HOW TO OPERATE CRANE
Insert each set pin securely
when the outriggers are being
stored and set up on the ground.
Insufficient insertion of the set
pins allows a set pin to come
off which in turn may make the
crawler to lose balance causing
the crane to be overturned.
10
Turn the operation mode switch to
“crane”.
The voice message, “Crane mode, Crane
mode”, is heard and the yellow lamp goes
off.
11
Unwind the hook by controlling
the hook winding up/down lever to
loosen it from its stored position.
Do not stand under or in front of the hook as
it may swing during this operation.
Unwind the hook until the weight for over-
winding alarm is detached from the hook and
the alarm buzzer stops sounding.
This can start the crane operation.
WARNING
Before operating the crane it is
mandatory to set up all the out-
riggers.
