counterweight combination of 7.6 t (16,700 lbs) is rigged. If you wish to move the
rigged truck crane with a rigged counterweight combination of 8.6 t (18,900 lbs),
then you must first adequately support the truck crane and slew the superstruc-
ture into the 0° to the rear operating position.
• Bring the truck crane into a permissible Free on wheels operating position in
accordance with the Lifting capacity table;

A maximum counterweight combination of 8.6 t (18,900 lbs) may be rigged.
• Enter and confirm the current rigging mode at the RCL for the Free on wheels
operating position.
• For reasons of safety, extend the outrigger beams in accordance with the avail-
able space. The outrigger pads must not touch the ground whilst the crane is
being driven.
• You can drive without a load and, under certain circumstances, even with a
lifted load. Observe the information in the corresponding section.
