IF A PERSON OPERATING THE ENGINE FROM THE "REAR" POSITION (AT THE ENGINE) FAILS TO PLACE THE SWITCH IN THE "OFF" OR "FRONT" POSITION AND THE ENGINE RPM WAS SET TO ABOVE IDLE DURING MAINTENANCE FOR EXAMPLE, WHEN THE BUS IS STARTED FROM THE DRIVER'S STATION THE ENGINE COULD CHANGE TO THE HIGHER RPM RESULTING IN UNWANTED ENGINE POWER.

RiskTHE BUS COULD ACCELERATE AT A HIGHER RATE THAN ANTICIPATED INCREASING THE RISK OF A CRASH.

POTENTIAL LIFT PUMP FAILURE MODES INCLUDE: BRUSH WEAR OUT, BUSHING FAILURE, ROTOR TAB INSERT FAILURE, OR ANY OTHER FAILURE MODE THAT WOULD CAUSE THE FUEL PUMPING ELEMENT TO STOP SPINNING.

RiskIF THE FUEL LIFT PUMP PUMPING ELEMENT STOPS SPINNING AND THE FUEL PUMPING VANES STOP IN A LOCATION WHICH BLOCKS FUEL FLOW THROUGH THE LIFT PUMP, THE ENGINE WILL BE STARVED OF FUEL. FUEL STARVATION COULD CAUSE LOW ENGINE POWER, ENGINE MISFIRE, OR ENGINE STALL.
