Test the Ground Control
Override
A properly functioning ground control override is
essential to safe machine operation. The ground
control override function is intended to allow ground
personnel to operate the machine from the ground
controls whether or not the red Emergency Stop
button at the platform controls is in the on or off
position. This function is particularly useful if the
operator at the platform controls cannot return the
boom to the stowed position.
1 Push in the red Emergency Stop button at the
platform controls to the off position.
2 Start the engine from the ground controls.
3 At the ground controls, operate each boom
function through a partial cycle.
Result: All boom functions should operate.
