Correct the rigging mode
• You can use the automatic mode only if the
current rigging mode is displayed.
If necessary, correct the displayed rigging
mode as follows:
• Slew the superstructure out of the rigging
range – display (3) – so that the lifting cylin-
ders can be freely extended.
Assuming the symbol (1) is yellow with the
counterweight unrigged.
• Turn the key-operated switch (5) to the left.
• (A) Fully extend the lifting cylinders –
button (4).
• Let go of the key-operated switch (5).
• (B) – Fully retract the lifting cylinders –
button (3).
The symbol (2) turns yellow – counterweight
unrigged.
You can now use the automatic mode.
1 Yellow – counterweight rigged
2 Yellow – counterweight unrigged
