Ikhethekileyo ukuphuhlisa amandla aphezulu kunye nesikrufu esikhethekileyo sealloy, qinisekisa ukuba ubomi obuluncedo koomatshini buya kuba bubude. Ukuxhobisa iipaseji ezimbini zangaphambili zokutofa imoto yetekhnoloji ekhokelayo, kunokuqinisekisa ukuba isikrufu sondla ngakumbi kwaye ngokukhawuleza ngetorque enkulu, ukuze mre iphucule umthamo weplastiki. Ukwamkela esona sicwangciso sifanelekileyo, esinje ngeepaseji zeoyile ye-enlagre kunye nomngxuma woomatshini bokutya, qinisekisa uzinzo kunye nesantya xa sisebenza kunye nesitokhwe seshiti, ukutyumza okanye izixhobo zomlomo.
