Information
If the main boom has been telescoped several times, the telescoping
mechanism and derricking gear can be so heavily loaded that the main
boom can be neither telescoped nor derricked. Therefore note the following
instructions:
•
Before retracting the boom, raise it to approximately 15°.
•
Do not lower the main boom below 0°.

Risk of overturning when telescoping if the RCL is overridden.
Do not override the rated capacity limiter (RCL) when telescoping is
switched off. Select a suitable lifting capacity table which contains the
required telescoping. Set the associated rigging mode and enter the RCL
code.
G
Risk of accidents from slipping off the main boom.
There is grease residue on the telescopic sections. For this reason,
you must not walk on the main boom.
Use the extendable ladders provided with your crane.
