Ride Control
"Ride Control" (5) - Travel over rough terrain causes bucket movement and a swinging motion. When activated, the ride control function acts as a shock absorber by dampening the forces that are caused by the movement of the bucket. This system will also stabilize the entire machine. When the soft switch panel button is pressed, the Machine ECM will activate the ride control system and will illuminate the LED indicator. When the soft switch panel button is pressed again, the Machine ECM will deactivate the ride control system and turn OFF the LED indicator.Parking Brake Control Switch
Note: If the brake system oil pressure drops below normal operating pressure, a warning horn will sound, the brake accumulator error indicator will come on, the action light will come on, and the parking brake will engage automatically.Note: Do not engage the parking brake while the machine is moving unless the wheel brakes fail. The use of the parking brake as a wheel brake in regular operation can result in severe damage to the parking brake system.
Parking Brake Control (6) - To engage the parking brake, press the parking brake switch. When the parking brake is in the engaged position, the LED above the switch will illuminate and the parking brake indicator on the Monitor illuminates.Note: When the left console is in the RAISED position, the parking brake will be engaged.Note: The parking brake will not engage when low transmission clutch pressure is detected. However, the travel activation will be deactivated and the parking brake solenoid will not change states.Refer to Systems Operation, "Parking Brake Function" for more information on this function.The parking brake on the machine is engaged with the use of a spring force that locks the transmission in place to prevent movement. When one of the transmission gear shift solenoids is energized, the hydraulic force counters the force of the springs to disengage the parking brake.When the machine ECM determines that the parking brake must be engaged, the ECM will de-energize both of the transmission solenoids. De-energizing the solenoids allows the spring to engage the parking brake.The ECM sends a signal to the soft switch panel (soft switch panel) to illuminate the led indicator above the parking brake button.The ECM controls the parking brake under the following conditions.
Left armrest is moved to the raised position, the ECM engages the parking brake. the ECM will disengage the parking brake when the armrest is moved to the down position if no engage command has been received from the soft switch panel button.
Backup mode is active, the ECM will disengage the parking brake.
Parking brake is engaged and the brake system pressure sensor indicates that the service brake pedal is depressed, the ECM will disengage the parking brake when the brake system pressure sensor indicates that the service brake pedal is released.
Parking brake is engaged and the parking brake switch on the soft switch panel is pressed, the ECM will energize the selected gear solenoid to disengage the parking brake.If there is
