How to store hook
• Since releasing the hook from
its stored position allows it to
swing, it may cause an acci-
dent if a person stands under
or in front of the hook.
In addition, excessive pulling
of the “speed lever” increases
the hook to swing that is dan-
gerous so that do not pull the
lever extremely.
• It is strictly prohibited to oper-
ate the crane with the “storing
hook” as this is very danger-
ous.
• Retract the boom fully and
lower it to its extreme to store
it.
• Do not operate the “storing
hook” with any one of control
levers at the same time.
This may cause an incorrect
action and/or a breakdown of
the crane.
• Pay attention that the manu-
al control lever for “hook Up/
Down” moves “Up” side when
retracting the hook.
