Do not turn the adjusting screw of the hydraulic valve while operating a hydraulic
control, as this may permanently damage the valve.
1. For each of the three valves:
a. Slightly loosen the locknut on each valve and screw the adjusting screw two turns
to increase the pressure.
b. Re-test the hydraulic pressure as described in step 3 above and check that it reads
above 3,970 psi. If you cannot reach 3,970 psi by adjusting the valves, the pump
pressure is not high enough. In that case, you need to increase the pump pressure
to 3,970 psi before proceeding with adjusting the valves. To do so, screw the
adjusting screw on the pump to increase the pressure.
