Wear Bushing Renewal on Steering
If too much play is found in the steering, the wear bushes must be replaced. This should be done at your local HARDI dealer.
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.

DANGER! Be careful when operating the steering! Make sure that there is space enough to steer the sprayer from side
to side! Only persons working on the sprayer is allowed in the moving area of the sprayer!
Suspension Rubber Dampers (optional)
If the shock absorbers loose their efficiency, they should be replaced.
1.
Connect the sprayer to a tractor to prevent overbalancing.

Lift the rear end of the sprayer with e.g. a crane. Use lifting points as described in “Sprayer setup”.
3.
Loosen the nut below the suspension rubber dampers.
4.
Remove the suspension rubber dampers and replace with new ones.
5.
Tighten the nut below the suspension rubber dampers.

Lower the rear of the sprayer again.
