DESCRIPTION AND USE OF OPERATOR CONTROLS AND INDICATORS - CONTINUED
SERVICE BRAKE CONTROL (PEDALS) - CONTINUED
Left Brake Pedal Operation
Functions of left brake pedal depend on position of left brake pedal and on position of autoshift switch.
Initial travel (A)
Downshifting and service brake application (B)
Additional travel (application of service brakes) (C)
Calibrated initial brake pressure point (D)
Pedal position for stopping the machine (F)
Maximum pedal travel (full application of service brakes) (G)
Initial travel (A) of left brake pedal will cause transmission to aggressively downshift. Transmission will downshift to
lowest available speed. Lowest available speed depends on position of autoshift switch. Refer to Modes of Operation for
Transmission Neutralizer table later in this work package for lowest available speed. Each downshift of transmission will
reduce speed of machine. The transmission will downshift at higher speeds than normal automatic downshift speeds. The
transmission will only downshift if an engine overspeed will not occur. The transmission will not upshift until left brake pedal
is fully released.
The transmission will be engaged again after left brake pedal is released 4 degrees from pedal position (F). This will only
happen if transmission was neutralized. Service brakes will still be applied. This will allow transmission to be engaged when
brakes are applied. This will help to prevent unwanted movement while operating on a slope.
