2. Check whether the hydraulic pipeline is unobstructed, whether there is aging and leakage;
3. Check whether the pump works normally;
4. Check whether the pressure values of the hydraulic unit are normal; 7. Check whether the pressure gauge connector is loose; 8. Check whether the hydraulic components are damaged; electrical part
5. Clean the electric control cabinet;
6. Check whether the heat dissipation state of the electrical cabinet is good; 3. Check whether the wiring terminals in the electrical cabinet are firm;
