工作裝置未完全回收就行走
Walking without complete recovery of working device
工作裝置沒完全收回的情況下行走，挖斗很容易撞到巖石，油缸活塞桿會產生較大負荷，導致油缸內部破損以及銷軸周邊開裂。
When the working device is not fully retracted, the bucket is easy to hit the rock, and the piston rod of the oil cylinder will produce a large load, resulting in damage inside the oil cylinder and cracking around the pin shaft.
油缸桿伸縮到極限進行挖掘
The cylinder rod extends to the limit for excavation
液壓油缸伸縮到盡頭位置作業，這種情況下工作油缸、機架會產生較大的負荷，斗齒的沖擊、各個軸銷的沖擊，會造成油缸內部破損，還會影響其他的液壓部件。
The hydraulic oil cylinder is retracted to the end position for operation. In this case, the working oil cylinder and frame will produce a large load. The impact of bucket teeth and each axle pin will cause damage inside the oil cylinder and affect other hydraulic components.

履帶后部浮起做挖掘作業
The rear of the track floats for excavation
利用挖掘機車體后部上浮的力量來進行挖掘作業。當挖斗和巖石分開，車體下落時對挖斗、配重、機架、回轉支撐等產生較大的負荷，很容易造成損傷。
Use the floating force at the rear of the excavator body to carry out excavation. When the bucket is separated from the rock and the car body falls, it will produce a large load on the bucket, counterweight, frame and rotary support, which is easy to cause damage.
借助行走力挖掘
Excavation with walking force
液壓油混入水后容易乳化變質，乳化液壓油進入液壓系統會到導致零部件生銹。銹渣長期在液壓系統內流動，液壓壓力會受到影響，大小臂、挖斗動作會因此變得無力。
The hydraulic oil is easy to emulsify and deteriorate after mixing with water. The emulsified hydraulic oil entering the hydraulic system will lead to rust of parts. The rust slag flows in the hydraulic system for a long time, the hydraulic pressure will be affected, and the action of large and small arms and bucket will become weak.
挖機沒站穩就開工
The excavator started without standing still
路面不平整的石子路，在挖機未停穩的狀態下開始作業，長久下來會造成下車架受力不均，引起下車架受損。更好是在下方墊一些土，使地面平穩，這樣再作業。
For the stone road with uneven road surface, when the excavator is not stopped stably, the stress on the lower frame will be uneven and the lower frame will be damaged for a long time. It is best to pad some soil below to make the ground stable before operation.
