1) Cleaning
If paste or other sticky substances get on the windshield or the blades, the wiper's performance deteriorates and the blades begin to rattle. To restore normal operation, it is necessary to clean the glass and the blades.
Wash the windshield with a mild soap solution or windshield washer fluid. The glass is considered clean if no drops form when you pour clean water on it.
The brushes are cleaned with a cloth soaked in windshield wiper fluid or a mild soap solution and finally doused with clean water. If after this the windshield wiper operation does not return to normal, then the brushes must be replaced.
2) Replacing brushes
1. Pull back the windshield wiper handle.
2. Press the locking pin and remove the brush.
3. Insert the new brush into the handle until it snaps into place.
ATTENTION!
- After replacing the brushes, return the windshield wiper arms to their original position. Otherwise, they may break when opening the hood.
- Make sure the brush fits snugly on the glass, otherwise the handle may break from the wind pressure.

When lubricating the hood with protective paste, make sure that the paste does not get into the windshield wiper nozzle. This can lead to clogging of the nozzle and deterioration of the windshield wiper operation. If paste gets into the nozzle, remove it with a needle or pin.
