        Checking and Adjusting of the Hydraulic System  (see figure below) 
 
 
1. Start the machine in automatic running mode and wait for approximately 20 
minutes.                                              
2. When the ram moves forward the pressure gauge (1) should indicate 0 – 30 bars 
depends on the adjustment of the throttle check valves (2).  (Also adjust the 
speed of the ram with this valve.) 
3. When the ram moves backwards the pressure gauge (1) should indicate 0 – 30 
bars depends on the adjustment of the throttle check valves (2). 
4. The pressure gauge (1) should indicate 50 – 70 bar at the change over point of the 
hydraulic cylinders other wise the spill over hand wheel (3) should be adjusted. 
5. The pressure gauge (4) should indicate a maximum of 2.5 MPa other wise the 
screw of the sequence valve (5) has to be adjusted. 
6. The ram should run upwards in less than 10 seconds, otherwise the throttle check 
valve (2) has to be adjusted. 
7. When pressure gauge at the oil filter (6) indicates >5 bar, the filter should be 
replaced.
