Checking the condition and replacing the windshield wiper blades
1. The windshield wiper mechanism with replaceable blades should be periodically checked for damage, loose connections and wear of the blades.
2. During use, a "road film" forms on the brushes, which impairs their performance, so the brushes should be regularly washed in a solution of mild detergent.
3. The windshield wiper threads may become loose over time. They need to be checked and tightened, if necessary, at the same time as checking the condition of the brushes.
4. If the wiper blades are cracked, heavily worn or deformed, and as a result the windshield is not cleaned well, they must be replaced.
5. Remove the blade from the wiper arm by pressing the locking lever and pulling the assembly down, while simultaneously releasing it from the hook at the end of the arm (see Figure 6.5).
