1) Manually shift the directional control valves of the hydraulic
circuit under service.
2) Open the hose fittings 1/8 to 1/4 of a turn (CCW) at the
cylinder or motor of the hydraulic circuit under service. This
allows the pressurized oil to bleed off. Service or perform
maintenance on the hydraulic circuit after the steady flow is
gone.
NOTE
This allows pressurized hydraulic oil between a directional
control valve and the cylinder/motor to bleed off that might still
be in that circuit.
