Illustration 1 g02134072Service brake control (pedal) (1) is located to the left of accelerator control (2).Use the service brakes for stopping the machine and use the service brakes in order to avoid an engine overspeed.Engage - Press the pedal in order to engage the service brakes. Use the service brakes for reducing ground speed or for stopping the machine.S/N TFH : When the transmission is engaged, the elevated engine idle during regeneration will require a slightly increased effort to the service brake pedal. During a sustained full stop, this increased effort is not required when the transmission is shifted into neutral.Note: If the machine will remain stopped, shift the transmission into neutral and engage the parking brake.Disengage - Release the pedal in order to disengage the service brakes.Use correct gear selection and the engine compression brake in order to control the speed of the machine on downgrades. Supplement the engine compression brake with the service brakes if the machine requires additional retardation to avoid an engine overspeed.Note: Repeated engagement of the service brakes on downgrades may cause excessive wear and overheating of the service brakes. Refer to Operation and Maintenance Manual, "Engine Compression Brake Control".Note: The service brake is the primary braking system on the machine. Also, in the event of failure within the service brake system, the service brake control provides the secondary brake function on the machine in order to allow the operator to bring the machine to a stop.
