The basic operation of the hydraulic crawler excavator is as follows:
1. Make sure there are no obstacles around the excavator. Just like learning to drive, first observe the surrounding vehicle conditions;
2. After getting on the bus, sound the horn first to warn passers-by and also serve as a safety warning;
3. Confirm that there is no alarm on the instrument and there is no abnormality in the vehicle;
4. Turn the cut-off valve to ON to start; the specific operation is divided into four actions: big arm, small arm, bucket, rotation. Some small machines also have a push shovel.
Now let’s talk about the situation in the cab. There are two operating handles in the cab: the left handle has two actions: rotation and forearm; the left and right handles the left and right optional functions, and the front and rear handles extend the forearm. . The handle on the right has two actions: the bucket and the arm. The left and right ones are used to retract the bucket, and the front and back are used to raise and lower the arm. There are two in front that can only be used forward and backward; It is used for chain rail walking. These are the most basic operations, which can usually be remembered in about an hour. The most important thing is that the chain movements require long-term practice and you will slowly become familiar with them. If you want to learn the excavator well, you must have patience.

Basic knowledge
1. Brand new excavators are fixed assets with heavy economic investment. In order to extend their service life and obtain greater economic benefits, the equipment must be assigned personnel, machines, positions, and clear responsibilities. When it is necessary to transfer positions, equipment disclosures should be made.
2. After the excavator enters the construction site, the driver should first observe the geology of the working surface and the surrounding environment. There should be no obstacles within the excavator's rotation radius to avoid scratches or damage to the vehicle.
3. After the machine is started, no one is allowed to stand in the bucket, on the shovel arm or on the track to ensure safe production.
4. When the excavator is working, no one is allowed to stay or walk within the radius of rotation or under the bucket. Non-drivers are not allowed to enter the cab and move around, and are not allowed to train drivers to avoid damage to electrical equipment.
Excavator operating sequence:
1. Inspection and preparation;
2. Empty machine test run;
3. Start up and install rocks;
4. Shut down.
Its normal operation is:
1. Before starting the machine, surrounding personnel should be evacuated outside the working range of the excavator; 2. During the rock loading process, large pieces of gangue must be smashed with a sledgehammer. Gangue larger than 300mm is not allowed to be loaded into the truck;
3. Pay attention to the two sets of shed legs, bone piles and temporary supports to prevent scratches;
4. It is strictly forbidden to use rock machines to erect scaffolding
