How to Use AML Override Switch and
Override Key Switch
If restoring operations after a failure message appears
does not normalize crane operations, the AML is in trou-
ble. When the system is out of order, crane operation
becomes impossible.
The AML override switch and override key switch are
only intended for use to stow the boom. Insert the key
into the key hole and turn the switch to ON. The crane
operation is available and the AML cancellation warning
lamp lights up while the AML override switch is kept in
the ON position in this condition.
◆ The key should be kept by a person who takes care of
the crane, or a person responsible for job-site works.
How to Use Emergency Outrigger Control
Switch
When the outrigger extension detection device, such as
a code reel, breaks down, the registered outrigger state
in the AML is cancelled to make the crane inoperable. In
this emergency, use the emergency outrigger control
switch to register the outrigger state into AML, and the
indicator lamp will light up.
1.
Set the emergency outrigger control switch to ON.
The emergency outrigger control indicator lamp will light
up and the outrigger state on the AML will be set to the
default status.

Keeping the AML override switch set to ON and
the override key switch set to ON cancels the
AML's safety feature, the stop function. Using
these switches during normal operation is ex-
tremely dangerous. Do not use these switches
during normal operation. Use the switches only
when operation has been disabled due to failure
of the AML system. Be sure to set the load on the
ground and retract the boom before using the
switch. Use the elevating and/or swing functions
to stow the boom.
