安裝長(cháng)螺旋鉆桿后，電源頻率和控制箱中頻率開(kāi)關(guān)上的指針應顯示相同的比率。如果它們不同，則應使用變頻開(kāi)關(guān)進(jìn)行轉換。鉆桿安裝在鉆機上。鉆機的放置應穩定，牢固，挺桿應通過(guò)自動(dòng)微調或鋼絲錘進(jìn)行調節，以保持其垂直狀態(tài)。在開(kāi)始螺旋鉆桿操作之前，應將操縱桿調節至中性位置。在使用鉆桿的過(guò)程中，如果發(fā)現向下鉆取極限警報信號已打開(kāi)，則必須及時(shí)停止鉆削，并將鉆桿提升至一定高度，等待直到警報信號消除，然后您才能使用可以繼續進(jìn)行鉆桿工作。在操作過(guò)程中，當需要改變螺旋鉆桿的旋轉方向時(shí)，必須等到鉆桿安全停止后再繼續操作。
