Gas generator sets are vital power equipment. After long hours of continuous operation, engines inevitably face wear, aging, and performance decline. Just like regular health check-ups for people, scheduled maintenance acts as a "physical exam" for engines—helping detect and resolve potential issues early, preventing small problems from becoming major ones, and ensuring your engine always operates at peak performance.

1. Replace Engine Oil and Filters

Engine oil is the "lifeblood" of the engine. Regular replacement of oil and filters minimizes wear, improves lubrication, and extends engine service life.

2. Inspect and Replace Spark Plugs

Spark plugs are crucial for igniting the fuel-air mixture. Routine inspection and timely replacement ensure reliable ignition, preventing hard starts, misfires, or unstable operation.

3. Clean and Inspect the Cooling System

The cooling system dissipates the heat generated during operation, keeping the engine within safe working temperatures. Regular cleaning and inspection help prevent blockages or leaks, protecting the engine from overheating damage.

4. Check and Adjust the Drive System

The drive system transfers engine power to the load. Periodic checks, adjustments, and replacement of worn components ensure optimal transmission efficiency and reduce energy loss.

5. Comprehensive Inspection and Fastening

Following the Liyu maintenance manual, a customized maintenance plan can be developed for each engine. Regular comprehensive inspections—including tightening loose bolts and nuts—help prevent component damage or detachment caused by vibration.
