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 primary boom raising and lowering is
essential for safe machine operation. The platform
is maintained level by the communication between
the platform level sensor and the turntable level
sensor. If the platform becomes out of level, the
computer at the ground controls will open the
appropriate solenoid valve(s) at the platform
manifold to maintain a level platform.
A platform self-leveling failure creates an unsafe
working condition for platform and ground
personnel.
1 Start the engine from the ground controls.
2 Press and hold a function enable/speed select
button and fully retract the primary boom.
Press the enter or previous button on the
3
LCD screen until PLATFORM ANGLE is
displayed
4 Press and hold a function enable/speed select
button and adjust the platform to zero degrees
using the platform level up/down buttons.
