Generator Routine Inspections:
Preventative Maintenance for Reliable Performance

Routine generator inspections are essential for ensuring reliable operation, reducing the risk of unexpected failures, and extending the lifespan of your backup power system. Regular inspections help detect minor issues before they become costly repairs, keeping your generator in peak condition and ready to power your business during an outage.

​

Why Are Routine Generator Inspections Important?

• Prevents Unexpected Failures: Identifies potential issues early to avoid costly breakdowns.

• Ensures Reliable Startup: A well-maintained generator starts instantly when needed.

• Extends Generator Lifespan: Regular maintenance reduces wear and tear on critical components.

• Improves Fuel Efficiency: Clean and well-functioning parts optimize fuel consumption.

• Reduces Repair Costs: Addressing minor issues early prevents major repairs.

​

How Often Should You Perform Routine Generator Inspections?

The frequency of inspections depends on usage, environmental conditions, and manufacturer recommendations:

• Weekly: Quick visual inspection and system check.

• Monthly: More detailed inspection, including battery and fluid levels.

• Quarterly: Comprehensive inspection with testing and minor maintenance.

• Annually: Full-service maintenance, including load testing and part replacements.

Essential Steps for Routine Generator Inspections

1. Visual Inspection

A thorough visual check helps identify visible signs of wear or damage:
✔ Look for oil, fuel, or coolant leaks around the engine and hoses.
✔ Inspect belts and hoses for cracks, fraying, or looseness.
✔ Check for corrosion, rust, or physical damage on key components.
✔ Ensure the control panel and indicators are functioning properly.

2. Fluid Level Checks

Maintaining proper fluid levels ensures smooth operation and prevents overheating:
✔ Oil Level: Use the dipstick to check oil levels and color. Dirty oil indicates the need for an oil change.
✔ Coolant Level: Verify coolant levels in the radiator and top off if needed.
✔ Fuel Level & Quality: Ensure the fuel tank is adequately filled and inspect for contamination.

3. Battery Maintenance & Electrical System Check

A weak or faulty battery is a leading cause of generator failure:
✔ Inspect battery terminals for corrosion and clean if necessary.
✔ Check battery voltage with a multimeter (should be around 12.6V – 13.8V when fully charged).
✔ Ensure all electrical connections are secure and free of dirt.

4. Air & Fuel Filter Inspection

Dirty filters reduce efficiency and can cause performance issues:
✔ Inspect and replace clogged air filters to ensure proper airflow.
✔ Check fuel filters for blockages and replace if necessary.

5. Exhaust & Ventilation System Check

A clear exhaust system prevents dangerous fume buildup and overheating:
✔ Inspect the exhaust system for leaks, blockages, or damage.
✔ Ensure proper ventilation to avoid overheating.

6. Startup & Operational Testing

Running periodic tests ensures the generator functions properly under load:
✔ Start the generator and listen for unusual noises or vibrations.
✔ Observe for excessive smoke or unusual odors that could indicate engine issues.
✔ Check that the automatic transfer switch (ATS) properly transfers power during startup.
