Levelling the truck crane
• Retract the supporting cylinders evenly. Lower the truck crane only to the
extent that the suspension struts still have enough play for alignment.
• 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
• Switch off the suspension – the symbol must be red; à Switching the
suspension on/off
, p. 5 - 16.
To secure the truck crane
• Retract the supporting cylinders until the outrigger pads are
about 5 to 10 cm (2 to 4 in) above the ground. Allow the outrigger
beams to extend as far as possible.

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