PNEUMATIC PUMP SHIFT
The pump shift shall be air operated and shall incorporate an air double action piston to shift from road
to pump and back. A manual or electric operated pump shift mechanism is not acceptable. The pump
shift switch shall be mounted in the cab and identified as "AIR PUMP SHIFT" and include instructions
permanently inscribed on the pump shift switch plate. The in-cab operating valve uses a spring loaded
locking collar to prevent it from accidentally being moved.
The pump shift control assembly shall incorporate an indicating light system, which will notify the
operator when the shift has been completed to PUMP and when the chassis transmission is in correct
pumping gear.
The switch that activates the lights must be mounted on the pump transmission and positioned so that
the pump shift arm activates the switch only when the shift arm has completed its full travel into PUMP
position. An additional indicator light shall be on the pressure governor control at the pump operator's
panel to indicate a completion of the pump shift.

There shall be a manual override on the pump shift. The override control shall be activated from the
lower left side of the pump panel.
