6.Hanyoyin Aiki:
6.1 Aikace-aikacen Brush da Roller:
Idan aikace-aikacen goga da abin nadi na gama gari, zaɓi matakin HEC wanda ke ba da kyakkyawan juriyar goga/nadi da juriya.
6.2 Aikace-aikacen Fesa:
Don aikace-aikacen fesa, zaɓi matakin HEC wanda ke kiyaye kwanciyar hankali yayin atomization kuma yana tabbatar da ko da shafi.
7. Gwaji da Kula da inganci:
7.1 Ƙimar Lantarki:
Gudanar da cikakken gwaje-gwajen dakin gwaje-gwaje don tantance aikin ma'auni daban-daban na HEC a ƙarƙashin yanayin da ke kwatanta aikace-aikacen ainihin duniya.
7.2 Gwajin Fage:
Yi gwaje-gwajen filin don tabbatar da binciken dakin gwaje-gwaje da kuma lura da aikin HEC da aka zaɓa a cikin ainihin yanayin aikace-aikacen fenti.
8. Abubuwan Hulɗa da Muhalli:
