Before using the C-steel equipment of the 80-300 full-automatic hydraulic motor, check whether the connections are secure everywhere, install the bolts, and whether the nuts are tightened. The hydraulic motor casing must be filled with hydraulic oil to prevent damage before the machine can be powered on and tested. First, carefully observe the empty car operation, whether there is vibration, noise, whether oil is coming from the oil window, and whether the movement of each component is coordinated. Only after everything is normal can you start working. Strictly ensure the cleanliness of the connecting oil port, and do not allow solid foreign objects to enter; reducing the radial load on the

output shaft of the hydraulic motor can extend the life of the hydraulic motor
