Left Brake Pedal and Impeller Clutch (2)
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 work tools and to the steering.
When the operator is digging, the left brake pedal can be used to stop any excessive tire slip.
Note: The left brake pedal must be released to allow the lockup clutch to engage (if enabled).
Note: The left brake pedal will not disengage throttle lock if the throttle lock is engaged.
Note: Calibration of the left brake pedal is necessary in order to compensate for normal mechanical wear.
Reference: Refer to Testing and Adjusting, KENR5566 for information about calibrating the left brake pedal.
Engine Brake Control (3) (If Equipped)
The engine brake control feature (if equipped) provides both manual and automatic machine engine braking. 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 traveling 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: When activated, the engine brake control will disable throttle lock.
The engine brake control is operated by using pedal (3) that is located on the floor in the operator cab.
The following conditions must exist for the manual engine brake control to operate:
- The transmission must be in a gear in which the lockup clutch is available and engaged.
- The transmission input speed must be above 1500 rpm.
- The operator must not be using the left brake pedal.
- The operator must not be using the throttle control.
The manual engine brake control will remain active until one of the following events occurs:
- The engine brake control pedal is released by the operator.
- The transmission input speed falls below 1400 rpm.
Automatic Engine Brake Control
Automatic engine brake control is integrated into the machine electronic control modules (ECMs) and is enable through ET. This feature works in all gears except first forward.
The following conditions must exist for the automatic engine brake control to operate:
- The transmission must be in a gear in which the lockup clutch is available and engaged.
- The transmission input speed must be above 2000 rpm.
- The operator must not be using the left brake pedal.
- The operator must not be using the throttle control.
Once automatic engine brake control is activated, this feature will remain active until the transmission input speed falls below 1750 rpm.
Note: Automatic engine brake control will be deactivated when transmission input speeds rise above 2200 rpm. This strategy is used in order to disengage the lockup clutch at these speeds. The result of disengaging the lockup clutch is to prevent overspeeding the engine.
