8.5 OVERRIDE OPERATION IN
OVERLOADING
Override operation in overloading is only applicable for
overseas models.
With the machine in the KG mode, if an overload alarm
is triggered and the platform needs to be lowered, the
override operation in overloading should be activated.
• Perform operation from the ground: Activate the de-
sired movement switch while flipping the emergency
power switch on the ground controller;
• Perform operation from the platform: Depress the
foot switch, flip the emergency power switch on the
platform controller, and activate the desired move-
ment switch.
Then, the machine will activate the override operation,
and the corresponding movement can be performed.
The time of the override operation and the actual weight
on the platform are recorded on the display.
NOTICE
Override operation can only be used to lower the
platform in an emergency state after the platform is
overloaded, and before operating the machine to
perform the required action, please confirm that the
surrounding environment and the whole machine are
safe.
Before conducting any override operation, try to
avoid operation in directions where the machine
may tip over. Improper operation may cause the
machine to overturn, causing serious machine
damage and casualties.
