If the above operation does not restore the wiper operation, it may be that the surface of the wiper is dry, and the motion of the movement is to pick up the champion on the right side of the rotating valve body, screwing into the right side. Bolt. In the threaded hole, pull out the piston, lubricate, and can eliminate the fault.
When the wiper has a significant leak, the cause is damaged when the cause is damaged and need to be replaced.
