• Level the truck crane with the outriggers until the lamp (1) is the only one
illuminated in the measuring range 1°.
Switching off the suspension

Danger of overturning if outriggers are retracted
Always leave the outrigger beams extended and the outrigger pads just
above the ground to secure the truck crane against overturning.
