2. Igitanda cy'imashini gikozwe mu buryo bwa aluminiyumu bufatanye, kandi hejuru y'ameza hatunganywa byose hamwe;

3. Uburyo bwo kuzingira bukoresha silinda nk'isoko y'amashanyarazi n'agakoresho ko kohereza ibikoresho, kandi byihuse kandi byizewe. Ifumbire izingira ishobora guhindurwa n'intoki mu burebure kugira ngo ihuze n'imiyoboro ya aluminiyumu ifite uburebure butandukanye bwo hanze. (Igenwa hashingiwe ku bishushanyo by'ibicuruzwa)

4. Inguni ipfunyika ishobora guhindurwa n'intoki;

5. Bikwiriye gukoreshwa mu miyoboro ya aluminiyumu ifite umurambararo wa 8mm

6. Imiterere y'ibikoresho: Bigizwe ahanini n'intebe yo gukoreraho, igikoresho cyo gukurura umwuka, igikoresho cyo kuzingira n'igikoresho cyo kugenzura amashanyarazi.
