The pressure for hydraulic suspension may need adjustment. It can al-
so be necessary to adjust pressure according to soil conditions. 

 

Excessive pressure 

1

 

If the cylinder does not move, pressure is too great. This can cause ex-
cessive strain on the frames.  
 

2

 

Reduce pressure until the cylinder moves again.  
 

Insufficient pressure 

1    Pressure is too low if the cylinder cannot extend fully.  
 
2

 

Adjust 

(increase) 

pressure until all 5 suspension cylinders extend.  

 

 

 
We recommend running at a pressure of 70 bar!  
But always operate according to conditions!
