If the above operation does not recover the wiper operation, it may be that the surface of the wiper is dry, and the motion of the exercise is caused to take the champion on the right side of the reversing the valve body, screwed into the right end with bolts. In the threaded hole, pull out the piston, lubricate, can exclude the fault.
