Throttle Lock Control - The throttle lock switch is located on the left side of the instrument panel. Engage the switch in order to keep the engine at the current rpm. When the throttle lock is active, an indicator light will illuminate on the front dash. Use the throttle lock control on long hauls in order to avoid driver fatigue. Fatigue may result from depressing the throttle control for an extended period of time. On - Push the top of the switch in order to engage the throttle lock control.Off - To release the throttle lock control, push the bottom of the switch or slightly depress the right brake pedal.Setting the Throttle Lock
The throttle lock can be set for a desired rpm.
Push the throttle lock control to the ON position.
The indicator light for the throttle lock will illuminate when the on/off switch is in the ON position.
Depress the throttle control in order to achieve the desired engine rpm.
Depress the "Set/Decel" switch that is located on the control console on the right side of the seat in order to set the throttle. Cancelling the Throttle Setting
The throttle setting may be cancelled by depressing the right brake pedal or by moving the on/off switch to the OFF position.When the right brake pedal is used to cancel a throttle setting, press the "Resume/Accel" switch that is located on the control console on the right side of the seat in order to resume the throttle setting.Accelerate or Decelerate
In order to accelerate to a higher rpm, continue pressing the Resume/Accel switch. Once the switch is released the previous setting will resume.In order to decelerate to a lower rpm, continue pressing the Set/Decel switch. Once the switch is released the previous setting will resume.Left Brake Pedal and Impeller Clutch (6)
The left brake pedal controls both the brake pressure and the impeller clutch pressure.Partially depress the left brake pedal in order to reduce the impeller clutch pressure. The brake pressure is increased as the operator pushes down the pedal farther. This feature allows the operator to control the maximum drive train torque. Lowering the maximum drive train torque supplies more engine power to the implements and to the steering.When the operator is digging, the left brake pedal can be used to stop any excessive tire slip.Engine Brake Control (7)
The engine brake control is operated by using a pedal that is located in the cab of the operator's compartment. The engine brake control aids in preventing excessive wear on the service brakes by decreasing the speed of the engine.The engine brake control should be used before applying the right service brake pedal. The engine brake control should not be used with the left brake pedal.Apply the engine brake control when the machine is travelling downhill. The transmission can be downshifted while you are using the engine brake control. The right service brake pedal can also be applied, if necessary.Note: The torque converter lockup switch should be in the ON position in order to use the engine
