5.7 MACHINE SAFETY SYSTEM OVERRIDE (MSSO)(CE
ONLY)
The Machine Safety System Override (MSSO) is
only to be used to retrieve an operator that is
pinned, trapped, or unable to operate the
machine and function controls are locked out
from the platform due to a platform overload sit-
uation.
NOTE: If the MSSO functionality is used, the fault indicator will flash
and a fault code is set in the JLG Control System which must be
reset by a qualified JLG Service Technician.
NOTE: No functional checks of the MSSO system are necessary. The JLG
Control system will set a Diagnostic Trouble Code if the control
switch is faulty.
To operate the MSSO:
1. From the ground control console, place the Platform/
Ground Select switch in the Ground position.
2. Pull out the Power/Emergency Stop control.
3. Start the engine.
4. Press and hold the MSSO switch and the control switch for
