Incazelo emfushane:

Uhlobo lwe-YT27 uhlobo lomoya wezinyawo uhlobo lomshini we-chisel rock osebenza kahle uhlobo olukhanyayo, olulungele uhlobo olumanzi lokuprakthiza kanye ne-chisel phansi bese ugoba izimbobo emadwaleni aqinile noma aqinile (f = 8-18). Ububanzi be-chisel hole 34-45mm, ukujula kwemigodi evumayo kufinyelela ku-5m. Inezimpawu zomsebenzi womgodi oqinile wokushaywa kwegobongo, umzuzu wokukhetha omkhulu ojikelezayo, amathuluzi edwala le-chisel asetshenziswa kakhulu kujantshi, ukongiwa kwamanzi, iphrojekthi yokuvikela izwe, ukusetshenziswa kwe-assort nge-FY250 yohlobo lokugcwalisa uwoyela nohlobo lwe-FT160A (noma i-FT160B) , ngokusobala ingcono kunemikhiqizo yohlobo olufanayo.
