8.3.1 SLEWING OPERATION
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.

Push the Slewing/No.1 outrigger operation lever to “Counter
clockwise (upper)”, then pull the Accelerator lever slowly.

the Crane from the sky.
[3] STOP SLEWING
Release the Accelerator lever slowly, then release the
Slewing/No.1 outrigger operation lever to return it to its neutral
position.
The boom stops slewing.
