4. Setup and Installation
This section details the procedure for installing the brush onto a compatible Clarke Encore floor scrubber.
- Prepare the Scrubber: Ensure the floor scrubber is powered off and unplugged from its power source. Raise the brush deck to access the brush mounting area.

- Align the Brush: Position the Clarke 51447D brush beneath the scrubber's brush deck. Align the clutch plate of the brush with the drive hub on the scrubber. The brush features a dual-direction design, so specific orientation is not required for functionality, but ensure it seats properly.
- Secure the Brush: Gently push the brush upwards until the clutch plate engages with the drive hub. You may need to rotate the brush slightly to ensure proper engagement. The brush should fit snugly and securely.
- Verify Installation: Once installed, gently pull down on the brush to confirm it is securely attached and does not wobble. Lower the brush deck.

6. Maintenance
Regular maintenance extends the life of your brush and ensures consistent cleaning performance.
- After Each Use: Remove the brush from the scrubber. Rinse the bristles thoroughly with clean water to remove dirt, debris, and cleaning solution residue.
- Inspection: Periodically inspect the bristles for wear, damage, or excessive matting. Check the clutch plate for any signs of damage or wear.
- Storage: Store the brush in a clean, dry area, preferably hanging or on its side to allow bristles to dry completely and maintain their shape. Avoid storing in direct sunlight or extreme temperatures.
- Replacement: Replace the brush when bristles show significant wear, are severely matted, or if the clutch plate is damaged, as this can affect cleaning effectiveness and potentially damage the scrubber.
