Umkhiqizo ufakwe isistimu eqhutshwa ibhande eliqinisekisiwe kanye ne-crankshaft yamandla aphezulu, inganikeza amandla amahle kakhulu nokuqina, ukuhlangabezana nezidingo zabo bonke abavocavoca. Ikhava yezindlu eyenziwe ngepulasitiki, egcina izinkinga ohlakeni ngamanzi. Ukunethezeka kwezihlalo eziphezulu ngenxa yesimo se-ergonomic nesigqizekile sesihlalo. Isihlalo nesibambo kuyalungiseka ngobude nebanga. Ibhayisikili lokuzivocavoca linokuphepha, ubuhlungu okhalweni isikhathi eside nokunye. Ungakhetha indlela efanele yokuzivocavoca: ukuhlala nokuma. Bobabili bangasebenzisa ngokuphumelelayo imisipha yomlenze wakho, kanye namandla nokukhuthazela kwemilenze yakho, okuyinto enhle futhi ekukhuthazeni ukukhula kwamathambo. Uma ufuna ukwandisa imisipha yomlenze, kunconywa ukuthatha ukuzivocavoca kwamandla. Uma ufuna ukufeza umgomo wokunciphisa isisindo kanye namafutha avuthayo, kunconywa ukukhetha ukuzivocavoca okukhulu. Ngokuklama kokuhlola kwesayensi, ngokwamukela indlela yobunjiniyela bemishini yokwenziwa, ibhayisikili eliguquguqukayo lingahlangabezana nezidingo zomzimba womuntu, lingakhathazi okhalweni, kodwa futhi lenze ukufaneleka kufinyelele umphumela omkhulu. Kunezikhava ezimbili zezicathulo ezigxilile ku-pedal ngayinye ukuvimbela abantu bomzimba ukuthi bangaphonsa izinyawo zabo ngesikhathi sokuzivocavoca, ukunamathela kumqondo wokuklama ukuphepha.
1.Ibhayisikili lohlaka lwensimbi enokwakhiwa okuqinile.
2.Phezulu phansi nangemuva zonke izindawo ziyalungiseka.
3. Isibambo esinerabha esingasheleli esinezinketho zokubamba ezihlukene kanye nethreyi yesiphuzo esiphindwe kabili.
