6. OPERATION
When using a crane, remember to set the engine in low idling mode and work in a speed as low
as possible. If you operate a lever in a sudden motion, the fly jib might break due to the excess
force, causing a serious accident.
CAUTION
In this section, only the operations in the fly jib specification different from the standard
specification are described.
See “Operation 2. Operation” for details on the operation of the machine not described here.
When operating the fly jib, push the monitor operation switch
to change to the fly jib operation.
6.1
FLY JIB DERRICKING OPERATION
Operate the right operation lever (1) as follows:
• Lower : Push the lever forward.
• Neutral: Release your hand from the lever.
The lever returns to the NEUTRAL position and the fly
jib derricking stops.
• Raise : Pull the lever to the rear side.
6.2 FLY JIB RETRACT/EXTEND OPERATION
Operate the left control lever (2) as follows:
• Extension : Push the lever forward.
• Neutral : Release your hand from the lever.
The lever returns to the NEUTRAL position and the
fly jib telescoping stops.
• Retraction: Pull the lever toward you.
NOTES
• To move the fly jib, you need to change the boom/fly jib operation selector on the monitor. For details
on the switch, see “Fly jib 5.1.1 Monitor display in fly jib mode”.
• You cannot perform the extend/retract operation and the derrick operation of the fly jib at the same
time. Either of the preceding operation is executed. The rotation and winch operations can be
performed simultaneously.
