Over center valve in          70 bar or 840 psi
Over center valve out       75-80 bar or 1050-1120 psi

1. Free wheel the winch.
2. Push the lever so the cable is winding out, (drum will not turn as it is in free-
    wheel position.)
3. The gauge should read approx. 75-80 bars.
     to increase the pressure -turn adjustment screw A to the left.
     to reduce the pressure -turn the adjustment screw A to the right.
 
4. Pull lever so the cable is winding in. The gauge should read 70 bar
    Turn adjustment screw B to set correct pressure.

5. When done with A&B settings engage the winch again for test.

6. Pull winch lever so the winch cable starts to pull. Now turn valve C until the
    winch speed is changing. Turn the sequence valves set screw C to 85 bar.
    Than turn the screw further 3/4 to 1 turn to the right and lock the adjustment.
    Your winch should now work without problems.
