THE HAND THROTTLE CABLE PASSES THROUGH THE ACCELERATOR ROD ASSEMBLY AT AN ANGLE THAT WEARS A GROOVE IN THE ROD, WHICH IS LOCATED UNDER THE ACCELERATOR PEDAL. THE CABLE CAN BECOME WEDGED IN THE GROOVE WORN INTO THE ROD AND CAUSE THE ACCELERATOR TO STICK IN AN OPEN POSITION.

Consequence

THIS CAN RESULT IN LOSS OF CONTROL OF THE BUS, AND COULD RESULT IN AN ACCIDENT.

DEALERS WILL INSTALL A POSITIONING BRACKET FOR ROUTING THE HAND THROTTLE CABLE THROUGH THE ACCELERATOR ROD ASSEMBLY.
