Work Selector Switch (Travel, Outrigger,
Crane)
WARNING!
• When operating the work selector switch to
the "Travel" position, be sure to stow the
crane and put the machine in the "travelling
posture". Driving the machine not in the
"travelling posture" can overturn the
machine, resulting in serious accidents.
• Be sure to operate the travelling lock lever to
the "LOCK" position before outrigger or
crane operation.
• Note that if the travelling lock lever is not at
the "LOCK" position, you can still travel the
machine even if the work selector switch is
operated to the "Outrigger" or "Crane"
position. The machine may move, causing
serious accidents.
• Be sure to set all the outriggers when
turning the work selector switch to the
"Crane" position to perform the crane
operation. Inappropriate setting of
outriggers will prevent the crane operation
because of the outrigger safety device
function.
• Always stow the boom when performing the
outrigger operation with the work selector
switch set to the "Outrigger" position. If the
boom is not stowed properly, the outrigger
safety device function prevents the
outrigger operation from being performed.
Use this switch to switch the work state of the
machine (Travel, Outrigger, Crane).
• Travel: Push down the switch to the left.
Now you can travel the machine.
• Outrigger: Push down the switch to the centre
position. Now you can perform the
outrigger operation.
• Crane: Push down the switch to the right.
Now you can perform the crane
operation.
