Installation Guide

1. Remove the Existing Blade: Detach the old wiper by releasing the mounting clip or screw on the arm. Carefully lift the blade away to avoid damaging the rubber seal.
2. Align the New Blade: Position the Bosch 3397018191 so that the under‑hook fits snugly onto the wiper arm’s attachment point. Ensure the silicone edge is centered over the windshield.
3. Secure the Mounting Hook: Press the hook into place until it clicks, confirming a firm connection. Verify that the blade does not shift when gently moved.
4. Test Operation: Activate the wiper system to confirm smooth motion across the entire windshield. Adjust if necessary to eliminate any gaps or uneven contact.

Performance Benefits

• Consistent Visibility: The twin silicone layers maintain a firm yet flexible seal, providing reliable wiping even in high‑speed or turbulent conditions.
• Extended Durability: Designed to endure the rigors of commercial use, the blade resists cracking and wear that typically affect standard passenger vehicle wipers.
