The preparation work before using the full hydraulic drilling rig is as follows:

1) Check whether the connection of each oil pipe is reliable;

2) Check whether the installation of the column is firm and reliable;

3) Check whether the hydraulic oil in the oil tank is added to the specified position and whether the filter is blocked. When the new machine is started, when the pump station is working, the hydraulic components are filled with oil to reduce the oil level, and then the oil should be filled in the oil tank
