1. When the excavator is working, it should be parked on the solid and flat ground. The outrigger should be propped up well.
2. When the excavator is working, it should be in the horizontal position and the traveling mechanism should be braked. If the ground is muddy, soft and in danger of subsidence, sleepers or planks should be used.
3. When digging the bucket, the soil should not be too deep each time, and the bucket should not be lifted too hard, so as to avoid damaging the machinery or causing overturning accidents. When the bucket falls, be careful not to impact the track and frame.
4. The excavator must cooperate with the working personnel in the slope cleaning and bottom repairing. If it is necessary to work within the turning radius of the excavator, the excavator must stop turning and stop the turning mechanism before it can work. At the same time, the on-board and off-board personnel should take care of each other and cooperate closely to ensure safety.
5. Vehicles and pedestrians are not allowed to stay in the loading range of excavator. If unloading to the car, should wait for the car to stop, after the driver left the cab, can turn the bucket, unloading to the car. When the excavator rotates, try to avoid the bucket from the top of the cab. When unloading, the bucket should be lowered as far as possible, but attention should be paid not to collide with any part of the car.
