CHECKLIST B PROCEDURES
B-13
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 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.
B-14
Test the Platform Self-leveling
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Automatic platform self-leveling throughout
the full cycle of boom raising and lowering is
essential for safe machine operation. The
platform is maintained at level by the platform
leveling slave cylinder which operates in a closed
loop hydraulic circuit with the master cylinder
located at the base of the boom.
A platform self-leveling failure creates an unsafe
working condition for platform and ground
personnel.
1 Start the engine from the ground controls.
2 Hold the function enable toggle switch to either
side and adjust the platform to a level position
using the platform level toggle switch.
3 Raise and lower the boom through a full cycle.
Result: The platform should remain level at
all times to within ±5 degrees.
