Air-Cooled Generator Service Checklist

This air-cooled generator service checklist helps technicians standardize preventive maintenance and document results. Steps include changing oil and oil filter, replacing the air filter, and setting spark plug gaps with model-specific guidance for Kohler and Generac units. It covers battery load testing, charger output checks, and validation of voltage and frequency. The checklist prompts review of on-screen faults, notes issues found, and verifies auto-start by isolating utility power and confirming start, load transfer, and proper shutdown on restoration. Technicians inspect wiring and tubing for wear, check the engine, enclosure, and connections, and test gas lines for leaks. Final steps confirm the unit is in Auto with a green indicator, record overall condition, and capture signature for closeout.
