Cautions When Placing Outrigger
Always observe followings to prevent serious
injuries and death accidents when placing the
outriggers.
• Do not let people approach nearby when
placing the outriggers.
Otherwise, serious accidents for instance the
outrigger support catching a foot may occur.

• Verify that the Moment Limiter Override Switch
is at the “OFF” position.

• When extending the outriggers and bringing
them in contact with the ground, be sure to set
the outrigger rotaries to the extended position
and to insert each position pin all the way in.
Do not bring the outriggers into contact with the
ground when the outrigger rotaries are stowed.
• When placing the outriggers, always keep the
machine sternly level while looking at the level
gauge. Occasionally view the level gauge and
make sure to keep the machine level during the
crane works as well.

• Place the outriggers at a maximum extension
condition as the basic rule.
If it is not possible to extend the outriggers to
their maximum positions for some reason,
operate the crane using the values given in the
"Outrigger medium extension rated total load
chart" or "Outrigger minimum extension rated
total load chart" columns of the rated total load
chart.

• Place the outriggers in a style that the rubber
tracks are approximately 50 mm above the
ground.

• Make sure all of the outrigger position pins are
securely fixed.
WARNING!
• Make sure all the outriggers are placed
properly before performing crane operation.
This machine features a safety-interlock
system that prevents crane operation
unless all the lamps, other than the boom
stowing lamp on the outrigger monitor, are
on.
• Always place the machine in a horizontal
position with the use of the level when
extending the outriggers. A warning buzzer
sounds when the machine is inclined 3° or
more and stops when the machine is placed
in a horizontal position.
