NOTE When the ALL jacking switch is used, the crane’s

Prior to using the ALL jacking switch, verify the
accuracy of the rotating bed level sender with an
user furnished digital level. The TILT RIGHT and
TILT FRONT angles shown on the digital display
should be the same as the angles shown on the
digital level.
The CRANE LEVEL operating limit will appear on
the digital display and the swing and travel alarm
will sound if the rotating bed gets 3° out of level
while jacking.
• Operation does not stop automatically when
this alarm comes on.
• When this alarm comes on, operator shall
stop jacking and level rotating bed using
individual jacking switches.
If the rotating bed level sender indicates that the
rotating bed is more than 4.7° out of level, the
CRANE LEVEL SENSOR system fault will appear
on the digital display, the swing and travel alarm will
sound, and the ALL jacks switch will be disabled.
The rotating bed should then be leveled using the
