B-10
Test the Ground Control
Override
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
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 Emergency Stop button
on 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 platform red Emergency Stop button
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.
B-11
Check the Oscillate Directional
Valve Linkage
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Note: Perform this test only on models equipped
with a oscillating axle.
Proper axle oscillation is essential to safe machine
operation. If the oscillate directional valve linkage is
not operating correctly, the stability of the machine
is compromised and it may tip over.
1 Remove the drive chassis cover from the
non-steer end of the machine.
2 Locate the oscillate directional valve inside of
the non-steer axle and inspect the linkage for
the following:
• Lock nut is tight against yoke
• Yoke clevis pins are installed
• Cotter pins are installed through clevis pins
• Linkage is properly attached to
directional valve
