Rotating the Superstructure
To rotate the superstructure, use the controls on the left-hand
armrest:
DANGER
Tipping Hazard!
Always check before rotating the superstructure whether
it is permitted in the crane's current rigging mode
(counterweight, outrigger span, working radius).
Before activating swing, sound the horn and verify that all
personnel are clear of rotating and moving parts.
Death or serious injury could result from being hit by the
load or moving machinery.
CAUTION
Machine Damage Hazard!
Disengage the swing brake and the swing lock pin and/or
360° swing lock before attempting to swing.
Never push or pull the swing control lever through neutral
to the opposite direction to stop swing motion. Use the
swing brake foot pedal to stop swing rotation.
Do not accelerate the slewing speed to such a degree that
the load starts swinging.
Damage to the crane may result from improper swing
operation.
1. Push the top of the Swing
Gear switch once.
2. ECOS indicator must be
green.
NOTE: If an RCL code has been entered for the working
position 180° to the rear or Free-on-wheels, an
RCL shutdown will occur after switching on the
swing gear, and rotation will be disabled. To
acknowledge the shutdown, you must either switch
off the swing gear or set down the load and enter
an RCL code for the 360° working range.

brake or leave the control
lever at the neutral
position, depending on
which control is selected
