Wiper adjustment method:
1, preparation tools: a screwdriver and two adjustable wrench (one for fixing and one for adjusting, or pliers can be used instead);
2. Pull the wiper up a certain distance along the angle of the glass, and then lift the wiper arm outward. (Note: Some models will damage the wiper arm if lifted directly. Different models enter the maintenance mode in different ways, which needs specific analysis);
3. Remove the wiper strip to prevent accidental injury during maintenance. Put a towel on the wiper arm to prevent the paint from rubbing off during the adjustment;
4. Hold the elbow with one wrench and twist it gently in different directions with the other wrench. Adjust the elbow top counterclockwise when lifting upward and jumping; If you jump when scraping, twist it clockwise. Pay attention, otherwise it will damage or even break the wiper arm;
As a matter of fact, the abnormal sound, jumping and incomplete scraping of the wiper may not only be caused by the bending of the wiper arm. It may also be that the wiper blade is aging, glass grease accumulates, or other protective equipment is applied. Blind adjustment will not only damage the wiper itself, but also damage the windshield if it is not adjusted well, so it is not recommended to do it yourself.
