Level Gauge
WARNING! When installing the outrigger,
make adjustments while looking at the level
so that the machine body will be levelled.
Performing the crane operation with the body
tilted will cause overturning.
This device indicates how much the machine
body is tilted.
The bubble position shows how much the
machine is tilted in which direction.
Use this device to verify that the machine is
levelled when setting the outriggers.

• If the extension or setting of one of the four
outriggers cannot be detected, the outrigger un-
set warning lamp flashes.
• The outrigger un-set warning lamp is linked

flashes, the working status lamp (red) also
