Using Emergency Descent In Case Of An Outrigger Losing Contact With The Ground - JLG X1000AJ Operation And Safety Manual

SECTION 5 - EMERGENCY PROCEDURES
Using Emergency Descent In Case Of An Outrigger Losing
Contact With The Ground
One or more of the outriggers may loose contact with the
ground which will result in the platform control box func-
tions being inoperable except for emergency lowering.
To restore platform control box functions, lower and retract
the booms and then reposition the machine and properly
set the outriggers.
Use the emergency descent from the platform if possible by
using the following sequence, fully retract main boom, fully
lower jib and fully lower main boom.
If this is not possible, have a properly trained person on the
ground bypass the platform safety devices and allow the
operator in the platform to lower and retract the booms or
allow emergency operations to bring the platform back to
the ground.
1. Remove key and insert it into the bypass key
switch (1). Turn switch (right/left) and hold to
activate bypass button (2). The bypass icon will
be displayed.
2. Press the bypass button (2) to
activate bypass mode and operate
the appropriate functions to bring
the machine to safety while keeping
bypass key turned.
5-8
3. Operate the machine from the platform control
ONLY carrying out operations that allow the tower
boom lowering, main boom retract and jib lower-
ing. The main boom must be fully retracted prior
to operating swing and main boom lowering func-
tions.
4.
After operation, return bypass key to its neutral
position and return key to its fastener.
NEVER PERFORM OPERATIONS DIFFERENT TO THOSE LISTED OR THAT CAN
IN SOME WAY REDUCE THE STABILITY OF THE MACHINE. THE ORDER OF THE
BOOM MOVEMENTS MUST BE DONE IN A WAY TO PREVENT ANY OPERATION
THAT REDUCES THE STABILITY OF THE MACHINE.
5. Once booms and jib are fully lowered and aligned,
release the key and secure the key to the emer-
gency ground control box.
If machine is set up in the reduced stabilization area, bypass-
ing the safety devices does not allow the boom to go out of
the working area related to that outrigger configuration.
