Operation 5
Releasing the pressure in the work hydraulics
1. Stop the machine on firm, level, and horizontal ground.
2. Lower the attachment completely to the ground.
3. Lower the stabilizer blade to the ground.
4. Stop the engine.
5. Turn the starting key to position
1 .
6. Move the control lever or the slide switch of the proportional controls of
the relevant hydraulic circuit in all directions repeatedly.
➥
The pressure in the corresponding system sections is released.
This can be seen by the brief movement the hoses make as the
pressure is released.
➥
Uncouple the attachment immediately after the pressure has been
released, otherwise pressure can be created again.
Re-equipping
Removing

Place the bucket only with minimum pressure on the ground as you
remove the pins. The higher the pressure on the ground, the higher the
resistance and the more difficult it is to remove the pins.
