4. Setup and Installation
Follow these steps to properly install the Tennant 374042 brush onto your compatible floor scrubber:
- Prepare the Scrubber: Park the floor scrubber on a level surface. Turn off the machine and remove the key. Disconnect the battery or unplug the power cord to prevent accidental startup.
- Access the Brush Deck: Depending on your specific scrubber model, you may need to raise the brush deck or tilt the machine to access the brush compartment. Refer to your scrubber's manual for exact instructions.
- Remove Old Brush (if applicable): If replacing an existing brush, disengage it from the drive mechanism. This usually involves a quick-release lever or a simple twist-and-pull motion.
- Install New Brush: Align the Tennant 374042 brush with the drive hub in the brush compartment. Push or twist the brush until it securely locks into place. Ensure it is fully seated and cannot be easily dislodged.
- Verify Installation: Gently tug on the brush to confirm it is firmly attached. Lower the brush deck (if raised) and reconnect the power source.

- Select the appropriate cleaning solution for your floor type and soil level.
- Adjust brush pressure settings on your scrubber as recommended for optimal cleaning performance without excessive wear on the brush or floor.
- Regularly check the brush during operation for any signs of entanglement or unusual wear.
6. Maintenance
Proper maintenance extends the life of your Tennant 374042 brush and ensures consistent cleaning performance.
- Daily Cleaning: After each use, remove the brush from the scrubber. Rinse the brush thoroughly with clean water to remove dirt, debris, and cleaning solution residue.
- Inspect for Wear: Regularly inspect the bristles for signs of excessive wear, matting, or damage. Replace the brush if bristles are significantly worn down or damaged, as this can reduce cleaning effectiveness.
- Storage: Store the brush in a clean, dry area, preferably hanging or standing on its end to allow bristles to dry completely and maintain their shape. Avoid storing it flat on its bristles.
- Chemical Exposure: Avoid prolonged exposure to harsh chemicals that may degrade the polypropylene bristles.
