Introduction
Weekly inspections of site generators are essential for ensuring continuous power supply, preventing costly downtime, and maintaining construction site productivity. This comprehensive checklist helps operators identify potential issues before they lead to generator failure, electrical hazards, or emergency power loss. A thorough weekly inspection not only ensures regulatory compliance but also maximizes fuel efficiency and extends the service life of your site generator.
Following this site generator inspection checklist as part of your weekly routine helps create a safer work environment, prevents unexpected power interruptions during critical project phases, and provides documentation for maintenance records. The checklist aligns with OSHA requirements, manufacturer specifications, and industry best practices for generator safety and maintenance in construction environments.

Pro Tips for Effective Generator Inspection
- Perform When Cool: Always conduct inspections when the generator is cool to avoid burns and ensure accurate fluid level readings. Schedule inspections before daily startup or after sufficient cooling time.
- Check for Load Changes: Verify if there have been any changes to the connected load since the last inspection, as overloading is a common cause of generator issues and reduced lifespan.
- Maintain Inspection Records: Keep detailed records of all inspections and maintenance activities. Historical data helps identify patterns of wear and potential problems before they cause failures.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of your site generator. Adapt these steps to your specific generator model and operating conditions.
Battery Inspection Procedure
- Ensure generator is off and disconnect starting circuit
- Inspect battery terminals for corrosion and tightness
- Check electrolyte level in non-sealed batteries
- Measure voltage with digital multimeter (12.6V fully charged)
- Clean terminals with battery terminal cleaner if needed
Fuel Quality Testing
- Draw fuel sample from lowest point in tank
- Check for water with water-finding paste on dipstick
- Inspect sample for clarity, color, and contaminants
- Test for microbial growth if fuel has been stored long-term
- Document fuel quality and take action if degraded
Load Bank Testing (If Available)
- Connect portable load bank to generator output
- Verify all connections are secure and properly sized
- Run generator at 25%, 50%, 75%, and 100% load for 15 minutes each
- Monitor voltage, frequency, and temperature at each load level
- Document readings and verify against specifications
Coolant System Inspection
- Check coolant level only when engine is cold
- Test coolant concentration with refractometer
- Inspect hoses by squeezing to detect softening or cracking
- Check radiator fins for blockage or damage
- Verify coolant pH level with test strips

Maintenance Guidelines
These guidelines outline recommended maintenance tasks to complement your weekly inspections. Following these schedules helps prevent generator failures and extends the service life of your site generator.
Weekly Maintenance
- Check all fluid levels (oil, coolant, fuel)
- Inspect battery connections and charge level
- Run generator under load for 30 minutes
- Check for fluid leaks and unusual noises
- Clean exterior of generator enclosure
Monthly Maintenance
- Check air filter condition
- Test automatic transfer switch (if equipped)
- Inspect exhaust system thoroughly
- Check belt tension and condition
- Verify all control functions
Quarterly Maintenance
- Change engine oil and filter
- Check cooling system and antifreeze protection
- Inspect starting system components
- Clean/replace fuel filters
- Conduct load bank test if available
Annual Maintenance
- Replace air filter element
- Change coolant and flush system
- Test protective relays and circuit breakers
- Inspect/clean generator windings
- Conduct comprehensive load test
Conclusion
