Intambwe zihariye zo gusimbuza idirishya ryo hanze ni nkibi bikurikira:
Tegura ibikoresho uzakenera kugirango ukureho idirishya ryose rya trim, icyuma gito, icyuma kinini, na t-20 umugozi
Habonetse igifuniko gito cy'umukara ku ruhande rw'umuryango, washyizaga imigozi hanze y'idirishya, ugakuramo icyuma gito, hanyuma ugakoresha icyuma gito kugira ngo ugabanye igifuniko gito cy'umukara hasi, witondere kuba urumuri igihe usenga, ntukureho irangi ry'umuryango, hanyuma ushireho igifuniko gito cy'umukara hasi.
Byabonetse imbere muri screw ifata hanze yidirishya, fata umurongo wa t-20, hanyuma ukoreshe umugozi wa t-20 kugirango ukureho iyi screw.
Gusenya ibice byo hanze. Kuramo icyuma kinini, koresha icyuma kinini kugirango ukoreshe buhoro buhoro inkombe yidirishya hanze yumubari, kugirango idirishya hanze yumubari rirekure. Koresha urutoki rwawe kugirango ufate idirishya hanze yumubari, hanyuma witonze hejuru, buhoro buhoro idirishya hanze yumubari ritandukanijwe nuruhande rwumuryango, menya buhoro buhoro, buhoro buhoro kumeneka, imbaraga nyinshi, biroroshye guhindura idirishya hanze yumubari. Batten yo hanze rero yakuweho neza.
Ubukurikira ushyireho bundi bushya.
