6. Maintenance

To ensure the longevity and effective performance of your lower duct repair hose, consider the following maintenance tips:

• Regular Inspection: Periodically inspect the hose for any signs of wear, tears, or punctures.
• Clear Obstructions: If suction decreases, check the hose for any blockages or debris and remove them carefully.
• Avoid Kinks: While the hose is flexible, avoid extreme bending or sharp angles that could lead to permanent kinks or damage.
• Cleaning: Wipe the exterior of the hose with a damp cloth as needed. Avoid using harsh chemicals.

7. Troubleshooting

If you encounter issues after installing the new hose, consider these troubleshooting steps:

• Reduced Suction: Ensure the hose is fully screwed in and all connections are airtight. Check for any internal blockages that might have occurred during reassembly.
• Hose Disconnection: Verify that the hose is securely attached to both ends within the vacuum head. Re-tighten if necessary.
• Kinks: If the hose develops a kink, gently straighten it. Repeated kinking can lead to damage and reduced airflow.
