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 so that the lifting cylinders can be
freely extended.
Assuming the symbol (4) is yellow with the
counterweight unrigged.
• Press in the override button (3).
• (A) Fully extend the lifting cylinders –
symbol (1).
• Release the override button (3).
• (B) – Fully retract the lifting cylinders –
symbol (2).
The symbols (4) become green.
You can now use the automatic mode.
S
Risk of damage to the counterweight!
With the override switch actuated, the functions are always enabled.
Slew the superstructure only when the lifting cylinders are fully retracted.
