For vehicles with single-wheel suspension:
Place the wheels on swivel plates.
Rotate the steering wheel, with and without hydraulic assistance, to the maximum lock stop.
This will cause the piston to push the sliding bush on the screw (20 and 128) up to the
required cut-off position (Fig. 15) .
Note:
During this setting operation the steering limiter valve is constantly open which means that, with
as well as without hydraulic assistance, the steering wheel can only be rotated further at an in-
creased effort.
Repeat the setting operation for the other direction of rotation.
