Maintenance Tips
-
Run Weekly Exercise Cycle
Ensure automatic self-test runs (≈20–30 minutes) to keep engine lubrication and system readiness optimal.
-
Change Oil & Filters Regularly
Follow scheduled oil, oil filter, and air filter changes to protect the industrial-grade KOHLER engine and extend service life.
-
Inspect Battery & Charging System Monthly
Check voltage, terminals, and corrosion to guarantee fast automatic startup during outages.
-
Monitor Fuel System (Natural Gas / Propane)
Verify fuel pressure, regulators, and line integrity for stable 3-phase load performance.
-
Clean Air Intake & Enclosure
Keep vents and enclosure free from dust and debris to maintain cooling efficiency and prevent overheating.
-
Test Under Load Periodically
Simulate real-world demand to confirm stable 3-phase voltage output and motor-starting capability.
-
Use App Connect Monitoring
Track alerts, runtime data, and system status remotely for proactive maintenance and faster troubleshooting.
-
Inspect Electrical Connections
Tighten and verify terminals, breakers, and transfer switch connections to ensure safe high-capacity operation.
-
Check Spark Plugs & Filters
Replace worn components to maintain fuel efficiency and clean combustion performance.
