Semi-Annual Maintenance

Maintenance programs enable us to find and correct minor problems before they become major problems. Scheduled maintenance does not guarantee you will never have a problem but it lessens the chances of problems occurring.

  • Note: Second service does not include oil and filter change or ignition parts.

Load Bank Testing

Hunter & Lomison offers load bank testing as an optional part of our yearly maintenance agreement. Load bank testing is an ideal way to ensure the integrity of your generator and prevent generator failure during an emergency.

Benefits of load banking your generator

  • Prevents moisture build up on internal parts.
  • Removes carbon and soot from cylinders, heads and exhaust system.
  • If done within the first year of service will help seat rings and other internal parts.
