matters needing attention
1. Pay attention to eliminate potential safety hazards. During the overhaul, pay attention to eliminate potential safety hazards, such as adjusting the clearance of the brake, replacing the worn clutch friction plate, making it easy to adjust the seat in the cab up and down, and eliminating some potential safety hazards that are easy to cause injuries to drivers and maintenance personnel and machine failures. Strengthen the driver's awareness of labor protection. During the dangerous experiment of the machine, enough space and protective facilities shall be left around (for example, the excavator engine is easy to break up and hurt people during the maximum load operation experiment).
2. The technical performance test after maintenance shall be carried out. The repair quality of mechanical equipment is the main index to measure the maintenance level. It is the key to the satisfaction of users and the survival and development of repair units. The technical performance test of mechanical equipment is based on the mechanical management specification, mechanical quality standard and the main technical parameters provided by the original manufacturer. Technical performance test shall be conducted for mechanical equipment after overhaul, and overhaul evaluation shall be given. For the repaired mechanical equipment, in case of repair quality problems during correct use, the excavator maintenance manufacturer shall provide door-to-door service in time to solve the problems for users.
3. Follow up service after overhaul. The maintenance archives of overhauled construction machinery shall be established, and the repair unit shall ensure that the repaired construction machinery can reach the specified service performance and good service condition within a certain period of time. Within this period, if a general fault occurs and can be eliminated after adjustment, it shall be solved by the user. For example, due to major changes. When the main parts must be disassembled for repair due to damage of mechanical parts, serious oil leakage, water leakage, air leakage and electric leakage, the repair unit shall notify the repair unit to jointly inspect and repair in time, so as to reduce the shutdown time and keep the machine in good condition after overhaul as far as possible.
