Throttle valve, levelling unit
The retraction speed of the hydraulic cyl-
inders on both chassis legs can be ad-
justed by their respective throttle valves.
These two throttle valves are located be-
hind the left-hand flap on the engine
compartment.
- Left-hand throttle valve (1): Left-hand
chassis leg
- Right-hand throttle valve (2): Right-
hand chassis leg
Adjust deployment speed:
- Rotate adjusting knob clockwise = slower retraction speed.
- Rotate counter-clockwise = faster retraction speed.
With optional levelling equipment, the setting values need to be adapted after adjust-
ment!
Load relief of moldboard
For certain defined working situations, the load relief on the moldboard can be adjust-
ed.
The handwheel (3) used for pressure setting is located on the valve block behind the
left-hand flap on the engine compartment.
The current pressure setting can be read off from the pressure gauge (4).
Adjust load relief setting:
- Unfasten lock nut using plastic wheel (5).
- Use handwheel (3) to set the desired pressure:
- Turn adjusting knob clockwise = less pressure
- Turn adjusting knob counter-clockwise = higher pressure
- After setting pressure, continue tightening the lock nut using the plastic wheel (5).
The adjustment range is 0...210 bar
