Maintenance Tips

• Perform scheduled oil & filter changes per the owner’s manual to maintain engine health and longevity. Regular checks prevent premature wear.
• Run weekly or bi‑weekly exercise cycles with load (use App remote start) to burn off moisture and keep internal parts lubricated and ready.
• Inspect air intake, exhaust & enclosure surfaces to remove debris and ensure efficient cooling and combustion.
• Monitor battery condition & connections—clean terminals and maintain charge for reliable automatic starts.
• Check fuel system and lines for leaks or damage, especially on LP/NG installations.
• Keep vents and cabinet clean to avoid overheating and corrosion in outdoor environments.
• Use the Kohler Energy Management App for real‑time alerts, diagnostics, exercise scheduling, and maintenance reminders.
• Verify controller settings & firmware occasionally to ensure connectivity and accurate monitoring (especially remote features).
