Maintenance Tips

• Oil changes are critical: First at ~25 hours, then every 50–100 hours (10W-30 oil). Large V-twin engine needs clean oil for long life.
• Run monthly under load: Keeps engine seals lubricated, battery charged, and fuel system ready for emergencies.
• Use fresh gasoline only: Stale fuel causes carburetor clogging—drain fuel for long storage periods.
• Clean air filters regularly: Check every 25–50 hours, more often in dusty environments to maintain airflow and power stability.
• Inspect spark plugs: Replace or clean periodically for reliable starting and smooth performance under heavy load.
• Keep CO sensor active: Never disable it—ensure outdoor ventilation for automatic shutdown protection.
• Avoid overload: Stay within 20,000W running / 28,000W peak to prevent voltage drops and alternator strain.
• Battery maintenance (remote start): Keep fully charged; weak batteries are a common cause of failed electric/remote starts.
• Check fuel system & connections: Ensure no leaks and that fuel lines remain clean and secure, especially after storage.
• Keep unit clean & dry: Protect from dust, moisture, and corrosion; store in a ventilated covered area.
