Isibambo esimise okwe-L senza isikrufu sibe lula ukusibamba nokusebenza, sinikeze ukudluliswa kwamandla amakhulu. Kungakhathaliseki ukuthi izikulufu eziqinisayo noma ezikhululayo, izikrufu zebhola ezimise okwe-L zingabhekana kalula nezimo ezihlukahlukene zomsebenzi.
Isiphetho sethiphu yebhola singazungeziswa ngama-engeli amaningi, okukunikeza ukuguquguquka okwengeziwe ukuze ulungise indawo ye-wrench ukuze kufakwe ama-engeli ahlukene nezikulufu okunzima ukuzifinyelela. Lo mklamo ungathuthukisa ukusebenza kahle komsebenzi futhi unciphise ukusebenza kanzima.
