Use the parking brake control to engage or disengage the parking brake when you park the machine. The parking brake control is a push-pull type switch.
Parking Brake Control - Pull parking brake control knob outward to the OFF position in order to disengage the parking brake. Push the parking brake control knob inward to the ON position in order to engage the parking brake. Parking Brake Drive Through
In the case of a hydraulic failure where pressure oil to release the parking brake is not available, a drive through mode is provided. Allowing the machine to be driven through the parking brakes to a safe location.If a hydraulic or electrical failure occurs, the parking brake may automatically engage. Perform the following procedure to move the machine under these conditions. During this procedure, the monitoring system activates a category 2-S warning.
Make sure that the area is clear of personnel and other machines.

Wheel steering machines - typical example
Move transmission direction and speed control (1) to the FIRST speed forward or FIRST speed reverse position.
In a rapid motion, move transmission direction control (1) to the NEUTRAL position and then back to FIRST speed forward or FIRST speed reverse position.
Increase the engine speed and the machine will drive through the engaged parking brake.
Steer the machine to a safe location.
Driving the machine through the parking brakes for an extended period can cause severe damage to the braking system.Inspect the parking brake system and make any necessary repairs before returning the machine to operation.
Service Brake
Illustration 6 g00897634
Service Brake/Transmission Neutralizer Pedal (1) - Use the left brake pedal to disengage the transmission and to slow down the machines ground speed. Permitting higher engine speed for better hydraulic response.
APPLY - Depress the left brake pedal when truck loading, positioning or when raising the bucket to increase hydraulic speed and reduce unnecessary torque converter stalling. The left brake pedal can also be used to give additional hydraulic power in difficult or tight digging conditions.
RELEASE - Release the pedal to re-engage the transmission and to release the brake. Service Brake Pedal (2) - The right brake pedal slows down the machine ground speed for normal braking.
APPLY - Depress the right brake pedal for normal machine braking.
RELEASE - Release the right pedal in order to release the brake. If the service brake pedal does not stop the machine, use the parking brake control to stop the machine. When the machine stops, block the wheels. If necessary, make repairs.Secondary Brake
Personal injury or death can result from a brake system malfunction.If the secondary brake is required in order to stop the machine, the machine stopping distance will be increased.Personal injury could result from the sudden stop of the machine. Be prepared for a sudden
