6. Ukugcinwa kunye noLondolozo kunye noFakelo kunye nokusebenza
6.1 Ivalve kufuneka igcinwe kwigumbi elomileyo nelingena umoya.
6.2 Iivalvu eziphantsi kogcino lwexesha elide kufuneka zihlolwe kwaye zicocwe rhoqo, ingakumbi indawo yokuhlala ukuze kuthintelwe ukonakaliswa kwayo, kwaye indawo yokuhlala kufuneka igqunywe nge-rust inhibiting oil.
6.3 Ukumakishwa kweValve makutshekishwe ukuhambelana nokusetyenziswa kwayo.
6.4 Umgodi wevalvu kunye nomphezulu wokutywina kufuneka uhlolwe phambi kofakelo kwaye kususwe ukungcola ukuba kukho.
6.5Icala lotolo kufuneka lifane nela ngakulo.
6.6 Ukuphakamisa ivalve yokujonga idiski emileyo kufuneka ifakwe ngokuthe nkqo kumbhobho.Ivalve yokujonga idiski ethe tyaba kufuneka ifakwe ngokuthe tye kumbhobho.
6.7 Ukungcangcazela kufuneka kujongwe kwaye utshintsho lwemibhobho yoxinzelelo oluphakathi kufuneka luqatshelwe ukuthintela ukusebenza kwamanzi.
