Generator Preventative Maintenance Service

Help ensure your standby generator is ready to operate when utility power is lost with professional generator preventive maintenance.

Standby generators may sit unused for extended periods, but they must start quickly and operate reliably when an outage occurs. Routine inspection, testing, and engine maintenance can help identify developing problems before they prevent the generator from starting or carrying the required load.

Generator maintenance can be provided as a one-time service or scheduled annually, semiannually, or at another interval based on the equipment, operating hours, application, and facility requirements.

Typical Scope of Service:

A generator preventative maintenance visit may include:

• Visual inspection of the generator and surrounding equipment
  
• Review of controller alarms, fault history, and operating hours
  
• Inspection of the engine, alternator, controls, wiring, and accessible connections
  
• Inspection for fluid leaks, loose connections, corrosion, damage, or excessive wear
  
• Verification of engine oil and coolant levels
  
• Inspection of belts, hoses, clamps, and cooling-system components
  
• Inspection of air, oil, and fuel filters
  
• Inspection of the fuel system and accessible fuel connections
  
• Inspection and testing of the starting batteries
  
• Verification of battery-charger operation
  
• Inspection of the exhaust system
  
• Review of block-heater operation
  
• Verification of generator voltage, frequency, and operating readings
  
• Generator start and operational exercise
  
• Automatic transfer switch inspection and testing when included
  
• Written service report documenting system condition, findings, and recommendations
  

Oil, coolant, filters, spark plugs, starting batteries, and other maintenance materials may be replaced when included in the service proposal.

• Help ensure the generator is prepared to support critical loads
  

Service Options:

Generator preventative maintenance can be customized to include:

• One-time maintenance service
  
• Annual, semiannual, or quarterly maintenance
  
• Diesel, natural-gas, or propane generators
