Operation for Boom Retraction
DANGER! For stowing fly-jib, main-boom
should be lowered to the angle less than 55°
and retracted to a boom length of less than
12.5m. However, such condition is very
dangerous because Rated load display or
Actual load display do not work. Never lift
load under such condition, otherwise a
critical accident or damage to fly-jib may
result.
Main-boom is allowed to be stowed only under
the condition below in fly-jib mode.
[Boom length must be less than 12.5m (Two
stages of main boom are fully extended to
maximum.)]
Under this condition, boom lowering is available.
For stowing, retract the boom first, then control
the boom to stow position. In any event,
however, lifting in such a configuration is
prohibited because Rated load display (2) of
moment limiter only indicates "E-J".
TRANSPORTATION
Observe the related laws and regulations and
transport the machine safely.
Transport Precautions
Cautions When Loading or Unloading
• Be especially careful when loading or unloading
the machine because the risks intervene.
• Select a location that is level and has firm road
surface when loading or unloading the
machine. In addition, keep enough distance
from the roadside.
• Use the ramps under 15 degrees or smaller
angle. In addition, decide the clearance
between ramps to meet the centre of the rubber
tracks.

• Always set the machine in the "travelling
posture" and securely insert the position pins (4
pieces) to the outrigger rotary parts before
loading or unloading the machine.
For more information, see "TRAVELLING
POSITION" on page 4-23.
