Whakanohoia te mowhiti piston ki roto i te rango, panaia te mowhiti ki te piston tawhito (i te huri i te mowhiti mo nga whakatikatika iti, pana ki te waahi ka neke te mowhiti o muri ki te waahi iti), me te ine i te waahi tuwhera me te matotoru. mehua.

Mena he iti rawa te waahi tuwhera, whakamahia he konae pai hei konae iti ki te pito tuwhera. Me mahi tirotiro auau i te wa e whakatika ana i nga konae kia kore ai e nui rawa te whakatuwheratanga, kia papatahi te whakatuwheratanga. Ina katia te whakatuwheratanga mowhiti mo te whakamatautau, kaua e paheke; ko te mutunga o te konae me kore he putea.

Tirohia te whiu whakamuri, kuhua te mowhiti piston ki roto i te riu mowhiti ka huri, ka ine i te aputa ki te ine matotoru me te kore e whakaputa titi. Mena he iti rawa te waahi, tuu te mowhiti piston ki runga i te pereti papatahi kua hipokina ki te kakahu emery, he pereti karaihe ranei kua hipokina ki te kirikiri kare ka huri kikokore.

Tirohia te whakamuri ka maka te mowhiti piston ki roto i te riu mowhiti, he iti iho te mowhiti i te peeke riu, ki te kore me huri te riu mowhiti ki te waahi tika.
