Venting the Steering Hydraulics

If the steering cylinder hydraulics have been dismantled, it is necessary
to vent the cylinders. Depending on the sprayer size, the venting screws
(A) are installed as shown on the pictures.
1. Remove the dust cap from the venting screw (A) on the left side
steering cylinder.
2. Mount a clear 5 mm hose to the venting screw and lead it into a
catch can.
3. Open the venting screw 1/8 turn and then steer fully to left (retract
cylinder).
4. Hold the steering position, until air is no longer visible in the hose.
5. Close the venting screw (A) again.
6. Repeat the procedure for the right side cylinder.
7. Steer fully from left to right 8-10 times.
8. Complete the venting procedure again to ensure that there is no
air in the system.
9. Mount the dust caps onto the venting screws again.
