Slewing Operation
WARNING! At the slewing operation, actuate
the Accelerator lever carefully and always
keep in low speed.
Also, actuate the Accelerator lever slowly and
delicately to avoide abrupt slewing.
Such abrupt acceleration or deceleration
especially while a load is hung will make a
large impact to the Crane and may result a
serious hazard such as Crane tipping or
damage.
