Use the left brake pedal or the right brake pedal to slow down the machine's ground speed. The machine will slow down more as the pedal is depressed farther.
The left brake pedal also controls the transmission neutralizer if the function is activated.
Reference: For more information, refer to Operation and Maintenance Manual, "Transmission Neutralizer Override Control".
Engage - Depress either brake pedal in order to slow down the machine. Fully depressing either brake pedal will stop the machine completely.
Disengage - Release the brake pedal in order to accelerate from a slower speed. If the machine is completely stopped, releasing the brake pedal will allow machine movement to resume.
Machines with Integrated Braking System (IBS)

| Illustration 14 | g00884100 |
Use the right brake pedal in order to slow down the machine's ground speed for normal braking. The right brake pedal will only function as a conventional brake pedal.
The right service brake pedal should be used when the operator does not wish to have the transmission downshift aggressively. The right pedal is normally used when standard downshifting is adequate. This is based on the rpm of the engine and the ground speed of the machine. The transmission will remain in the current gear if the autoshift switch is in the MANUAL position. The transmission will downshift if the autoshift switch is in the AUTOMATIC position.
The left brake pedal can be used as a conventional brake pedal as well as a downshift switch for the transmission in order to slow the machine. The left brake pedal can be used in order to downshift the transmission when the machine is travelling downhill regardless of the position of the autoshift switch. This will save wear on the service brakes.
The left brake pedal is recommended for most conditions when adequate traction is available.
The left brake pedal controls the downshifting of the transmission, the neutralizing of the transmission, and the application of the service brakes. These functions depend on the position of the left brake pedal.
During the initial travel of the left brake pedal, the transmission will be downshifted. Each downshift of the transmission will reduce the speed of the machine. The transmission will be downshifted at higher travel speeds. The transmission will only downshift if an engine overspeed will not occur. The transmission will only shift between the speeds that are selected with the autoshift switch.
The transmission will also be neutralized when the left service brake is depressed further and the machine speed has been reduced to a preset speed. The service brakes are then applied.
The transmission will be engaged again after the left brake pedal is released two degrees from the maximum pedal position. This will only happen if the transmission was neutralized. The service brakes will still be applied. This will allow the transmission to be engaged when the brakes are applied. This will help to prevent unwanted movement while you are on a slope.
Note: You should wait for at least one second after releasing the left brake pedal for two degrees before completely releasing the pedal. This will allow the transmission to fully engage.
Fully depressing the left pedal will neutralize the transmission again.
When the left pedal is released, the transmission will return to normal operation. The transmission will upshift to the previously selected gear speed.
Steering Column Tilt Control (8)
To adjust the steering column, pull up on steering column tilt lever (8) and move the steering column to the desired position. Release lever (8) in order to lock the steering column in the desired position.
Steering Wheel Telescopic Control (9)
This control is available on machines which are equipped with command control steering.
Rotate lever (9) counterclockwise in order to move the steering wheel to the desired height. Rotate lever (9) clockwise in order to lock the steering wheel in the desired position.

- “Operator Controls (Electro-Hydraulic Work Tool Controls)”
Increasing the Speed - Depress pedal (11) in order to increase the engine speed. If the brakes are not engaged, the machine's ground speed will also increase.
Decreasing the Speed - Release pedal (11) in order to decrease the engine speed. If the brakes are not engaged, the machine's ground speed will also decrease.
