挖掘时每次吃土不宜过深,提斗不要过猛,以免损坏机械或造成倾覆事故。挖斗下落时,注意不要冲击履带及车架。挖掘机装载活动范围内,不得停留车辆和行人,若往汽车上卸料时,应等汽车停稳,驾驶员离开驾驶室后,方可回转挖斗,向车上卸料。
When digging, the soil should not be too deep at the time of excavation, and the bucket should not be too fierce to avoid damaging the machinery or causing overturning accidents. When the bucket falls, pay attention not to impact the track and frame. During the loading range of the excavator, the vehicle and the pedestrians should not be stopped. If the vehicle is discharged from the car, the car should wait for the car to stop. After the driver leaves the cab, the dug can be turned and unloaded to the car.
挖掘机挖斗未离开地面前,不得做回转、走行等动作。挖斗满载悬空时,不得起落臂杆和行走。履带式挖掘机移动时,臂杆应放在走行的前进方向,挖斗距地面高度不超过1米。并将回转机构刹住。
If the excavator of the long arm excavator does not leave the ground, it must not make any movements such as turning and walking.

挖掘机在高的工作面上挖掘散粒土壤时,应将工作面内的较大石块和其他杂物,以免塌下造成事故。若土壤挖成悬空状态而不能自然塌落时,则需用人工处理,不准用挖斗将其砸下或压下,以免造成事故。
