OPTIONAL FUNCTION

Generator Maintenance and Servicing
At XN-GEN, we offer long-term maintenance agreements to provide professional, high-quality, and hassle-free service for our customers. Our maintenance services ensure the optimal performance and longevity of your generator set. Below is a general guideline for maintenance procedures (please note that specific actions may vary based on the model and operational status of each generator set).
Routine Maintenance
Regular inspections and upkeep are crucial to ensuring the reliability of your generator. The following checks should be performed regularly:
- Inspect all rotating components and tighten any loose bolts.
- Check the oil level in the crankcase and add oil if necessary.
- Monitor fuel levels in the tank.
- Inspect the coolant level in the radiator.
- Examine fuel and water pipelines for any leaks or loose connections.
- Ensure the intake and exhaust systems, along with cylinder gaskets, are properly sealed.
- Clean any oil stains or dust accumulation on the generator to maintain a tidy machine room.
Maintenance Plan for Standby Generators
(Recommended for backup generators used in residential communities, commercial buildings, hospitals, government facilities, tourist attractions, factories, and other locations where power outages are rare.)
Professional Maintenance (Every Six Months or Annually)
In addition to routine maintenance, a comprehensive service should be performed every six months or once a year:
- Conduct a thorough inspection of the fuel, electrical, cooling, and lubrication systems to ensure proper functionality.
- Perform a no-load test run for 5-10 minutes to lubricate the system. Assess the generator's performance using auditory, visual, and olfactory checks.
- Replace consumable filters, including air, diesel, oil, water, and fuel-water separators.
- Drain and replace coolant, ensuring proper radiator function.
- Check and replenish the battery electrolyte or distilled water as needed.
- After completing the maintenance, conduct a final inspection and clean the generator set.
- Perform another 5-10 minute no-load test, record performance parameters, and provide optimization recommendations before customer acceptance.
Maintenance Plan for Continuous Operation Generators
(Recommended for generators in construction sites, frequently power-outage-prone factories, areas with insufficient transformer capacity, project testing sites, or locations without access to the main grid.)
Level 1 Maintenance (Every 50-80 Hours)
This includes all routine maintenance tasks plus:
- Clean the air filter and replace it if necessary.
- Replace the diesel filter, air filter, and water filter.
- Inspect the tension of the drive belt and adjust if needed.
- Lubricate all grease fittings and moving components.
- Replace coolant to maintain effective cooling performance.
Level 2 Maintenance (Every 250-300 Hours)
Includes Level 1 maintenance tasks, with additional checks:
- Clean and inspect pistons, piston pins, cylinder liners, piston rings, and connecting rod bearings for wear.
- Examine the main bearing for any signs of looseness or abnormal wear.
- Remove scale and sediment from the cooling system to ensure proper heat dissipation.
- Clear carbon deposits from the combustion chamber and intake/exhaust passages.
- Inspect and adjust valve clearances, valve seats, push rods, and rocker arms.
- Clean turbocharger rotors and check bearings and impellers for wear, replacing if necessary.
- Tighten or replace any loosened or damaged bolts in the generator-diesel engine coupling.
Level 3 Maintenance (Every 500-1000 Hours)
Includes Level 1 and Level 2 maintenance tasks, along with additional services:
- Check and adjust the fuel injection timing.
- Clean the fuel tank to remove contaminants.
- Clean the oil sump to prevent sludge buildup.
- Inspect and test the fuel injectors for optimal atomization.
By following this structured maintenance plan, generator owners can ensure consistent performance, increased lifespan, and reduced risk of unexpected failures. Our expert team at XN-GEN is dedicated to delivering superior service to keep your power supply reliable at all times.
