Risk of overturning while slewing.
Always check before slewing whether slewing is permitted in the truck
crane's current rigging mode. Correct the rigging mode if necessary;

Slewing with rigged counterweight , p. 12 - 97.
G
Danger of overturning when slewing with an overridden RCL
Do not override the RCL before slewing the superstructure.
If slewing is not enabled then, for the
Standard slewing range type enter a
rigging mode for the 360° working range or for the MAXbase slewing range
type enter a working radius for which slewing is enabled.
This prevents slewing into impermissible areas and the truck crane tipping
over as a result.
S
Risk of damage to the separate vehicle
Raise the hook block from the separate vehicle only when the main boom
head is directly above the hook block.
This prevents the hook block 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 damaged.
