Thanthwe limagwira ntchito molingana ndi mfundo zophwanya.
Mukamagwira ntchito, piston imapangitsa kuti gulu lonse loyenda bwino lizisintha, limakhumudwitsa.
Mothandizidwa ndi gulu lamphamvu, kubowola kowoneka bwino kwambiri kumagwedezeka mwalawo ndikuyatsa pang'ono, ndikupanga dent.
Pambuyo pisitoni imabweza, kubowola kumazungulira mbali ina ndi pistoni kumapita patsogolo.
Pamene shank imagundanso, mawonekedwe atsopano amapangidwa. Chovala chowoneka bwino pakati pa ma dents awiri chimadumphadumpha ndi mphamvu yopingasa yomwe imapangidwa pang'onopang'ono.
Piston mosalekeza imasokoneza mchira wa kubowola ndi zosintha mosalekeza zimapanikiza mpweya kapena madzi okakamiza kuchokera pa bowo la kubowola kuti atuluke pa bowo, ndikupanga dzenje lozungulira ndi kuya kwakuya ndi kuya kwakukuru.
