crane's current rigging mode. Correct the rigging mode if necessary;

G
Danger of overturning when slewing with an overridden RCL
Do not override the RCL before slewing the superstructure.
Enter an RCL code for the 360° working range if the slewing operation is not
released.
This prevents the superstructure from being slewed into impermissible
areas and the truck crane tipping over as a result.
S
Risk of damage to the separate vehicle
Only raise the hook block from the separate vehicle if the main boom head
is directly above the hook block.
This prevents the hook block from swinging and damaging the separate
vehicle.
S
Risk of damage to the hoist rope
To prevent slack rope, do not ease down too much hoist rope when picking
up and reeving the hook block!
Slack rope causes rope loops on the hoist drum, which can result in the load
slipping and the hoist rope being destroyed.
