Manual alignment • Check that the prerequisites are met; à p. 12 - 44.

• Level the truck crane with the supporting cylinders until the lamp (1) is the only
one lighting up in the measuring range 1°;
à p. 12 - 39.
• Only lift the truck crane as far as necessary.
Checks to be performed after levelling
During levelling, the ground may give way and the packing may slip.
• After you have levelled the truck crane, check:
– that all the wheels are lifted off the ground.
– that the ground has not given way under any of the outrigger pads,
– that the packing is correct for the enlarged load-bearing area.
If slewing is permissible in the current rigging mode:
• Slew the superstructure within the permissible slewing range.
• Perform the specified checks again.
• Check the horizontal alignment on the inclination indicator.
