ako kanya igashaka amashanyarazi yo kugenzura no kuyitaho mugihe.
(6) Mugihe usimbuye bito, koresha urufunguzo rwihariye na urufunguzo kugirango wirinde ibikoresho bidasanzwe bigira ingaruka kumyitozo.
(7) Mugihe ukoresheje imyitozo yingaruka, ibuka kudakoresha imbaraga nyinshi cyangwa kuyikoresha. Witondere neza neza imyitozo mbere kandi uhindure igipimo cyimbitse cyimyitozo. Igikorwa gihagaritse kandi kiringaniye kigomba gukorwa buhoro kandi buringaniye. Nigute ushobora guhindura imyitozo bito mugihe bigira ingaruka kumyitozo y'amashanyarazi n'imbaraga, ntukoreshe imbaraga nyinshi kuri bito.
