Danger of overturning if the truck crane is free-standing!
When the truck crane is free on wheels, the superstructure may not be
slewed.
For the free on wheels working position, the truck crane is first supported and
fully rigged. The truck crane is then placed on the wheels.
For this reason, always follow all items in this checklist.
This prevents the truck crane overturning when slewing.
