自動怠速
當停止所有操作裝置動作4秒后，發動機自動轉換為怠速運轉，再次操作，發動機立即恢復至原先轉速。采用自動怠速，可有效節省燃油。夜間在市區內作業，也不會干擾周圍環境。
無尾回轉，動臂側移
動臂側移、無尾回轉，兩大功能同時擁有，助您應對復雜環境，無障礙施工。
三泵液壓系統
●H·M·S液壓系統，動臂、斗桿、回轉采用各自獨立的3泵系統，配置了控制范圍更廣的控制閥、變量泵。實現了快速順暢而又強力的作業。
●配備直行前進回路，行走時，即使操作動臂也不會出現S形，速度也不會改變，因而可實現穩定的直線行駛。
●可實現四聯動，通過3泵液壓系統，可實現鏟斗、動臂、斗桿、回轉的同時操作。向翻斗車的裝載作業等也快捷、順暢。
