6.Move the remote control valve lever No. 1 between ‘Extend’ and ‘Neutral’ position. The charge pressure readings should not vary outside 2.1 – 2.9 bar ( 30 – 42 lbf/in2).

If the pressure reading is below 2.1 bar ( 30 lbf/in2), replace the hydraulic oil filters and re-test.

If after re-test charge pressure is still below specification examine both the charge pressure filter dump valve and charge pressure valve before disassembling pump to inspect for wear.
