Selecting Operational Status
Selecting Outrigger Status
◆ The "on-rubber" state indicative symbol is marked up
when the power supply is turned on (the PTO switch in
the carrier driver’s cab is turned ON after the engine is
started). (The outrigger state indicative symbols and
front jack symbol remain off.)
◆
Turning the power off (PTO switch: OFF) automatical-
ly erases all the previous settings stored in memory after
approximately 2 hours. To resume the operation more
than 2 hours after the power has been last turned off,
enter the settings all over again.
Register the outrigger status using the outrigger mode
select key and register key.
When the outrigger mode select key is pressed, the out-
rigger state indicative symbols and front jack symbol
flash in accordance with the status that the AML detects
on.
After making sure that the display conforms to the actual
outrigger conditions, press the register key. The outrig-
ger state indicative symbol will change from flashing into
being marked up continuously and the moment display,
rated lifting capacity display and real load display will re-
turn to normal display conditions, meaning that the state
has been registered.
◆
If an outrigger or the front jack is stowed after registra-
tion of outrigger status, the registered status is erased.
In this case, register the outrigger status again before
starting crane operation.

Should the operational status be incorrectly
registered, the crane might overturn or be dam-
aged, leading to a serious accident. Prior to every
operation, check that the registered status corre-
sponds to the actual status of the crane.
