What are the precautions for the maintenance and repair of small excavators?

Maintenance and upkeep of small excavators is crucial to ensure their efficient operation for a long time. First, regular inspection and replacement of oil, hydraulic oil and air filters is necessary to maintain the normal operation of the engine and hydraulic system. Second, pay attention to cleaning coolers and radiators to prevent overheating. Regularly inspect and tighten bolts, chains and other critical parts to prevent failure due to wear and tear of parts. At the same time, keep the hydraulic system clean to prevent impurities from entering the system and affecting normal operation. Finally, operators should receive regular training, familiar with the use of excavators, and pay attention to safe operation to reduce wear and tear and extend the life of equipment.
