Tha slat 1.Polish na sheòrsa de shlat suirghe sònraichte ceangailte ri slat sucker agus crochadair beam. Tha e aig mullach slat sucker, feumar an neart as motha a ghiùlan, mar sin le trast-thomhas nas motha agus ìre stàilinn nas àirde na slat suidse, agus tha an uachdar gu math rèidh.
2.Main gnìomh:
Còmhla ri seata pacaidh ann am bogsa pacaidh gus ceann tobair a ròn agus casg a chuir air ola, gas, foillseachadh uisge.
Ceangal eadar-amail eadar slat suirghe agus crochadair ceann muile
Crìochnachadh deuchainn sgeama comharran.
Cuir crìoch air diofar obrachadh ceann tobair, leithid bualadh pumpa, riaghladh suidheachadh pumpa.
