2. Chikwatu chokhazikika cha hemmer ya pansi pa chovalachi chikugwirizana ndi m'lifupi kuyambira 9 mpaka 30 mm, ndipo mafoda apadera osankha amatha kufikira 42 mm.
3. Makina osokera okha m'mphepete mwa m'munsi ali ndi njira yotsegulira yolumikizirana ndi pneumatic ya makina ake otsogolera.
4. Dongosolo la pneumatic la chipangizo chozungulira pansi chomwe chimagwiritsa ntchito makina onse odziyimira pawokha limapereka njira zosankhidwa ndi manja kapena zodziyimira zokha kuti zigwiritsidwe ntchito mosavuta.
5. Makina osokera omwe amapinda pansi pa nsalu amalola kunyamula mapazi nthawi imodzi panthawi yonse yosokera.
6. Pa makina osokera zovala pansi pa m'mphepete mwa zovala awa, kutalika kwa kusoka kwamagetsi kumatha kukhazikitsidwa mosavuta kudzera pa gulu lowongolera kuti zikhale zosavuta komanso zomasuka.
7. Mbali iliyonse ya zida zathu, kuphatikizapo makina osokera omwe amangogwira ntchito pansi pa m'mphepete, adapangidwa kuti awonjezere kugwira ntchito bwino komanso kuchepetsa kutopa kwa ogwiritsa ntchito panthawi yayitali.
