Machine Safety System Override (Msso) (If Equipped) - JLG EC450AJ Operation & Safety Manual

5.6 MACHINE SAFETY SYSTEM OVERRIDE (MSSO) (IF
EQUIPPED)
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. The MSSO
will override function controls that are locked out from the platform and
ground consoles. An example of this would be in the case of Load Sense System
activation.
Note: If the MSSO functionality is used, a fault indicator is set with a fault code 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.
Note: If the engine is not running, MSSO will function through the Auxiliary Power
system.
To operate the MSSO, perform the following:
1. From the Ground Control Console, place the Platform/Ground Select switch into
the Ground position.
2. Pull out the Power/Emergency Stop control switch.
3. Start the engine.
4. Press and hold the MSSO switch and the control switch for the desired function.
