Test the Platform Self-leveling
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 and
lower the boom into the stowed position.
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 primary boom through
a full cycle.
Result: The platform should remain level at
all times to within ±5 degrees.
