For detailed, vehicle-specific installation instructions, refer to your vehicle's owner's manual or search for specific guides online using your vehicle model and the Bosch Aerotwin wiper blade model.
6. Operating Instructions
Once installed, the Bosch APX16 Aerotwin windscreen wiper operates like any standard wiper blade. Activate your vehicle's wiper system as needed for clear visibility during rain, snow, or when cleaning the windscreen.
- Use windscreen washer fluid for optimal cleaning, especially when the windscreen is dry or dusty.
- Avoid operating wipers on a completely dry windscreen for extended periods, as this can damage the blade and scratch the glass.
7. Maintenance
Regular maintenance helps prolong the life and effectiveness of your wiper blades.
- Clean Blades Regularly: Wipe the rubber edge of the wiper blades with a soft cloth dampened with windscreen washer fluid or mild soapy water. This removes dirt, grime, and road film that can cause streaking.
- Inspect for Damage: Periodically check the rubber blade for cracks, tears, or hardening. Damaged blades should be replaced immediately.
- Clear Debris: Remove any leaves, ice, or snow from the windscreen and wiper blades before operation.
- Avoid Harsh Chemicals: Do not use petroleum-based cleaners or solvents on the wiper blades, as these can degrade the rubber.
8. Troubleshooting
If you experience issues with your wiper blades, consider the following common problems and solutions:
- Streaking or Smearing:
- Clean the wiper blade rubber thoroughly.
- Check for wax or oil residue on the windscreen and clean it with a glass cleaner.
- Inspect the blade for damage; replace if necessary.
- Chattering or Skipping:
- Ensure the wiper arm is not bent and applies even pressure across the blade.
- Clean the blade and windscreen.
- The blade might be old or hardened; consider replacement.
- Incomplete Wipe Area:
- Check if the wiper arm is bent or if the blade is incorrectly installed.
- Ensure the correct blade length is used for your vehicle.
If problems persist after troubleshooting, it may be time to replace your wiper blades or consult a professional.
