Before you install the new blade, remove the old blade from the wiper’s arm, remove the adapter (or use the original one) and mount the wiper with this adapter to the arm. Mount the wiper with the spoiler always in the place in front of the driver. Warning: After installation check the mounting of the blade on the arm in order to avoid its slipping and, in consequence, to prevent any damage to the windscreen. The length of the wiper’s blade must be at least the same as the length of the original one. We recommend replacing the blades every 6 months to ensure safe driving and proper view for the driver.
