Maintenance Tips
-
Change engine oil regularly: First at ~25 hours, then every 150–250 hours or annually using manufacturer-approved oil to ensure stable 30kW standby performance.
-
Check oil level daily (before run/exercise): Prevents low-oil shutdown and protects the liquid-cooled gaseous engine.
-
Replace air filter periodically: Keeps intake clean for efficient combustion and stable voltage output under load.
-
Inspect spark plugs & ignition system annually: Ensures reliable starting on natural gas or propane operation.
-
Maintain coolant system (liquid-cooled): Check coolant level, hoses, and radiator for leaks or blockage to prevent overheating.
-
Clean enclosure & airflow paths: Sound-attenuated housing must remain free of debris for proper heat dissipation.
-
Run monthly exercise cycle under load: Keeps engine lubricated, fuel system active, and electronics healthy (reduces startup failure risk).
-
Inspect battery system: Check terminals and charge level—battery health is critical for automatic standby start.
-
Check fuel system (NG/LP): Inspect regulators, lines, and fittings for leaks or pressure irregularities.
-
Review control panel alerts: PowerCommand diagnostics help detect early faults before downtime occurs.
