When checking the angle of incidence of the wiper arm in the park and center position, it is determined whether the wiper arm or windshield wiper system must be adjusted.

Adjusting wiper arm 

If the test value deviates from the tolerance range in the center position.

Change in the angle of incidence is achieved by "twisting" (folding) the wiper arm by means of the adjustment lever. The angle of incidence for the wiper arm relative to the windshield must always be adjusted in the center position.

When in the center position, the wiper arm must be positioned exactly parallel to the windshield. Correct offset of the wiper arm in the center position is necessary for low-wear and low-noise wiper blade movement on the windshield.

Adjust windshield wiper system 

Only if the test value deviates from the tolerance range in the park position.

By checking the angle of incidence of the wiper arms in parked position and reversing position, it can be assessed whether one wiper arm, both wiper arms or the wiper system are to be adjusted.

The wiper arms are adjusted in case the check values deviate from the tolerance range in reversing position or in case the check values deviate from the tolerance range in reversing position and parked position.

The angle of incidence is changed by twisting (crossing over) the wiper arms with the aid of the adjustment lever. 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 altered by at least the tolerance deviation value in the reversing position. In order to ensure that both set values lie within the tolerance range, the angle of incidence must be checked in the parked position again and corrected if necessary.

If there is any deviation in the check values for both wiper arms from the tolerance range the windshield wiper system is set to the parked position.
