Detailed Inspection Procedures

Follow these step-by-step procedures for key inspection areas on your site generator to ensure thoroughness and proper maintenance. Adapt these procedures to your specific generator model and operating conditions.

Visual Inspection & Environment

Ensure generator is off and properly cooled before inspection
Check for debris, leaves, or objects in generator housing
Inspect for rodent or pest intrusion and damage
Verify air intake and exhaust areas are clear and unobstructed
Check for fluid leaks around generator and containment area
Inspect generator mounting for stability and vibration issues
Check weather protection systems if generator is outdoors
Verify ventilation is adequate and not blocked
Check corrosion on external parts, particularly in coastal areas
Ensure appropriate clearance around generator per specifications

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
Check battery cable condition for wear or damage
Verify battery securing mechanism is tight
Test battery load capacity with appropriate tester if available
Inspect battery casing for cracks or damage
Record battery readings and compare to previous inspections

Fuel System Inspection

Check fuel level in tank and record percentage
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
Inspect fuel lines for leaks, kinks, or damage
Check fuel filters and change if required
Verify fuel pump operation during test run
Inspect fuel tank for rust or contamination
Check fuel cap seal for proper condition

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
Inspect water pump for leaks or unusual noise during operation
Check coolant reservoir cap for proper sealing
Verify coolant is appropriate type for your generator
Inspect fan belts for tension and wear
Check for coolant leaks at all connection points

Engine & Lubrication System

Check engine oil level with dipstick when cold
Inspect oil condition for discoloration or contamination
Check for oil leaks around filter, pan, and seals
Verify oil filter condition and replacement schedule
Inspect all belts for tension, wear, and alignment
Check belt tensioner bearings for smooth operation
Inspect engine for unusual deposits or corrosion
Verify all hose connections are secure
Listen for unusual engine noises during test run
Check engine air filter and clean/replace as needed

Electrical System Inspection

Verify all electrical connections are clean and tight
Inspect control panel for proper operation and displays
Check all indicator lights and alarm systems
Inspect wiring for damage, wear, or heat discoloration
Test emergency shutdown systems for proper operation
Verify automatic transfer switch functionality if equipped
Check output voltage and frequency under no load
Inspect circuit breakers and fuses for proper condition
Test ground connection for integrity and resistance
Verify battery charger operation if equipped

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
Check for unusual noises or vibrations under load
Monitor exhaust color for abnormalities
Verify generator stability at peak load
Check for any alarms or warnings during testing
After test, verify generator properly cools down

Documentation & Reporting

Record all inspection findings in maintenance log
Document generator run time hours from meter
Note any abnormalities or issues found during inspection
Update service schedule based on hours and manufacturer requirements
Verify emergency contact information is current and visible
Check that operating instructions are accessible
Update inventory of spare parts and filters
Document fuel consumption rates if measured
Tag any components needing repair or replacement
File inspection report in compliance with site requirements

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.
Listen Carefully: During test runs, a trained ear can detect problems before they appear on gauges. Unusual sounds like knocking, pinging, or excessive vibration can indicate developing issues.
Weather Considerations: Adjust inspection focus based on seasonal conditions - check for freezing issues in winter, cooling efficiency in summer, and corrosion/water intrusion during rainy seasons.

Critical Safety Guidelines

Lock Out/Tag Out: Always follow proper lock out/tag out procedures before performing inspection or maintenance to prevent accidental startup. Disconnect battery negative terminal first for additional safety.
Exhaust Hazards: Never run generators in enclosed spaces without proper ventilation systems. Carbon monoxide from exhaust can cause serious injury or death. Verify exhaust systems are properly vented outdoors.
Fuel Safety: Never smoke or have open flames near the generator during inspection or refueling. Clean up any fuel spills immediately and dispose of fuel-soaked materials properly.
Electrical Safety: Use appropriate PPE including insulated tools and rubber gloves when working with electrical components. Never touch electrical parts when generator is running or immediately after shutdown.
Environmental Compliance: Ensure all waste fluids are collected and disposed of according to local environmental regulations. Use appropriate containment systems to prevent soil or water contamination.

Conclusion

Implementing a comprehensive weekly inspection program for your site generators is essential for ensuring reliable power, preventing costly breakdowns, and extending equipment life. By following this systematic inspection procedure, site managers can identify and address potential issues before they lead to generator failures or emergency situations.

For optimal inspection management and documentation, consider implementing the HVI APP (Heavy Vehicle Inspection and Maintenance software) to digitize your generator inspection process. The HVI platform allows for streamlined documentation of weekly inspections, automatic scheduling of maintenance activities, and comprehensive historical records that help identify trends before they become problems.

With the Heavy Vehicle Inspection and Maintenance software, site managers can easily monitor generator inspection compliance, track maintenance history, and ensure all generators are properly maintained according to manufacturer specifications. This digital approach not only improves inspection quality and consistency but also significantly reduces administrative burden while protecting your critical power infrastructure.
