Before replacing the parts, some maintenance personnel do not perform technical inspections on the new parts and directly install them on the construction machinery. This is unscientific. At present, the quality of spare parts sold on the market is uneven, and some counterfeit and shoddy parts are mixed with beads; some accessories have changed performance due to excessive inventory time. If they are not tested, they often cause failure after assembly.
Be sure to carry out the necessary inspections and tests before replacing the new parts. The tests include appearance and performance tests to ensure that the new parts are not faulty and prevent unnecessary troubles.
