Controller displays “Service Required” or “Maintenance Reminder”; generator still operates normally.

Safety first: Turn generator OFF and open main breaker before performing maintenance.

• Perform maintenance: Follow the Kohler maintenance schedule: change engine oil and filter, replace air filter and spark plugs (if due), inspect belts and hoses, and check battery and connections.
• Inspect enclosure: Clean debris from inside the enclosure, verify louvers are clear, and check for rodent damage.
• Reset reminder: Use the controller menu (RDC2/DC2) to reset the maintenance interval after completing service, per the owner’s manual.

Ignoring service reminders can lead to reduced reliability and shortened engine life.
