Hydraulic Lockout Lever (LOCKED Position)
(3) Hydraulic lockout lever
(4) Lever
(5) Plunger
(6) Limit switch When hydraulic lockout lever (3) is shifted to the LOCKED position, no signal is sent to the machine ECM. The machine ECM will not send an electrical signal to solenoid valve (1). Pilot oil is not supplied to the main control valve, travel control valve and swing brake solenoid. The implements are inoperable when the hydraulic lockout lever is in the LOCKED position.When hydraulic lockout lever (3) is shifted to the UNLOCKED position, lever (3) contacts plunger (5). Plunger (5) causes the electrical circuit of limit switch (6) to be CLOSED. Limit switch (6) sends a signal to the machine ECM. The machine ECM sends an electrical signal to solenoid valve (1). The electrical signal energizes solenoid valve (1). Pilot oil from solenoid valve (1) shifts hydraulic activation valve (7). Pilot oil flows through hydraulic activation valve (7). Pilot oil flows to the main control valve, travel control valve and swing brake solenoid. The implements are operable when the hydraulic lockout lever is in the UNLOCKED position.Note: The engine does not start unless hydraulic lockout lever (3) is in the LOCKED position. Ensure that the hydraulic lockout lever is in the LOCKED position when starting the machine.Solenoid Valve (Locked Position)

(17) Passage
(18) Passage (oil flow to hydraulic tank) The solenoid valve (hydraulic lockout) (1) consists of solenoid (8), spring (9), and spool (10).When hydraulic lockout lever (3) is in the LOCKED position, plunger (5) is not in contact with hydraulic lockout lever (3). Switch (6) does not complete the circuit that energizes solenoid (8). Solenoid (8) is not energized. Spool (10) is forced upward by spring (9). Pilot oil is not able to flow from passage (15) to passage (17).Solenoid Valve (Unlocked Position)

(18) Passage (oil flow to hydraulic tank) When hydraulic lockout lever (3) is in the UNLOCKED position, plunger (5) is in contact with hydraulic lockout lever (3). Switch (6) is CLOSED which completes the circuit that energizes solenoid (8). Solenoid (8) is energized causing spool (10) to shift downward against spring (9). Pilot oil flows from passage (15) to passage (17).Hydraulic Activation Valve
