The components for the QuickEvac mode consist of the pump and motor (secondary steering, brake release, prelubrication, and high speed oil change - QuickEvac) (1), the secondary steering pressure switch (2), the Engine Lockout lamp (3), the toggle switch (Engine Lockout) (5), and the 187-1458 High Speed Oil Change Tool Gp (not shown). The components are monitored and controlled by the Transmission/Chassis ECM in order to perform the QuickEvac mode.
Pump and Motor (secondary steering, brake release, prelubrication, and high speed oil change - QuickEvac) (1) is located on the frame under the engine.
Note: Pump and Motor (secondary steering, brake release, prelubrication, and high speed oil change - QuickEvac) (1) is the same pump that is used for the prelubrication oil pump.
Note: Machine lockout switch (6) does not affect the QuickEvac system. Machine Lockout lamp (4) does not affect the QuickEvac system. While machine lockout switch (6) leaves the engine start enabled, machine lockout switch (6) disables the movement of the machine.
The activation of the engine lockout function is indicated when Engine Lockout lamp (3) is ON. After the engine lockout function is in the ON mode, theQuickEvac hydraulic connections and electrical connections need to be connected in order to perform the QuickEvac mode. When the 187-1458 High Speed Oil Change Tool Gp is installed onto the machine, a ground signal is sent to the Transmission/Chassis ECM. This signal indicates that the service hose and the electrical connection is installed. The pump and motor (secondary steering, brake release, prelubrication, and high speed oil change - QuickEvac) (1) can be turned ON by depressing a remote switch on the service hose, which will begin evacuating oil from the machine. An event is logged by the Transmission/Chassis ECM when a QuickEvac is performed.
The Transmission/Chassis ECM is used to monitor secondary steering pressure switch (2) during a high speed oil change in order to ensure that the front wheels of the machine are not attempting to be turned via the steering wheel. If this occurs, secondary steering pressure switch (2) will send an OPEN circuit to the Transmission/Chassis ECM. The Transmission/Chassis ECM will turn off pump and motor (secondary steering, brake release, prelubrication, and high speed oil change - QuickEvac) (1) and Engine Lockout lamp (3) will flash. In order to resume QuickEvac mode, the toggle switch (Engine Lockout) (5) needs to be turned to the OFF position while the key is in the OFF position and the engine lockout function is successfully engaged.
Note: Make sure that the electrical connections and the hydraulic connections are properly connected when a service hose is installed.
Note: Engine Lockout lamp (3) will flash, if the Transmission/Chassis ECM indicates that a service hose and the electrical connection is attached and that the engine is OFF but the engine lockout function is not engaged. This will inhibit the secondary steering and prelubrication functions. Starting the engine will also be inhibited.
Note: Engine Lockout lamp (3) will flash, if the engine is running and a service hose and an electrical connection is attached. Also, the secondary steering will be inhibited if the ground speed is equal to 0 mph.
