1.新机使用初期的保养(1)使用前,各部分液压缸应空载运行几次,以排除内部可能存在的空气,避免工作过程中产生振动和爬行;并检查空载时落臂或缩臂的系统压力。(2)在使用100h之内,工作的负荷不宜过大、速度不宜过高,避免起吊最大负荷;调好油门限位装置,使液压泵转速不超过其额定转速。
1. The initial maintenance of the new machine (1) before use, all parts of the hydraulic cylinder should be run a few times to eliminate the possible internal air to avoid vibrations and crawling during work; and check the no-load arm or System pressure of boom. (2) within 100h, the work load should not be too large, the speed should not be too high, to avoid lifting the maximum load; adjust the throttle limit device so that the hydraulic pump speed does not exceed its rated speed.
