AH82.30-P-0001-01A Notes On Wiper Arm Adjustment
By checking the angle of incidence of the wiper arms in parked position and reverse position it can be assessed whether the wiper arm or the wiper system is to be adjusted.
^ Adjusting wiper arm
In the event that the test values deviate from the tolerance range in reverse position or in parked position and reverse position:
The angles of incidence are changed by "twisting" the wiper arms with the aid of the adjuster levers. The angle of incidence of the wiper arm always has to be adjusted in parked position.
In doing so the angle of incidence in parked position and reversing position changes by the same amount. The angle of incidence of the wiper arm to be adjusted is changed by at least the value of the tolerance deviation in reversing position. To make sure that both adjustment values lie within the tolerance range, the angle of incidence has to be checked again in parked position and corrected if necessary.
^ Adjusting wiper system
In the event that the test values of both wiper arms deviate from the tolerance range in parked position.
