Precautions
1. Pay attention to eliminate potential safety hazards. Care should be taken to eliminate safety hazards during the overhaul, such as: adjusting the clearance of the brake, replacing the worn clutch friction plate and making the seat of the cab easy to adjust up and down, as well as eliminating some injuries that may cause driving and maintenance personnel and machine malfunction Security risks. Strengthen the driver's labor protection awareness. When conducting the test of the machine's danger, there should be sufficient space and protective facilities around (for example: the excavator engine is prone to disintegrate and hurt people during the maximum load operation test).
2. The technical performance test after maintenance shall be carried out. The repair quality of mechanical equipment is the main indicator to measure the maintenance level, and is the key to whether the user is satisfied and the repair unit can survive and develop. The basis for testing the technical performance of mechanical equipment is "Machinery Management Standards", "Mechanical Quality Standards" and the main technical parameters provided by the original manufacturer. After the overhaul, the mechanical equipment should be tested for technical performance and given an overhaul evaluation. For the repaired factory equipment, if the repair quality problem occurs during the correct use, the excavator repair manufacturer should promptly provide on-site service to solve the user's worries.
3. Follow up service after overhaul. Establish a maintenance file for overhauling construction machinery, and the repair unit shall ensure that the repaired construction machinery can reach the specified performance and good use status within a certain period of time. If a general failure occurs within this time limit and can be eliminated after adjustment, it shall be resolved by the user. Such as due to major changes. When the machine parts are damaged, serious oil leakage, water leakage, gas leakage and electric leakage must be disassembled for repair, the repair unit should be notified to the repair unit for joint inspection and timely repair to reduce downtime and make The machine can work in good condition as much as possible.
