Excavators need to pay attention to the following points:

Check before operation to make sure that everything is complete and intact, there are no obstacles and other personnel within the movement range of the big arm and the bucket, and the operation can be carried out after the siren warning.

When digging, the soil should not be too deep each time, and the bucket should not be too fierce, so as not to damage the machinery or cause overturning accidents.

When the bucket falls, be careful not to impact the track and frame.

Vehicles and pedestrians shall not be stopped within the loading range of the excavator.

When the excavator is rotating, the rotary clutch and the rotary brake are used to rotate smoothly, and sharp rotation and emergency braking are prohibited.

Before the bucket leaves the ground, it is not allowed to do rotating, walking and other actions. When the bucket is fully loaded and suspended, it shall not lift up or down the arm rod and walk.

When the crawler excavator moves, the arm rod should be placed in the forward direction of the walk, and the height of the bucket from the ground should not exceed 1 meter. And brake the rotating mechanism.
