Safety first: Disconnect power before performing maintenance.

• Perform scheduled maintenance: Clean or replace solution and vacuum filters, inspect brushes for wear, check hoses and seals, and verify all safety devices function correctly.
• Inspect carbon brushes (if applicable): On some Nilfisk motors, carbon brushes must be checked and replaced at set intervals. Replace with genuine Nilfisk brush kits if worn.
• Reset service indicator: Follow the user or service manual procedure to reset the service timer (often involves holding specific buttons at power‑on). Only reset after completing maintenance.
• Record service: Log the date, hours, and work performed for future reference.
