4. Recovery Operation from Auto Stop
The recovery operation from overloading should be the reverse operation of the crane operation that
caused the auto stop. Perform one of the followings.
(1) Lower the hook and put down the hoisted load on the ground.
(2) Retract the boom.
5.When recovering by boom raising operation
In the case of an automatic stop, when raising of the boom is
unavoidable, the boom raising operation is possible only while
keeping the boom lift bypass switch in the “ON” position.
To return to the “OFF” position, also return the boom raising lever.
Only use this switch when an automatic stop has occurred
through entry into the overload region while lowering or
extending the boom.
Do not use under normal conditions or when lifting clear
from the ground.
If you use this switch when lifting from the ground, there is
a risk of serious accidents such as the machine being
damaged or overturning.
